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 7.
IMPORTANT: Make sure 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 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 spacers can
be placed directly against wall or framing ma-
terials. 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
