Adjustable temperature settings determine the length of time that
the heater will operate at maximum BTU to achieve desired temperature.
All 5 ceramic plaques will operate simultaneously, regardless of Control
Knob setting.
During first seasonal use, gas smell is expected to be more noticeable than in
standard operation.
Operation Notes:
To stop the heater, shut off the safety valve on the gas inlet line. Next, turn
the heater's Control Knob to the OFF position.
Shutdown Process:
5. The heater will now operate normally. You should adjust the Control
Knob to your desired heat setting. Room temperature will vary based
on individual room size and installation.
4. Once the pilot flame is stable, turn the Control Knob counterclockwise
from the Pilot setting to the desired number setting. This should be
done slowly in one motion, without stopping between positions. Knob
will only turn if you have a stable pilot light.
3. Release both buttons. Should the pilot go out, repeat steps 2 and 3.
2. With the Control Knob set to Pilot, push down on both the Igniter
Button and the Control Knob simultaneously until ignition can be
heard. Continue to hold down both buttons for at least 15 seconds,
until the pilot is touching the thermocouple and is noticeably heated.
1. During the first seasonal operation, set the Control Knob to Pilot, then
hold down on the Control Knob for 3-5 minutes. This allows the air in
the manifests to clear completely. During normal operation, you will
only need to hold the Control Knob down on Pilot for about 5 seconds.
Ignition Process:
Follow these steps to ensure that your heater
is running the right way, every time.
