3. INSTALLATION (CONT’D)
3.6 INSTALLING THE DUCTWORK AND REGISTERS (CONT’D)
3.6.2 SIMPLIFIED INSTALLATION (AS ILLUSTRATED IN SECTION 2.3)
There are 2 methods for connecting the unit to the furnace/air handler:
Method 1: Supply-return connection Method 2: Return-return
Stale air intake:
• Cut an opening into the furnace/air handler return duct not less than 10 feet from the furnace/air handler (A+B).
• Connect this opening to the Exhaust air from building port of the HRV/ERV.
Fresh air distribution:
• Same instructions as for Method 1 or Method 2, Section 3.6.2.
For Method 2 (Return-return), make sure there is a distance of at least 3 feet between the 2 connections to the furnace/air
handler.
NOTE: For Method 1, it is not essential to synchronize the furnace blower operation with the unit operation, but we recommend it.
WARNING
When performing duct connections, always use approved tools and materials. Respect all corresponding laws and/or 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. For a Return-Return installation, the furnace blower must be in operation
when the HRV/ERV is in operation.
