Burner Assembly Location
Centrally locate the unit in the fireplace, far enough
back into the firebox to accomplish adequate draft (if
use as a vented appliance is planned). Ensure that the
front grate feet sit inside the front edge of the fireplace
a minimum of 3". (Fig. 7B)

side of the front opening of the fireplace to any combus-
tible wall should not be less than 3¹⁄₂" (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).
