To light the pilot on a Williams Wall Furnace model #5009622, follow these steps:

1. Smell for Gas – Before lighting, check for the smell of gas. If you detect gas, do not proceed. Turn off the gas supply and call your gas supplier or fire department.

2. Locate the Gas Control Valve – The furnace is equipped with a Williams gas control valve (P295000A or P295001A).

3. Turn the Control Knob – Use only your hand to push in or turn the gas control knob. Do not use tools.

4. Manually Light the Pilot – This model has a pilot that must be lit by hand:
- Push in the control knob and hold it.
- Light the pilot using a match or the manual spark ignitor (if equipped).
- Continue holding the knob for about 30 seconds to allow the thermocouple to heat up.
- Release the knob and check if the pilot remains lit.

5. Adjust the Pilot Flame – The flame should surround the generator tip by 1/4 to 3/8 inches. Adjust if needed by turning the pilot adjusting screw.

6. Set the Thermostat – Turn the thermostat to the highest setting and ensure the main burner ignites smoothly. Then, set it to the desired temperature.

If the pilot does not stay lit, repeat the process. If it still fails, contact a qualified technician.
