Some people cannot smell well. Some people cannot smell
the odor of the chemical stench put into the gas. You must
find out if you can smell the odorant in propane. Smoking
can decrease your ability to smell. Being around an odor for
a time can affect your sensitivity or ability to detect that odor.
Sometimes other odors in the area mask the gas odor. People
may not smell the gas odor or their minds are on something
else. Thinking about smelling a gas odor can make it easier
to smell.
The odorant in LP-gas is colorless, and it can fade under
some circumstances. For example, if there is an underground
leak, the movement of the gas through soil can filter the odorant.
by point with the members of your household. Someday
when there may not be a minute to lose, everyone's safety
will depend on knowing exactly what to do. If, after read-
ing the following information, you feel you still need more
information, please contact your gas supplier.
Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precau-
tions which can protect both you and your family from an
accident. Read them carefully now, then review them point
Odorants in LP-Gas also are subject to oxidation. This fading
can occur if there is rust inside the storage tank or in iron gas
pipes.
The odorant in escaped gas can adsorb or absorb onto or into
walls, masonry and other materials and fabrics in a room. That
will take some of the odorant out of the gas, reducing its odor
intensity.
LP-Gas may stratify in a closed area, and the odor intensity
could vary at different levels. Since it is heavier than air, there
may be more odor at lower levels. Always be sensitive to the
slightest gas odor. If you detect any odor, treat it as a serious
leak. Immediately go into action as instructed earlier.
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it
to find out what the propane odor smells like. If you suspect
that your LP-Gas has a weak or abnormal odor, call your
LP-Gas Dealer.
• If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualified, consciously think about the
odor of LP-Gas prior to and while lighting pilot lights or
performing service or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilot lights, perform service, or make adjustments in an area
where the conditions are such that you may not detect the
odor if there has been a leak of LP-Gas.
• Odor fade, due to oxidation by rust or adsorption on walls
of new cylinders and tanks, is possible. Therefore, people
should be particularly alert and careful when new tanks or
cylinders are placed in service. Odor fade can occur in new
tanks, or reinstalled old tanks, if they are filled and allowed
to set too long before refilling. Cylinders and tanks which
have been out of service for a time may develop internal rust
which will cause odor fade. If such conditions are suspected
to exist, a periodic sniff test of the gas is advisable. If you
have any question about the gas odor, call your LP-gas
dealer. A periodic sniff test of the LP-gas is a good safety
measure under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the
same immediate action recommended above for the occasion
when you do detect the odorized LP-Gas.
• If you experience a complete "gas out," (the container is un-
der no vapor pressure), turn the tank valve off immediately.
If the container valve is left on, the container may draw in
some air through openings such as pilot light orifices. If this
occurs, some new internal rusting could occur. If the valve is
left open, then treat the container as a new tank. Always be
sure your container is under vapor pressure by turning it off
at the container before it goes completely empty or having
it refilled before it is completely empty.
SAFETY INFORMATION FOR USERS OF LP-GAS
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area.
Do that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such
as basements. When you have reason to suspect a gas leak,
keep out of basements and other low areas. Stay out until
firefighters declare them to be safe.
• Use your neighbor's phone and call a trained LP-Gas service
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
SOME POINTS TO REMEMBER
NO ODOR DETECTED - ODOR FADE
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!

INSTALLATION PLANNING
Plan the furnace installation with three questions in mind:
1. Where is the heat most needed in the house?
2. Where should the furnace be so that it will vent properly?
3. Where should it be placed so that it is not in home traffic
areas or walkways?
Remember! Good Venting is essential to Good Heating.
VENTING
The installer must consider all of the following venting rules. They
will help plan where and how to install the furnace.
1. Flue pipe MUST always have an upward slope (1/4 inch per
foot minimum) (see 1).
1
2. Flue pipe MUST NOT have any downward sloping sections,
dips or sags (see 2 and 3).
3. Flue pipe MUST be Type B (double wall insulated).
2
3
NOTE
Do not use Type C single wall flue pipe.
Uninsulated single-wall metal pipe shall not be used out-
doors in cold climates for venting gas utilization equip-
ment.
4. For flue pipe running through walls, roof and within one (1)
inch of combustible construction, use B-1 (one inch clearance
to combustibles) vent pipe (see 4). Any combustible mate-
rial that is within 6 inches of the vent connection or the draft
diverter must be shielded with a non-combustible material.
