G. Outside Air Kit (Required on both sides)
Outside air kits must be used for combustion and to pro-
vide cooling air to prevent overheating. Hearth & Home
Technologies recommends you utilize the shortest duct run
to optimize the performance of the outside air kit and in-
stall a P-Trap (see Figure 3.10). The outside air inlet hoods
should be positioned in a manner that will not allow snow,
leaves, etc. to block the inlet. In some installations the air
duct may need to be run vertically. In such an installation,
a 3 ft (914 mm) height difference must be maintained from
the top of the uppermost chimney section to the outside air
inlet hoods.
Note: Maximum length is 40 feet.
