Figure 54: Surface mount
power vent detail.
Use the Surface mount power vent
unit (Figure 54) if the power vent is to
be located on the roof of a structure
(Figure 48). The Surface mount power
vent unit can also be used on a wall.
The Surface mount power vent unit
must use the HeliFire 360 inlet vent
box.
Use the Flush mount power vent on
outside vertical walls only. The Flush
mount power vent box contains both
the exhaust fan which is pulling air
from the HeliFire 360, and the air inlet
and restrictor which regulates the
proper air flow into the HeliFire 360.

restrictor plate works, “Combustion
