• It is recommended that the furnace blower 

run continuously or HRV operation
be interlocked with the furnace blower

• Check local codes /authority having 

jurisdiction for acceptance

Note: Option 1 is the pre-
ferred/recommended method
when doing a simplified
installation

1. Furnace blower may be required to operate when ventilation from HRV/ERV is required.  The furnace should be
set to run continuously or interlocked with HRV/ERV.
2. The exhaust air connection should be upstream of the supply air connection to prevent exhausting any fresh air.
3. Weatherhood arrangement is for drawing purposes only.  Six feet (2m) minimum separation recommended.
Eighteen inches (460 mm) above grade minimum.
4. Due to the differences in pressure between the HRV/ERV and the equipment it is being connected to, the
HR/ERV’s airflow must be confirmed on site, using the balancing procedure found in the installation manual.
