Installation guide

Duct installation requirements for all blowers: °
All duct work materials (including screws and duct tape)
must be purchased separately by the customer. °
When planning new duct work, always look for the
shortest, most direct route to the outside. See page °
5 for examples.
You can increase the duct size over the duct run if °
desired. To prevent a back draft, never decrease the
duct size over the run.
Do not rely on duct tape alone to seal duct joints. °
Fasten all connections with sheet metal screws and
tape all joints with certified silver tape or duct tape.

Exhaust Knock-out Locations for Use with
REMP and ILHSF Series Blowers
Use sheet metal screws as required to support the duct
weight.
To prevent back-drafts, a damper at the duct outlet may
also be required.
Make sure duct work does not interfere with floor joists
or wall studs.
With concrete siab construction, “box-in” the duct work
and blower wiring to prevent collapsing or other dam-
age when the wet concrete is poured.
Cross-drafts or air currents from adjacent open win-
dows or doors, heating/air conditioning outlets, ceiling
fans and recessed ceiling lights reduce vent efficiency.
* System exhaust location (see page 6) must take
into account accumulated snowfall, where applicable.
