safety precautions which can protect both you and your
family from an accident. Read them carefully now, then
review them point 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 reading the following information,
you feel you still need more information, please contact
your gas supplier.
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!
• 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 reghters declare them to be safe.
• Use your neighbor's phone and call a trained LP-Gas
service person and the re 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 reghters 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.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot

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 under-
ground leak, the movement of the gas through soil can lter
the odorant. 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.
SOME POINTS TO REMEMBER
•        Your local
LP-Gas Dealer can give you a "Scratch and Sniff" pam-
phlet. Use it to nd 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 qualied, do not light pilot lights, perform
service, or make adjustments to appliances on the LP-Gas
system. If you are qualied, 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 lled
and allowed to set too long before relling. 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. Aperiodic 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 under no vapor pressure), turn the tank valve off im-
mediately. If the container valve is left on, the container
may draw in some air through openings such as pilot light
orices. 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 relled before it is
completely empty.

750 Millivolt System
When you ignite the pilot, the thermocouple produces millivolts
(electrical current) which energizes the magnet in the gas valve.
After 30 seconds to 1 minute time period you can release the gas
control knob and the pilot will stay ON. Allow your pilot ame to
operate an additional one (1) to two (2) minutes before you turn the
gas control knob from the PILOT position to the ON position. This
time period allows the millivolts (electrical energy) to build-up to a
sufcient level allowing the gas control to operate properly.
Important
All correspondence should refer to complete Model Number, Serial
Number and type of gas.
Moisture Resistance
This outdoor replace will shed moderate amounts of water, but is
not waterproof. Water and condensing water vapor may enter the
chase under certain conditions.
The replace will not perform as an exterior wall. Moisture penetration
must be considered for construction that places the replace in
structure walls or on moisture sensitive surfaces.
When installed on exterior walls: Empire Comfort Systems
recommends the replace chase be constructed outside the
structure's weather envelope. Where the platform meets the wall, use
a ashing detail similar to that required for attached decks. Chase
platforms, including hearths should slope away from the structure
at 1/4 in per foot. The replace can be shimmed level.
When installed on surfaces where water may collect or cause
damage: Empire Comfort Systems recommends a slope of 1/8 in
to 1/4 in per foot towards the drain port suggested. The replace
can be shimmed level.
Hearths should slope away from the front of the replace and chase
at 1/8 in to 1/4 in per foot. Metal safety strips must be on top of
any combustible hearth materials used for moisture management.
When purchasing a rebox or replace we recommend you also
buy a weather cover or glass door accessory to protect the unit
from moisture.
Never install a burner where moisture cannot drain off easily. We
recommend a weather barrier - such as a cover or bifold glass
doors - to protect the burner from moisture.
Screened Porch Installation
The replace may be installed safely and is design certied by CSA
to be installed in a screen porch with the following guidelines.
Minimum Porch Area 96 sq. feet (9 sq m)
Minimum Ceiling Height 92" (234 cm)
Minimum of two (2) walls must be screened
Minimum top of screen height, side walls 6'6" (198 cm)
Minimum screen area 64 sq. feet (6 sq m)

High Altitude Installation
When installing this unit at an elevation above 2000 feet (in the
United States) it may be necessary to decrease the input rating by
changing the existing burner orice to a smaller size. Generally,
input should be reduced 4 percent for each 1000 feet above sea
level. However, if the heating value of the gas has been reduced,
this general rule may not apply. Check with local gas utility for proper
orice size identication.
For Canadian high altitude applications, this appliance is suitable for
installation at elevations between 0 feet (0m) and 4,500 (1,370m)
without change.
When installing this unit at an elevation above 4500 feet (1,370m)
(in Canada), check with local authorities.
Consult your local gas utility for assistance in determining the proper
orice for location.

Check all local codes for requirements, especially for the size and
type of gas supply line required.
NOTICE: Never use plastic pipe. Check to conrm whether your
local codes allow copper tubing or galvanized.
NOTICE: Since some municipalities have additional local codes, it is
always best to consult your local authority and installation code.
Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
In the state of Massachusetts the gas cock must be a T handle type.
A manual main gas cock should be located in the vicinity of the unit.
Where none exists, or where its size or location is not adequate,
contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liqueed 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.

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!
A gas valve and ground joint union should be installed in the gas
line upstream of the gas control to aid in servicing. It is required by
the National Fuel Gas Code that a drip line be installed near the gas
inlet. This should consist of a vertical length of pipe tee connected
into the gas line that is capped on the bottom in which condensation
and foreign particles may collect.
The use of the following gas connectors is recommended:
— ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing
and Fittings
— ANS Z21.45 Assembled Flexible Appliance Connectors of Other
Than All-Metal Construction
The above connectors may be used if acceptable by the authority
having jurisdiction. The state of Massachusetts requires that a exible
appliance connector cannot exceed three feet in length.
Figure 2
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3.175mm)
N.P.T. plugged tapping, accessible for test gauge connection, must
be placed immediately upstream of the gas supply connection
to the appliance.
2. The appliance andits individual shutoffvalve must bedisconnected
from the gas supply piping system during any pressure testing of
that system at test pressures in excess of 1/2 psig (3.5 kPa).
3. The appliance must be isolated from the gas supply piping system
by closing its individual manual shutoff 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 procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve, it will
result in a hazardous condition.
Checking Manifold Pressure
Natural gas models will have a manifold pressure of approximately
3.5" w.c. (.871kPa) at the pressure regulator outlet with the inlet
pressure to the pressure regulator from a minimum of 5.0" w.c.
(1.120kPa) for the purpose of input adjustment to a maximum of
10.5" w.c. (2.615kPa).
Propane gas models will have a manifold pressure approximately
10.0" w.c. (2.49kPa) at the pressure regulator outlet with the inlet
pressure to the pressure regulator from a minimum of 11.0" w.c.
(2.739kPa) for the purpose of input adjustment to a maximum of
13.0" w.c. (3.237kPa).
ONR and ONI
NOTICE: The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to provide a 1/8"
test point up stream of the control.
