than 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.

• 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/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.

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 im
prove 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 precau
tions which can protect both you and your family from an
accident. Read them carefully now, then review them point

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

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.

• 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 perform
ing 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.

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

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 (4.8m
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-30T may be located and for determining if
this area fits the definition of an unconfined space.

The input of the SR-30T is 30,000 Btu per hour. Based on the 50
cubic feet per 1,000 Btu per hour formula, the
is an unconfined space for installation of the SR-30T is 1,500 cubic
feet, 50 cubic feet x 30 = 1,500 cubic feet. To determine the cubic
feet of the area in which the SR-30T is to be installed, measure the
length, width and height of the area. Example: The area measures
16 feet in length, 12 feet in width and 8 feet in height, the area is
1,536 cubic feet. The SR-30T can be installed in this unconfined
space with no requirement to provide additional combustion and
ventilation air.

minimum area that

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
Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and
Ventilation, 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 SR-30T 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/

Dimensions Apply to SR-10T, SR-18T and SR-30T

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

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 flex
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 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.

MAIN BURNER FLAME CHARACTERISTICS

SR-10T, SR-18T and SR-30T Main Burner Flame (Figure12)
The main burner flame will have a red-orange glow over the surface
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 acceptable.
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 assembly.

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 burner 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.

12. Apply air pressure through main burner orifice and orifice
holder to remove dust, lint or spider webs.

13. Apply air pressure into ceramic plaque(s) to remove dust, lint
or spider webs.

14. As parts are being replaced in reverse order, check for gas
leaks at all gas connections before lower louver is replaced
onto casing assembly.

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 13

Oxygen Depletion Sensor Pilot (Figure 14)

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.

Figure 14

Never use needles, wires, or similar cylindrical objects to
clean the pilot to avoid damaging the calibrated ruby that
controls the gas flow.

.

THERMOSTAT OPERATION

To ignite main burner, turn gas control knob counterclockwise to
ward HI setting. To shut down main burner, turn gas control knob
clockwise toward LO setting.

The SR-10T has an input of 10,000 BTUH (2.9KW/H). The hy­draulic thermostat bulb is located at the casing assembly bottom.
When the hydraulic thermostat bulb senses the need for heat, the
unit cycles “ON” at a full input rate of 10,000 BTUH (2.9KW/H).
The unit remains at this full input rate until the hydraulic thermostat
bulb is “satisfied.” When the hydraulic thermostat bulb is “satisfied”
the burner will shut “OFF” with the pilot flame remaining “ON.”

The SR-18T has an input of 18,000 BTUH (5.3KW/H). The hy
draulic thermostat bulb is located at the casing assembly bottom.
When the hydraulic thermostat bulb senses the need for heat, the
unit cycles “ON” at a full input rate of 18,000 BTUH (5.3KW/H).
The unit remains at this full input rate until the hydraulic thermostat
bulb is “satisfied.” When the hydraulic thermostat bulb is “satisfied”
the burner will shut “OFF” with the pilot flame remaining “ON.”

Note: The burner does not modulate between “ON” and the pilot
flame. When the SR-18T is “ON,” all three ceramic plaques will
“glow.” There will never be a time when only one or two ceramic
plaques are “glowing.”

The SR-30T has an input of 30,000 BTUH (8.8KW/H). The hy
draulic thermostat bulb is located at the casing assembly bottom.
When the hydraulic thermostat bulb senses the need for heat, the
unit cycles “ON” at a full input rate of 30,000 BTUH (8.8KW/H).
The unit remains at this full input rate until the hydraulic thermostat
bulb is “satisfied.” When the hydraulic thermostat bulb is “satisfied”

the burner will shut “OFF” with the pilot flame remaining “ON.”

-

Note: The burner does not modulate between “ON” and the pilot
flame. When the SR-30T is “ON,” all five ceramic plaques will
“glow.” There will never be a time when only one or three ceramic
plaques are “glowing.”

The LO and HI setting has temperature range of approximately 55°F
(12.78°C) to 90°F (32.22°C), respectively. This is the temperature at
the hydraulic thermostat bulb not the room temperature. The owner
is advised to determine the particular heat setting that is desired for
comfort, as heating requirements are different for every owner.

­Attention: If the owner does not want the main burner to ignite

and turns the gas control knob to the LO setting, the main burner
will still ignite if the temperature at the hydraulic thermostat bulb
drops to 55°F (12.78°C).

If no heat is desired, turn the gas control knob to the PILOT posi
tion.

Piezo Pilot Ignitor Instructions

Depressing the ignitor button completely causes a spark to occur
at the pilot.

To light the pilot, it is important that the electrode be 1/8” (3mm)
from the pilot. The spark must occur at the point the pilot flame
hits the thermocouple.

On a new installation with air in the gas line, it is suggested that a
match be used. The match will light the pilot faster than the piezo
under this condition.

OPTIONAL BLOWER INSTALLATION INSTRUCTIONS (continued)

Wiring

The appliance, when installed, must be electrically grounded in accordance
with local codes or, in the absence of local codes, with the National Electri

cal Code, ANSI/NFPA 70, if an external electrical source is utilized

appliance is equipped with a three-prong [grounding] plug for your
protection against shock hazard and should be plugged directly into a
properly grounded three-prong receptacle. Do not cut or remove the
grounding prong from this plug. For an ungrounded receptacle, an adapter,

which has two prongs and a wire for grounding, can be purchased, plugged
into the ungrounded receptacle and its wire connected to the receptacle
mounting screw. With this wire completing the ground, the appliance cord
plug can be plugged into the adapter and be electrically grounded.

CAUTION: Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous operation.
Verify proper operation after servicing.
