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 pressure. After installation, the compatibility of the two pieces of equipment must be conrmed
by measuring the airow of the Fresh Air Applliance using the balancing procedure found in this manual.
It is always important to assess how the operation of any FAA may interact with vented combustion equipment (i.e.
Gas Furnaces, Oil Furnaces, Wood Stoves, etc.)
Products are designed and manufactured to provide reliable performance, but they are not guaranteed to be 100%
free of defects. Even reliable products will experience occasional failures, and this possibility should be recognized
by the user. If these products are used in a life support ventilation system where failure could result in loss or injury,
the user should provide adequate back-up ventilation, supplementary natural ventilation or failure alarm system, or
acknowledge willingness to accept the risk of such loss or injury.
Your ventilation system should be installed in accordance with the local building code that is in effect, in absence
of such requirements, it is recommenced to check with local authorities having jurisdiction in your area prior to

INSTALLATION EXAMPLES
The way your heat/energy-recovery ventilator is installed can make a significant difference to the electrical
energy you use. To minimize the electricity use of the heat/energy-recovery ventilator, a stand-alone fully
ducted installation is recommended. If you choose a simplified installation that operates your furnace air
handler for room-to-room ventilation, an electrically efficient furnace that has an electronically commutated
(EC) variable speed blower motor will minimize your electrical energy consumption and operating cost.
Example only – duct configuration may differ depending on the model.
FULLY DEDICATED SYSTEM
BEST FOR NEW CONSTRUCTION
1. Stale air is drawn from
key areas of the home
requiring local exhaust
(bathroom, kitchen,
laundry room).
2. Fresh air is distributed
directly to habitable
rooms in the house
(bedrooms, living room)
3. The FAA’s airflow must
be balanced after
installation using the
procedure found in the
section “AIRFLOW
BALANCING”
Suggested installation for:
• Hydronic baseboard
• Inoor heating
• Electric baseboard
• Mini split heat pump
Benets: Provides the best
fresh air distribution in the
house; lowest operation cost
since the furnace/air handler
unit is not needed.

conditioners)
• When ducting fresh air to
living area is not possible or
practical, i.e. expensive or
when the central AHU will
operate year-round.
Benets: Conditions the fresh
air prior to
distributing it throughout the
house
1. In order to provide proper distribution of the fresh air, it is
recommended that the furnace blower be set to run continuously or
interconnected with FAA. See furnace electrical connection on page
16.
2. Stale air is drawn from key areas of the home (bathroom, kitchen,
laundry room).
3. Fresh air is supplied to the return air plenum of the furnace.
4. Due to the difference in pressure between the FAA and the equipment
it is being connected to the FAA's airflow must be balanced on site,
using the procedure found in the section “AIRFLOW BALANCING”
* In the case of a multi-zone system, please contact Fantech customer

Make sure the FAA is
capable of meeting the
required airow rate.
Fantech fresh air appliances (FAA) that use a supply fan shutdown for frost prevention do
not include an outdoor air motorized damper. If you are using a simplied installation, i.e.
connecting the FAA supply air duct to a furnace's return air duct, the FAA must operate
continuously. When the FAA is turned off, no warm exhaust air will ow through the FAA
but the furnace's fan will continue to draw in outdoor air directly into the furnace. If it's
cold outside, cold air will be introduced, without re-heating, directly into the furnace.
If the FAA is installed such that the homeowner may turn off the FAA during the winter, we
recommend installing a motorized damper between the FAA's supply air and the furnace's
return air duct that closes when the FAA is not operating. To install a damper accessory to
the product, locate the auxiliary connector on the side of the electrical box. See Figure 1.
Using the included wire harness, connect the damper accessory to the product. Figure 1

1. Furnace blower must operate when ventilation from FAA is required. The furnace should
be set to run continuously or interlocked with FAA. See furnace electrical connection
on page 16.
2. A minimum separation of 1m (39’’) is recommended between the two direct
connections.
3. In order to prevent exhausting any fresh air, the FAA's exhaust air connection should be
upstream of the FAA's supply air connection when ducting to the furnace’s cold air return.
4. Due to the difference in pressure between the FAA and the equipment it is being
connected to the FAA's airflow must be balanced on site, using the procedure found in the

