Nu-Air Ventilation Systems Inc. - HRV Operating &Installation Manual
Rev October 10, 2010 - 10 -
3.4. Mounting & Noise Control
For maximum efficiency, the HRV should be installed in a heated
area. The HRV is designed to be hung from the ceiling by way of the
anti-vibration straps supplied. Avoid hanging the HRV directly below
a bedroom or other quiet area.
Connecting To Other Equipment - Residential Applications
Interconnection with a forced air furnace duct system is permissible (see Section 3.2.2); however, your
Nu-Air HRV is not intended to be connected to any other equipment or appliances.
Flexible ducting may be desired in some installations for
noise abatement. To ensure effective air flow, use only as
much flexible ducting as necessary and keep it taut.
3.5. Ductwork
Duct runs should be straight with a minimum of bends
and elbows. Joints should be tight fitting and sealed with
duct tape or duct sealer.
RECOMMENDATION: Use galvanized duct whenever
possible. Although flexible duct can be used, its use
should be restricted to areas indicated (outside hoods
and unheated spaces).
Ducting must be supported according to the
manufacturers specified hanger system and
intervals.
Be sure to seal all pipe joints with foil tape or a
duct sealant.
When possible, form elbow joints so that they are
as straight as possible.
RECOMMENDATION: An engineer or other qualified
person should design the duct system.
