5. Operating Instructions
Your Comfort Glow Direct Vent Heater is designed for user-friendly operation with matchless piezo ignition and adjustable thermostat control.
- Initial Startup (Lighting the Pilot):
- Ensure the gas supply is open.
- Turn the control knob to the "PILOT" position.
- Press and hold the control knob in. While holding, repeatedly press the piezo ignitor button until the pilot light ignites.
- 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 the process.
- Turning On the Main Burner: Once the pilot light is stable, turn the control knob from "PILOT" to your desired temperature setting. The main burner will ignite.
- Adjusting Temperature: Use the adjustable thermostat control knob to set the desired room temperature. The heater will cycle on and off to maintain this setting.
- Turning Off the Heater: To turn off the main burner, turn the control knob to the "PILOT" position. To completely shut off the heater (including the pilot light), turn the control knob to the "OFF" position and close the main gas supply valve.
