STARTUP AND CHECKOUT
On-Off Switch
The on-off switch settings are as follows:
• OFF: Prevents main gas flow through the control.
• 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 electronic on-off
switch 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. This can damage the control. Do not use
an excessive amount of soap and water solution
to perform the gas leak test. Apply only to pipe
thread areas.
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 bushings) and the control inlet and
outlet with rich soap and water solution.
5.
If another leak is detected, turn the gas control to
off, tighten the joints and pipe connections.
6.
Replace the part if a leak cannot be stopped.
Turn On System
Push the on-off switch to the ON position.
Turn On Main Burner
Follow appliance manufacturer instructions or turn
thermostat up to call for heat.
