* Other approved chimney brand is Simpson Dura-Vent DV-GS.
Hey Marina, the reason for the change
on this one is that were going to use a
9” pipe now that will be installed by us
here at the factory. So were just deleting
the 8” pipe off the packaging contents. If
you have any questions on either please
let me know.

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
15) 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.
