FOR YOUR SAFETY
READ BEFORE LIGHTING
WARNING: If you do not follow
these instructions exactly, a fire or
explosion may result causing
property damage, personal injury or
loss of life.
A. 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 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 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 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, don’t
try to repair it , call a qualified
service technician or gas supplier.
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
technician to inspect the
appliance and to replace any part of
the control system and any gas
control which has been under water.

THERMOSTAT
CONTROL OPERATION
The thermostatic control used on
these Models differs from standard
thermostats. Standard thermostats
simply turn on and off the burner.
The thermostat used on this heater
senses the room temperature. At
times the room may exceed the set
temperature. If so, the burner will shut
off. The burner will cycle back on
when room temperature drops below
the set temperature. The control
knob can be set to any heat
level between HI and LO.
NOTE
: The thermostat sensing bulb
measures the temperature of air near
the heater cabinet. This may not always agree with room temperature
(depending on housing construction,
installation location, room size, open
air temperatures, etc.)Frequent use of
your heater will let you determine
your own comfort levels.
MANUAL LIGHTING
PROCEDURE
1. Remove lower front panel (see
Figure 7 page 7).
2. Follow steps 1 through 5
under Lighting Instructions on
page 12.

pilot until pilot lights.
4. Keep control knob pressed in for

INSPECTING BURNER
Check pilot flame pattern and
burner flame pattern often.
PILOT FLAME PATTERN
Figure 22 shows a correct pilot
flame pattern. Figure 23 shows an
incorrect pilot flame pattern. The
incorrect pilot flame is not touching
thermocouple. This will cause the
thermocouple to cool. When the
thermocouple cools, the heater will
shut down. If pilot flame pattern is
incorrect, as shown in Figure 23.

CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before servicing.
CAUTION: Y ou 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 qualified service person. Heater may
need more frequent cleaning due to
excessive lint from carpeting, bedding
material, pet hair, etc.
CLEANING ODS/PILOT AND
BURNER
Use a vacuum cleaner,
pressurized air. or a small, soft
bristled brush to clean.
CLEANING BURNER
PILOT AIR INLET HOLE
We recommend that you clean the
unit every 2,500 hours of operation or
every three months. 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 PSl.
Your local computer store, hardware store, or home center may
carry compressed air in a can. 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.
1. Shut off the unit, including the
pilot. Allow the unit to cool for
at least thirty minutes.
2. Inspect burner, and pilot for dust
and dirt.
3. Blow air through the ports/slots
and holes in the burner.
Also, clean the pilot assembly. A
yellow tip on the pilot flame indicates dust and dirt in the pilot
assembly. There is a small pilot air
inlet hole about two inches from
where the pilot flame comes out of
the pilot assembly (see Figure 26).
With the unit off, lightly blow air
through the air inlet hole. You may
blow through a drinking straw if compressed air is not available.
Figure 26 - Pilot Inlet Air Hole
CLEANING HEA TER CABINET
Air Passageways
Use a vacuum cleaner or
pressurized air to clean.
Exterior
Use a soft cloth dampened with
a mild soap and water mixture.
Wipe the cabinet to remove dust.