EXTERIOR DUCTING INSTALLATION
WEATHERHOOD LOCATION
• Decide where your intake and exhaust hoods will be located.
Locating the Intake Weatherhood
• Should be located upstream (if there are prevailing winds) from the
exhaust outlet.
• At a minimum distance to 900 mm (3') away from dryer vents and furnace
exhaust (medium or high efficiency furnaces), driveways, oil fill pipes, gas
meters, or garbage containers.
• At a minimum height of 460mm (18’’) above the ground, or above the level
of expected snow accumulation.
• Ideally, keep weatherhoods 1m (3') from corners.
• Do not locate in the garage, attic, crawl space, or underneath deck.
Locating the Exhaust Weatherhood
• At least 460mm (18") above ground or above the depth of expected snow accumulation
• Ideally, keep weatherhoods 1m (3') from corners.
• Not near a gas meter, electric meter or a walkway where fog or ice could create a hazard
• Do not locate in a garage, workshop or other unheated space
INSTALLING THE DUCTING TO THE WEATHERHOODS
A well designed and installed ducting system will allow the FAA to operate at its
maximum efficiency. The inner liner of the flexible insulated duct must be secured to the
sleeve of the weatherhood (as close to the outside as possible) and to the appropriate duct
connection on the FAA. The insulation should remain full and not crushed. The outer liner,
which acts as a vapor barrier, must be completely sealed to the outer wall and the FAA
using tape and/or caulking. A good bead of high quality caulking (preferably acoustical
sealant) will seal the inner flexible duct to both the FAA duct connection and the
weatherhood prior to securing them.
To minimize airflow restriction, the flexible insulated duct that connects the two outside
weatherhoods to the FAA should be stretched tightly and be as short as possible.
Twisting or folding the duct will severely restrict airflow.
See “Installation Diagram Examples” for installation examples.
1 Using the duct connection of
the outside hood, outline the
intake & exhaust holes to be
cut. The holes should be slightly
larger than the duct connection
to allow for the thickness of the
insulated flexible duct. Cut a
hole for both the intake and
exhaust hoods.
3 Push the hood into the opening
and then attach the hood to the
outside wall with mounting
screws.
Repeat the installation
procedure for both the supply
and exhaust hoods.
2 Pull the insulated flexible duct
through the opening until it is
well extended and straight.
Slide the duct’s inner vinyl sleeve
over the hood duct connection
and secure. Pull the insulation
over the duct and pull the vapor
barrier over the sleeve. Secure
with appropriate tape or
sealant.
4 Using a caulking gun, seal
around both hoods to prevent
any leaks.

