Operating Guide

Ignition Process:
1. Turn the Thermostat Knob to the widest area, representing full heat. Next, turn the Control Knob to
the Pilot setting.
2. 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.
3. While continuing to keep the Control Knob pushed in, also push down on the Igniter Button
thoroughly 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.
4. Release both buttons. Should the pilot go out, repeat steps 3 and 4.
5. Once the pilot flame is stable, slightly push the Control Knob down while turning from the Pilot
setting to the Burner position . This should be done slowly in one motion, without stopping
between positions. Knob will only turn if you have a stable pilot light.
6. The heater will now operate normally. You should adjust the Thermostat Knob to your desired heat
setting. 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 heater's Control Knob to
the OFF position.
Note: Adjustable temperature settings determine the length of time that the heater will operate at
maximum BTU to achieve desired temperature, not the actual flame height.
Overheating Sensor: This heater is equipped with an overheating sensor. The sensor will detect and
automatically completely shut down the unit operation, including the gas flow, should the sensor
temperature reach 212 degrees Fahrenheit.
INSPECTING BURNER
Check pilot flame pattern and burner flame pattern often.
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 Fig. 10. The normal ODS pilot flame should have a correct pattern as shown in
Fig. 11 in normal operation with exception during ignition stage.
WARNING: If yellow tipping occurs, your heater could produce increased levels of carbon monoxide. If
burner flame pattern shows yellow tipping, follow instructions in the Care and Maintenance section.
Notice: Do not confuse orange flames with yellow tipping. Dirt or other fine particles enter the heater and
burn causing brief patches of orange flame.
