Orifice Size/Altitude Adjustment
The Epic™ Stove
For altitudes above 2,000 feet (In Canada 4,500 FT/1370
M),the orifice should be de-rated by 4% for every 1,000 feet
to maintain the proper ratio of gas to air. Improper orifice
sizing may result in damage and unsafe conditions. Chang
ing the orifice should only be done by a qualified service
technician. Contact your Lennox Hearth Products dealer for
proper orifice sizes. (see Page 26 for more information).
Smoke Detectors
Since there are always several potential sources of fire in
any home, we recommend installing smoke detectors. If
possible, install the smoke detector in a hallway adjacent
to the room (to reduce the possibility of occasional false
activation from the heat produced by the appliance). If your
local code requires a smoke detector be installed within
the same room, you must follow the requirements of your
local code. Check with your local building department for
requirements in your area.

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
17) 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.
Instructions - This appliance is equipped with a threeprong (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.
