IMPORTANT:
Vent-free gas log heaters add
moisture to the air. Although this is beneficial,
installing firebox in rooms without enough
ventilation air may cause mildew to form from
too much moisture. See
Air for Combustion
and Ventilation
, page 6.
IMPORTANT:
Make sure firebox is level. If fire
-
box is not level, log set will not work properly.
Note: Your firebox is designed to be used in zero
clearance installations. Wall or framing material can
be placed against any exterior surface on the rear,
sides, top or bottom of your firebox, except where
standoff spacers are integrally attached. If standoff
spacers are attached to your firebox, these spac
-
ers can be placed directly against wall or framing
materials. Use the dimensions shown for rough
opening to create the easiest installation.
Use dimensions shown for rough openings
to create the easiest installation (see
Built-In
Firebox Installation
, page 10).

Mantel Clearances for Built-In Installation
If placing custom mantel above built-in firebox,
you must meet the minimum allowable clear
-
ance between mantel shelf and top of firebox
opening shown in Figure 6, page 10. These
are the minimum allowable mantel clearances
for a safe installation. Use larger clearances
wherever possible to minimize the heating of
objects and materials placed on the mantel.

the vent-free gas log heater
to touch or extend beyond the
fireplace screen.
NOTICE: Surface temperatures
of adjacent walls and mantels be
-
come hot during operation. Walls
and mantels above the firebox
may become hot to the touch.
If installed properly, these tem
-
peratures meet the requirement
of the national product standard.
Follow all minimum clearances
shown in this manual.
NOTICE: If your installation does
not meet the minimum clearances
shown, you must do one of the
following:
• raise the mantel to an accept
