When direct venting through the wall, as shown in Figure 32, the
exhaust should terminate a minimum of 24” from the air intake. The
exhaust may be rotated up to 45 degrees left or right as long as the
24” distance is maintained.
The air intake screen can be removed for space heating at cold climate
installation to prevent potential air intake freeze up. If air intake screen
is removed during winter to prevent freezing it is recommended to re-
install the screen during non-space heating seasons.
If necessary to achieve the 12” minimum clearance above the highest
anticipated snow level or grade for the air intake install a snorkel,
similar to the exhaust, in the up position. Maintain the 24” distance
between the intake and exhaust terminations.
Optional cold climate sidewall direct vent kits are available: 318221-
000 for 2” vent systems and 318222-000 for 3” vent systems.
