1. Furnace blower must operate when ventilation from HRV is required. The fur-
nace should be set to run continuously or interlocked with HRV. See page 15.
2. A minimum separation of 1m (39'') is recommended between the two
direct connections.
3. In order to prevent exhausting any fresh air, the HRV's exhaust air connection
should be upstream of the HRV's supply air connection when ducting to the
furnace's cold air return.
4. Due to the difference in pressure between the HRV and the equipment it is
being connected to the HRV's airflow must be balanced on site, using the
procedure found in the section "AIRFLOW BALANCING"
