bathroom.
• An unvented room heater having an input rating of more
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
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
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 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
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 in LP-Gas also are subject to oxidation. This fading can
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 reenter 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.
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 reinstalled old tanks, if they are filled and allowed
Page 4 16009-1-0504
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 completely empty.

16009-1-0504 Page 5
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 (4.8m3 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-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 minimum area that
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.
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 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/NFPA54.

GAS SUPPLY
The gas line can be routed either through the floor or wall. The gas
line opening should be made at this time. Location of the opening
will be determined by the position of floor joists and the valve and
union used for servicing.

Figure 1
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 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!
16009-1-0504 Page 7
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
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.
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
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 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 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).
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-10T CLEARANCES
When facing the front of the appliance the following minimum
clearances to combustible construction must be maintained.
