Twist-lock the flue cap and seal.

Note: For multi-story vertical installations, a ceiling firestop
is required at the second floor, and any subsequent floors
(Figure 4.25). The opening should be framed to 254 mm
x 254 mm inside dimensions, in the same manner as
shown in Figure 4.22.

If the heater installation requires a vertical flue off the top
of the unit with no horizontal flue or elbows, the vertical
flue restrictor must be added. Reinstall heat shield when
completed. See Figure 4.26.

Fire Risk.

Explosion Risk.

• Any occupied areas above the first floor,

including closets and storage spaces, which
the vertical flue passed through must be
enclosed. The enclosure may be framed
and sheetrocked with standard construction
materials; however, refer to these installation
instructions for the minimum allowable
clearance between the outside of the flue
pipe and the combustible surfaces of the
enclosure. Do not fill any of the required air
space with insulation.
