3.6.2 CENTRAL DRAW POINT SYSTEM (AS ILLUSTRATED IN SECTION 2.2)

Stale air exhaust ductwork

Same as for Fully Ducted System, described on point 3.6.1.

Fresh air distribution ductwork

!WARNING

When performing duct connections, always use approved tools and materials. Respect all corresponding laws and safety regulations. Please refer to your local building code.

CAUTION

When performing duct connections to the furnace supply duct, this duct must be sized to support the additional airflow produced by the HRV/ERV. Also, use a steel duct. It is recommended that the HRV/ERV is running when the furnace is in operation to prevent backdrafting inside HRV/ERV.

There are 2 methods for connecting the unit to the furnace/air handler:

Method 1: Supply side connection

•Cut an opening into the furnace supply duct at least 18 inches (0.5 m) from the furnace/air handler.

•Connect this opening to the Fresh air to building port of the HRV/ERV (use steel

duct, see figure beside).

STEEL DUCT

•Make sure the HRV/ERV duct form an elbow inside the furnace/air handler ductwork.

•If desired, interlock (synchronize) the furnace/air handler blower operation (see Section 5).

MINIMUM 18”

(0.5 M)

Method 2: Return side connection

•Cut an opening into the furnace return duct not less than 10 feet (3.1 m) from the furnace/air handler (A+B).

•Connect this opening to the Fresh air to building port of the HRV/ERV (see figure beside).

NOTE: For Method 2, it is not essential that the furnace/air handler runs when the unit is operation, but we recommend it. If desired, interlock (synchronize) the furnace/air handler blower operation (see Section 5).
