GAS CONNECTION
NOTE: The gas supply (service) line must be the same size or greater than the inlet line of the appliance. Imperial
ranges and ovens use a ¾” NPT inlet. Sealant on all pipe joints must be resistive to LP gas.
MANUAL SHUT-OFF VALVE
This installer –supplied valve must be installed in the gas service line ahead of the appliance and regulator
in the gas stream and in a position where it can be reached quickly in the event of an emergency.
PRESSURE REGULATOR
All commercial cooking equipment must have a pressure regulator on the incoming service line for safe
and efficient operation, since service pressure may fluctuate with local demand. The manual shut-off valve is
normally supplied by the installer, however, a pressure regulator is packed inside each Imperial range.
Failure to install a pressure regulator will void the equipment warranty
The regulators supplied for Imperial ranges, have ¾” inlet/outlet openings and are adjusted at the factory
for 5” WC (natural gas) or 10” WC (propane) depending on the customer’s ordering instructions.
Prior to connecting the regulator, check the incoming line pressure, as these regulators can only withstand a
maximum pressure of ½ PSI (14” WC). If the line pressure is beyond this limit, a step-down regulator will be
required. The arrow forged into the bottom of the regulator body shows gas flow direction; it should point
downstream to the appliance. The air vent cap on the top regulator is part of the regulator and should not be
removed.
Any adjustments to regulators must be made only by qualified service personnel with the proper test
equipment.
RIGID CONNECTIONS
Double-check any installer-supplied intake pipes visually and/or blow them out with compressed air to
clear any dirt particles, threading chips, or other foreign matter before installing a service line. Those particles will
clog orifices when gas pressure is applied.
All connections must be sealed with a joint compound suitable for LP gas and all connections must be
tested with a soapy water solution before lighting any pilots.
FLEXIBLE COUPLINGS, CONNECTORS AND CASTERS
If the unit is to be installed with flexible couplings and/or quick-disconnect fittings, the installer must use a
heavy-duty, AGA design-certified commercial flexible connector of at least ¾” NPT (with suitable strain reliefs).
The flexible connector must comply with the standard for Connectors for Movable Gas Appliances, ANSI Z21.69
(or latest edition) CSA 6. 16 (or latest edition) and a quick-disconnect device that complies with the standard for
quick-disconnect devices for use with Gas Fuel should comply with ANSI Z21.41(or latest edition) CSA 6.9 (or
latest edition). If disconnection of the restraint is necessary, make sure to reconnect restraint after the appliance has
been returned to its originally installed position. Domestic gas or water connectors are not suitable.
Restraining device may be attached to the back frame/panel of the unit.
NOTE:
This appliance is not capable of being operated in the event of power failure. No attempt should be
made to operate this appliance during a power failure.
