5. FINDING A SUITABLE INSTALLATION AREA FOR HRV
The HRV unit should be installed in a mechanical room or as close to an outside wall as possible. This would assure a short run of
insulated flexible duct.
The HRV unit must always be installed in an area where the air is tempered to avoid freezing of the condensate line. The contractor
should install the unit in an area that is very accessible to allow the homeowner easy access for maintenance.
It is very important to install an electric receptacle (115v) near the HRV, a separate circuit breaker is also recommended. You should have
access to a condensate drain near the HRV to avoid the use of condensate pump.
3. TYPES OF INSTALLATIONS (CONTINUED)
EXHAUST AND
SUPPLY IN THE
RETURN
When using this application make
sure that there is minimum 3 feet
(0.9 m)between the fresh air and
exhaust air connections of the
HRV in the return air duct.
(see figure 3.3)
Make sure when using this
application that your fresh air
duct connection to the forced air
system return air duct is not less
than 10ft (3 m) upstream of the
return plenum connection to the
forced air system. Check with
your local code or the forced air
system’s manufacturer. The HRV
and forced air system must be
in continuous mode, to achieve
maximum comfort and to avoid
cross-contamination.
NOTE TO INSTALLER:
Dwellings with multiple forced
air systems requires one HRV
per system.
Insure the unit runs in
conjunction with forced air
system (Ref. wiring diagram for
furnace interlock)
figure 3.3
* For minimum distance between return and forced
air system, check with your local building codes
and forced air system manufacturer.
IMPORTANT:
Building and combustion
appliance installation codes do not allow return
air grilles or openings such as "breather tee" or
indirect connections in an enclosed room that is
susceptible to spillage of combustion appliances.
IMPORTANT: For optimal performance of your HRV, the installation of an optional 6" round galvanized backdraft damper is required on the fresh air to
home duct work. When performing duct connections, always use approved tools and material. Also use steel duct connections for these type of installs.
