There must be a minimum distance of 6 feet (1.8 m)
between the hoods to avoid cross-contamination

Refer to figure at right for connecting insulated ducts to the
exterior hoods. An “Anti-gust intake hood’’ should be installed
in regions where a lot of snow is expected to fall.

Make a water trap loop in the tube to prevent the unit from
drawing unpleasant odors from the drain source. Make sure this
loop is located OVER the “T” as shown. Run the tube to the floor
drain or to an alternative drain pipe or pail.
IMPORTANT
If using a pail to collect water, locate the tube end approximately
1” from the top of the pail in order to prevent water from being
drawn back up into the unit.
