service valve located on the redundant combination gas
valve . Should any gas leaks be detected turn OFF the main
gas valve, correct the problem and begin the test again .
Remove the blanking plug from the manifold test spigot and
connect a pressure test gauge .
Open the manual gas valve located behind the redundant
combination gas valve .
Activate the control panel and set the oven to the desired
temperature . The burner will now ignite .
During installation there will be air in the gas line . This air will
have to bleed off before ignition can occur . Wait five minutes
after each attempt to bleed the air from the lines .
Turn on all appliances supplied by the same gas line and
verify that the manifold pressure is 4 .5” WC for natural gas or
10” WC for propane gas .
GAS MODEL TESTING & LIGHTING INSTRUCTIONS
After the correct pressure has been verified, turn off the oven
and remove the pressure gauge from the manifold pressure
test spigot . Re-install the blanking plug .
Check all fittings again . Correct any leaks and begin the test
again .
Replace all control panels, service panels and covers before
operation .
All electronic ignition systems are supplied with a redundant
gas valve . Therefore, the oven is not supplied with an external
pressure regulator .
To Conserve Energy:
Do not waste energy by leaving the controls at high
temperature settings during idle periods . Lower settings will
keep the oven warm and ready for the next use period .
