Pilot Gas and Lighting Procedure
•
Turn the gas control knob counterclockwise to the PILOT position, push the gas control knob IN and HOLD in
position.
This will open the pilot valve and allows gas to flow to the pilot burner.
•
Light the pilot burner while holding the gas control knob in until a strong pilot flame is present. (Approximately 60 seconds)
•
Release the gas control knob. The gas control knob will hold in and engages the valve power unit.
•
Turn the gas control knob counter clockwise to the ON position, the main burner valve will open and the main
burner will ignite.
NOTE: Gas controls with model number AF-1000 for vented to decrease the pilot flame turn the pilot adjustment screw
clockwise. To increase the pilot flame turn the pilot adjustment counter clockwise.
NOTE: Gas controls with model number AF-1100 for vent free applications have NO pilot adjustment, per test standard.
Shut off Procedure
1. To shut OFF the system, turn the gas control knob clockwise to the OFF position. This action will close the main
gas valve and disengages the safety pilot valve. However the power unit must drop out before the lighting sequence can
begin again. This may take as much as 3 minutes.
2. To relight the pilot, follow the steps in the Pilot Gas and Lighting Procedure section.
Pilot Burner Connections
This gas control uses a pilot burner with a thermocouple, the connections are as follows:
1. Connect the pilot tubing fitting into the gas control connection and tighten. (Use caution on brass connectors) Note: Figure
#7 & #8
2. Connect thermocouple into power unit at the back of the gas control. Note: Figure #8
NOTE: A standard thermocouple or quick drop out thermocouple with 11/32-32 UNS threads and Ventfree ODS thermocouple
with 8mm x 1.0 thread can be used. Note: Figure #8
