6.5.3 Simplified installation (Volume Ventilation) (as illustrated in Section 5.3)

There are two methods (figures 12 and 13) for connecting the unit to the furnace:

Method 1: return-supply Method 2: return-return

Stale air intake:

• Cut an opening into the furnace return duct (not less than 10 feet (3.1 m) from the

furnace (A+B)).

• Connect this opening to the stale air intake port on the HRV/ERV as shown .

Fresh air distribution: (same instructions as for Method 1 or Method 2, Section 6.5.2).

For method 2 (return-return) make sure there is a distance of at least 3 feet (0.9 m) between

the 2 connections to the furnace.

NOTE: For Method 1, it is not essential to synchronize the furnace blower operation

with the HRV/ERV operation, but we recommend it.

CAUTION

When performing connection to the furnace ducts (Method 1), these ducts must be sized to

support the additional airflow produced by the HRV/ERV. Also, the supply duct must be a steel

duct with a backdraft damper to prevent the risk of overheating HRV/ERV.