4
5. Flue pipe MUST run as directly as possible and have as few
elbows as possible.
6. Flue pipe MUST be as large as the flue collar on the draft
diverter (see 5).
7. The flue pipe MUST be on the outside of the draft diverter
collar (see 6).
8. Each new piece of flue pipe that is connected when getting
farther away from the furnace MUST connect on the outside
of the previous one (see 6). Remember, the exhaust must
flow "into" the next pipe.
9. The flue pipe MUST NOT be connected to a chimney that
has a fireplace connected to it (see 3).

12417-12416-2-0403 Page 5
Here are some suggestions.
1. If you have a choice, select a location close to the chimney.
2. If there is no chimney, you will have to run a flue pipe from
the furnace, up to and above the house roof (see 1). Select
a location permitting the most direct run. Try going up to
the roof through a closet. Remember that the flue pipe must
slope upwards at least 1/4 of an inch for each foot and you
may find floor joints in our path, so it is important to plan the
run carefully (see 8).
8
3. If you have decided to go up to the roof through a closet (see
9), remember that you MUST keep a minimum distance of 1
5
10. When connecting the flue pipe to the chimney, the pipe MUST
go fully in and be cemented (see 7). The flue pipe MUST
NOT go too far into the chimney. It should be cut off as it
will interfere with normal venting (see 7).
11. The flue pipe MUST be sealed. No open "Tees" (see 5).
6
12. The flue pipe's vertical rise MUST always be at least twice
the length of the horizontal run.

CUTTING THE FLOOR
HERE'S HOW TO DO IT
1. Place the template on the floor where you want the furnace
and draw an outline on the floor around the template. Recheck
the dimensions carefully.
2. Remove the template and drive a long nail through the floor
within the outline. If you hit a joist instead of going through,
try another spot within the outline.
3. Go below and find where the nail came through, so you will
know where the furnace will be located downstairs.
4. If the furnace location does not have to be exact, plan on
placing the furnace against one of the joists (see 10).
5. Cut out some of the floor along the joist so that you can look
through and see where you are. Use that joist and cutout
as a guide by laying the template along it, and draw a new
outline.
6. Cut away the flooring around the outline but do not cut the
joist yet. Remember that the joist has to be cut back farther
than the flooring to make room for the headers (see 10).
7. Place jacks or supports under the joist that is to be cut. This
will prevent the joist sagging and pinching the saw when you
are cutting.
8. Move any heavy furniture, or appliance (refrigerator) away
from the area where the joist is being cut. If not properly sup-
ported, the floor could sag and furniture could fall on you.
9. Cut through the joist at each end and remove. Put the header
in place (see 10) and jack it up against the floor. Make sure
it is butted up against the end of the joist you have just cut.
Use the template to make sure the header is square to the two
joists on each side of it.
10. Drive three large nails through each of the joists and into each
end of the header. Now drive three large nails through the
header and into the end of the joist just cut. Install the other
header in the same way (see 10).
11. Use the template to position the additional furnace support
(see 10) and then nail the support in place by driving three
nails into each end of it, through the headers.
12. Remove the jacks and supports.
13. Make sure the furnace is facing the way you want it with draft
diverter closet to the vent pipe chimney. Then, with someone
helping you, slowly lower it into the opening.
14. Drive two nails through each side and at least one nail through
each end of the furnace from the inside into each joist and
header that surrounds it.
inch between Type B vent pipe and any combustible material.
Run it through a single wall pipe that is 2 inches larger in
diameter than the flue pipe. Use thimbles when going through
floor and ceiling and flashing when going through roof.
4. Position the furnace so that the long sides are running the
same way as the floor joists (see 10), so that you will only
have to cut one joist. Be sure you install headers or cross
supports between each joist next to the one you cut (see 10). If
the furnace is narrow, you will have to also run an additional
furnace support between the two headers or cross supports
you add (see 10). There is a "Cutout Template" in the box the
furnace came in. It is the exact size for the opening needed
in the floor to fit the furnace. Use the cardboard template
when preparing and cutting the floor but always double check
the dimensions (see Table on next page). HINT: When you
cut the joist, don't forget to allow for the thickness of the
two headers you will install. Each one is about 1 1/2 inches
thick. Since you will be using two of them, that is a total of
3 inches.