INTERIOR DUCTING INSTALLATION
• To maximize airflow through the ductwork system, all ducts should be kept short and have as few bends or elbows as possible.
• 45º elbows are preferable to 90º.
• Use “Y“ ducts instead of “T” ducts whenever possible.
• All duct joints must be fastened with screws or duct sealant and wrapped with aluminum foil duct tape to prevent leakage.
• Galvanized ducting from the FAA to the living areas in the house is recommended whenever possible, although flexible ducting
can be used in moderation when necessary.
• To avoid possible noise transfer through the ductwork system, a short length (approximately 300 mm, 12’’) of nonmetallic flexible
insulated duct should be connected between the FAA and the supply/exhaust ductwork system.
• The main supply and return line to/from the FAA must have the same diameter as the duct connection or larger.
• Branch lines to the individual rooms may be as small as 100 mm (4’’).
Installing ducting to FAA
Warning: Always fix and secure the 6" collars with the screws supplied. Avoiding this critical step the unit will accumulate condensation.
Tip to Installer: To ensure a better installation and to avoid an undesired bend in the duct, align the duct with the collar before securing over the four
hooks.
The fresh air from outside and the Exhaust air to outside from the termination ducts to the FAA must be fully insulated of thermal insulation ducts to
minimize heat loss and gain. All tapes, mastics, and nonmetallic clamps used for field installation of flexible ducts shall be listed and labeled to Standard
UL 181B - Closure Systems for Use With Flexible Air Ducts and Air Connectors.
Air Connector A category of flexible duct not meeting the requirements of an Air Duct per UL 181 Standard (not tested for flame penetration, puncture
and impact) and having limitations on use, length and location as defined by NFPA 90A and 90B. Air Connectors are identified by a “round shape” listing
label of the listing agency.
Air Duct A category of flexible duct tested and classified as to the Surface Burning Characteristics in accordance with the UL 181 Standard. Air Ducts
are identified by a “rectangular shape” listing label of the listing agency.
To ensure quiet operation of ENERGY STAR qualified FAA, each product should be installed using sound attenuation techniques appropriate for the
installation. Once insulated flex is attached to the collar, slide collar in keeper section, fixed collar to the unit with four screws supplied in installation
kit to insure a proper seal.
Warning: To reduce air leakage in the final installation always seal the joint between all collars and keepers with aluminum tape or mastic.
Supply air grilles location
In homes without a forced air furnace, fresh air should be supplied to all habitable rooms, including bedrooms and living areas. It should be supplied
from high wall or ceiling locations. Grilles that diffuse the air comfortably are recommended. In homes with a forced air furnace, you may want to connect
the FAA to the furnace ductwork (see information below).
Exhaust air grilles location
The stale air exhaust system is used to draw air from the points in the house where the worst air quality problems occur. It is recommended that return
air ducts be installed in the bathroom, kitchen, and laundry room. Additional return air ducts from strategic locations may be installed. The furnace
return duct may also be used to exhaust from. In this method, the exhaust air is not ducted back from bathrooms, kitchens, etc to the HRV with
“dedicated lines”.
Insert vinyl duct over the hooks
and seal with a Tie wrap
Insert insulation inside the double
collar.
Finish by taping the vapor
barrier to the collar to insure
proper seal.
Slide collar on the unit. Fix and secure with four screws supplied
and seal all joints.
As per building codes and installation requirements for combustion appliances:
Air return ducts, or openings for air return, should not be placed in enclosed spaces containing combustion
appliances that are subject to spillage.
10
FAA INSTALLATION
LOCATION
The FAA must be located in a conditioned space where it will be possible to conveniently service the unit. Typically
the FAA would be located in the mechanical room or an area close to the outside wall where the weatherhoods will
be mounted. If a basement area is not convenient or does not exist, a utility room may be used.
Attic installation must meet the following conditions:
• Attic temperature must be above freezing conditions at all times and for best performance should be 12°C
(54 °F).
• The condensate drain (if included) must be installed so that the condensate drains and is protected from freezing.
• The attic is easily accessible for equipment maintenance and inspection.
Connecting appliances to the FAA is not recommended. These include:
• Clothes dryer
• Range top
• Stovetop fan
• Central vacuum system
• Bathroom exhaust fans unless they are specifically designed for this purpose
These appliances may cause lint, dust or grease to collect in the FAA, damaging the unit.
Connecting any of these types of appliances to the
FAA will void your warranty.
Mounting- Chain mount
• Have a nearby power supply
(120 volts, 60Hz)
• Choose a location which
allows the possibility
of mounting the unit to
supporting beams.
• The unit should be level
in order to allow proper
condensate drainage
• To minimize noise, do not
install unit in living area
• Ensure proper drainage
1 Place fastening hooks on
the strapping board or
the oor joists.
2 Take at screwdriver and
slightly pull on punched out
tab. Put chain link under
hook.
4 Install a spring on each
chain. Hook the spring
in the links so a loop is
created in the chain. The
spring will then support the
unit's weight and absorb
vibrations.
3 Hang the unit by slipping
a link onto the hanging
hooks, making sure the
unit is level.
11
INSTALLING DRAIN LINE
Insert the threaded drain adapter thru the bottom of the FAA and hand tighten the plastic nut, and with a wrench tighten the nut another half turn to assure a
better seal.
Install the condensate line (included in drain kit). Insert condensate tubing by pushing clear plastic line over drain adapter. Make condensate trap by
looping the clear plastic tubing. This procedure is to avoid foul odor to enter the FAA.
The drain nipple is placed upside down in the unit to prevent it being damaged during shipping or the installation of the unit.
The Switch on the electrical box is used to toggle between STANDBY, REDUCED speed and NORMAL speed modes.
Place the unit in NORMAL speed to perform the balancing.
Make a loop in condensate line, not be subject to
freezing temperatures.
Use a condensate pump if you don’t have access to a drain.
CAUTION
A Drain and Tubing (included) must be installed for all HRV units. For ERV units, drain is not required, however, it is recommended for
climates where outdoor temperatures typically remain below -25°C (-13°F) combined with an indoor relative humidity higher than 40%
for a period of 24 hours or serveral days in a row.

