body and 200 mm to the rear or to the wall, whichever is smaller.
USA and Canada - A chimney connector / venting extends horizontally
over the floor, protection must also cover the floor under the connector
/ venting and at least 2" (51 mm) to either side.

Chimney and Connector

May only be installed using listed 6" or 8" double wall connector pipe
with UL103HT listed factory-built chimney suitable for use with solid
fuels or masonry chimney. Horizontal connections not tested, refer to
local building codes for installation. May be installed with 6" connector
pipe and chimney using an 8" to 6" reducer. See installation instructions
for details. Clearances to connector shall be measured from 8" flue collar.
Restrictions apply! Read instructions before installing.
This appliance may be installed using 6" chimney in vertical installations
utilizing a 8" to 6" reducer (cat. # 71134) at the flue collar. If the venting
system is all vertical and the total vent length above the flue outlet exceeds
14 feet, it is recommended that the 8" to 6" pipe reducer is used and a
6" venting system be installed.

This appliance may be vented into a code-approved masonry chimney
with flue liner.
Warning: Chimney connector must be in good condition and kept clean.
Do not install damaged parts.
Residential chimney systems must be from the same brands of double
wall pipe as listed for mobile homes.
All of the stove connector pipe used must be of the same brand. The
chimney that the stove pipe transitions into may be a different brand.
Other than the transition of the stove pipe into the chimney, do Not mix
different brand vent components. Install all vent components per vent
manufacturer's instructions.
The chimney connector shall not pass through an attic or roof space,
closet or similar concealed space, or a floor, or ceiling. Where passage
through a wall, or partition of combustible construction is desired, the
installation shall conform to CAN/CSA-B365, Installation Code for Solid-
Fuel-Burning Appliances and Equipment.
There must be an effective vapor barrier at the location where the chimney
or other component penetrates to the exterior of the structure. Follow
the vent manufacturer's detailed instructions.
IMPORTANT NOTE: See Draft Requirements and Selecting a Proper
Venting System on Page 4 to assist you in choosing the proper venting
system for your installation.

Components Required For Installation

Legs AND bottom heat shield or pedestal.
Use all required components specified for this appliance. Do not
substitute.
WARNING: In the event that you remove the blower for any
reason, make sure a cover plate (available from Lennox Hearth
Products) is installed before using the heater. Excessive rear
wall temperatures will result if the stove is burned without the
cover plate. Note: The cover plate is not necessary if a blower
has never been installed because a knock-out will be in place
to act as the cover.
