Gas Connection
This appliance is manufactured for use with the type of gas indicated on the data plate. Contact the
factory if the gas type does not match that which is on the data plate.
All gas connections must be in accordance with local codes and comply with the National Fuel Gas
Code ANSI Z223.1 latest edition.
An internal gas pressure regulator is located inside the control compartment.
Gas must be delivered to the appliance regulator at less than 1/2 pound of pressure and less than
1/2-inch water column pressure drop.
The internal regulator is preset at the factory, however, due to gas pressure variations from area
to area; it may be necessary to make minor adjustments to the regulator to provide the manifold
pressure indicated on the data plate. This should be 5 inches water column for natural gas and
10-inch water column for propane. A 1/8-inch NPT tap is provided on the main manifold for checking
regulator pressure. Access the main manifold by removing the bottom trim piece below the oven
doors.
When replacing the 1/8-inch plug in the main manifold a joint sealant that is resistant to the action of
liquid petroleum gas must be used.
The supply piping must be of sufficient size to provide 55,000 BTU/hr per oven. A 1/2-inch NPT
connection is provided at the rear of the oven directly behind the control compartment. Connect each
oven separately.
A gas shut off valve must be installed to the oven(s) and located in an accessible area.
This appliance and its individual shutoff 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 PSGI and the
appliance must be isolated from the gas supply piping system by closing its individual manual shutoff
valve during any pressure testing of the gas supply system at test pressures equal to or less than
1/2 PSIG.
Test for gas leaks. Use a commercial leak detector or a soap and water solution.
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 APPLIANCE MOVEMENT WITH OUT RELIANCE ON THE
GAS SUPPLY PIPING. SECURELY ATTACH THE TETHER TO THE
EYEBOLT PROVIDED AT THE REAR OF THE APPLIANCE.
