odor of the chemical stench 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. Some-
times other odors in the area mask the gas odor. People may not

about smelling a gas odor can make it easier to smell.
The odorant in LP-gas is colorless, and it can fade under

Propane (LP-Gas) is a flammable gas which can cause fires
and explosions. In its natural state, propane is odorless and
colorless.Youmay not knowallthefollowingsafety precau-
tions which can protect both you and your family from an
accident. Read them carefully now, then review them point
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-Gasmaystratifyinaclosedarea,andtheodorintensitycould
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.

service, or make adjustments to appliances on the LP-Gas
system.Ifyouarequalified,consciouslythinkabouttheodor

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.

SAFETY INFORMATION FOR USERS OF LP-GAS
• Do not operate electric switches, light matches, use your
phone. Do not do anything that could ignite the gas.
• Geteveryoneoutofthebuilding,vehicle,trailer,orarea.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.
• Useyourneighbor'sphoneandcalla trainedLP-Gasservice

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.
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!

each opening shall have a free area of not less than one square inch
(6.5cm2) per 1,000 BTU's (.3KW) of total input. The draft hood must
be in the same atmospheric pressure zone as the combustion air inlet
to the appliance.
Gas Supply
Check all local codes for requirements, especially for the size and
type of gas supply line required. On Natural gas lines less than 15'
(4.5m) long, use 1/2" (13mm) pipe; on longer runs, use 3/4" (19mm)
iron pipe or equal. On LP gas lines please consult LP gas supplier.
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!
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
NationalFuelGas Code thatadrip linebeinstalled near thegasinlet.
Thisshouldconsistofa verticallengthofpipe,tee connectedintothe
gas line, that is capped on the bottom in which condensation and
foreign particles may collect.
Method of Installing A Tee Fitting Sediment Trap
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 the test gauge connection, must be
placed immediately upstream of the gas supply connection to the
appliance.
2. Theappliance,anditsindividualshutoffvalve,mustbedisconnected

Locating and Venting the Room Heater
Clearances: When facing the front of the room heater the minimum
clearances to combustible construction (material) are the following:
Left side 6 inches (152mm). Right side 6 inches (152mm).
Recommed 18 inches ((457mm) on left side for servicing.
Do not install in alcove or closet. No horizontal projection above
heater permitted within 55 inches (140cm).
Ceiling55inches (140cm). Draft hoodtorear wall 2inches(51mm).
Openinfronttoprovideservice,access,andclearancetoconstruction.
Venting
1. Flue pipe must be as large as the flue collar on the draft diverter.
2. Maintain an upward slope of at least 1/4 inch (6mm) per foot of
horizontal run.
3. Run flue pipe as directly as possible with a minimum of elbows.
4. Flue pipe should extend through the wall of a chimney to be
flush with inner wall.
5. Flue pipe must be adequately supported by metal strips.
6. Single wall vent pipe may be attached directly to the draft hood
of the room heater when a clearance of 2 1/2 inches (64mm) is
maintainedbetweenthesinglewallventpipeandthecombustible
wallofthe roominwhich the roomheater is located.Usedouble
wall vent pipe for 1 inch (25mm) clearance to combustibles.
7. For flue pipe running through walls and roof, use B-1 [1 inch
(25mm) clearance to combustibles] vent pipe.
8. Chimneys should extend at least 2 feet (.6m) above the roof and
above any object or nearby building within 10 feet (3m).
9. Open tees should not be used in the flue pipe.
10. Appliance must not be connected to a chimney flue that is
servicing a separate solid-fuel burning appliance.
For proper venting, do not attach a 90°elbow directly to draft
diverter. If possible, attach 2 feet (.6m) of straight vent pipe before
an elbow is used. Use of 45°elbows is recommended.
Uninsulated single-wall metal pipe shall not be used outdoors in
cold climates for venting gas utilization equipment.
Ventilation and Combustion Air
Room heaters shall be installed in a location in which the facilities
for ventilation permit satisfactory combustion of gas and proper
ventingundernormalconditions.Inbuildingsofconventionalframe,
brick or stone construction without tight storm windows and doors,
infiltration is normally adequate to provide for combustion and draft
hood dilution.
Where appliances are installed in a confined space within a building,
thebuildingbeingofunusuallytightconstruction,airforcombustion
andventilationmust beobtaineddirectly fromoutdoorsor fromsuch
spaces that freely communicate with the outdoors. Under these
conditions, the confined space shall be provided with two permanent
openings, one near the top of the enclosure and one near the bottom;

3. Theappliancemustbeisolatedfromthegassupplypipingsystemby
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 (3.5kPa).
Attention! If one of the above procedures results in pressures in excess
of 1/2 psig (14" w.c.) (3.5kPa) on the appliance gas valve, it will result
in a hazardous condition.
Checking Manifold Pressure
Both Propane and Natural gas valves have a built-in pressure regulator
that has a sealed adjustment. Natural gas models will have a manifold
pressure approximately 4.0" w.c. (.996kPa) at the valve outlet with the
inlet pressure to the valve from a minimum of 5.0" w.c. (1.245kPa) for
the purpose of input adjustment to a maximum of 10.5" w.c. (2.61kPa)
Propane gas models will have a manifold pressure approximately 10.0"

