3.1 chimney
Your appliance may be connected to a factory built or masonry chimney. If you are using a factory built chimney,
it must comply with ULCS629 (Canada) or UL103 (USA) standards. It must therefore be a 6" (152mm) HT Type
(2100°F) chimney. It is extremely important that it be installed according to the manufacturer’s specifications.
The manufacturer’s installation instructions and specified clearances should always be followed in accordance with
local and national codes. In Canada the CSA B365 and the CSA C22.1 installation codes are to be followed. In
the USA the ANSI NFPA 70 and ANSI NFPA 211 installation codes are to be followed.
Chimney and chimney connector must be in good condition and kept clean.

WARNING
• Never install a single wall slip section or smoke pipe in a chase structure. The higher temperature of this single
wall pipe may radiate sufficient heat to combustible chase materials to cause a fire.
• Do not connect this appliance to a chimney system serving another appliance.
• To avoid danger of fire, all instructions must be strictly followed, including the provision of air space clearance
between chimney system and enclosure. To protect against the effects of corrosion on those parts exposed to
the weather, we recommend that the chase top be painted with a rust-resistant paint.
• Do not fill any framed space around the chimney with insulation or any other material. Insulation placed in this
area could cause adjacent combustibles to overheat.
• Maintain a minimum 2” (51mm) air clearance to all parts of the chimney system at all times (this excludes the
chimney connection). Failure to maintain this 2” (51mm) air clearance will cause a structure fire. Never fill this
space with any type of material.
• Detailed instructions for installation of the chase top, storm collar and termination cap are packaged with these
parts.
• Do not cut rafters or ceiling joists without first consulting a building official to ensure structural integrity is not
compromised.
• Firestop spacers must be used whenever the chimney penetrates a ceiling/floor area.
• The total horizontal vent length should not exceed 40% of the chimney height above the appliance all horizontal
smoke pipe must slope slightly upwards a minimum of 1/4” (6.4mm) per foot and all connections must be tight
and secured by three sheet metal screws equally spaced. An uninsulated smoke pipe shall not pass through
an attic, roof space, closet or similar concealed space, or through a floor, ceiling, wall or partition, or any
combustible constructions.
• This appliance must be connected to a code-approved masonry chimney with a flue liner.
• Do not use any makeshift materials during installation.
• A chimney shall comply with the Standard for Factory-Built Chimneys for Residential Type and Building Heating
Appliances, UL 103.
• The chimney shall be attached directly to the room heater and shall extend at least 3 feet (0.9m) above the part
of the roof through which is passes. The top of the chimney is to be at least 2 feet (0.6m) above the highest
required elevation of any part of the mobile home within 10 feet (3m) of the chimney.
• All roof-chimney terminations shall be able to be readily removed at or below an elevation of 13 1/2 feet (4.1m)
above ground level and reinstalled without the use of special tools or instructions. The chimney assembly shall
be provided with a mechanical means to secure the chimney to the ceiling support box.
• When the chimney exits the mobile home at a location other than through the roof, and exits at a point 7 feet
(2.1m) or less above the ground level on which the mobile home is positioned, a guard or method of enclosing
the chimney shall be provided at the point of exit for a height up to 7 feet (2.1m). The openings in a chimney
guard shall not permit the entrance of a 3/4” (19.1mm) diameter rod and/or contact with the chimney by a 1/2”
(12.7mm) diameter rod inserted through the opening a distance of 4” (102mm).
• The chimney shall be provided with a spark arrester secured to the chimney. The net free area of the arrester
above the chimney outlet shall be not less than four times the net area of the chimney outlet, and the vertical
height of the arrester above the chimney outlet shall be not less than one-half the diameter of the chimney flue.
Openings shall not permit the passage of a sphere having a diameter larger than 1/2” (12.7mm) and shall permit
the passage of a sphere having a diameter of 3/8” (9.6mm).
