• Most power vent installations develop some
condensation in the vent piping. When using long runs
of venting or when the venting passes through cold or
unheated areas, considerable amounts of condensate
from the fl ue gases can develop. Provision must be
made for the condensate to drain freely from the
system or to be collected in a condensate trap(s) that
can be drained. Damage or fracture of the vent piping
may occur if the condensate is allowed to collect and
freeze. Pooling of condensate can restrict airfl ow and
can cause nuisance failures of the system.
AIR REQUIREMENTS
For safe operation an adequate supply of fresh,
uncontaminated air for combustion, dilution and ventilation
must be provided.
Note: Contaminated or dusty air may cause build-up on
the blower wheel resulting in nuisance shut downs.
