Outside Air
MOBILE HOME INSTALLATION
Once you have properly marked the position of
your unit and the oor protection as outlined in
the Residential Installation items #1 through #8, a
supply of fresh air has to be supplied to your unit.
See Optional Outside Air Kit instructions in this
manual.
Place your unit in position and secure it to the
oor using two lag bolts 3/8" (10mm) x 3-1/2"
(89mm) through the two holes inside the pedestal
base. It is important to maintain the structural
integrity of the Mobile Home oor, walls and roof
when installing your unit.
For Mobile Home units installed in the U.S. the
unit must be grounded using a #8 ground wire
with approved termination and star washer.
In addition to standard installation instructions
the following requirements are mandatory for
installation in a mobile home.
1. The stove must be permanently bolted to
the oor of the Mobile Home using the oor
screws provided.
2. The stove must have a permanent outside air
source for combustion.
3. The stove must be electrically grounded to
the steel chassis of the Mobile Home.
4. A listed double-wall connector chimney
system, roof thimble, spark arrestor and roof
ashing kit suitable for use in Mobile Homes
must be used.
5. If the chimney exits the Mobile Home at a
location other than through the roof, and
exits at a point 7ft. (2130mm) or less above
the ground level on which the Mobile Home
is positioned a guard or method of enclosing
the chimney shall be tted at the point of exit
for a height up to 7ft. (2130mm).
6. The chimney shall be attached directly to the
room heater and shall extend at least 3 ft.
(914mm) above the part of the roof through
which it passes. The top of the chimney
should project at least 2ft. (610mm) above
the highest elevation of any part of the Mobile
Home within 10 ft. (3048mm) of the chimney.
7. The chimney system shall comply with Local
Requirements.
8. Any openings in a chimney guard where
required must not permit the entrance of 3/4"
(19mm) diameter rod.
9. CAUTION: THESTRUCTURAL INTEGRITY
OF THE MOBILE HOME ROOF, FLOOR,
WALLS AND CEILING MUST BE
MAINTAINED.
10. Check any other local building code as other
local codes may apply.
11. WARNING: DO NOT INSTALL IN A
SLEEPING ROOM OF A MOBILE HOME.
12. Use silicone to create an eective vapour
barrier at the location where the chimney or
other component penetrates to the exterior
of the structure.
CAUTION: At no time use unlabelled
parts, or substitute parts made for
another chimney system.
Install as per chimney manufacturer's
installation instructions.
For Canadian Installations: see Outside
Air Kit - Part # 846-502.
There are further requirements when installing
this unit into a mobile home in Canada Only.
WARNING: Operate only with door
fully closed - open feed door to feed
re only.
1. Identify the position of the outside air damper by the orientation of
the metal handle that rests outside the galvanized pipe. The metal
handle and the damper disc are in line with each other. This means
that if the metal handle is in a horizontal position, the damper is at
and fully open.
2. Open the damper fully whenever you start a re. This will allow the
outside air to be drawn in the pedestal base eliminating any potential
smoke escaping the stove and entering the room. (Negative air
pressure)

8. If you are using a horizontal connector,
the chimney connector should be as high
as possible while still maintaining the 18"
(457mm) minimum distance from the
horizontal connector to the ceiling.
NOTE: Residential Close Clearance
and Alcove installations require
a listed double wall connector
from the stove collar to the