5. If the house has a sealed or unventilated foundation, an open-
ing will have to be provided to admit air for burning at the
burner. The opening or vent MUST BE at least 1 square inch
per thousand BTUs. (The owner will also have to provide
a gate or door as an entrance to the crawl space so that the
serviceman can get to the bottom of the furnace for making
any necessary adjustments.) The furnace must have at least
6 inches clearance at the bottom.
6. If you have a completely open foundation strong winds will
cause your burner to flutter, make noise and cause the pilot
to go out. The best setting for a furnace is an enclosed but
ventilated foundation with an access door or gate.

12417-12416-2-0403 Page 7
Floor joists are on 16-inch centers. If you cut away one joist, the
next two are then on 32-inch centers. Because of the thickness
of the joists, that means there is about 30 1/2 inches of space
between them—just enough for the biggest floor furnace, Model
7088, which is 30 inches wide. The smaller furnaces will need an
additional support along the one side (see 10), or on both sides
if you are centering the furnace between two joists because loca-
tion is critical. If the location is not critical, it is easier for you to
put the furnace against a joist and then fill in with one additional
support.

INSTALLING DRAFT DIVERTER
The draft diverter mounts on the exhaust end of the furnace with
four #10 x 1/2" sheet metal screws. The holes are already drilled
in the furnace and the screws are supplied with the furnace. Make
sure collars of the diverter go outside the collars on the furnace.
When the diverter is tightened against the furnace, its collars
should be embedded into the gasket in the recesses.
After the installation of the diverter as shown, do not install walls
or partitions that would place the diverter in a different pressure
zone than the combustion air for the main burner.
DEBRIS PAN
A flat rectangular burner pan (debris pan) is attached to the burner.
This pan is designed to catch hot particles that might drop from the
combustion chamber. SEE LABEL ON SIDE OF FURNACE.
Method of Installing a Tee Fitting Sediment Trap
In the state of Massachusetts the gas cock must be a T handle
type.
To check the inlet pressure to the gas valve, a 1/8" N.P.T. plugged
tapping, accessible for test gauge connection must be placed imme-
diately upstream of the gas supply connection to the appliance.
GAS CONNECTIONS
1. A manual valve and ground-joint type union should be installed
close to the furnace for servicing.
2. A "drip" shall be put in the gas line to collect condensate or
dirt. This can be a "tee" fitting near the furnace inlet with an
extension downward that is capped.
3. Use a large enough pipe to prevent excessive pressure drop.
The pipe should be at least the size of the opening on the
furnace inlet.
The state of Massachusetts requires that a flexible appliance con-
nector cannot exceed three feet in length.
The gas inlet to the furnace is 1/2 inch nominal pipe thread. Use
at least 1/2 inch pipe to avoid excessive pressure drop; check lo-
cal codes. Install the piping in accordance with the requirements
described in Installation Planning.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections and,
if unexposed, a pressure test should be made. NEVER USE AN
EXPOSED FLAME TO CHECK FOR LEAKS. Appliance must
be disconnected from piping at inlet of control valve, and pipe
capped or plugged for pressure test. NEVER PRESSURE TEST
WITH APPLIANCE CONNECTED; CONTROL VALVE WILL
SUSTAIN DAMAGE.
TESTING THE SUPPLY PIPING
The appliance and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of
that system at test pressures in excess of 1/2 psig (3.5kPa).
The appliance must isolated from the gas supply piping system by
closing its individual manual shut off valve during any pressure
testing of the gas supply piping system at test pressures equal to
or less than 1/2 psig (3.5 kPa).
ATTENTION! If one of the above procedures results in pressures
in excess of 1/2 psig (14 in. w.c.) (3.5 kPa) on the appliance gas
valve, it will result in a hazardous condition.
WALL THERMOSTAT
No wire is supplied with the thermostat because the wire size
depends on low long the wire has to be.
FOR DISTANCE OF— 10' 30'
USE WIRE SIZE — 18-2 16-2
Thermostat is mounted to the wall with two screws that are sup-
plied. Mount the thermostat about 4 to 5 feet up from the floor,
in the room heated by the furnace, and exposed to normal free
air circulation.
