NOTE: While a condensate drain connection for the
vent system is required on all XFiire installations, the
drain can be accomplished in several different ways.
The figures in this section show the drain from the heat
exchanger, however, this can also be accomplished using
an additional inline collector for condensing stacks or an
additional inline vertical or horizontal collector available
from several of the listed vent manufacturers.
Combustion air supplied from outdoors must be free
of particulate and chemical contaminants. To avoid a
blocked flue condition, keep the vent cap clear of snow,
ice, leaves, debris, etc.
The approved flue direct vent cap must be installed in
accordance with its listing. See Table Q and Table R .
A WARNING: Mixing of different manufacturers
venting material is not permitted as this may create an
unsafe condition.

The XFiire heaters may be vented horizontally (either using
room air for combustion or ducted air for combustion) as
shown in the following figures. The air intake terminal may
be located in a different pressure zone (i.e. on different
walls) from the vent termination. See Figure 34.
