WATER VAPOR: A BY-PRODUCT OF
UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion.
An unvented room heater produces approximate-
ly one (1) ounce (30ml) of water for every 1,000
BTU's (.3KW's) of gas input per hour. Refer to
page 8.
WARNING: If not installed, operated and main-
tained in accordance with the manufacturer's in-
structions, this product could expose you to sub-
stances in fuel or from fuel combustion which can
cause death or serious illness.

When used without adequate combustion and ventilation air,
heater may give off CARBON MONOXIDE, an odorless,
poisonous gas.
Do not install heater until all necessary provisions are
made for combustion and ventilation air. Consult the writ-
ten instructions provided with the heater for information
concerning combustion and ventilation air. In the absence
of instructions, referto the National Fuel Gas Code,ANSI
Z223.1/NFPA 54, Air for Combustion and Ventilation, or
applicable local codes.
This heater is equipped with a PILOT LIGHT SAFETY
SYSTEM designed to turn off the heater if not enough fresh
air is available.
DO NOT TAMPER WITH PILOT LIGHT SAFETY
SYSTEM!
If heater shuts off, do not relight until you provide fresh air.
If heater keeps shutting off, have it serviced. Keep burner and
control compartment clean.
CARBON MONOXIDE POISONING MAY LEAD TO
DEATH.

The pilot light safety system senses the depletion of oxygen at its
location. If this heater is installed in a structure having a high
vertical dimension, the possibility exists that the oxygen supply
at the higher levels will be less than that at the heater. In this type
of application, a fan to circulate the structure air will minimize
this effect. The use of this fan will also improve the comfort level

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 lter 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.

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 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. 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 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.
• 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.
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!

Operation
This unvented replace requires no outside venting. This unvented
replace is designed for vent-free operation with ue damper
closed. State and local codes in some areas prohibit the use of
unvented replace.
(A)VFD26F(M,P)3, Millivolt controls
The valve regulator controls the burner pressure which should be
checked at the pressure test point. Turn captured screw counter
clockwise 2 or 3 turns and then place tubing to pressure gauge over
test point (Use test point “A” closest to control knob). After taking
pressure reading, be sure and turn captured screw clockwise rmly
to re-seal. Do not over torque. Check for gas leaks.
Millivolt System, (A)VFD26F(M,P)3
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 current) to build-up to
a sufcient level allowing the gas control to operate properly.
WARNING: This appliance is equipped for (natural gas or propane)
gas. Field conversion is not permitted.

Water vapor is a by-product of gas combustion. An unvented room
heater produces approximately one (1) ounce (30ml) of water for
every 1,000 BTU's (.3KW's) of gas input per hour. .
Unvented room heaters are recommended as supplemental heat (a
room) rather than a primary heat source (an entire house). In most
supplemental heat applications, the water vapor does not create a
problem. In most applications, the water vapor enhances the low
humidity atmosphere experienced during cold weather.
The following steps will help insure that water vapor does not
become a problem.
1. Be sure the heater is sized properly for the application, including
ample combustion air and circulation air.
2. If high humidity is experienced, a dehumidier may be used to
help lower the water vapor content of the air.
3. Do not use an unvented room heater as the primary heat
source.

3. Add the BTU/Hr of all fuel burning appliances in the space.
Vent-free heater BTU/Hr
Gas water heater BTU/Hr
Gas furnace BTU/Hr
Vented gas heater BTU/Hr
Gas replace logs BTU/Hr
Other gas appliances* + BTU/Hr
Total = BTU/Hr
Example: Vented gas heater 20,000 BTU/Hr
Vent-free heater + 18,000 BTU/Hr
Total = 38,000 BTU/Hr
*Do not include direct-vent gas appliances. Direct vent draws
combustion air from the outdoors and vents to the outdoors.
4. Compare the maximum BTU/Hr the space can support with the
actual amount of BTU/Hr used.
BTU/Hr (maximum the space can support)
BTU/Hr (actual amount of BTU/Hr used)
Example:
25,600 BTU/Hr (maximum the space can support)
38,000 BTU/Hr (actual amount of BTU/Hr used)
Warning: If the area in which the heater may be operated is smaller
than that dened as an unconned space or if the building is of
unusually tight construction, provide adequate combustion and
ventilation air by one of the methods described in the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and
Ventilation, or applicable local codes.
The space in the above example is a conned space because the
actual BTU/Hr used is more than the maximum BTU/HR the space
can support. You must provide additional fresh air. Your options
are as follows:
A. Rework worksheet, adding the space of an adjoining room. If
the extra space provides an unconned space, remove door to
adjoining room or add ventilation grills between rooms. See
Ventilation Air From Inside Building.
B. Vent room directly to the outdoors. See Ventilation Air From
Outdoors.
C. Install a lower BTU/Hr heater, if lower BTU/Hr size makes
room unconned.
If the actual BTU/Hr used is less than the maximum BTU/Hr the
space can support, the space is an unconned space. You will need
no additional fresh air ventilation.
WARNING: You must provide additional ventilation air

