R EXHAUST AIR from various parts of home.
® i.e. bathrooms (if required), kitchens (if required), rooms
without operable windows, etc. and potentially basements.
NOTES:
1. Furnace blower need not operate to provide good air distribution/quality with this system.
2. Should furnace blower be required to operate to help distribute supply air, it may be:
A) - interlinked electrically (low voltage) with HRV for intermittent demand or,
B) - run continuously, though electrical consumption of furnace blower should be considered.
3. No separation requirements necessary between direct connection point and furnace.
4. Air streams through HRV do not represent any particular model. They may change in actual installation.
5. Weatherhood arrangement is for drawing purposes only. Six ft. (6') minimum separation required.
Ten in. (10") above grade minimum.

NOTES:
1. Furnace blower is required to operate when ventilation from HRV is required (when HRV is running).
It may be:
A) - interlinked electrically (low.voltage) with HRV for intermittent demand or,
B) - run continuously, though electrical consumption of furnace blower should be considered.
2. A minimum separation of 18" is required between the two direct connections.
3. The exhaust air connection should be upstream of the supply air connection to prevent exhausting
any fresh air.
4. Air streams through HRV do not represent any particular model. They may change in actual installation.
5. Weatherhood arrangement is for drawing purposes only. Six ft. (6) minimum separation required.
Ten in. (10") above grade minimum.
