GAS CONNECTION
-
The gas inlet line size of this appliance is 3/4" NPT. For proper operation, the gas supply service line
must be the same size or greater than the inlet line size of the appliance. The gas line size must not be reduced at any point along
the supply line.
MANUAL SHUT-OFF VALVE
-
A gas pressure regulator and a contractor-supplied shut-off valve must be plumbed in the gas
service line ahead of the appliance – in a physical location where it can be reached quickly in the event of an emergency.
Visually double check any installer-supplied intake pipes and/or blow them out using compressed air to clear any dirt or debris,
threading chips, or other foreign matter – before installing a service line. Those particles will clog gas orifices when gas pressure is
applied. Compounds used on threaded joints of this appliance piping must be resistant to the action of NG and LP gas and provide
a gas tight seal to prevent leaks.
The gas pressure regulator must be installed in the gas line – failure to install a pressure regulator will void the equipment
warranty. The regulators supplied with ranges have 3/4" NPT connections; the regulator is adjusted at the factory for
5" W.C. (water column) manifold gas pressure (natural gas) or 10" W.C. manifold gas pressure for propane gas operation.
Before connecting the regulator, check the incoming line pressure – as these regulators can only withstand a maximum inlet pressure
of 14" W.C. (1/2 PSI); exceeding this pressure will damage them. If the gas supply line pressure is greater than this amount, a step-
down regulator will be required. A gas flow direction arrow is cast into the body of the regulator to minimize installation error – it
should point downstream to the appliance. The blue air vent cap on the top of the regulator is part of the regulator and should not
be removed.
Any adjustment to the regulator must be made only by qualified and licensed service
personnel with the proper calibrated test equipment. Gas connections should be performed
by a qualified licensed contractor.

INSTALLATION - GAS STANDARDS AND CODES
IMPORTANT -
The installation of this appliance must conform to local codes or, in the absence of local codes, with the National Fuel
Gas Code ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149-1, or the Propane Installation Code, CAN/CGA-B149-2
as applicable, including:
1. The appliance and its individual shut off valve must be disconnected from the gas supply piping system during any
pressure testing of that system at test pressure in excess of 1/2 psi (3.45 kPa).
2. The appliance must be isolated from the gas supply piping system by closing the individual manual shut-off
valve during any pressure testing of the gas supply piping system.
When installing the pressure regulator - remember it can only handle 1/2 PSI. In
every LPG installation, you have high source pressures, ranging from 20 PSI to 100
PSI. If the high pressure gas line from the LPG tank is directly connected to the unit
without the proper step-down regulator, it will rupture the diaphragm in the valve,
rendering it useless.
