SIMPLIFIED INSTALLATION
Option 1
(Return/Return Method)
1. Furnace blower must operate when ventilation from ERV is
required. The furnace should be set to run continuously or
interlocked with ERV.
2. A minimum separation of 1m (39") is recommended between
the two direct connections.
3. In order to prevent exhausting any fresh air, the ERV's exhaust
air connection should be upstream of the ERV's supply air
connection when ducting to the furnace's cold air return.
4. Weatherhood arrangement is for illustrative purposes only. 3m
(10') minimum separation and 460mm (18") above grade is
recommended.
5. Due to the differences in pressure between the ERV and the
equipment it is being connected to, the ERV’s airflow should be
balanced on site, using the procedure found in section
"AIRFLOW BALANCING".
NOTE: In the case of a sim-
plified installation, Option 1
is recommended.
Example only – duct configuration may differ depending on the model.
Stale air coming from different areas of the
house (ie bathroom, kitchen).
* Unit air flow should be balanced while ERV is on "High" speed and fur-
