Clearances
(Refer to Fig. 7, Page 9)
To ensure the safe installation into a masonry or fac-
tory-built fireplace, carefully observe the following
instructions:
1. Sidewall Clearances: The clearance from the in-
side of the front opening of the fireplace to any combus-
tible wall should not be less than 3¹⁄₂” (Fig. 7A)
2. Ceiling Clearances: The ceiling height should not
be less than 42” from the top of the fireplace opening. (Fig.
7A)
3. Mantel Clearances:
When installing an ANSI Z21.11.2 ventless appliance,
the finishing material used for the mantel must be rated
at 250°F or greater. Refer to firebox instructions for any
further information.
Without hood: If no hood is installed, then there must
be non-combustible material from the top front opening
of the fireplace to a height of at least 20 inches and the
full width of the fireplace. A combustible flat mantel shelf
can be no closer than 38¹⁄₂” from the top front of the
fireplace opening (Fig. 7B).
With hood:
If a hood is installed there must be non-
combustible material from the top front opening of the
fireplace to a height of 7¹⁄₂” and the full width of the fire-
place. A combustible flat mantel shelf may be installed
according to the detail in Figure 7C.
3A. Mantel Depth:
A combustible mantel can be no deeper than 8”, at 12”
above the hood. (Figs. 7B and 7C)
4. Grate Clearance
The minimum clearance between the front legs of the
grate and the front edge of the fireplace is 3” (Fig. 7B).
