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 written instructions provided with the heater for
information concerning combustion and ventilation
air. In the absence of instructions, refer to the National
Fuel Gas Code, ANSI Z223.1, Section 5.3 or applicable
local codes.
This heater is equipped with a PILOT LIGHT SAFETY SYS-
TEM designed to turn off the heater if not enough fresh air
is available.
DO NOT TAMPER WITH PILOT LIGHT SAFETY SYS-
TEM!
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.
Earlysignsofcarbonmonoxidepoisoningresembletheu,with
headache, dizziness and/or nausea. If you have these signs,
heater may not be working properly. Get fresh air at once! Have
heater serviced.
Some people — pregnant women, persons with heart or lung
disease,anemia,thoseundertheinuenceofalcohol,thoseat
high altitudes — are more affected by carbon monoxide than
others.
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
in the structure. When a fan is used to circulate air, it should be
locatedsothattheairowisnotdirectedattheburner.

IMPORTANT SAFETY INFORMATION

25783-5-1011Page 4
Some people cannot smell well. Some people cannot smell the
odorofthechemicalputintothegas.Youmustnd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 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.
Propane(LP-Gas)isaammablegaswhichcancauseres
and explosions. In its natural state, propane is odorless and
colorless. You may not know all the following 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.
• 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!

gases.
Well Head Gas Installations
Some natural gas utilities use "well head" gas. This may affect the
Btu output of the unit. Contact the gas company for the heating value.
Contact the manufacturer or your gas company before changing
spud/orice size.
WARNING
ANY CHANGE TO THIS HEATER OR ITS CONTROLS CAN
BE DANGEROUS.
Improper installation or use of the heater can cause seri-
ous injury or death from re, burns, explosion or carbon
monoxide poisoning.
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.
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,
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.
General Information
This series is design certied in accordance with American National
Standard Z21.11.2 by the Canadian Standards Association as an
Unvented Room Heater and should be installed according to these
INTRODUCTION

25783-5-1011Page 6
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.
This heater shall not be installed in a conned space or unusu-
ally tight construction unless provisions are provided for adequate
combustion and ventilation air.
A conned space is an area with volume less than 50 cubic feet per
1,000 Btuh of the combined input rates of all appliances drawing
combustion air from that space. Small areas such as equipment
rooms are conned spaces. Furnaces installed in a conned space
which supply heated air to areas outside the space must draw return
air from outside the space through tightly sealed return air ducts. A
conned space must have 2 openings into the space for combus-
tion air. One opening must be within 12 inches of the ceiling and
the other must be within 12 inches of the oor. The required sizing
of these openings is determined by whether inside or outside air is
used to support combustion, the method by which the air is brought
to the space (vertical or horizontal duct) and by the total input rate
of all appliances in the 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.
Unusually tight construction is dened as construction
where:
a. Walls and ceilings exposed to the outside atmosphere have
a continuous water vapor retarder with a rating of one perm
or less with openings gasketed or sealed, and
b. Weatherstripping has been added on openable windows and
doors, and
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.
If your home meets all of the three criteria above, you must provide
additional fresh air. See “VentilationAir From Outdoors,” page
7.
DeterminingifYouHaveaConnedorUnconnedSpace
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)

WARNING
Rework worksheet, adding the space of the adjoining
unconnedspace.Thecombinedspacesmusthaveenough
fresh air to supply all appliances in both spaces.
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 NFPA
54/ANSI Z223.1, Section 5.3 Air for Combustion and Ventilation 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.

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, Section 5.3 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inaconned
space.
VENTILATION AIR
Ventilation Air From Inside Building
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 1). You can also remove door into adjoining room
(see option 3, Figure 1). Each ventilation grill or opening shall have
a minimum free area of one square inch per 1,000 BTU/HR of the
total input rating of the gas equipment in the conned space.

25783-5-1011Page 8
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.
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.
Neveruseanexposedame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!
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 Z21.24Appliance Connectors of Corrugated Metal Tubing
and Fittings
— ANS Z21.45Assembled FlexibleAppliance 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 3
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
Millivolt Models 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).
Hydraulic Thermostat Models 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).
Millivolt Models 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).
Hydraulic Thermostat Models Propane gas 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).

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 right and left 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 19 to order loose material (rock wool).
Replacement Loose Material (Glowing Embers)
15998 Supplied Rock Wool
PE-20-1 Optional Platinum Bright Embers Kit
NOTICE: 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 pan 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.
NOTICE: all ames will be random by design, ame height will go
up and down.
Glowing embers (rock wool) can cover the pan 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.
This appliance must not be used with glass doors in the closed
position. This can lead to pilot outages and severe sooting outside
the replace.
