air is accessed through a vented crawl space (AK4F) or through a
sidewall (AK4). See Figure 6 for instruction of operating air kit.

terminate in attic space.
The maximum height for the air vent can not exceed
3 feet below the flue gas outlet of the termination.

CHIMNEY PIPE
An IHP chimney system consists of 12", 18", 24", 36" and 48" snap-
lock, double-wall pipe segments, planned for maximum adaptability
to individual site requirements. Actual lengths gained after fitting
overlaps must be taken into consideration (lineal gain) and are given
in lineal gain chart (see Figure 7).
Lineal gain is actual measurable length of a part after two or more
parts are connected. For Canada, use chimney parts designated "HT".
