A properly designed ducting system will allow the ERV to operate at its maximum efficiency. (Air flow
will be restricted by undersized ducting, use of too many elbows, tees, bends, etc.). Always try to
keep duct runs as short and straight as possible.
All joints must be airtight, sealed and impervious to moisture. See
Dimensional Drawings for each
unit for exact duct sizes and location.
To minimize pressure drop and noise, galvanized metal ducts, properly sized, are recommended.
Keep ducting as short as possible and use a minimum of elbows and tees.
Connecting sections and shorter runs may be flexible ducting one size larger than the metal
equivalent. Use flexible duct connectors at the ERV to avoid noise transmission.
All duct joints must be secured with screws, rivets or duct sealant and sealed with aluminum duct
tape to prevent leakage.
Attention
•
Flexible duct connectors should be installed between the HRV and the galvanized ductwork.
•
Use fully insulated ducting with an integral vapour barrier on all runs that pass through unheated areas to
avoid condensation problems and energy losses from the air streams. Consult local codes.