This heater shall not be installed in a conned space or unusually
tight construction unless provisions are provided for adequate
combustion and ventilation air.
The National Fuel Gas Code denes a conned space as a space
whose volume is less than 50 cubic feet per 1,000 Btu per hour
(4.8m3per kw) of the aggregate input rating of all appliances
installed in that space and an unconned space as a space whose
volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3
per kw) of the aggregate input rating of all appliances installed in
that space. Rooms communicating directly with the space in which
the appliances are installed, through openings not furnished with
doors, are considered a part of the unconned space.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough
fresh air for combustion and ventilation. However, in buildings of
unusually tight construction, you must provide additional fresh
air.

c. Caulking or sealants are applied to areas such as joints
around window and door frames, between sole plates and
oors, between wall-ceiling joints, between wall panels, at
penetrations for plumbing, electrical, and gas lines, and at
other openings.

Use this worksheet to determine if you have a conned or unconned
space.
Space: Includes the room in which you will install heater plus any
adjoining rooms with doorless passageways or ventilation grills
between the rooms.
1. Determine the volume of the space (length x width x height).
Length x Width x Height = cu. ft. (volume of
space)
Example: Space size 16 ft. (length) x 10 ft. (width) x 8 ft. (ceiling
height) = 1,280 cu. ft. (volume of space)
If additional ventilation to adjoining room is supplied with grills
or openings, add the volume of these rooms to the total volume
of the space.
2. Divide the space volume by 50 cubic feet to determine the
maximum BTU/Hr the space can support.
(volume of space) ÷ 50 cu. ft. = (maximum
BTU/Hr the space can support)
Example: 1,280 cu. ft. (volume of space) ÷ 50 cu. ft. = 25.6 or
25,600 (maximum BTU/Hr the space can support)

This fresh air would come from an adjoining unconned space.
When ventilating to an adjoining unconned space, you must
provide two permanent openings: one within 12" of the ceiling
and one within 12" of the oor on the wall connecting the two
spaces (see options 1 and 2, Figure 5). You can also remove door
into adjoining room (see option 3, Figure 5). Each ventilation grill

Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must
provide two permanent openings: one within 12" of the ceiling
and one with 12" of the oor. Connect these items directly to the
outdoors or spaces open to the outdoors. These spaces include attics
and crawl spaces. In most cases for direct communication with the
outdoors or direct communication through a vertical duct a free
area opening of one square inch per 4,000 BTU/HR of heater input
rating for each grill. If a horizontal duct is used, a grill free area or
duct opening shall have a free area opening of one square inch per
2,000 BTU/HR for each grill. Follow the National Fuel Code, ANSI
Z223.1/NFPA54, Air for Combustion and Ventilation, or applicable
local codes, for required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet or outlet air
into attic if attic has a thermostat-controlled power vent. Heated
air entering the attic will activate the power vent.

Installing a New Main Gas Cock
Each appliance should have its own manual gas cock.
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.

