OPERATING HEATER
Continued
Note: Home owners generally prefer to op-
erate their heater with the chimney damper
closed. This will put all the heat into the room.
However, there may be times you will desire
the full flames of the HI heat setting but will
find the heat output excessive. You can open
the chimney damper (if you have one) fully or
partially to release some of the heat.
WARNING: Damper handle
will be hot if heater has been
running.
1. STOP! Read the safety information page 20.
2. Make sure equipment shutoff valve is
fully open.
3. Turn control knob clockwise
OFF position.
4. Wait five (5) minutes to clear out any gas.
Then smell for gas, including near the floor.
If you smell gas, STOP! Follow "B" in the
safety information on page 20. If you don't
smell gas, go to the next step.
5. Turn control knob counterclockwise
to the PILOT position. Press in control
knob for five (5) seconds (see Figure 27).
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.
6. With thermostat control knob pressed in,
press and release ignitor button. This will
light pilot. The pilot is attached to the front
burner. If needed, keep pressing ignitor
button until pilot lights.
Note: If pilot does not stay lit, 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 22.
7. Keep control knob pressed in for 30 seconds
after lighting pilot. After 30 seconds, release
control knob.
• If control knob does not pop out 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 minute for system to reset
before lighting pilot again.
