INSTALLATION Continued
Electrical Connection
Install oven in accordance with local electrical agencies and
code requirements. This equipment must be installed by a
competent factory trained, certified, licensed and/or authorized
service or installation person.
WARNING:
This appliance must be earthed. This appliance should be
connected to a potential equalization system. To facilitate this
a labeled equipotential bonding point is fitted to the rear of
the oven.
A wire diagram is affixed to the rear of the unit.
CAUTION:
DISCONNECT BOTH UNITS FROM
ELECTRICAL SUPPLY BEFORE SERVICING.
POWER FAILURE
In the event of a power failure, no attempt
should be made to operate this oven.
Ventilation & Air Supply
Proper ventilation is highly important for good operation. The
ideal method of venting a gas convection oven is through
the use of a properly designed canopy, which should extend
6" (150 mm), beyond all sides of the appliance and 6'6" (1950
mm) from the floor.
A strong exhaust fan will create a vacuum in the room. For an
exhaust system vent to work properly, exhaust and make-up
air must be balanced properly. For proper air balance contact
your local H.V.A.C. contractor.
All gas burners and pilots need sufficient air to operate and
large objects should not be placed in front of this oven, which
would obstruct the airflow through the front.

IMPORTANT
All gas burners and pilots need sufficient
air to operate and large objects should not
be placed in front of this oven, which would
obstruct the airflow through the front.
Objects should not be placed on main top rear
of oven while in use. This could obstruct the
venting system of the unit's flue products.
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 fittings 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 shutoff valve located on the redundant combination
gas valve. Activate control panel and set to desired
temperature. The pilot burner is ignited by direct spark,
main burners are then ignited by the pilot. Check all
fittings 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 off 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 five
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.
