MANUFACTURED HOME INSTALLATION

In addition to the standard installation instructions, the following instruc- tions may be required by local, state or federal building codes:

• Installation should be in accordance with the Manufactured Home and

Safety Standard (HUD), CFR 3280, Part 24.

• The stove must be permanently bolted to the floor using two or three 1/4"

or 5/16" Ø x 5" lag screws as shown in Figures 4A, 4B, 5A and 5B.

• An outside air inlet must be provided for combustion and be unre-

stricted while unit is in use. Use a galvanized or stainless steel pipe

for the duct (the outside air inlet on the stove is 1-5/8” diameter).

The air intake on the exterior of the home should always be located

substantially below the flue termination. See Figures 4B and 15.

• Stove must be permanently electrically grounded to the steel chassis

of the home using a 8 GA copper wire and a serrated or star washer

(to penetrate paint or protective coating to ensure grounding). The

location selected for ground attachment to the stove must be dedicated

for this purpose. Grounding must comply with NFPA-70 standards,

CSA C22.1 in Canada, as well as any local codes.

Manufactured Home Exhaust Vent Pipe Installation Guidelines

Use only “PL” pellet vent pipe listed to UL 641 and ULC S609. The pipe should extend at least 3 feet above the part of the roof through which it passes. The top of the pipe should be at least 2 feet above the highest required elevation of any part of the manufactured home within 10 feet of the pipe (see Page 12, Manufactured Home Chimney Height Require- ments).

If the exhaust vent exits the manufactured home at a location other than the roof, and exits at a point 7 feet or less above the ground level on which the manufactured home is position a guard or method of enclosing the pipe shall be provided at the point of exit for a height of up to 7 feet. The openings, if any, in this guard shall not allow a 3/4” rod to pass through. A 1/2” rod could pass through but should not be able to touch the pipe when inserted through the opening a distance of 4 inches.
