W ARN I NGS

Read this Installation and Owners Guide carefully and completely before attempting to install, operate or
service this heater. Improper use of this heater can result in serious bodily injury or death due to hazards of
fire, explosion, electrical shock or carbon monoxide poisoning. When used without fresh air, this heater may
give off CARBON MONOXIDE, an odorless, poisonous gas. CARBON MONOXIDE POISONING MAY
LEAD TO DEATH! Early signs of carbon monoxide poisoning resemble the flue with headache, dizziness
and/or nausea. If you have these signs, the heater may not be working properly. Get fresh air at once, and
have the heater serviced. Some people such as pregnant women, persons with heart or lung disease,
anemia, those under the influence of alcohol, and those at higher altitudes are more affected by carbon
monoxide than others. Retain this manual for future reference. It is your guide to many years of a proper
and safer operation of the heater.

1. Children and adults should be alerted to the

hazard of high surface temperatures and
should stay away to avoid burns or clothing
ignition.

2. Young children should be carefully supervised

when they are in the room with the heater.

3. Do not install this heater at altitudes above 5000
ft. because shutdown of the heater by the ODS
system may occur due to reduced oxygen levels
at these altitudes.

4. This appliance is

only for use with the type of

gas indicated on the nameplate. THIS

APPLIANCE IS NOT CONVERTI BLE FOR USE
WITH OTHER GASES. Please check the gas

type shown on the heater nameplate prior to
hooking the heater to the gas supply.

5. DO NOT install this heater in bedrooms or
bathrooms. The maximum input for use in
bathrooms is 6,000 Btu/hr and 10,000 Btu/hr
in bedrooms where not prohibited by local codes.

6. LPG containers (Propane cylinders) must not
be used or stored indoors.

7. DO NOT install this heater directly onto an LPG
container or propane cylinder without directions
from your propane company because high gas
pressure can damage this heater.

8. Always operate the heater at the OFF, P or one
of the three locked positions. Never operate
the heater at any setting between these locked
positions, as this may result in improper
combustion.

9. DO NOT locate this heater in high traffic areas
or in windy or drafty locations.

10. Keep the area near the heater free from
combustible materials, gasoline, and other
flammable vapors and liquids.

11. This appliance may be installed in an aftermarket*
manufactured (mobile) home, where not
prohibited by state or local codes. *Aftermarket:
Completion of sale, not for purpose of resale,
from the manufacturer.

12. DO NOT use this heater if any part has been
under water. Immediately call a qualified service
person to inspect the room heater and to replace
any part of the control system and any gas
control that has been under water.

13. This heater has a pilot light safety system that
turns off the heater if enough fresh air is not

available. The pilot light safety section on this
unit does not sense the presence of carbon
monoxide. It sense the depletion of the oxygen
supply used in the combustion
process.Combustion of gas with a depleted
oxygen supply is one source of carbon monoxide.

14. If this heater is installed in a room having a high
vertical dimension, a fan to circulate the air is
recommended to improve the comfort level in
the room. When a fan is used to circulate air,
it should be located so that the airflow is not
directed at the burner.

15. If installed in a garage, this heater must be wall
mounted only. The bottom of the heater must
be a minimum of 18" above the finished floor.

16. A vent-free gas heater will increase the amount
of humidity in the room in which it is installed.

This is an unvented gas fired heater. It uses
air (oxygen) from the room in which it is
installed. Provisions for adequate combustion
and ventilation air must be provided. Refer to
page 3 for a worksheet to determine whether
the proposed installation site is defined as
confined or unconfined.

17. A fresh air opening for combustion and ventilation
air must be provided in the room where the
heater is installed. The opening must have at
least one square inch of free air opening per
1,000 Btu/hr of gas consumption for the total
input rating of all gas equipment in the space.

18. This heater shall not be installed in a confined
space or unusually tight construction unless
provisions are provided for adequate combustion
and ventilation air.

19. 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 1 perm (6x10

-11

kg

per pa-sec-m

2

)or less with opeings gasketed

or sealed;

b) Weather stripping 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 other openings.

20. The National Fuel Gas Code defines a confined
space as a space whose volume is less than 50
ft

3

per 1,000 Btu/hr (4.8 m3/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 ft3 per 1,000
Btu/hr (4.8 m

3

/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 space.

21.

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/N FPA 54, Section

5.3 or applicable local codes.

The purpose of this worksheet is to help you determine if you are planning to install this heater in an “unconfined”
or a “confined” space. An “unconfined” space is one that is large enough to meet all the combustion and
ventilation air requirements of all the fuel burning appliances to be in operation in this space. No additional
air requirements are needed. A “confined” space is one that is not large enough to meet the combustion
and ventilation air requirements for all the fuel burning appliances in that space. As a result, additional air
is required in this space to meet the appliance needs. Check with your installer on ways to accomplish this,
or use a smaller Btu/hr input heater.

