Required ceiling and roof cut-out openings (see
Figure 11) must be carefully located to avoid
misalignment of the furnace and Roof Jack.
Note: Install only Roof Jack Assemblies listed
in Table 4 on this heating appliance.

Roof Jack Selection
1. Determine depth of ceiling cavity from center
1. Determine depth of ceiling cavity from center
of roof opening to center of ceiling opening.
(See Dimension “A” in Figure 16.)
(See Dimension “A” in Figure 16.)
2. Determine ceiling height and subtract height
of furnace. (See Dimension “B” in Figure 16.)
3. Add dimensions A + B (and X from Table 5
and Figure 18 if slant deck fl ashing is used).
The total length of (A + B + X) must be within
the minimum and maximum range of one of
the Roof Jacks listed in Table 4.
The total length of (A + B + X) must be within
