5. Operating Instructions
5.1 Initial Startup and Purging
- After gas connections are complete, slowly turn on the main gas supply valve.
- It may take several attempts to light the pilot light during the initial startup as air is purged from the gas lines.
5.2 Lighting the Pilot and Main Burner
This heater uses an electronic spark ignition system.
- Ensure the gas supply is on.
- Turn the control knob to the 'PILOT' position.
- Press and hold the control knob in. While holding, repeatedly press the igniter button until the pilot flame lights.
- Continue to hold the control knob in for approximately 30-60 seconds after the pilot lights to allow the thermocouple to heat up. Release the knob slowly. If the pilot goes out, repeat steps 2-4.
- Once the pilot is stable, turn the control knob to the desired heat setting (e.g., '1' to '5' or 'HI'). The main burner will ignite.
