Ignition Procedure
- Ensure the gas supply valve to the heater is open.

- While holding the knob in, repeatedly press the IGNITOR button until the pilot flame ignites. You should see a small blue flame.
- Continue to hold the control knob in for approximately 30-60 seconds after the pilot ignites to allow the thermocouple to heat up.
- Release the control knob. The pilot flame should remain lit. If it extinguishes, repeat steps 3-5.
- Once the pilot is lit, push the control knob in slightly and turn it counter-clockwise to the desired heat setting: LOW or HIGH. The main burner will ignite.
