Venting
This stove can be vented with Security™ Secure Vent™
pipe*. Coaxial pipe diameters are 6-5/8” outer and 4” inner.
The combustion air for this stove is drawn from outside the
house through the outer DV (direct vent) pipe. Room air is
not required for combustion.
When planning your installation, select the correct length of
vent pipe for your particular requirements. Determine the
minimum clearance to combustibles from the rear of the
unit to the wall. It is also important to note the thickness
of the wall. Before cutting the vent hole through the wall
make sure that ALL vent and termination clearances (see
page 16) will be met.
Electrical
The standard fan motor requires 120 Volts AC for operation.
The stove is not dependent on the fan or an outside electri-
cal 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 stove is operated with a millivolt valve and therefore
burns even during a power outage.
Fuel
This stove comes from the factory equipped to burn natural
gas at a specified elevation. The stove can be converted to
burn LP gas (liquid propane) by changing the cassette (valve
and pilot assembly) or 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.
