INSTALLATION
Install sediment trap in supply line as shown
(See Fig. 20). Place sediment trap where it is
within reach for cleaning. Place sediment trap
where trapped matter is not likely to freeze. A
sediment trap traps moisture and contaminants.
This keeps them from going into heater controls.
If sediment trap is not installed or is installed
wrong, heater may not run properly.
Fig. 20 - Gas Connection
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all
leaks immediately.
WARNING: Never use an open ame to check for a leak. Apply a 50/50 mixture of liquid soap and
water to all joints. If bubbles form, there may be a leak. Correct all leaks immediately.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG ( 3.5kPa )
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 ½ psi (3.5 kPa).
Pressure Testing Gas Supply Equal To or less than
1/2 PSIG ( 3.5kPa )
The appliance must be isolated from the gas supply piping system by closing its equipment shut-off
valve during any pressure testing of the gas supply piping system at test pressures equal to or less
than ½ psi (3.5 kPa).
Leak Testing Heater Gas Internal Connections
1. Open equipment shutoff valve (See Fig. 21).
2. Make sure control knob of heater is in the OFF position.
3. Open gas supply tank valve (LP systems).
4. Check all joints from equipment shutoff valve to control
valve. Apply 50/50 mixture of liquid soap and water
to gas joints. If bubbles form, there may be a leak.
5. Light heater (see Operation, page 18). Check all other
internal joints for leaks.
6. Turn off heater (see "To Turn Off Gas to Appliance,"
page 19).

FOR YOUR SAFETY READ BEFORE LIGHTING
WARNING: If you do not follow these instructions exactly, a re or explosion may result
causing property damage, personal injury or loss of life.
A. This appliance has a pilot which must be lighted using the Ignitor. When lighting the pilot,
follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the oor
because some gas is heavier than air and will settle on the oor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the re 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, don't try to repair it, call a qualied service technician. Forced or
attempted repair may result in a re or explosion.
D. Do not use this appliance if any part has been under water. Immediately call a qualied service
technician to inspect the appliance and to replace any part of the control system and any gas
control, which has been under water.

THERMOSTATIC CONTROL OPERATION (SELECT MODELS)
The control knob can be set to any comfort level between
"HIGH" (5) and "LOW"(1) (See Fig. 25).The thermostat used on
this heater senses the room temperature. At times the room may
exceed the set temperature. When this begins to happen, the
burner will begin to modulate the BtuH down until the unit meets
the desired heat setting and shuts off. When the room
temperature drops below the desired heat setting, the burner will
cycle back on. The unit may start at a lower BtuH rate if the room
is still warm.
MANUAL CONTROL OPERATION
Manual valves remain burning at the desired setting until
manually turned to OFF " "(See Fig. 25).

OPERATION
INSPECTING BURNERS
Check pilot ame pattern daily when in use and at least yearly by a qualied service agency.
PILOT FLAME PATTERN
Fig. 26 shows a correct pilot ame pattern. Fig. 27 shows an incorrect pilot ame pattern. The
incorrect pilot ame is not touching the thermocouple. This will cause the thermocouple to cool,
which shuts the heater off. If pilot ame pattern is incorrect:
• turn heater off (see “To Turn Off Gas to Appliance” on page 19)
• see Troubleshooting pages 23 through 26.

NOTE: Ambient ame burners produce both a blue and yellow ame. An excessively high yellow
colored ame may be caused by airborne dust, dander, pet hair, etc. Additionally, an excess
amount of Mercaptane in the fuel can result in an orange or yellow colored ame.
The upper third of ame
may be bright yellow when
operated on propane.
When this heater is set for use on propane gas, the upper one third of the ame may be bright yellow.
When this heater is set for use on natural gas, a slight yellow tipping of the ame may occur.

NOTE: Before servicing you will need to remove the front panel of the
heater. There are 4 Philips head screws, 2 on the left side and 2 on the
right, securing the front panel to the heater (See Fig. 30). Always allow
the unit to cool for at least thirty minutes before attempting to remove the
front panel.
WARNING: Turn off heater, unplug electrical cord and let cool
before servicing.
CAUTION: You must keep control areas, burner, and circulating air
passageways of heater clean. Inspect these areas of heater before each
use. Have heater inspected yearly by a qualied service person. Heater
may need more frequent cleaning due to excessive
lint from carpeting, bedding material, pet hair, etc.
WARNING: Failure to keep the primary air opening(s) of the
burner(s) clean may result in sooting and propery damage.
CLEANING ODS/PILOT AND BURNER
Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean burner ports, orice
and primary burner. Look into burner opening and ensure that it is clean.
CLEANING BURNER PILOT AIR INLET HOLE
We recommend that you clean the unit every three months or after 2,500 hours of operation. We
also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt.
To clean these parts we recommend using compressed air no greater than 30 PSI. You can use a
vacuum cleaner in the blow position. If using compressed air in a can, please follow the directions
on the can. If you don't follow directions on the can, you could damage the pilot assembly.
CAUTION: Never use a wire, needle, or similar object to clean ODS/pilot. This can damage ODS/ pilot unit.
1. Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes.
2. Remove 4 screws - 2 screws on each side of the front panel.
3. Pull front panel forward.
4. Blow air through the ports/slots and holes in the burner. Also clean the pilot assembly. A yellow tip
on the pilot ame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole
about two inches from where the pilot ame comes out of the pilot assembly (see Fig. 26 & 27
on page 20). With the unit off, lightly blow air through the air inlet hole. You may blow through a
drinking straw if air is not available.
5. Replace front panel when completed, using the screws removed.
CLEANING GLASS
Use mild soap and water. Avoid using abrasive cleaners which can scratch the glass. The tempered
glass installed on this product contains a “Low E” coating on the interior surface. If the glass is
removed, you must ensure the “Low E” coated side is installed on the interior side, facing the burner
assembly.
CLEANING CABINET AIR PASSAGEWAYS
Use a vacuum cleaner or pressurized air to clean.
CLEANING FAN (Select Models)
Carefully use a vacuum cleaner or compressed air to keep fan compartment and blades free of dust
and debris.
NOTE: The fan motor is pre-lubricated for extended bearing life and requires no further lubrication.
CLEANING EXTERIOR
Use a soft cloth dampened with a mild soap and water mixture.
Wipe the cabinet to remove dust.
