1.15 LEAK TESTING
If a pressure leak test above 1/2 psi is to be
performed on the building supply gas piping, the
shut-off gas valve and oven inlet gas supply line
must be disconnected from the building supply
piping before conducting the pressure test. Failure
to do so may result in damage to the manual gas
valve, gas components in the oven, or both.
If any gas leak tests are to be conducted at pressures
equal to or below 1/2 psi, the manual gas shut-off
valve upstream of the oven must be turned off before
conducting the tests.
Leak testing of the internal oven piping system was
conducted before shipping the oven from the factory.
If additional testing is needed, it should only be
conducted at normal gas supply pressures.
testing is performed using combustible gas in the
piping, the leak checking should be done with a soap
solution (bubble checking).

1.16 FUEL INTERLOCK SYSTEM

Local codes may require the fuel supply to the oven be interlocked to the ventilation hood. If that is the case,
a separate, electrically operated gas valve must be installed in the gas line. Valve selection is at the discretion
of the installer, however, the valve must be recognized by the authority which has jurisdiction.
1.17 GAS EXHAUST
The oven is not designed for direct connection to a chimney vent
system or for direct connection to a horizontal exhaust system.
The oven must be installed under a ventilation hood listed to
A N S I / U L 7 0 5 ( l a t e s t e d i t i o n ) , a n d t h e i n s t a l l a t i o n m u s t b e

Commercial Cooking Operations.
The oven is supplied with a flue diverter which must be installed
on the oven prior to installation.
toward the front of this manual.
Oven operators should be instructed with regard to the
hazards of placing any material on top of the oven that
would obstruct the flow of flue products out the
opening of the flue diverter. Operators should also
be instructed with regard to the hazards of hot flue
gases and that any material or items placed on top of, or in front
of the flue defector could be damaged or cause a fire hazard.

The use of an electronic combustible gas leak detector
is helpful, however, this type of detector can be
oversensitive. Electronic detectors may indicate false
leaks from other sources which would not be detected
when checking with a liquid solution to verify a
no-hazard gas connection.
NEVER CHECK FOR LEAKS
USING AN OPEN FLAME.
When starting the oven after initial installation, the
gas lines must be free of air. It may take up to 30
minutes to eliminate all air from the lines. If, after
this time there is no pilot, call for factory assistance.
