Use the base bottom panel as a template to mark floor opening locations (see Figure 2). Cut a
square opening in the floor for the supply air connector duct. Cut the opening 1-inch larger
than the square template opening. (duct requires 1-inch clearance to combustible floor). Cut a
combustion air duct opening in the floor 1/8-inch larger than the template opening.
Figure 2.
After cutting openings in the floor, place the bottom panel in position. Mark the square
opening location on the distribution duct at the connection point of the connector duct.
Remove the bottom panel. Cut an opening in the distribution duct slightly larger than the
connector duct. (refer to Figure 2 for location of this cut.) Cut the connector duct to length.
Install the connector duct. Bend over each tab. Insure an airtight seal by using high
temperature sealant or tape on the joint. Reinstall the bottom panel over the connector duct.
Insert and secure the combustion air duct. Put the base top assembly in place (see Figure-3).
IMPORTANT
: A combustion air duct must be used. If the underside of the mobile home is
skirted or enclosed (e.g. enclosed in a crawlspace), the combustion air intake should exit
through the skirting, or enclosure, if at all possible. All joints and seams of supply ducts and
combustion air ducts must be closed with a sealing method suitable to the application
conditions and temperatures ( e.g. high temperature silicone caulk and/or aluminum tape).
Notice:
If desired, combustion air can be brought in thru the roof of the dwelling and into to the
furnace cabinet with Thermo Products Kit AOPS7512. See your local Thermo Pride
representative for details or call customer service.
