5. Turn control knob counterclockwise
to the PILOT position. Press in control
knob for five (5) seconds (see Figure 19).
Note:
You may be running this heater for
the first time after hooking up to gas sup-
ply. If so, the control knob may need to be
pressed in for 30 seconds or more. This will
allow air to bleed from the gas system.
• If control knob does not pop up when
released, contact a qualified service person
or gas supplier for repairs.
6. With control knob pressed in, push down
and release ignitor button (see Figure 19).
This will light pilot. The pilot is attached to
the front of burner. The pilot can be seen
through the glass panel. If needed, keep
pressing ignitor button until pilot lights.
Note:
If pilot does not stay lit, refer to
Troubleshooting, page 19. Also contact a
qualified service person or gas supplier for
repairs. Until repairs are made, light pilot
with match. To light pilot with match, see
Manual Lighting Procedure, page 16.
7. Keep control knob pressed in for 30 seconds
after lighting pilot. After 30 seconds, release
control knob.
• If control knob does not pop up when
released, contact a qualified service person
or gas supplier for repairs.
Note:
If pilot goes out, repeat steps 3
through 7. This heater has a safety interlock
system. Wait one (1) minute before lighting
pilot again.
8. Turn control knob counterclockwise
to desired heating level. The main burner
should light. Set control knob to any heat
level between 1 and 5.
CAUTION: Do not try to ad-
just heating levels by using the
equipment shutoff valve.

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. The thermostat adjusts the
amount of gas flow to the burner. This increases
or decreases the burner flame height. 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 1 and 5. Selecting the
5 setting will cause the burner to remain fully on
without modulating down in most cases.
Note:
Note:
The thermostat sensing bulb measures
the temperature of air near the heater cabinet.
This may not always agree with room tem-
perature (depending on housing construction,
installation location, room size, open air tem-
peratures, etc.). Frequent use of your heater will
let you determine your own comfort levels.
