The exhaust outlet and fresh air inlet on the outside of the
building should be at least ten (10) feet apart to avoid
cross contamination.
The Outdoor fresh air inlet must be located a minimum
of 10 feet from any other exhaust vent, gas meter,
outdoor grill, or source of open flame.
Fresh air inlets must also be located a minimum of ten
(10) feet from oil tank fill tubes, garbage cans and any
other source of contamination. Fresh air inlet and outlets
should not be installed in areas of stagnant air. Fresh air
inlet and outlet hoods should be located a minimum of
twelve (12) inches above the normal snow level.
CAUTION
!
Failure to follow installation instructions may lead to
premature failure of the heat transfer core.
The ERV fresh air inlet and return air grilles must not be
located in the same room as an indoor swimming or
exercise "lap" pool.
Determine outlet locations. Cut correct size hole. Cut a
short piece of 6" round duct to connect to the fresh air inlet
and exhaust air outlet hoods. For Model *ERVR100 or
*ERVR200. Use 8" round duct for Model *ERVR300.
Secure duct to inlet and outlet hood duct collars with
installer supplied fasteners. Install hood and ductwork
through penetration. See figure 13 for sealing duct
penetration and duct collar.

DUCTWORK CONNECTING ERV TO INDOOR
TERMINATION POINTS
CAUTION
!
Failure to follow this installation instruction may result in
property damage from sweating ductwork.
Insulate all connecting ductwork from the ERV to any
indoor termination point that will be subject to forming
condensation. Flexible or metal duct may be used.
An ERV can be applied either with an independent free
standing fresh and return air duct system or the fresh air
supply can be connected to the cooling and heating system
return air duct. The following guidelines should be consid-
ered when applying and installing either duct system.
FRESH AIR DUCT CONNECTION TO THE COOLING AND
HEATING SYSTEM RETURN AIR DUCT
The Fresh Air Supply duct from the ERV should be
connected a minimum of three (3) feet up stream of the
indoor unit return plenum. (See Figure 7)
A connection closer than three 3 foot may result in unbal-
anced airflow. Use a minimum of 5 foot section insulated
flexible duct to connect the ERV port labeled “Fresh Air To
Inside” to the return air duct.
FREE STANDING DUCT SYSTEM
For free standing ERV duct systems one or two fresh air
grilles located in a central part of the house will provide
effective distribution of the fresh air into the home par-
ticularly when the air to be exhausted from the home is
returned from several points. Use a minimum of 5 foot
