Operating Guide

Ignition Process:
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.
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.
3. Release both buttons. Should the pilot go out, repeat steps 2 and 3.
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.
5. The heater will now operate normally. Room temperature will vary based on individual room size
and installation.
Shutdown Process:
To stop the heater, shut off the safety valve on the gas inlet line. Next, turn the Control Knob to the OFF
position.
INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often (see Figure 13 and Figure 14 for reference).
PILOT FLAME PATTERN
Two pilot burners with ODS function for NAT and LP gas respectively are installed on burners two sides
separately as shown in Figure. 13. The normal ODS pilot flame should have a correct pattern as shown in
Figure 14 in normal operation with exception during ignition stage.