Connect thermostat to gas valve terminals as shown in 14.

OPERATING INFORMATION
PIEZO LIGHTING INSTRUCTIONS
This unit is equipped with a Piezo (spark) for lighting the pilot
without removing the lighter hole cover. A lighter rod is supplied
and can be used to see if the pilot is getting gas and also for faster
lighting when there is excessive air in the lines.
REGISTER TEMPERATURE CONTROLS
The register temperature control has two positions. LOW HEAT
(Black) output and FULL HEAT (Red) output. Use the low posi-
tion when children are present. This will cause your furnace to
turn off and on several times before the living area is completely
comfortable. This is normal and limits the register temperature
to a maximum of 235°F.
CAUTION
Contact of bare skin on the hot air register may result in burns
when the appliance is in operation. KEEP CHILDREN OFF!
You can reduce the heat of the register by moving the register
temperature control.
MILLIVOLT INFORMATION
500 average with the thermostat OFF.
225 average with the thermostat ON.
140 minimum for valve to open.
65 minimum for pilot to stay on.
CAUTION: Label all wires prior to disconnection when
servicing controls. Wiring errors can cause improper and
dangerous operation. Verify operation after servicing.
A. All units have been fire-tested to check the operation of the
furnace. This includes the BTU input, main burner flame, pilot
flame, limit controls and automatic operation. If problems
are encountered on initial installation the following should
be checked
1. Is the unit equipped for the gas being used?
2. Are all of the wires connected to the gas valve prop-
erly?
3. Is the venting system functioning? Check for spillage at
the diverter.
4. Is the gas inlet pressure proper? Read instructions for
minimum pressure.
B. It is necessary to use a millivolt meter to determine if the
power from the generator is adequate. 500 millivolts is normal
with the thermostat off and 140 millivolts minimum with
thermostat on.
C. This floor furnace cannot be expected to function properly if
exposed to wind as found when installed in a house supported
by pillars (open foundation). The wind is most harmful if it
can go beneath the front of the draft diverter and produce a
pressure directly on the outlet of the chamber. This wind can
result in pilot outage and a reduction in millivolts, causing
the valve not to open.
D. Good operation of the system is dependent on the pilot and
generator working properly. It is possible for the pilot to
require cleaning yearly. Replace pilot assembly if cleaning
does not produce proper flame. Replacement on generator
alone is not recommended.
E. Gas Valve will not open. To determine problem area:
1. By-pass thermostat on the wall.
2. By-pass thermostat at the valve.
3. By-pass limit and thermostat at the valve.
4. Check millivolts.
TROUBLESHOOTING INFORMATION
SOME HELPFUL WARNINGS
• Use low heat output when children are nearby.
• Do not cover the floor register when the furnace or pilot is
turned on.
• Do not restrict the flow of air around the register by placing
a screen under it.
• Do not dry clothes or any objects by putting them on floor
register because this creates a fire hazard.
• Do not hang clothes or any object above or over floor register
because this too creates a fire hazard.
• During warm weather months, turn to full OFF position before
you cover the register with a rug, because this too creates a
fire hazard.
CAUTION
NEVER run your furnace with the lighter hole open or with a
broken lighter hole window. Exhaust gases can get into the living
area through an open lighter hole and be fatal.

HIGH ALTITUDES
Orifice size must be reduced for high altitude use, or carbon mon-
oxide may be generated and excessive heat will seriously damage
the unit. When altitudes over 2,000 feet are specified, in the United
States, main burner spuds will be furnished to reduce input 4% for
each 1,000 feet of altitude above sea level. Contact the manufacturer
or your gas company before changing spud sizes.
CHECKING MANIFOLD PRESSURE
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve with factory-set adjustment. Natural gas
models should have a manifold pressure of approximately 3.5"
w.c. at the valve outlet with the inlet pressure to the valve from a
minimum of 5.0" w.c. for the purpose of input of input adjustment
to a maximum of 7.0" w.c. Propane gas models will have a manifold
pressure approximately 10.0" w.c. at the valve outlet with the inlet
pressure to the valve from a minimum of 11.0" w.c. for the purpose
of input adjustment to a maximum of 13.0" w.c.
An 1/8" N.P.T. plugged tapping, accessible for test gage connection,
is located on the outlet side of the gas control.