to a maximum of 13.0" w.c. (3.237kPa).
A 1/8" (3mm) N.P.T. plugged tapping, accessible for test gauge
connection is located on the outlet side of the gas control.
Liner and Insulated Liner
Whenyouinstallaventedroomheaterintoamasonrychimneyyoumust
follow these steps.
1. The chimney must be lined and sized properly. Most masonry
chimneys are over sized and absorb too much heat to be considered
apropervent. If youhaveany doubts linethechimneywith theright
size liner. If it's unlined you must line it.
2. Useaninsulatedlinerwhenthechimneyisontheoutside,threesides
exposedtotheweather,andthereisnoclaylinerinthechimney.The
insulation will help keep the flue gases warmer.
Insulated Vent Enclosure
Vented room heaters installed with the vent going directly to the outside
and above the eaves can cause poor venting. The cold pipe will have a

is equipped with a vent safety shutoff system.
Warning:
Operation of this heater, when not connected to a properly
installedandmaintainedventingsystem ortamperingwiththe
ventsafety shutoffsystem,canresultincarbonmonoxide(CO)
poisoning and possible death.
This appliance needs fresh air for safe operation and must be installed
so there are provisions for adequate combustion and ventilation air.
This room heater is equipped with a vent safety switch. The vent safety
switch will cause gas flow to the pilot to "shut off" due to improper
venting or a blocked flue.
If the vent safety switch continues to "shut off" the gas flow to the pilot
a qualified service person must be contacted to inspect for improper
venting, blockage in the vent pipe or the vent safety switch for being
defective.
DRAFT DIVERTER CAN BE EITHER A VERTICAL VENT OR HORIZONTAL VENT
Reversible Vertical or Horizontal Draft Diverter
This room heater has a reversible draft diverter. The draft diverter is
installed in the vertical position at the factory. Please use the following
steps to change the draft diverter from the vertical position to the
horizontal position.

Proper Pilot Flame
Thecorrect flamewillbealmosthorizontal,blueand willextend past
the thermocouple 1/4" (6mm). The flame will surround the
thermocouple just below the tip.
OnPropane (LP-gas)slight yellowmight occurwhere thepilot flame
and the burner flame meet.
Natural gas pilots require adjusting when the inlet pressure is above
5" w.c. (1.25kPa). Remove pilot adjustment cover. Turn adjustment
screw clockwise to reduce flame.
Propane (LP-gas) will not require adjusting.
Proper Main Burner Flame
There will be a short blue inner flame with a larger, lighter blue
secondary flame. The burner flame may have yellow tips when hot.
Dust in the combustion air will produce an orange or red flame. Do
not mistake the orange or red flame for an improper yellow flame.
The flame will be proper if the factory-set pressure and orifice are
used. After use, cleaning may be required for the proper flame.
Cleaning Pilot Burner
After use, cleaning of the pilot burner may be required for the proper
flame.Thepilotorificecanbecleanedwithhighpressureairorbyplacing
under running water. Pilot orifice must be dry before replacement. Use a
pipe cleaner to clean inside the pilot after the pilot orifice has been
removed.
Removing Pilot Orifice
1. Disconnect the pilot supply line at the pilot burner.
2. Remove pilot orifice from pilot burner. It may be necessary to tap on
pilot burner in order to remove the pilot orifice.
Cleaning Main Burner
Remove the burner and apply water pressure inside the throat of the
burner and down into the ports; follow with air pressure.
Removing Main Burner
1. Remove casing front.
2. Disconnect pilot bracket from the burner.
3. Remove brass nut from burner.
4. Disconnect burner from chamber leg flange.
5. Remove burner from bottom of combustion chamber.
Cleaning Combustion Chamber
Aqualifiedservicemanshouldremovethechamberandapplyairpressure
to the inside in order to clear all passageways.
Thermostat Operation
To turn on burner, rotate dial knob toward setting number 9. To shut
down burner, rotate dial knob toward setting number 1.
Thedialnumbers 1to 9correspondto 58°to90°F(14°to 32°C).This
is the temperature at the bulb thermostat 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: When the dial knob is turned below number 1, to the
white indicator mark and the bulb temperature drops to 55°F (13°C),
the thermostat will call for heat and the main burner will ignite.
If no heat is desired, turn the gas control knob to the PILOT position.
Primary Air Adjustment
1. A primary air adjustment bolt is located on left, front of burner
throat. The bolt can be screwed into burner throat to REDUCE
primary air or unscrewed from burner throat to INCREASE
primary air.
To reduce yellow flame on main burner unscrew bolt from burner
throat. Also, refer to Step 2.
To reduce resonation (whistling) noise or extinction (popping)
noise screw bolt into burner throat.
2. An air shutter bracket is attached to top of burner throat. The air
shutter bracket lays flat across top of burner throat.
If yellow flames can not be removed from main burner by using
primary air adjustment bolt, the air shutter bracket can be pivoted
upward to allow additional primary air to enter burner throat.
On Propane gas, if a whistling noise (resonation) occurs screw
the air adjustment bolt into the burner throat to eliminate the
whistling noise (resonation).

Wiring
The appliance, when installed, must be electrically grounded in
accordancewithlocalcodesor, in theabsenceoflocalcodes,with
the National Electrical Code, ANSI/NFPA 70 or Canadian
Electrical Code, CSA C22.1, if an external electrical source is
utilized. This 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
prongfrom thisplug. For an ungrounded receptacle, an adapter,
whichhastwoprongsand awireforgrounding,canbepurchased,
plugged into the ungrounded receptacle and its wire connected to
the receptacle mounting screws. With this wire completing the
ground, the appliance cord plug can be plugged into the adapter
and be electrically grounded. A 7/8" (22mm) hole is provided in
the junction box for use with a conduit connector if local codes
require this type of protection.
