Testing & Lighting Instructions
1. Turn on main gas valve. Remove the lower front cover
and the service panel above the control panel. Drop the
control panel and leak test all ttings and connections
upstream from the service valve located on the redundant
combination gas valve. Should any gas leaks be detected,
turn OFF main gas valve, correct the problem and retest.
2. Open shuto valve located on the redundant combination
gas valve. Activate control panel and set to desired
temperature. The pilot and burner is now ignited by direct
spark. Check all ttings again and correct any leaks and
recheck.
Replace all service panels and covers before operation.
NOTE: All electronic ignition systems are supplied with a
redundant gas valve. Therefore, the unit is not supplied with
an external pressure regulator.
NOTE: During installation there will be air in the gas line, this
air will have to bleed o before ignition can be established.
The electronic ignition system has a ninety second lock-out
as a safety device on all units. Therefore, several attempts
may be required before pilot ignition is established, wait ve
minutes after each attempt.
FOR YOUR SAFETY: KEEP YOUR APPLIANCE AREA FREE FROM
COMBUSTIBLES.
TO CONSERVE ENERGY:
Do not waste energy by leaving controls at high temperature
settings during idle periods. Lower settings will keep
oven warm and ready for next use period. Master 400
Series controls have an auto setback feature that is user
programmable to help with these applications.
