Floor Protection
USA - The floor in front and under the heater must be protected
with a minimum of 3/8” (10 mm) thick noncombustible material.
The covering must extend 16” (406 mm) in front of the door
opening of the heater and 8” (203 mm) to either side of the door
opening and 5-1/2” (140 mm) to the rear or to the wall, whichever

The covering must extend 457 mm in front of the door opening of
the heater and 200 mm to either side of the stove body and 200
mm to the rear or to the wall, whichever is smaller. In all installa-
tions a 457 mm minimum hearth extension (in front of the stove)
is required as measured from the door opening of the unit.

Clearances to combustible surfaces can be reduced with the use of
listed double wall connector pipe. See the clearances with double
wall pipe on the following page.

(1219 mm) depth. Minimum ceiling height is 84” (2134 m).

Mobile Home Installations
This appliance is approved for installation into a mobile home
in the USA ONLY!
Installation should be in accordance with the Mobile Home
Construction and Safety Standard, Title 24 CFR, Part 3280 (in
Canada CAN/CSA Z240 MH), or, when such a standard is not
applicable, the Standard for Mobile Home Installations, ANSI
A225.1.
All mobile home installations require an outside air kit (cat. no.
71111 or 71112). The stove must be bolted to the floor and
grounded to the chassis of the mobile home.
WARNING: DO NOT INSTALL IN SLEEPING ROOM OF A
MOBILE HOME.
CAUTION: THE STRUCTURAL INTEGRITY OF THE MO-
BILE HOME FLOOR, WALL AND CEILING/ROOF MUST BE
MAINTAINED.
Approved Chimney* - Your stove is approved for use with Class
A, UL 103 HT (U.S.) / ULC-S629 (Canada) Listed Residential Type
and Building Heating Appliance Chimney (HT chimney - 2100°
Fahrenheit) and double wall connector pipe from Security™
Chimneys.
Clearances to connector shall be measured from 6" flue collar.
Restrictions apply! Read instructions before installing.
Chimney and Connector
Minimum 6" diameter, minimum 24 MSG black steel connector
pipe with listed factory-built chimney suitable for use with solid
fuels or masonry chimney. Horizontal connection not tested, refer
to local building codes for installation. Restrictions apply! Read
instructions before installing.
Clearance dimensions are to 6” (152 mm) flue collar. If a single
wall connector pipe with shield is used, a 1 inch air space is
needed between pipe and shield. Shield attaches to rear of stove
pipe and must run from stove top to ceiling. Pipe shield shall be
UL listed.
Residential chimney systems must be from the same brands as
listed for mobile homes but connector pipe may be double wall,
single wall or single wall with shield as listed above.
Connector pipe and chimney must be of the same brand.
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.
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 Base.
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.
* Other approved chimney brands are Projet, Jakes Evans/GSW,
Dura-vent, Metal Fab, Ameri-Tec, Metalbestos and Industrial
Chimney (ICC).