CLEANING THE MAIN BURNER
Remove the burner and apply air pressure inside the throat of the
burner and down into the ports.
Check for proper burner and pilot flame before and during each
heating season.
SERVICING
INSTALLATION AND REPAIR SHOULD BE DONE BY A
QUALIFIED SERVICE PERSON. The appliance should be
inspected before use and at least annually by a professional service
person. More frequent cleaning may be required due to excessive
lint from carpeting, bedding material, etc. It is imperative that
control compartments, burners and circulating air passageways of
the appliance be kept clean.
Floor furnace must not be connected to a chimney flue servicing
a separate solid-fuel burning appliance.
DON'T put anything around the furnace that will obstruct the
flow of combustion and ventilation air.
DO keep the appliance area clear and free from combustible
material, gasoline and other flammable vapors and liquids.
DO examine venting system periodically and replace damaged
parts.
DO examine burners periodically. Clean and replace damaged
parts.
MAKE periodic visual check of pilot and burner flame.

Some people cannot smell well. Some people cannot smell the
odor of the chemical stench put into the gas. You must find out
if you can smell the odorant in propane. Smoking can decrease
your ability to smell. Being around an odor for a time can affect
your sensitivity or ability to detect that odor. Sometimes other
odors in the area mask the gas odor. People may not smell the
gas odor or their minds are on something else. Thinking about
smelling a gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under some
circumstances. For example, if there is an underground leak, the
movement of the gas through soil can filter the odorant. Odorants
in LP-Gas also are subject to oxidation. This fading can occur if
by point with the members of your household. Someday
when there may not be a minute to lose, everyone's safety
will depend on knowing exactly what to do. If, after read-
ing the following information, you feel you still need more
information, please contact your gas supplier.
Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following safety precau-
tions which can protect both you and your family from an
accident. Read them carefully now, then review them point
there is rust inside the storage tank or in iron gas pipes.
The odorant in escaped gas can adsorb or absorb onto or into
walls, masonry and other materials and fabrics in a room. That
will take some of the odorant out of the gas, reducing its odor
intensity.
LP-Gas may stratify in a closed area, and the odor intensity
could vary at different levels. Since it is heavier than air, there
may be more odor at lower levels. Always be sensitive to the
slightest gas odor. If you detect any odor, treat it as a serious
leak. Immediately go into action as instructed earlier.
• Learn to recognize the odor of LP-gas. Your local LP-Gas
Dealer can give you a "Scratch and Sniff" pamphlet. Use it
to find out what the propane odor smells like. If you suspect
that your LP-Gas has a weak or abnormal odor, call your
LP-Gas Dealer.
• If you are not qualified, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualified, consciously think about the
odor of LP-Gas prior to and while lighting pilot lights or
performing service or making adjustments.
• Sometimes a basement or a closed-up house has a musty
smell that can cover up the LP-Gas odor. Do not try to light
pilot lights, perform service, or make adjustments in an area
where the conditions are such that you may not detect the
odor if there has been a leak of LP-Gas.
• Odor fade, due to oxidation by rust or adsorption on walls
of new cylinders and tanks, is possible. Therefore, people
should be particularly alert and careful when new tanks or
cylinders are placed in service. Odor fade can occur in new
tanks, or reinstalled old tanks, if they are filled and allowed
to set too long before refilling. Cylinders and tanks which
have been out of service for a time may develop internal rust
which will cause odor fade. If such conditions are suspected
to exist, a periodic sniff test of the gas is advisable. If you
have any question about the gas odor, call your LP-gas
dealer. A periodic sniff test of the LP-gas is a good safety
measure under any condition.
• If, at any time, you do not smell the LP-Gas odorant and you
think you should, assume you have a leak. Then take the same
immediate action recommended above for the occasion when
you do detect the odorized LP-Gas.
• If you experience a complete "gas out," (the container is un-
der no vapor pressure), turn the tank valve off immediately.
If the container valve is left on, the container may draw in
some air through openings such as pilot light orifices. If this
occurs, some new internal rusting could occur. If the valve is
left open, then treat the container as a new tank. Always be
sure your container is under vapor pressure by turning it off
at the container before it goes completely empty or having
it refilled before it is completely empty.
