GAS CONNECTION
Attach gas plumbing to the 3/8” NPTM fitting located on the right hand rear corner of the
oven.
WARNING
CONVECTION OVENS INSTALLED WITH CASTERS MUST HAVE THE FOLLOWING:
A CONNECTOR THAT COMPLIES WITH THE STANDARD FOR CONNECTORS FOR
MOVABLE GAS APPLIANCES ANSI Z21.69 LATEST EDITION, A QUICK DISCONNECT
THAT COMPLIES WITH THE STANDARD FOR QUICK DISCONNECT DEVICES FOR USE
WITH GAS FUEL, ANSI Z21.141 LATEST EDITION, A TETHER OR OTHER MEANS TO
LIMIT APPLIANCES MOVEMENT WITH OUT RELIANCE ON THE GAS SUPPLY PIPING.
SECURELY ATTACHED THE TETHER TO THE EYEBOLT PROVIDED AT THE REAR OF
THE APPLIANCE.
BEFORE LIGHTING, USE A SOAP AND WATER SOLUTION TO TEST ALL JOINTS FOR
GAS LEAKS.
PRESSURE TESTING THE GAS SUPPLY LINE
During pressure testing note the following:
1. The oven and its individual manual shut-off valve must be disconnected from the gas supply piping
system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 kPa).
Turn OFF
main gas shut-off valve or main gas supply line.
2. The oven must be isolated from the gas supply piping system by closing its individual manual shut-
off valve during any pressure testing of the gas supply piping system at test pressures equal to or
less than 1/2 psig (3.45 kPa).
3. If incoming pressure is over 12" water column, a separate regulator for the oven must be installed
before the gas supply to the oven.
To prevent damage to the control valve regulator during the initial turn-on of
gas, it is very important to open the manual shut-off valve very slowly. After the
initial gas turn-on, the manual shut-off valve must remain open except during
pressure testing as outlined in the above steps or when necessary during service
maintenance.
NOTE: The supplied regulator is evaluated for a maximum gas supply pressure of
14" water column (34.5 mBar). The recommended maximum gas supply pressure
is 12" water column (29.9 mBar).
PRESSURE TESTING THE GAS CONTROL VALVE
Determine the outlet pressure is 4” W.C. by applying power to the valve
and energizing both valve solenoids. Use the outlet pressure tap con-
nection on the underside of the valve body to monitor the outlet
pressure. The outlet pressure tap is a bleed hole with a cast
spigot, sealed with a threaded brass needle screw.
To monitor the outlet pressure, turn the screw in a
counterclockwise direction one or two turns
and fit a 9 mm diameter flexible tube
over the cast spigot. After mak-
ing all valve adjustments and
obtaining the desired outlet
pressure, remove the flexible
tube. Tighten the needle screw
by turning it clockwise with a
slotted screwdriver until hand
tight, sealing the bleed hole
.
