Clearances

To ensure a safe installation, the following instructions
must be carefully observed.
1. Sidewall Clearances: Clearances from the side of
the fireplace opening to any combustible wall should
not be less than 2".
2. Ceiling Clearances: The ceiling height should not
be less than 36" from the top of the fireplace (Fig.
5a).
Mantel Clearances:
a. Mantel profile: The minimum distance above the
fireplace opening to combustible material project-
ing 1" (tile moldings, breast boards, etc.) is 13".
Combustible material projecting 6" (a mantel
shelf, for example) requires a minimum clearance
of 20¹⁄₄" above the fireplace opening. Required
clearance varies with the amount of projection.
(Fig. 5a)
The mantel profile must fall within the cross-sec-
tion shown in Figure 5a (with standard canopy)
or Figure 5b (if a AH3342 adjustable canopy is
used).

(Fig. 5b)
c. Heat resistant material: Any heat resistant mate-
rial suitable for a continuos operating temperature
of 120°C (248°F) must cover the wall surface di-
rectly above the fireplace opening and extend the
full width of the fireplace opening for a distance
of 9" above the opening of the fireplace. (Figs. 5a
and 5b)
d. Refer to Figure 6 for mantel leg clearances.
NOTE: Due to the continuous heat output of a
Vent Free Fireplace, occasional discoloration or
peeling of paint and varnish materials may be
noticed directly above the fireplace opening.
