1. T YPICAL INSTALLATIONS

Use the following illustrations as guidelines to help you decide on how the unit will be installed.

All the units should be hung from the joists.

In every case, bathroom fans and a range hood could be used to exhaust stale air. However, please note that an optional bathroom

installation kit (no. IKBV1000 for Venmar units and no. IKBB1000 for Broan units) is available for house where there is no bathroom fans.

Also, for homes with more than one level, we recommend one exhaust register at the highest level.

There are 3 installation methods: Fully Ducted System, Central Draw Point and Simplified Installation.

NOTE: An electrical outlet has to be available within 3 feet of the unit.

1.1 FULLY DUCTED SYSTEM (PRIMARILY FOR HOMES WITH RADIANT HOT WATER OR ELECTRIC BASEBOARD HEATING)

VH0088

Stale air coming from the register located at the highest level of the

house is exhausted to the outside. Fresh air from outside is filtered and

supplied by the register located in the lowest liveable level.

Homes with more than one level require at least one exhaust register at

the highest level.

See figure at right.

1.2 CENTRAL DRAW POINT (CONNECTION TO A FORCED AIR SYSTEM)

VH0089

Stale air coming from the register located at the highest level of the

house is exhausted to the outside. Fresh air from outside is filtered and

supplied to the return (plenum) or the supply duct of the forced air unit.

See figure at right.

For this type of installation, it is not essential that the forced air system

blower runs when the unit is in operation, but we recommend it.

NOTE: Home with multiple forced air systems should have one unit on

each system.

1.3 SIMPLIFIED INSTALLATION (CONNECTION TO A FORCED AIR SYSTEM)

VH0090

Stale air is exhausted to the outside. Fresh air from outside is filtered and

supplied to the return (plenum) or the supply duct of the forced air unit.

See figure at right.

To avoid cross-contamination and achieve the highest efficiencies, the

forced air system blower must always be ON.

NOTE: Home with multiple forced air systems should have one unit on

each system.

Do not connect the unit to any forced air system supply

duct.

CAUTION

Do not connect the unit to any forced air system supply

duct.
