• For the PD Dual Fuel Ranges, a neutral supply
wire must be provided from the power source
(breaker/fuse panel) because critical range com-
ponents, including the surface burner spark
reignition module, require 120 VAC to operate
safely and properly. An improper 120/240 VAC
power supply will cause malfunction, damage
this appliance, and possibly create a condition of
shock hazard. If the correct power supply circuit
is not provided, it is the responsibility and obliga-
tion of the installer and user to have proper power
supply connected. This must be accomplished in
accordance with all applicable local codes and
ordinances by a qualified electrician. In the ab-
The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve
during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig
(3.5 kPa.).
The appliance and its individual shut off valve must be disconnected from the gas supply piping system
during any pressure testing of the system at test pressures in excess of 1/2 psig (3.5 kPa.).
When checking the manifold gas pressure, the inlet pressure to the regulator should be at least 6" W.C.
(14.9 mb) for natural gas or 11" W.C. (27.4 mb) for propane.
Do not attempt any adjustment of the pressure regulator.