SAFETY INFORMATION FOR USERS OF LP-GAS
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Get everyone out of the building, vehicle, trailer, or area.
Do that IMMEDIATELY.
• Close all gas tank or cylinder supply valves.
• LP-Gas is heavier than air and may settle in low areas such
as basements. When you have reason to suspect a gas leak,
keep out of basements and other low areas. Stay out until
firefighters declare them to be safe.
• Use your neighbor's phone and call a trained LP-Gas service
person and the fire department. Even though you may not
continue to smell gas, do not turn on the gas again. Do not
re-enter the building, vehicle, trailer, or area.
• Finally, let the service man and firefighters check for escaped
gas. Have them air out the area before you return. Properly
trained LP-Gas service people should repair the leak, then
check and relight the gas appliance for you.
SOME POINTS TO REMEMBER
NO ODOR DETECTED - ODOR FADE
LP-GAS WARNING ODOR
If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.
That's your signal to go into immediate action!

GENERAL INSTRUCTIONS
Follow a few simple rules and your Empire furnace will give
you years of trouble-free heating. When your furnace is ready
for installation, operation or repair here are a few DO's and
DON'T's.
DON'T install the furnace yourself if you are not qualified in
working with gas piping, chimneys, flue pipes, and venting. Gas
appliances and gas piping should be installed or repaired only by
a qualified serviceman.
DO get a qualified installing agency to install your furnace. By
the term "qualified installing agency" is meant any individual,
firm, corporation or company which either in person or through a
representative is engaged in and is responsible for the installation or
replacement of gas piping on the outlet side of the meter, or of the
service regulator when a meter is not provided; or the connection,
installation or repair of gas appliances, who is experienced in such
work, familiar with all precautions required; and has complied with
all the requirements of the authority having jurisdiction.
The installation must conform with local codes, or in the absence
of local codes, with the National Fuel Gas Code ANSI Z223.1.
*Available from the American National Standards Institute, Inc., 11 West 42nd
St., New York, N.Y. 10036.
DO consult your dealer and local gas supplier about qualified
installers and servicemen.
DO refer to your Empire Installer and Serviceman's Manual so
that you can make sure that all installation and service work was
done properly. You bought the best furnace, now make sure you
get the best service.
DO make sure your venting system and flue pipe were installed as
outlined in your Empire Installer and Serviceman's Manual.
DO see "Using Your Furnace" before you try to light the pilot or
turn your furnace on.
DO see "Using Your Furnace" for instructions on how to set the
register temperature control when children are present.
CAUTION
Floor register becomes hot when operating and can cause burns.
Keep children off!
DON'T adjust or repair the combination valve, and don't take it
apart.
DON'T try to make any repairs except the ones listed for you to
do in Service Checks.
DID YOU GET EVERYTHING?
After you have unpacked your Empire furnace, you should make
certain everything is in order. For example, did you receive the
model furnace you ordered? Is it the model for the type of gas
(Natural or Propane) you want? Did you get all of the parts you
are supposed to have? Look at picture A. It will tell you where
your furnace identification plate is. The plate has stamped on it
the model and serial number of the furnace you received. It also
tells if your furnace is supposed to use natural (NAT) or propane
(LP) gas. See if the serial number on your furnace is the same as
the number on the WARRANTY CARD. Be sure your dealer fills
out the WARRANTY CARD, then MAIL the purchaser's report
(bottom part) to us. Look at Picture A and also the list below to see
if you have received everything on the list. If anything is missing
or broken, or if the model or serial numbers are not right, or if
the furnace is for natural and you have propane (or the other way
around), contact your dealer or Empire Comfort Systems, Inc.

HOW YOUR FURNACE WORKS
HEATING
Your Empire furnace uses air from two places; air from outside
the living area, and air from inside the living area. The air from
outside the living area is mixed with gas and burned inside a
chamber in your furnace. The burned gas and air is exhausted
through a flue pipe to the outside air again. This exhaust should
not be permitted to enter the living area.
Burning gas inside the furnace chamber makes the chamber hot.
Cool air from inside the living area is drawn into the furnace and
flows past the outside of the hot chamber. The chamber makes this
air hot and this hot air flows out of the furnace and back into the
living area. When enough air in the living area has been heated,
the thermostat turns the furnace off automatically.
