along horizontal length until flue pipe penetrates
outside wall.
** A minimum 1" clearance to combustibles permitted

This fireplace must be vented to the
outside. The venting system must NEVER
be attached to a chimney serving a separate
solid fuel burning appliance. Each gas
appliance must use a separate vent system.
Do not use common vent systems. Horizontal sections of this vent system
require a minimum of 3” clearances to
combustibles at the top of the flue and 1”
clearance at the sides and bottom until
the flue penetrates the outside wall. A
minimum 1” clearance all around the flue
is acceptable at this point of penetration. If
vertical rise is 7Z\x” feet or higher when top
venting, the clearance to combustibles is
1” on all sides of the horizontal run.
Vertical sections of this vent system require
a minimum of 1” clearance to combustibles
on all sides of the pipe.
