MANUFACTURED (MOBILE) HOME REQUIREMENTS
Approved for USA only. This appliance is not approved for
installation into a manufactured home in Canada.
This stove is certified as a Room Heater, Solid Fuel Type
and may be used in Manufactured Housing providing the
following requirements are followed:
• WARNING: DO NOT INSTALL IN SLEEPING
ROOM.
• An outside air inlet must be provided for combustion
and be unrestricted while unit is in use.
• Regulations require that the appliance must be se-
cured to the floor and grounded to the chassis. See
Securing the Stove to the Floor (and) Grounding
Stove, following.
• CAUTION: THE STRUCTURAL INTEGRITY OF
THE MOBILE HOME FLOOR, WALL, AND CEIL-
ING/ROOF MUST BE MAINTAINED.
VENTILATION REQUIREMENTS
THE FRESH AIR REQUIREMENTS OF THIS APPLI-
ANCE MUST BE MET WITHIN THE SPACE WHERE IT
WILL BE INSTALLED.
Ventilation is essential when using a solid fuel burning
heater. The combustion process of this heater uses oxy-
gen from inside the dwelling and it may be necessary to
open a window or to duct outside combustion air directly
to the appliance (as outlined in this manual). Modern
construction standards have resulted in homes that are
highly energy-efficient and that allow little heat loss and
air transfer. Other appliances in the dwelling also con-
tribute to removing air from the dwelling (i.e. clothes dry-
ers, exhaust fans, fireplaces, and other fuel burning ap-
pliances). If the available fresh air delivery in the dwelling
is insufficient to support the demands of these appli-
ances, problems can result (i.e. excessive negative
pressure can develop in the dwelling which will affect the
rate at which this appliance can draft [See Draft Re-
quirements, page 10], icing can develop in some envi-
ronments, etc.).
OUTSIDE COMBUSTION AIR
The following 2 optional kits are required to deliver out-
side air to this appliance. Contact your dealer to order.
Catalog # 14M67 Outside Air Floor Duct
Catalog # 14M68 Back Cover Plate
In all manufactured (mobile) homes and in many site built
residences (subject to local code), a stove may be required
to use outside air for combustion. A 5 ¼” square” outside
air floor duct Back Cover Plate is available through your
dealer.
This stove can take in outside air directly through the base.
This type installation requires a hole through the floor protec-
tor and the use of outside air floor duct to penetrate into the
air space below the home.
NOTES: The floor air duct can be positioned anywhere
2" in from either side under the pedestal. The floor air
duct opening must be protected from any possible ob-
struction including loose floor insulation. This part can be
purchased from your local dealer.
SECURING THE STOVE TO FLOOR
Manufactured (Mobile) Homes Only
Once the floor air duct and hearth pad are in position
confirm that the hole of the hearth pad is aligned with the
outside air opening. Next position and align the stove on
the hearth pad. Manufactured Home installations require
that the stove be secured to the floor. This ensures that
the stove will not shift if the Manufactured Home is ever
moved. To do this, drill two holes (use a marking instru-
ment long enough and small enough to fit through the (4)
four holes in the pedestal base and mark the hearth pad.
Then remove the stove. Drill the (4) four holes, (2) two
on each side of the pedestal base) with a 1/4" drill bit.
Drill down through the hearth pad and the Manufactured
Home floor. Use 1/4" lag bolts and secure to the Manu-
factured Home floor.
NOTE: If the composition of the manufactured home
floor is of light particleboard construction, you will
be required to secure the stove with regular hex
head bolts and nuts. This will ensure that the bolts
will not rip out of the floor when the manufactured
home is being moved.
