Electrical
The standard blower motor requires 120 Volts AC for operation. The
fireplace is not dependent on the blower or an outside electrical supply to
operate. WARNING - Electrical Grounding Instructions - This appliance
is equipped with a three-prong (grounding) plug for your protection
against shock hazard and should be plugged directly into a properly
grounded three-prong receptacle. Do not cut or remove the grounding
prong from this plug.
Millivolt Valve
This appliance is operated with a millivolt valve and therefore burns even
during a power outage.
Fuel
This appliance comes from the factory equipped to burn natural gas at
a specified elevation. The appliance can be converted to burn LP (liquid
propane) by installing a conversion kit. Only Lennox Hearth Products
conversion kits can be used to convert from NG to LP or LP to NG.
Contact your Lennox Hearth Products dealer for details.
