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 APPLIANCE MOVEMENT WITH OUT RELIANCE ON THE GAS
SUPPLY PIPING. SECURELY ATTACH THE TETHER TO THE EYEBOLT
PROVIDED AT THE REAR OF THE APPLIANCE.
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, adjust 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 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.
Flu Installation
A flu extension must be installed on the lower oven of a stacked set.
The extension attaches to the flu opening of the lower oven and directs the flu
products into the flu opening of the upper oven.
This extension must be installed.
The ovens may now be set into position. Be careful if sliding the ovens, they
are not designed to slide over cracks or obstructions in the floor.
