GAS CONNECTION
All gas supply connections and any pipe joint compound must be resistant to the action of propane
gases. The machine connection is
3
/
4
" external thread. A manual valve (supplied) must be installed
in the gas supply line ahead of the appliance. Make sure piping is clean and free of obstructions, dirt,
or pipe joint compound. Recommended gas supply pressures are 7" W.C. (Water Column) for natural
gas and 11" W.C. for propane. The gas line must be capable of delivering gas to the oven without
excessive pressure drop at the rate specified on the rating plate.
The oven is equipped with a factory preset pressure regulator. Natural gas pressure regulators are
preset for 3.5" W.C. for both ovens and steam generators. Propane gas pressure regulators for 10 level
half and full and 20 level full ovens are preset for 10" W.C. for both ovens and steam generators.
Propane gas pressure regulators for 20 level half depth ovens are preset for 8" W.C. for oven burners
and 10" W.C. for steam generators.
Caster equipped ovens must be installed with a connector that complies with the
Standard for
Connectors for Movable Gas Appliances
, ANSI-Z21.69 (latest edition) [in Canada, CAN/CGA-6.16,
latest edition], and a quick-disconnect device that complies with the
Standard for Quick-Disconnect
Devices for Use with Gas Fuel
, ANSI-Z21.41 (latest edition) [in Canada, CAN 1-6.9, latest edition]. A
gas line strain relief must be provided to limit the movement of the oven without depending on the
connector and the quick-disconnect device or its associated piping to limit oven movement. Attach the
strain relief to the rear of the oven at the location provided. If it is necessary to disconnect the restraint
during service or maintenance, first turn off the gas supply. Reconnect the restraint before returning
the oven to its original installed location and turning the gas supply on.
WARNING
: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS.
USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
The convection burner and the steam generator burner are ignited automatically by electric igniters;
there are no pilot lights. See Start Up Procedure, page 7.
Keep the appliance area free and clear from all combustible substances. Do not obstruct the flow of
combustion and ventilation air. Make sure there is an adequate supply of air in the room to allow for
combustion at the burners and exhaust by the vent hood system.
