STARTUP AND CHECKOUT
Perform Gas Leak Test
WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE, SEVERE
INJURY, OR DEATH
Check for gas leaks with soap and water solution any
time work is done on a gas system.
Gas Leak Test
1. Ensure that the gas supply is turned on at the appliance
service valve.
2. Paint the pipe connections upstream of the pilot burner
with rich soap and water solution. Bubbles indicate a
gas leak.
3. If a leak is detected, tighten the pipe connections.
4. Stand clear of the main burner while lighting to prevent
injury caused from hidden leaks, which can cause
flashback in the appliance vestibule. Light the main
burner.
5. With the main burner in operation, paint the pipe joints
(including the adapters) and gas control inlet and outlet
with rich soap and water solution.
6. If another leak is detected, tighten the adapter screws,
joints, and pipe connections.
7. Replace the part if the leak cannot be stopped.
Adjust Pilot Flame
The pilot flame should envelop 3/8 to 1/2 in. (10 to 13 mm) of
the thermocouple or thermopile tip. See Fig. 24 To adjust the
pilot flame:
1. Remove the pilot adjustment cover screw from the gas
control.
2. Turn the inner pilot adjustment screw clockwise to
decrease or counterclockwise to increase the pilot
flame.
3. Replace the pilot adjustment cover screw and tighten
firmly after completing adjustment to ensure proper
operation.
