INSTALLATION
Figure 3b
Vent Terminal Configurations for Through the Wall Venting:
When venting through the wall, the exhaust terminal must exit the structure at a
minimum distance of 16 in (40.6 cm) from the intake terminal. The exhaust
terminal must not be located below the intake terminal for any reason (see
Figure 4a below for examples of acceptable vent terminal configurations).
Figure 4a
When local conditions present a risk of ice accumulation on the vent terminals,
the configurations in 4b and 4c or the concentric termination are preferred.
The air intake screen can be removed for cold installations, but this may make
the air intake susceptible to debris buildup from birds or other animals. If the air
intake screen is removed to prevent freezing, it is recommended that the air
inlet screen be installed during the spring.
CAUTION
NEVER INSTALL AIR INTAKE ABOVE EXHAUST.
