Note| Warning/ Important note| Information| Technical information| Practical tip

This product earned the ENERGY STAR® by meeting strict energy efficiency guidelines set by Natural Resources Canada and the US EPA. This product meets ENERGY STAR requirements only when used in Canada.
To ensure quiet operation of the ENERGY STAR certified H/ERV, each product model must be installed using sound attenuation techniques appropriate for the installation.
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 forced air system for room-to-room ventilation, an electrically efficient system that has an electronically commutated (EC) variable speed blower motor will minimize your electrical energy consumption and operating cost.

Installation of a user-accessible control with your product model will improve comfort and may significantly reduce the product model’s energy use.

PLEASE READ AND SAVE THESE INSTRUCTIONS

For residential use only

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 confirmed by measuring the airflow of the Fresh Air Appliance (FAA) 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 theuser. 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 installing this product.

INSTALLATION TYPES

Example only – duct configuration may differ depending on the model.

FAA DUCTING FOR FULLY DEDICATED SYSTEM

BEST

1. Stale air is drawn from areas requiring local exhaust (bathroom, kitchen, laundry room).
2. Fresh air is distributed to habitable rooms (bedrooms, living room)
3. The FAA’s airflow must be balanced after installation using the procedure found in the section “AIRFLOW BALANCING.”

Suggested 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 forced air system is not needed.

Make sure the FAA is capable of meeting the required airflow rate.

FAA/FORCED AIR SYSTEM DUCTING FOR PARTIALLY DEDICATED SYSTEM

BETTER

1. Forced air system blower must operate when ventilation from FAA is required. The system should be set to run continuously or interlocked with FAA. See forced air system electrical connection.
2. Stale air is drawn from areas requiring local exhaust (bathroom, kitchen, laundry room).
3. Fresh air is supplied to the return air plenum of the forced air system.
4. Before operation, the FAA’s airflow must be balanced on site. For this, use the procedure found in the section “AIRFLOW BALANCING”. During the balancing procedure, make sure the forced air system blower is running and the FAA is running at “Normal” speed.
5. In the case of a multi-zone system, please contact Fantech customer service prior to installing any installation type requiring the use of the forced air system interlock.
6. The FAA should only be paired with one forced air system. In the case where there are more than one forced air system please contact Fantech customer service prior to making a product selection.

Suggested for:

• Forced air system (central furnace or central air conditioner)
• When ducting fresh air to living area is not possible or practical, i.e. expensive or when the forced air system will operate year-round

Benefits:
Conditions the fresh air prior to distributing it throughout the house.

FAA/FORCED AIR SYSTEM FOR SIMPLIFIED INSTALLATION

GOOD

1. Forced air system blower must operate when ventilation from FAA is required. The system should be set to run continuously or interlocked with FAA. See forced air system electrical connection.
2. Stale air is drawn from areas requiring local exhaust (bathroom, kitchen, laundry room).
3. Fresh air is supplied to the return air plenum of the forced air system.
4. Before operation, the FAA’s airflow must be balanced on site. For this, use the procedure found in the section “AIRFLOW BALANCING”. During the balancing procedure, make sure the forced air system blower is running and the FAA is running at “Normal” speed.
5. In the case of a multi-zone system, please contact Fantech customer service prior to installing any installation type requiring the use of the forced air system interlock.
6. The FAA should only be paired with one forced air system. In the case where there are more than one forced air system please contact Fantech customer service prior to making a product selection.

Suggested for:

• When bathroom and kitchen already have local exhaust system
• May be suitable for retrofitting

Benefits:
Least expensive installation type

INSTALLING THE OUTDOOR VENTS

RECOMMENDED INSTALLATION

Intake

• Should be located upstream of prevailing winds from exhaust

• At a minimum 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.

• Do not locate in the garage, attic, crawl space, or underneath deck.
  Locating the Exhaust Weatherhood

• 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 VENTS

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 hood (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 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.

1. Cut hole between wall studs

2. Insert vent

3. Secure vent with proper screws

4. Seal using outdoor rated caulking

5. Attach insulated duct from inside and tape

DUCT INSTALLATION

CONNECTING THE DUCTS TO THE FAA

Do not handle unit by the collars / collar openings to avoid damaging the collars & foam insulation

• 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.
• 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 100mm (4’’).

INSTALLING DUCT TO FAA
Position a 12″ (300mm) section of nonmetallic flexible duct onto duct collar. Using (1) cable tie, attach flexible ducting with the correct FAA duct collar.
SUPPLY AIR GRILLES LOCATION
Without a forced air system: fresh air should be supplied to all habitable rooms from high wall or ceiling locations. Grilles that diffuse the air comfortably are recommended. With a forced air system: Connect to the system’s ductwork.
EXHAUST AIR GRILLE’S LOCATION
Draw stale air from the points where the worst air quality problems occur: bathroom, kitchen, and laundry room. Additional return air ducts from strategic locations may be installed. The forced air system 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 FAA with “dedicated lines”.

INSTALLING THE DRAIN

Install the drain hose making a “P” trap, secure the condensate line drain to FAA by sliding into
connection. Fill the condensate line with water

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.
