central vacuum vent
• Gas meter exhaust, gas barbecue-grill

ONNECTING THE
RAIN
Cut 2 sections of the plastic tube, minimum 12" long, and attach them to each inner drain
fitting, located under the unit.
Join both short sections to the "T" junction and main tube as shown, to prevent the unit from
drawing unpleasant odors from the drain source.
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.