STEP 1: Determine the volume of the space in which the heater is to be installed. Include adjoining

rooms with doorless passageways. Example: 24' (long) x 16' (wide) x 8' (high) = 3072 ft

3

.

LENGTH x WIDTH x HEIGHT = ___________________________ Ft

3

STEP 2: Multiply the volume of the space (calculated in Step 1) by 20 BTU/hr to determine the

maximum BTU/hr that the space can support without additional combustion and ventilation
air provided.

Result from Step 1 ____________________ x 20 BTU/hr = ____________________ BTU/hr

STEP 3: Add the BTU/hr inputs of all fuel burning appliances in this space. NOTE: DO NOT include

Direct-Vent gas appliances because these have sealed combustion systems that draw
combustion air from outdoors. Examples of appliances to consider include: gas ranges,

gas water heaters, gas logs, kerosene heaters, etc.

Proposed Vent-Free Heater ______________________________ BTU/hr

Fuel Burning Appliance #1 ______________________________ BTU/hr

Fuel Burning Appliance #2 ______________________________ BTU/hr

TOTAL ______________________________ BTU/hr

STEP 4: Compare the results from Step 2 and Step 3.

If the result from Step 2 is greater than the result from Step 3, the area where the heater is to be installed
can be classified as an “unconfined space.” This means that the space is capable of handling the combustion
and ventilation air requirements of the existing fuel burning appliance(s) and the proposed heater.

If the result from Step 2 is less than the result from Step 3, the area where the heater is to be installed is
classified as a “confined space.” This means that either additional combustion and ventilation air must

be provided into this space (use the methods described in the National Fuel Gas Code, ANSI Z223.1­latest edition) or the size of the proposed heater must be reduced so that the above calculations show
the space to be an unconfined space.

Propane (LP-Gas) is a flammable gas that 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 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.

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, or

use your telephone. 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 safe.

¥ Use your neighbor's telephone 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.

NO ODOR DETECTED - ODOR FADE

SOME POINTS TO REMEMBER

Some people cannot smell well. Some people cannot
smell the 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. 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. Odor
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 above.

• 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
of 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 in the 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 absorption 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 sit too long before refilling. Cylinders and tanks

that 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 snif

f
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.

INSTALLATION TO GAS SUPPLY

1. The gas supply must comply with local codes, or in
their absence, the installation must be in accordance
with the American National Standard (National Fuel
Gas Code) NFPA 54, also known as ANSI Z223.1­latest edition, available from the ANSI Inc., 1434
Broadway, New York, New York 10018, or the National
Fire Protection Association, Batterymarch Park,
Quincy, Massachusetts 02269.

2.

WAR NI NG: When using LP gas, this heater
requires an external regulator (not supplied) located
between the heater and LP Supply Tank. This regulator
must be supplied by the installer to reduce incoming
LP Gas pressure to a maximum of 14 inches of water
column. Under no circumstances should this heater
ever be hooked directly to an LP supply tank.

IMPORTANT: The Pressure Regulator must be held
with a wrench when connecting gas piping and/or
fittings to the Pressure Regulator.

3. Use only new, black iron or rust resistant steel pipe.
Copper tubing may be acceptable in certain areas.

CHECK LOCAL CODES TO DETERMINE
ACCEPTABLE TYPES OF GAS PI PING.

4. The gas supply line shall be sized and installed to
provide a sufficient supply of gas to meet the minimum
demand of the heater without undue loss of pressure.

Typical Installation Supply Line

Up to 20,000 Btu/hr 3/8” or greater

Up to 30,000 Btu/hr 1/2” or greater

5. The sealant used on the threaded pipe joints of the
gas pipe must be the specific type resistant to the
action of Liquid Petroleum Gas. Apply sealant lightly
to male threads to ensure excess sealant does not
enter lines. Any excess sealant could be forced into
the pipe and result in clogged gas valves.

6. The supply system must include a manual shut-off
valve, a union in the line, and a plugged 1/8" NPT
tap. The tap should be accessible for test gauge
connections upstream of the gas supply connection
to heater.

7. Include a drip leg (trap) in the supply line. The
purpose of the drip leg is to prevent moisture and
contaminants in the gas supply from entering the
heater controls. The drip leg should be readily
accessible to permit cleaning or emptying. A drip
leg should not be located where the condensate is
likely to freeze. Failure to use a drip leg can result in
operational difficulties in the heater.

GAS SUPPLY CHECK

A union must be provided directly at the gas inlet to the
heater. A manual gas valve must be provided upstream
of the union. This will allow you to shut off the gas supply
to the heater if it is necessary to remove it for service
purposes.

The appliance and its appliance main 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. (3.45kPa).

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 _ psig.
(3.45kPa).

The connectors must be checked and cleaned before
assembling and then wrenched up tight for a gas tight
connection. Apply a soap and water solution to all joints
and watch for bubbles to check for gas leaks. NEVER

USE ANY OPE N FLAME TO CHECK FOR GAS LEAKS.

