Table 2. Horizontal Vent / Combustion Air Parameters.
1.8 Locating Appliance for Correct
Horizontal Vent/Ducted Air Distance
From Outside Wall
The forced draft combustion air blower/blowers
in the appliance has/have sufficient power to pull air
and vent properly when the following guidelines for
horizontal air and vent are followed (
see Table 2
).
NOTE: On all model sizes, the vent collar size is
larger than the size of the vent pipe that can be used.
Vent collar size and horizontal pipe diameters can
be found in
Table 2
. The larger vent collar size is to
accommodate Category I (vertical) vent systems.
NOTE: When located on the same wall, the Pennant
combustion air intake terminal must be installed
a minimum of 12" (30cm) below the exhaust vent
terminal and separated by a minimum of 36 inches
(91cm) horizontally.
The air intake terminal must be installed high
enough to avoid blockage from snow, leaves and other
debris.