On some newer furnaces and older
thermostats, energizing the R and
G terminal at the furnace has the
effect of energizing the Y at the
thermostat and thereby turning on
the cooling system. If you identify this
type of thermostat, you must use the
“Alternate Furnace Interlock Wiring”

TROUBLESHOOTING
Problem Causes Solutions
Air is too dry Dehumidistat control is set too low Increase the desired level of humidity. Change ventilation mode from
continuous mode to standby.
FAA out of balance Have contractor balance FAA airows
Air is too humid Dehumidistat control is set too high Reduce the desired level of humidity. Combine this with the use of continuous
exchange mode.
Sudden change in temperature Wait until outside temperature stabilizes (winter). Heating will also improve
situation.
Storing too much wood for heating Store a majority of your wood outside. Even dried, a cord of wood contains
more than 20 gallons of water.
Dryer vent exhaust is inside home Make sure the dryer vent is exhausting outside.
Poor air circulation near windows Open curtains or blinds.
FAA out of balance Have contractor balance FAA airows
Well sealed basement door is closed Open the door or install a grill on the door.
Failed damper system may be stuck in recirculation
mode
Check defrost damper. If damper is always blocking incoming fresh air, have
contractor verify damper system.
Persistent condensation
on window
Improper adjustment of dehumidistat control Reduce the desired level of humidity. Combine this step with use of continuous
exchange mode.
FAA out of balance Have contractor balance FAA
Poor air circulation near windows Open curtains or blinds.
Poor Air Flows 1/4" (6mm) mesh on the outside hoods is plugged Clean exterior hoods or vents
Filters plugged Remove and clean lter
Core obstructed Remove and clean core
Indoor grilles closed or blocked Check and open grilles
Inadequate power supply at site Have electrician check supply voltage
Ductwork is restricting airow Check duct installation
Improper speed control setting Increase the speed of the FAA (i.e. change unit control from REDUCED to NORMAL
speed)
FAA airow improperly balanced Have contractor balance FAA airows
Ducting has fallen down or been disconnected from FAA Have contractor reconnect ducting
Supply air feels cold Poor location of supply grilles, the airow may irritate
the occupant
Locate the grilles high on the walls or under the baseboards, install ceiling
mounted diffuser or grilles so as not to directly spill the supply air on the
occupant (eg. Over a sofa)
Turn down the FAA supply speed. A small duct heater (1kw) could be used to
temper the supply air
Placement of furniture or closed doors is restricting the movement of air in
the home
Outdoor temperature extremely cold If supply air is ducted into furnace return, the furnace fan may need to run
continuously to distribute ventilation air comfortably
FAA and/or Ducts frosting up FAA air ows are improperly balanced Have HVAC contractor balance the FAA airows
Malfunction of the FAA defrost system Note: minimal frost build-up is expected on the core before unit initiates
defrost cycle functions
Condensation or Ice Build Up in
Insulated Duct to the Outside
Incomplete vapor barrier around insulated duct Tape and seal all joints
A hole or tear in outer duct covering Tape any holes or tears made in the outer duct covering
Ensure that the vapor barrier is completely sealed.
LED is ashing Everything is in good operations
LED is not ashing No Power is being transmitted to the Control Board Make sure unit is plugged.
Transformer may need replacing.
Note: It is best to get the unit checked by a certied HVAC Contractor/Technician.

VEUILLEZ LIRE ET CONSERVER CES INSTRUCTIONS
Avant de procéder à l’installation, examinez avec soin la façon dont le système fonctionnera s’il est relié à tout
autre appareil mécanique, notamment une fournaise à air pulsé ou un appareil de traitement d’air dont la pression
statique est plus élevée. Une fois l’installation terminée, la compatibilité des deux appareils doit être conrmée en
mesurant le débit d’air du appareil à air frais (AAF) au moyen de la procédure d’équilibrage du présent manuel. Il
importe de toujours évaluer l’interaction du AAF avec les appareils de chauffage à évacuation
(fournaise à gaz, fournaise à mazout, poêle à bois, etc.)
Les produits sont conçus et fabriqués pour fournir une performance able, mais ils ne sont pas garantis à 100%
