SHR 1504 Installation Manual

DIRECT CONNECTION of both the HRV SUPPLY AIR STREAM &

EXHAUST AIR STREAM to the FURNACE COLD AIR RETURN & SUPPLY AIR SIDE

Simplified Installation

Option 2

(Supply/Return Method)

NOTES:

1. Furnace blower must operate when ventilation from HRV is required.

The furnace should be set to run continuously or interlocked with HRV.

2. The exhaust air connection should be upstream of the supply air con-

nection to prevent exhausting any fresh air.

3. Weatherhood arrangement is for illustrative purposes only. 3m (10')

minimum separation and 460mm (18") above grade is recommended.

4. Due to the differences in pressure between the HRV and the equip-

ment it is being connected to, the HRV‘s airflow must be balanced on

site, using the procedure found section "AIRFLOW BALANCING".
