1.Ventilation Needs
A. Room count calculation
Determine your
ventilation needs
installation
How much fresh air do I need? Good air
quality is based in part on the capacity
of the home’s ventilation system.
Usually, the HRV’s or ERVs capacity is
measured in CFM (cubic feet per
minute) or L/s (Liters per seconds) of
fresh air being distributed in the living
space. The room count calculation or the
air change per hour method shows you
how to determine your ventilation needs.

supply and the exhausting
of stale air accumulated
in the home.
It is recommended to install
fresh air grilles in all
bedrooms and living areas. Exhaust
the stale air from the bathroom,
kitchen and laundry room.
1 CFM = 0.47189 L/s
1 L/s = 3.6 m3/hr
B. Air change per hour method
TOTAL cu ft x 0.35 per hr = total
Take total and divide by 60 to get CFM
Example:
25' x 40' house with basement
1,000 sq. ft. x 8' high x 2 (1st floor + basement) = 16,000 cu. ft.
16,000 cu. ft. x 0.35 ACH = 5,600 cu. ft.
5,600 cu. ft./60 minutes = 93 CFM
93 CFM is your ventilation need

2. Types of Installation (continued)
Exhaust at the
source and supply
in the return
There are different practices used to combine HRV or ERV to a forced air system.
Exhaust at the source
installation
This application uses a
devoted duct system for the
exhausting of stale air accumulated
in the home. The fresh air is dumped into
the return air duct and is distributed thru
the home by the existing supply air
ductwork of the forced air system.
Make sure when using this application that
your fresh air duct connection to the forced
air system return air duct is at least 3' from
the forced air system. You should check
with your local code or the forced air
system’s manufacturer.

HRV/ERV
Forced Air System
* For minimum distance between return and forced air
system, check with your local building codes and forced
air system manufacturer.
Indirect Connection - Breathing Tee
A Breathing Tee is a ventilation air supply
duct with an open tee located before the
connection to the return air duct. It allows
the HRV to function without supply air flow
rates being affected by the forced air
system’s fan speed.
Leaving a gap in the ventilation air supply
duct in place of the breather tee is
acceptable but not recommended.
Indirect Connection - Return Air Grille
With the return air grille approach, HRV or
ERV ventilation supply air is “dumped” near
a grille (between 4" and 12") in the return
air duct upstream of the recirculation fan.
4" to 12" maximum
*See your local code before making an installation.

Figure 3.1 Pull out the inserts first then use the straps to lift the unit out of the box.
Figure 3.2 Installation kit is shipped inside the unit.
Figure 3.3 Installation kit.
4. Finding a suitable installation area for HRV or ERV
The HRV or ERV units 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 or ERV 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 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 or ERV, a separate
circuit breaker is also recommended. You should have access to a condensate drain near
the HRV or ERV to avoid the use of condensate pump.
