10,000 Btu per hour shall not be installed in a bedroom or
bathroom.
• Due to high temperatures, the appliance should be located
out of traffic and away from furniture and draperies.
• Children and adults should be alerted to the hazard of high
surface temperature and should stay away to avoid burns or
clothing ignition.
• Young children should be carefully supervised when they are
in the same room with the appliance.
• Do not place clothing or other flammable material on or near
the appliance.
• Due to high surface temperatures, keep children, clothing
and furniture away.
• WARNING: Do not use a blower insert, heat exchanger insert
or other accessory not approved for use with heater.
• 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 materials, etc. It is imperative that
control compartments, burners and circulating air passageways
of the appliance be kept clean.
• DO NOT use this room heater if any part has been under water.
Immediately call a qualified service technician to inspect the
room heater and to replace any part of the control system and
any gas control which has been under water.
• WARNING: ANY CHANGE TO THIS HEATER OR ITS
CONTROLS CAN BE DANGEROUS.
Any safety screen or guard removed for servicing an appliance
must be replaced prior to operating the heater.
• Keep appliance area clear and free from combustible materials,
gasoline and other flammable vapors and liquids.
• WARNING: Failure to keep the primary air opening(s) of the
burner(s) clean may result in sooting and property damage.
WARNING
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, 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
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.
Early signs of carbon monoxide poisoning resemble the flu,
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 influence 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 flow is not directed at
the burner.

SAFETY INFORMATION FOR USERS OF LP-GAS
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 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
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 firefighters
declare them to be safe.
NO ODOR DETECTED - ODOR FADE
Some people cannot smell well. Some people cannot smell the
odor of the chemical 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
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.
• 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.
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
• 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
Page 4
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 under
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 com-
pletely empty.

WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
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 must be used 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 dehumidifier 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
(an entire house).
PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR
Provisions for Adequate Combustion and Ventilation Air
This heater shall not be installed in a confined space or unusually
tight construction unless provisions are provided for adequate
combustion and ventilation air.
The National Fuel Gas Code, ANSI Z223.1 defines a confined space
as a space whose volume is less than 50 cubic feet per 1,000 Btu per
hour (4.8m3 per kw) of the aggregate input rating of all appliances
installed in that space and an unconfined space as a space whose
volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8m3
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 unconfined space.
The following example is for determining the volume of a typical
area in which the SR-18 may be located and for determining if
this area fits the definition of an unconfined space.
The maximum input of the SR-18 is 18,000 Btu per hour. Based
on the 50 cubic feet per 1,000 Btu per hour formula, the minimum
area that is an unconfined space for installation of the SR-18 is
900 cubic feet, 50 cubic feet x 18 = 900 cubic feet. To determine
the cubic feet of the area in which the SR-18 is to be installed,
measure the length, width and height of the area. Example: The
area measures 13 feet in length, 9 feet in width and 8 feet in
height, the area is 936 cubic feet. The SR-18 can be installed in
this unconfined space with no requirement to provide additional
combustion and ventilation air.
Warning: If the area in which the heater may be operated is smaller
than that defined as an unconfined 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.
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 defined 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
floors, between wall-ceiling joints, between wall panels, at
penetrations for plumbing, electrical, and gas lines, and at
other openings.
If the heater is installed in a building of unusually tight construction,
adequate air for combustion, ventilation and dilution of flue gases
shall be provided in accordance with ANSI Z223.1/NFPA54.

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 ad-
equate, contact your local authorized installer for installation or
relocation.
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!

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.
Figure 2
Method of Installing a Tee Fitting Sediment Trap (Figure 2)
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.
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 appliance main gas valve must be discon-
nected 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 sys-
tem by closing its equipment 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 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
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. (1.743kPa)
for the purpose of input adjustment to a maximum of 10.5" w.c.
(2.615kPa). Propane/LP gas will have a manifold pressure ap-
proximately 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).
A test gage connection is located downstream of the gas appliance
pressure regulator for measuring gas pressure. The connection is a
1/8 inch (3mm) N.P.T. plugged tapping.

SR-6 Main Burner Flame (Figure 15)
The main burner flame will have a red-orange glow over the sur-
face of the ceramic plaque. The red-orange glow on the surface of
the ceramic plaque will have a pattern in the shape of a number
1. The perimeter of the ceramic plaque [approximately the out-
side 1/4"(6mm)] will not glow. A few small, hairline cracks may
form over the surface of the ceramic plaques or at the edges of
the ceramic plaques where they have been cemented into position
on the burner assembly frame. These small, hairline cracks will
not affect the operation or performance of the ceramic plaques.
Only, when large cracks develop, with blue flames escaping from
the large cracks, should you contact your QUALIFIED SERVICE
PERSON.
SR-10, SR-18 and SR-30 Main Burner Flame (Figure 16)
The main burner flame will have a red-orange glow over the sur-
face of the ceramic plaques. A few small, hairline cracks may
form over the surface of the ceramic plaques or at the edges of the
ceramic plaques where they have been cemented into position on
the burner assembly frame. These small, hairline cracks will not
affect the operation or performance of the ceramic plaques. Only,
when large cracks develop, with blue flames escaping from the
large cracks, should you contact your QUALIFIED SERVICE
PERSON.
A red-orange haze that is visible on the ceramic plaques is accept-
able. A blue flame that rolls out at the top of the ceramic plaques
indicates an accumulation of dust, lint or spider webs inside the
casing assembly and main burner assembly. Use the following
procedure to inspect the casing assembly and main burner assem-
bly.
1. Turn OFF gas supply to the heater.
2. Turn OFF electric supply to the heater if optional blower is
installed in heater.
3. Remove lower louver from casing assembly ( 2 screws).
4. Remove reflector from casing assembly (2 screws).
5. Inspect interior of casing assembly for accumulation of dust,
lint or spider webs. If necessary, clean interior of casing
assembly with a vacuum cleaner or apply air pressure. Do
not damage any components within casing assembly when
you are cleaning.
6. Remove pilot bracket from main burner assembly (2
screws).
7. Pivot pilot bracket with attached pilot away from main burner
assembly (do not damage pilot tubing).
8. Inspect main burner orifice(s) through the rectangular
opening(s) in the venturi (throat) of the main burner(s). Dust,
lint and spider webs can accumulate on top of the main burn-
er orifice(s). If necessary, clean main burner orifice(s) with a
vacuum cleaner or apply air pressure. To thoroughly clean the
main burner orifice(s) proceed to Step 9.
9. Disconnect supply tubing from orifice holder(s).
10. Remove orifice holder from venturi of main burner assembly
(1 screw for each orifice holder).
11. Remove main burner orifice from orifice holder.

PILOT FLAME CHARACTERISTICS
The correct flame will be blue and will extend beyond the
thermocouple. The flame will surround the thermocouple just below
the tip. A slight yellow flame may occur where the pilot flame and
main burner flame meet.
Figure 17
Oxygen Depletion Sensor Pilot (Figure 16)
When the pilot has a large yellow tip flame, 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 our foreign materials such as dust, lint and
spider webs. Tighten nut B also by grasping nut A.