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 Tub-
ing 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 ex-
ible appliance connector cannot exceed three feet in length.
Pressure Testing of the Gas Supply System
1. To check the inlet pressure to the gas valve, a 1/8" (3mm) 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 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 (3.5 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).
Figure 7
Attention! If one of the above 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
(A)VFD26F(M,P)3 Natural gas will have a manifold pressure of
approximately 3.5" w.c. (.871kPa) for maximum input or 1.7" w.c.
(.423kPa) for minimum input 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. (2.614kPa).
(A)VFD26F(M,P)2 Natural gas will have a manifold pressure of
approximately 6.0" w.c. (1.49kPa) at the pressure regulator outlet
with the inlet pressure to the pressure regulator from a minimum
of 7.0" w.c. (1.74kPa) for the purpose of input adjustment to a
maximum of 10.5" w.c. (2.615kPa).
(A)VFD26F(M,P)3 Propane gas will have a manifold pressure
approximately 10.0"w.c. (2.49kPa) for maximum input
or 6.3"w.c. (1.568kPa) for minimum input 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).
(A)VFD26F(M,P)2 Propane gas will have a manifold pressure

Replacement Loose Material

Platinum Bright Embers PE-20-1
23466-4-0509Page 16
Provided with the log set is a small bag of glowing embers (rock
wool) to be placed between logs on the at metal surface of the
burner.
Placement of the embers (rock wool) is very individual and light
coverage of the areas indicated will provide your best effects. We
recommend separation of the rock wool by hand and make your
coverage as light and uffy as possible.
Place just enough embers (rock wool) on the burner to obtain the
glow and a gold yellow ame.
Do not place rock wool over large ports in rear portion of burner.
A thin layer of rock wool should be placed under open space
between the front and middle logs.
Rock wool should not be placed in the area of the pilot
assembly.
Replacement of loose material (glowing embers) must be purchased
from Empire Comfort Systems, Inc. Application of excess loose
material (glowing embers) may adversely affect performance of
the heater.
WARNING: All previously applied loose material must be removed
prior to reapplication.
Refer to Parts List, Page 26 to order loose material (rock wool).
Note: A single layer of embers is to be used when applying Platinum
Bright Embers (alone or in combination with production embers)
to the burner.
Flames from the pilot (rear right back side of the burner) as well
as the main ame should be visually checked as the log set is
installed.
In normal operation at full rate after 10 to 15 minutes, the ame
appearance should be sets of yellow ames.
NOTE: All ames will be random by design, ame height will
go up and down.
Glowing embers (rock wool) can cover the burner in between the
front and middle logs, but very little is necessary to cover this
area. Excess ember material causes the yellow ame to become
orange and stringy. Apply just enough to obtain slow glow and a
gold, yellow ame.
Avoid any drafts that alter burner ame patterns. Do not allow fans
to blow directly into replace. Do not place a blower inside the
burner area of the rebox. Ceiling fans may create drafts that alter
ame patterns. Sooting and improper burning will result.
During manufacturing, fabricating and shipping, various
components of this appliance are treated with certain oils, lms or
bonding agents. These chemicals are not harmful, but may produce
annoying smoke and smells as they are burned off during the initial
operation of the appliance, possibly causing headaches or eye or
lung irritation. This is a normal and temporary occurrence.
The initial break-in operation should last 2-3 hours with the burner
at the highest setting. Provide maximum ventilation by opening
windows or doors to allow odors to dissipate. Any odors remaining
after this initial break-in will be slight and will disappear with
continued use.

Figures 15 and 18 show a correct pilot ame pattern. The correct
ame will be blue and will extend beyond the thermocouple. The
ame will surround the thermocouple just below the tip. A slight
yellow ame may occur where the pilot ame and main burner ame
meet. Figures 16 and 19 show an incorrect pilot ame pattern. The
incorrect pilot ame is not touching the thermocouple. This will
cause the thermocouple to cool. When the thermocouple cools, the
heater will shut down.

Cleaning and Maintenance/Pilot
Oxygen Depletion Sensor Pilot
When the pilot has a large yellow tip ame, clean the Oxygen
Depletion Sensor as follows:
1. Clean the ODS pilot by loosening nut B from the pilot tubing.
When this procedure is required, grasp nut A with an open end
wrench.
2. Blow air pressure through the holes indicated by the arrows.
This will blow out foreign materials such as dust, lint and spider
webs. Tighten nut B also by grasping nut A.
Warning:
Never use needles, wires, or similar cylindrical objects to
clean the pilot to avoid damaging the calibrated ruby that
