PLEASE READ AND SAVE THESE INSTRUCTIONS
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 higher static pressure. After installation, the compatibility of the two pieces of equipment must be confirmed by measuring the airflow of the Fresh Air Appliance 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 backup 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 recommended to check with local authorities having jurisdiction in your area prior to installing this product.

Bathroom: If the FAA is going to provide the required local exhaust ventilation for each bathroom with each a continuous 20 CFM (10 L/s), this ventilation rate can be considered as part of the whole-building ventilation rate.
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
- Stale air is drawn from key areas of the home requiring local exhaust (bathroom, kitchen, laundry room).
- Fresh air is distributed directly to habitable rooms in the house (bedrooms, living room)
- The FAA’s airflow must be balanced after installation using the procedure found in the section “AIRFLOW
FAA ducting for fully Dedicated System
- Ductwork layout may differ depending on model
- Unit air flow should be balanced while FAA is on “Normal” speed and the furnace blower is running.
Suggested installation for:
- Hydronic baseboard
- In-floor heating
- Electric baseboard
- Mini split heat pump
Benefits: Provides the best fresh air distribution in the house; lowest operation cost since the furnace/air handler unit is not needed.
DIRECT CONNECTION of the FRESH air to the living area to the RETURN PLENUM of the AIR HANDLER (Stale air drawn from key areas of the home)
PARTIALLY DEDICATED SYSTEM (BETTER)
- In order to provide proper distribution of fresh air, it is recommended that the furnace blower be set to run continuously or be interconnected with FAA. See furnace electrical connection on page 16.
- Stale air is drawn from key areas of the home (bathroom, kitchen, laundry room).
- Fresh air is supplied to the return air plenum of the furnace.
- 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 service prior to installing any installation type requiring the use of the furnace interlock”
FAA/Furnace ducting for Partially Dedicated System
- Ductwork layout may differ depending on model
Fantech fresh air applicance (FAA or HRV/ERV) that use a supply fan
shutdown for frost prevention do not include an outdoor air motorized damper.
If you are using a simplified 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 flow 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. See the wiring diagram (figure 1). You may also choose to use a
Fantech FAA that uses a recirculation defrost that incorporates an outdoor air
damper.
Suggested installation for:
- Central furnace (air handling unit or central air conditioners)
- When ducting fresh air to the living area is not possible or practical, i.e. expensive or when the central AHU will operate year-round.
Benefits: Conditions the fresh air prior to distributing it throughout the house
DIRECT CONNECTION of both the FAA SUPPLY AIR STREAM and EXHAUST AIR STREAM to the FURNACE COLD AIR RETURN
SIMPLIFIED INSTALLATION (GOOD)
(RETURN/RETURN METHOD)
- The 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.
- A minimum separation of 1m (39’’) is recommended between the two direct connections.
- 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.
- 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 service prior to installing any installation type requiring the use of the furnace interlock”
FAA/Furnace ducting for Simplified Installation – Option 1
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 simplified 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 flow 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. See the wiring diagram (figure 1).
You may also choose to use a Fantech FAA that uses a recirculation defrost
that incorporates an outdoor air damper.**
Suggested installation for:
- When the bathroom and kitchen already have a local exhaust system
- It May be suitable for retrofitting
Benefits: Least expensive installation type
EXTERIOR DUCTING INSTALLATION
REQUIRES A WEATHER HOOD WITH A BACKDRAFT DAMPER ON THE EXHAUST SIDE.
WEATHER HOOD LOCATION
- Decide where your intake and exhaust hoods will be located.
Locating the Intake Weather hood
- Should be located upstream (if there are prevailing winds) from the exhaust outlet.
- At a minimum distance of 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 weather hoods 1m (3′) from corners.
- Do not locate in the garage, attic, crawl space, or underneath the deck.
Locating the Exhaust Weather hood
- 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 weather hood (as close to the outside as
possible) and to the appropriate duct connection on the FAA. The insulation
should remain full and not be 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 weather hood 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.
STEPS FOR HOOD INSTALLATION:
-
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.
-
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 it. Pull the insulation over the duct and pull the vapor barrier over the sleeve. Secure with appropriate tape or sealant.
-
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.
-
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 the 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 agent.
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 agent.
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 the collar in the keeper section, fixed the collar to the unit with four screws supplied in the 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 the 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. In this method, the exhaust air is not
ducted back from bathrooms, kitchens, etc to the HRV with “dedicated lines”.
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.
FAA INSTALLATION
- Have a nearby power supply (120 volts, 60Hz)
- Choose a location that 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 the unit in the living area
- Ensure proper drainage
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
|
---|---
1 Place fastening hooks on the strapping board or the floor joists.| 2 Take a
flat screwdriver and slightly pull on the punched-out tab. Put chain link
under hook.
|
3 Hang the unit by slipping a link onto the hanging hooks, making sure the
unit is level.| 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.
The drain nipple is placed upside down in the unit to prevent it from being damaged during shipping or the installation of the unit.
If the outdoor air temperature is above 32°F (0°C) at the extract air (30%
RH/72°F, 30% RH /22°C), no drain line installation is required.
If this is the case keep the drain spout as shipped from the factory with
the cap.
The Switch on the electrical box is used to toggle between STANDBY, REDUCED
speed, and NORMAL speed modes.
Place the unit at NORMAL speed to perform the balancing.

ENTERING BALANCING MODE
In the options menu during the initial 5-second countdown sequence, long press
on the “ECO” area for 5 seconds to enter basic balancing mode. The supply and
exhaust fans are adjusted on high speed only and the offsets are
proportionally applied to the medium and low speed automatically.
| STAGE 1
(ADJUST THE LEVEL OF THE EXHAUST FAN AT HIGH SPEED):
• In this step, balance the exhaust fan and measure airflow on the exhaust air
side
• Pressing on “up” or “down” will adjust the fan speed in increments of 1%.
• Once the desired exhaust airflow is reached, press on “next” and move on to
the next stage.|
---|---|---
| STAGE 2
(BALANCE SUPPLY FAN ONLY IN HIGH SPEED):
• In this step, balance the supply fan and measure airflow on the supply air
side
• Pressing on “up” or “down” will adjust the fan speed in increments of 1%.
• Once happy with the outcome, press on
“Next” to complete balancing
• The supply and exhaust offset values will be proportionally applied to low
and medium speeds as well.|

WIRING DIAGRAM TO FURNACE
FOR A FURNACE CONNECTION TO A COOLING SYSTEM:
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 the type of thermostat, you must use the“Alternate Furnace Interlock Wiring”
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.
