2.4 I D
NSTALLING THE UCTWORK AND THE
Never install a stale air exhaust register in a room where there is a combustion device, such as a furnace, gas
water heater, fi replace or any appliance or equipment that can generate gaseous contaminants, or pollutants.
The negative pressure this could create in the room may impair proper evacuation of the gas or pollutants,
which may have severe health consequences.
If ducts have to go through an unconditioned space (e.g.: attic), always use insulated ducts to prevent condensation
formation inside and outside ducts, which could cause material damage and/or mold growth. Moreover, if
fresh air to building duct and/or stale air from building duct goes/go through an unconditioned space, the unit
must be set to operate continuously in cold conditions (below 10°C/50°F). Continuous air movement inside
ducts will prevent condensation formation. The unit can be stopped temporarily for maintenance and/or repair
purposes in such conditions.
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) is available for houses where there is no bathroom fan.

produced: kitchen, bathrooms, laundry room, etc.
• Install registers on an interior wall, 6 to 12 inches away from
the ceiling OR in the ceiling.
• Install the kitchen register at least 4 feet away from the range.
• Bathroom fans and range hoods can be used to better exhaust
stale air.
• Homes with more than one level require at least one exhaust
register at the highest level.
F :
RESH AIR TO BUILDING
• Install registers in bedrooms, dining room, living room and
basement.
• Install registers in the ceiling OR high on the walls with the

Duct connection to the central forced-air system can be regulated by some codes and standards. It is your
responsibility to consider and comply with your local requirements to avoid any non-compliance.
Do not connect the unit to any forced air system distribution duct.
S :
TALE AIR FROM BUILDING
Same as for Fully Ducted System, described on point 2.4.1.
F :
RESH AIR TO BUILDING
• Connect the fresh air distribution duct of the unit to the central
forced-air system return duct at least 10 feet away from the
central forced-air system (A+B)*.
* This 10-ft. distance applies only in areas where the outside
temperature falls below the freezing point 0°C (32°F).
NOTE: It is recommended, but not essential that the central forced-
air system blower runs when the unit is in operation.
NOTE: A home with multiple forced air systems should have one
unit on each system.
