Heatilator MH36A Operating Instructions Manual page 18

Do not pack insulation in spaces between the two shields or above
the shield inside the flashing. This may affect temperatures to ad-
jacent combustibles. See page 13 for minimum chimney height
above roof.
Detailed instructions for installation of the termination cap and storm collar are packaged with these parts. 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 termination cap be painted with a rust-resistant paint.
10. Install the Outside Air Kit
The outside air kit is required in a manufactured
housing fireplace installation. It is recommended to
utilize the shortest duct run to optimize the performance
of the outside air kit. The outside air kit inlet thimble
should be positioned at least 4 ft above the ground
level, in a manner that will not allow snow, leaves, etc.
to block the inlet.
The outside air kit is installed on either the left hand
or right hand side of the fireplace. Remove the cover
plate from the side of the fireplace assembly where
the air kit is to be installed. Install the outside air kit as
detailed in the installation instructions included with
it. See Figure 16 for handle location/operation.
The air kit handle may get hot while burning
the fireplace. Use care when operating the
handle.
