Venting
This fireplace can be vented with Security™ Secure Vent™ pipe*. Coaxial
pipe diameters are 6-5/8” outer and 4” inner. The combustion air for this
fireplace 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 Pages
18-20) will be met.
Electrical
The standard fan motor requires 120 Volts AC for operation. The fireplace
is not dependent on the fan or an outside electrical supply to operate.
Millivolt Valve
This fireplace is operated with a millivolt valve and therefore burns even
during a power outage.
Fuel
This fireplace comes from the factory equipped to burn natural gas at a
specified elevation. The fireplace 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.
