4.0 Typical Installations
4.1 Fully Ducted System
4.2 Exhaust Ducted System
(Source Point Ventilation)
(Primarily for homes with radiant hot water or electric baseboard heating.
See Figure 4.)
Moist, stale air is exhausted from the high humidity areas in the
home, such as bathrooms, kitchens and laundry rooms.
Fresh air is supplied to bedrooms and principal living areas.
The use of bathroom fans and range hood is required to better exhaust
stale air.
Homes with more than one level require at least one exhaust register
at the highest level.
(For homes with forced air heating. See Figure 5.)
Moist, stale air is exhausted from the high humidity areas in the home,
such as bathrooms, kitchen and laundry room.
Fresh air is supplied to the cold air return or the supply duct of the
furnace.
The use of bathroom fans and range hood is required to better exhaust
stale air.
Homes with more than one level require at least one exhaust register at
the highest level.
NOTE: For this type of installation, it is not essential that the furnace
blower runs when the unit is in operation, but we recommend it.