dealer or installer for information on other
options available to you.
STEP-BY-STEP CHIMNEY
AND
CONNECTOR INSTALLATION
Note: These are a generic set of chimney
installation instructions. Always
follow the manufacturers own
instructions explicitly. Check the
Minimum Recommended Flue
Heights section (Table 1).
1. With your location already established, cut
and frame the roof hole. It is recommended
that no ceiling support member be cut for
chimney and support box installation. If it is
necessary to cut them, the members must
be made structurally sound.
2. Install radiant shield and support from above.
3. Stack the insulated pipe onto your nish
support to a minimum height of 3 feet above
the roof penetration, or 2 feet above any
point within 10 feet measured horizontally.
There must be at least 3 feet of chimney
above the roof level.
Note: Increasing the chimney height
above this minimum level will
sometimes help your unit to
“breathe” better by allowing
a greater draft to be created.
This greater draft can decrease
problems such as, dicult start-
ups, back-smoking when door is
open, and dirty glass. It might be
sucient to initially try with the
minimum required height, and then
if problems do arise add additional
height at a later date.
4. Slide the roof ashing over your chimney
and seal the ashing to the roof with roong
compound. Secure the ashing to your roof
with nails or screws.
5. Place the storm collar over the ashing,
sealing the joints with a silicone caulking.
6. Fasten the raincap with spark screens (if
required) to the top of your chimney.
7. To complete your chimney installation, install
the double wall connector pipe from the
stove’s ue collar to the chimney support
device.
This stove may be connected to a lined masonry
chimney or a listed factory built chimney suitable
for use with solid fuels and conforming to ULC629
in Canada or UL-103HT in the USA. Do not connect
it to a chimney serving another appliance. To do
so will aect the safe operation of both appliances,
and will void the stove warranty. You must comply
with the local authority having jurisdiction and/or
in Canada, CSA installation standard B365-M87.
The chimney connector must be 6" diameter, 24 MSG
Black/Blue steel. Do not use aluminum or galvanized
steel, they cannot properly withstand the extreme
temperatures of a wood re. The chimney connector
between the stove and the chimney should be as
short and direct as possible.
The chimney connector must be attached to either
an approved masonry chimney or one of the listed
factory built chimneys suitable for use with solid
wood fuel. All joints must be tight and fastened
with sheet metal screws.
WARNING
THE CHIMNEY CONNECTOR IS
TO BE USED ONLY WITHIN THE
ROOM, BETWEEN THE STOVE
AND CEILING/ WALL. NEVER
USE A CHIMNEY CONNECTOR
TO PASS THROUGH AN ATTIC
OR ROOF SPACE, CLOSET OR
SIMILAR CONCEALED SPACE,
OR A FLOOR, OR CEILING. AN
EFFECTIVE VAPOR BARRIER
MUST BE MAINTAINED AT THE
LOCATION WHERE THE CHIMNEY
OR COMPONENT PENETRATES
TO THE EXTERIOR OF THE
STRUCTURE. ALWAYS MAINTAIN
THE MINIMUM CLEARANCES TO
COMBUSTIBLES AS REQUIRED
BY THE APPLICABLE BUILDING
CODES.

8 | F2450 Wood Stove
FACTORY BUILT CHIMNEY
When a metal prefabricated chimney is used, the manufacturer's installation instructions must be followed. You must also purchase and install the
ceiling support package or wall pass-through and "T" section package, restops (where needed), insulation shield, roof ashing, chimney cap, etc.
Maintain proper clearance to the structure as recommended by the manufacturer. The chimney must be the required height above the roof or other
obstructions for safety and proper draft operation. The space heater is to be connected to a factory-built chimney conforming to CAN/ULC-S629,
Standard for 6500C Factory-Built Chimneys.
MASONRY
CHIMNEY
Ensure that a masonry chimney meets the
minimum standards of the National Fire
Protection Association (NFPA) by having it
inspected by a professional. Make sure there
are no cracks, loose mortar or other signs of
deterioration and blockage. Have the chimney
cleaned before the stove is installed and
operated. When connecting the stove through a
combustible wall to a masonry chimney, special
methods are needed.
Ensure that an eective vapour barrier at the
location where the chimney or other component
penetrates to the exterior of the structure.
MASONRY
FIREPLACE
There are listed kits available to connect a stove
to a masonry replace. The kit is an adapter
that is installed at the location of the replace
damper. The existing damper may have to be
removed to allow installation.
Ensure that an eective vapour barrier at the
location where the chimney or other component
penetrates to the exterior of the structure.
This unit is designed to use either a 5.5" (140mm)
or 6" (152mm) ue liner only in the connes of

WARNING:

ROOM
CAUTION: The structural integrity of the mobile home
oor, wall and ceiling/roof must be maintained.
Draft is the force which moves air from
the appliance up through the chimney.
The amount of draft in your chimney
depends on the length of the chimney,
local geography, nearby obstructions and
other factors. Too much draft may cause
excessive temperatures in the appliance
and may cause damage. An uncontrollable
burn or excessive temperature indicates
excessive draft. Inadequate draft may
cause back pung into the room and
plugging of the chimney. Inadequate
draft will cause the appliance to leak
smoke into the room through appliance
and chimney connector joints. Ensure
the heater is installed in areas that are
not too close to neighbors or in valleys
that would cause unhealthy air quality
or nuisance conditions.
