STARTUP AND CHECKOUT

WARNING

Fire or Explosion Hazard.

Can cause property damage, severe injury or death.

1.Do not force the gas control knob on the appliance. Use only your hand to turn the gas control knob. Never use any tools.

2.If the knob does not operate by hand, the control should be replaced by a qualified service technician.

Gas Control Knob Settings

Gas control knob settings are as follows:

•ON: Permits gas to flow into the control body. Under control of the thermostat and direct ignition module, gas can flow to the main burners.

NOTE: Controls are shipped with the gas control knob in the ON position.

Perform Gas Leak Test

WARNING

Fire or Explosion Hazard.

Can cause property damage, severe injury or death.

Perform Gas Leak Test every time work is done on a gas system.

IMPORTANT

Do not spray soap and water solution on the gas control. Do not use an excessive amount of soap and water solution to perform the gas leak test. These can damage the control.

Gas Leak Test

1.Paint pipe connections upstream of the gas control with rich soap and water solution. Bubbles indicate a gas leak.

2.If a leak is detected, tighten the pipe connections.

3.Light the main burner. Stand clear of the main burner while lighting to prevent injury caused from hidden leaks that could cause flashback in the appliance vestibule.

4.With the main burner in operation, paint the pipe joints (including adapters) and the control inlet and outlet with rich soap and water solution.

5.If another leak is detected, tighten the adapter screws, joints, and pipe connections.

6.Replace the part if a leak cannot be stopped.

Turn On System

Rotate the gas control knob counterclockwise to ON.

Turn On Main Burner

Follow appliance manufacturer instructions or turn thermostat up to call for heat.