Picture B shows the flow of air inside and air outside the living
area. You can see that the air inside is not mixed with air outside
the living area. The furnace does not burn air that is within your
living area, and burned air or exhaust should not enter the living
area.

Page 20 12417-12416-2-0403
WALL THERMOSTAT
The wall thermostat is simply a switch that turns on when it is
cold and off when it is comfortable. When the thermostat turns on
it connects the small amount of electricity to the main gas valve
(part of combination valve in furnace), which then opens. Now
the pilot lights the gas and your furnace is on. When the living
area is warm enough, the wall thermostat switches off, the main
gas valve closes and your furnace turns off. The pilot remains lit
waiting to light the gas the next time the thermostat calls for heat
and turns the furnace on.
TEMPERATURE CONTROLS
Your Empire furnace has two safety switches (limits). When either
switch turns off, it turns your furnace off, even if the wall thermostat
is calling for heat. One of these switches can be moved to a LOW
HEAT or a FULL HEAT position. In FULL HEAT position the
register becomes very hot when the furnace heats the living area.
In LOW HEAT position the switch will turn the furnace off and on
again a few times before the living area is comfortable but it stops
the register from getting as hot as the FULL HEAT position.
DRAFT DIVERTER
The draft diverter is a collection box that is attached to the exhaust
end of your furnace. The draft diverter is a very important unit
and has two major functions:
1. It dilutes the flue products with cooler air.
2. It allows the furnace to burn properly during temporary
downdrafts.
Check the draft diverter and entire vent system each year for rust
damage and proper assembly.
COMBINATION VALVE
The combination valve in the furnace controls the gas. This valve
has a control handle with three positions marked: OFF, PILOT
and ON. When the handle is at OFF, all gas is cut off. When the
handle is at PILOT, the pilot can be lit. When the handle is at ON,
the gas will flow to the burner providing the pilot is lit and the
wall thermostat calls for heat.
USING YOUR FURNACE
BEFORE YOU TURN IT ON
Look down inside your furnace and make sure there isn't any
paper, packing material, or trash that could catch fire. Turn your
thermostat off or to its lowest temperature setting. See if the furnace
control handle (see C) is turned to OFF.
CAUTION
If the furnace control handle was not at OFF, turn it to OFF and
wait ten minutes before lighting a match or the pilot.
NOTE
You must press down on the furnace control handle to make it
turn to OFF.
You are now ready to light the pilot.
INSULATED VENT ENCLOSURE
Vented floor furnace installed with the vent going directly to the
outside and above the eaves can cause poor venting. The cold
vent pipe will have a delay in proper venting and cause spillage
of flue products at the draft diverter. The spillage of flue products
can result in pilot outage due to recirculation of flue products into
the main burner, also, condensation can occur in the vent pipe
which can cause an ice build-up or rusting of the draft diverter. To
prevent delayed venting as well as condensation of flue products
an insulated vent enclosure is recommended.
Use Type B vent pipe and maintain at least a one inch clearance
to combustibles.
Use metal thimble to protect vent pipe as it passes through
combustibles.
VENTING
Good venting is essential to good dependable heat. Venting removes
the exhaust that results when gas is burned inside your furnace. If
the exhaust is not vented away, the exhaust may gather under your
house and could seep into the house and be fatal. Venting is done
through a vent pipe (chimney) which, when correctly installed,
causes a draft (suction) at the end of the pipe that is connected to
the draft diverter. This suction carries away the exhaust from your
furnace. The vent pipe is connected to the draft diverter (see B)
which is mounted onto the furnace during installation. Refer to
the Installer and Serviceman's Manual for instructions on how to
properly vent your furnace. Remember, exhaust fumes, whether
they come from your furnace or your car, can be fatal.
B
FURNACE FEATURES
NO ELECTRICITY NEEDED
(Self Generating Pilot Control)
Your Empire furnace does not need electricity from your house;
it makes its own. When the pilot is lit, its heat is used to generate
a tiny amount of electricity (about 1/2 volt) which is all that is
needed by your furnace. This small amount of electricity keeps
the pilot valve (part of combination valve in furnace) open so the
pilot stays on. The small amount of electricity is also used with
the wall thermostat to turn on the furnace automatically when heat
is needed, and turn it off when it is comfortable.
