TO BE COMPLETED BY CONTRACTOR AFTER INSTALLATION
CAUTION
Before
installation, careful consideration must be given to
how this system will operate if connected to any other piece
of mechanical equipment, i.e. a forced air furnace or air
handler, operating at a higher static. After
installation, the
compatibility
of the two pieces of equipment must be
confirmed by measuring the airflow’s of the Heat Recovery
Ventilator (HRV) Energy Recovery Ventilator (ERV) by
using the balancing procedure found in this manual.
It is always important to assess how the operation of any
HRV/ERV may interact with vented combustion equipment
(ie. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.).
NEVER install a ventilator in a situation where its normal
operation, lack of operation or partial failure may result
in the backdrafting or improper functioning of vented
combustion equipment!!!

Introduction
These Heat Recovery Ventilators (HRVs) are designed
for commercial and industrial applications to provide
fresh air to a building while exhausting an equal
amount of stale air. During the winter months the
incoming cold fresh air is warmed by utilizing the heat
recovered from the stale air before it is exhausted to
the outdoors. During summer months when the indoor
space is air conditioned, the Heat Recovery Ventilator
will help in cooling the incoming fresh air with the stale
air that is being exhausted.

Selecting the Correct Size HRV
Commercial and Institutional Requirements
For outdoor air requirements, ASHRAE has produced the Ventilation Standard 62-1989
that is used to determine acceptable ventilation rates. This standard is referenced directly or
used as “Good Engineering Practice” in most Code documents or design criteria.
