• Review Table 12.1 to verify this is the correct section for
the unit and furnace type installed. If not, refer to the
proper section as indicated for the unit as configured.
• For units that require vent extension kits, refer to Literature
#MCP15-574, "Installation Instructions, Extended Vent Kit,
Model MPR Gas Heat", otherwise install the vent
terminal(s) as shown in Figure 14.1. Note the following
installation steps:
D-Cabinet Units Only (refer to Figure 14.1)
Step 1: Insert the outer vent pipe with termination elbow for
the condensing furnace through the enclosure wall
grommet on one side of the unit and into the
rubber coupling on the power exhauster outlet.
Tighten the clamp on the flexible coupling to
secure the vent pipe.
Step 2: Verify that the bird screen is inserted in the
termination elbow and that the vent terminal elbow
is oriented to exhaust straight down.
Step 3: Install the vent terminal with bird screen for the
non-condensing furnace on one side of the unit
and secure with screws provided. Caulk the
mating surface before attaching.
Step 4: Install the combustion air hood on one side of the
unit using the screws provided. Caulk the mating
surface before attaching.
Step 5: Repeat Steps 1 and 4 for the heating sections on
the opposite side of the unit.
• Once complete, proceed to the "Condensate Drain and
