WARNING: Never install the
firebox
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture,
clothing or other flammable
objects are less than 36" from
the front and 42" from the top
of firebox - for side clearances
see Figure 6, page 8
• in high traffic areas
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 4.
IMPORTANT:
Make sure the firebox is level.
If firebox 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 directly against any
exterior surface on the rear, sides or top of
your firebox, except where standoff spacers
are integrally attached. If standoff spacers
are attached to your firebox, these spacers
can be placed directly against wall or fram-
ing materials.
Use the dimensions shown for rough openings
to create the easiest installation (see
Built-In
Firebox Installation
, page 1).
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation
grills or ducts. You must provide two perma-
nent openings: one within 1" of the ceiling
and one within 12" of the floor. Connect these
items directly to the outdoors or spaces open
to the outdoors. These spaces include attics
and crawl spaces. Follow the
National Fuel
Gas Code ANSI Z223.1/NFPA 54, Section 5.3,
Air for Combustion and Ventilatio
n for required
size of ventilation grills or ducts.
IMPORTANT:
Do not provide openings for
inlet or outlet air into attic if attic has a thermo-
stat-controlled power vent. Heated air entering
the attic will activate the power vent.
