Stale Air Exhaust System
The stale air exhaust system draws air from the points in
the house where the worst air quality problems occur.
Stale air ducts should be installed in the bathroom,
kitchen, and laundry room. Applications such as green-
houses, atriums, swimming pools, saunas, etc. have
unique ventilation requirements which should be
addressed with an isolated ventilation system. Also, the air
handler return duct may be used to exhaust from. In this
method, the exhaust air is not ducted back to the HRV with
"dedicated lines" from bathrooms, kitchens, etc. Instead,
the exhaust air is drawn out of the cold air return of the air
handler. The air handler blower must be running when
the unit is operating for this system to be effective.
Balancing Dampers and Grilles
Balancing dampers and/or adjustable grilles should be
used to balance the flow rates into and out of various
rooms.
Grilles or diffusers should be positioned high on the wall or
in the ceiling. Kitchen exhaust grilles must never be con-
nected to a range hood. They should be installed at least 4
feet (1.2m) horizontally away from the stove. A hinged
6”X10” (150 X 250mm) rectangular kitchen exhaust grille is
available as part number. This grille includes a removable
grease filter. Canadian building codes require that kitchen
grilles be equipped with washable filters.
Field-supplied balancing dampers should be installed
external to the unit to balance the amount of stale air
being exhausted with the amount of fresh air being
brought into the house. Refer to Air flow Balancing section.
The Round Diffuser is available in
4" (100mm)
5” (125mm)
6" (150mm)
8" (200mm)
Drain Connection (HRV Only)
During a defrost cycle, the HRV may produce some con-
densation. This water should flow into a nearby drain, or
be taken away by a condensate pump.
The HRV cabinet has prepunched holes for the drain (see
below). Insert the drain spout through the hole in the drain
pan. Make certain the rubber washer is on the drain spout
before inserting.
Construct a P-Trap by looping the condensate hose and
taping in place.
Pour a cup of water into the P-Trap to create a water seal
which will prevent odours from being drawn up the hose
and into the fresh air supply to the HRV.