WARN ING: FAILURE TO KEEP TH E PRI MARY AIR
OPENING(S) OF THE BURNER(S) CLEAN MAY RESULT
IN SOOTING AND PROPERTY DAMAGE.

WAR NING: DO NOT ALLOW FANS TO BLOW DIRECTLY
INTO THE FIREPLACE. AVOID DRAFTS THAT ALTER
BURNER FLAME PATTERNS.

HEATER SERVICE

To service the heater, turn off the gas supply and
disconnect the gas piping at the union. Unscrew the two
screws located in the lower front part of the unit. By
sliding the panels upwards and toward the front, the
functional elements of the unit are uncovered.
Periodic cleaning of the unit is required. Dust the surface
of the unit and vacuum clean burner surfaces and the
control compartment.

BURNER

If this heater has an optional blower, disconnect the
electrical connection before servicing the heater (e.g.,
unplug the blower).
Keep the heater area clear and free from combustible
materials, gasoline and other flammable vapors and liquids.
If you need to replace the burner assembly, loosen screws
A and B, unscrew the tubing fittings C, tubing pilot E,
unscrew orifices D, and disconnect the assembly, see
Figure 4 (18,000 Btu/hr input model shown)

OXYGEN DE PLETION SENSOR (ODS) S ERVICING

Dust and dirt may effect heater performance.

This heater draws air into the bottom of it during normal
operation. In the process, dust and dirt will also be drawn
into the heater. The frequency of cleaning will depend
on how and where the heater is used. At a minimum,
you should clean the heater at least once a year, at the
beginning of the heating season.

If your pilot will not stay lit, try cleaning it. Use a can of
compressed air, such as is used to clean a computer, to
blow dust out of the pilot assembly. Sometimes just
blowing air back through the pilot will get rid of the dirt.

If that fails to solve the problem, remove the wire clip
that holds the metal strip onto the pilot assembly. Remove
the cover and blow any dust out. Reassemble and check
for proper operation.
If that fails, the pilot assembly should be removed and
air blown through the assembly and gas line as shown
in Figure 5. To prevent damage to this assembly, follow
the instructions below for disassembly and assembly of
the ODS for cleaning.

WARNING: Never use needles, wires, or similar
cylindrical objects to clean the pilot orifice. This will only
damage the calibrated ruby orifice (about the size of the
head of a pin) which controls the pilot gas flow.

Grab Nut A with an open-end wrench and loosen Nut B
from the pilot tubing. Blow air pressure through the
holes as indicated in Figure 5. This should blow out any
foreign materials. To reassemble, tighten Nut B by
grabbing Nut A with the open-end wrench.

NOTE:

When the heater is reassembled, always check for gas
leaks as outlined in the Gas Supply Section of these
instructions.

WARN ING: This vent-free

heater is approved for use only
with the type of gas indicated on
the heater nameplate. It is not
designed for use with other gases
and it is not convertible to use
with other gases. Contact our
Technical Service Department at
[phone] if you have any
problems.

4. Continue depressing the Control Knob for 15

seconds after the Pilot is lit before releasing. If the
knob does not pop up when released, STOP and

immediately call your service technician or gas
supplier.

5. The Pilot should remain lit, If the Pilot will not stay

lit after several tries, turn the gas control to “OFF”
and call your service technician or gas supplier.

6. The heat position can be selected by slightly

depressing the Control Knob and rotating it
counterclockwise (

) to Position 1, 2 or 3.

7. CAUTION: When the Control Knob has been rotated

to the heat setting, ensure that the Control Knob is
locked into that heat setting and cannot be rotated
without being depressed. If the Control Knob is in
a mid-position, incomplete combustion will take
place, causing a bad odor, and may produce gas
leakage or carbon monoxide.

If you do not follow these instructions exactly, a fire
or explosion may result causing property damage,
personal injury or loss of life.

A. This appliance has a pilot that must be normally

lighted by using the piezo igniter. When lighting
the pilot, follow these instructions exactly.

B. BE FORE LIGHTING smell all around the appliance

area for gas. Be sure to smell next to the floor
because some gas is heavier than air and will settle
on the floor.

WHAT TO DO IF YOU SMELL GAS:

• Do not try to light any appliance.

• Do not touch any electric switch; do not use any
telephone in your building.

• Immediately call your gas supplier from a
neighbor's telephone. Follow the gas supplier's
instructions.

• If you cannot reach your gas supplier, call the
fire department.

C. Use only your hand to push in or turn the gas control

knob. Never use tools. If the knob will not push in
or turn by hand, do not try to repair it. Call a qualified
service person. Force or attempted repair may result
in a fire or explosion.

D. Do not use this appliance if any part has been under

water. Immediately call a qualified service person to
inspect the appliance and to replace any part of the
control system that has been under water.

LIGHTING INSTRUCTIONS
