Installation Methods

The Three Methods of Installation

The three methods of installation for the HRV system are the Simplified, Partially Dedicated and Fully Dedicated Installations. Refer to the installation illustrations in this manual.

Simplified Installations

The Simplified Installation draws stale air from the cold air return duct of the air handler/furnace and introduces an equal amount of fresh air farther downstream into the cold air return. Refer to "The Simplified Installation" in this manual.

The air handler/furnace blower must be running when the unit is operating for this system to be effective. Refer to "Interlocking HRV Operation to an Airhandler/Furnace Blower".

Partially Dedicated Installations

The Partially Dedicated Installation draws stale air from specific points in the house and introduces an equal amount of fresh air into the cold air return. Refer to "The Partially Dedicated Installation" in this manual.

Stale air ducts should be installed where the worst air quality problems occur (bathroom, kitchen, and laundry room). Each location with a stale air duct should have a timer which will initiate high speed ventilation. Refer to "Optional Timers" in this manual.

The air handler/furnace blower should be running when the HRV is operating to evenly distribute the fresh air throughout the house. Refer to "Interlocking HRV Operation to an "Airhandler/Furnace Blower".

Fully Dedicated Installations

The Fully Dedicated Installation draws stale air from specific points in the house and introduces an equal amount of fresh air to specific locations of the house. This system is not connected to an air handler/furnace. Refer to "The Fully Dedicated Installation" in this manual.

Stale air ducts should be installed where the worst air quality problems occur (bathroom, kitchen, and laundry room). Each location with a stale air duct should have a timer which will initiate high speed ventilation. Refer to "Optional Timers" in this manual.

Fresh air ducts should be installed to all bedrooms and living areas, excluding bathrooms, kitchen and utility areas. Grilles should be located high on a wall or in ceiling locations. Grilles that diffuse the air comfortably such as the Round Diffuser are recommended. If the floor is the only option available, then special care should be taken in locating grilles. Areas such as under baseboard heaters will help to temper the air. Also, optional inline duct heaters are available for mounting in the supply duct work to add heat if required.

Applications such as greenhouses, atriums, swimming pools, saunas, etc. have unique ventilation requirements which should be addressed with an isolated ventilation system.

Air Duct Design and Installation

A well designed and installed ducting system will allow the HRV to operate at its maximum efficiency.

Always try to keep duct runs as short and straight as possible. See Installation Diagrams for various installation options.

The inner and outer liners of the flexible insulated duct must be clamped to the sleeve of the weatherhoods (as close to the outside as possible) and the appropriate port on the HRV. It is very important that the fresh air intake line be given special attention to make sure it is well sealed. A good bead of high quality caulking (preferably silicone sealant) will seal the inner flexible duct to both the HRV port and the weatherhood prior to clamping with a large zip tie.

To minimize air flow restriction, the flexible insulated duct that connects the two outside weatherhoods to the HRV should be stretched tightly and be as short as possible.

Twisting or folding the duct will severely restrict air flow.

Installing the Ducting Between the HRV & Living Areas in the House

To maximize airflow in the duct system, all ducts should be kept short and have as few bends or elbows as possible. Forty-five degree elbows are preferred to 90° elbows. Use “Y” tees instead of 90° elbows whenever possible.

All duct joints must be fastened with screws, rivets or duct sealant and wrapped with mastic or a quality duct tape to prevent leakage. Mastic is preferred but if duct tape is used, we recommend aluminum foil duct tape.

Galvanized ducting from the HRV to the living areas in the house is recommended whenever possible, although flexible duct can be used in moderation if necessary.

To avoid possible noise transfer through the duct system, a short length (approximately 12 inches or 300mm) of non-metallic flexible insulated duct should be connected between the HRV and the supply/exhaust duct system.

The main supply and return lines to/from the HRV must be 6 inches (150mm) minimum. Branch lines to the individual rooms may be as small as 4 inches (100mm), but 5 inch (125mm) lines are preferred .

All ducts running through attics and unheated spaces must be sealed and insulated to code.

WARNING

Include a short length of fabric, flex duct or other non-metallic connector in the “Fresh Air to Building” hard ducted line in order to keep the HRV separately grounded (electrically) from the air handler. This will avoid a possible shock hazard to service people if a short to ground develops in one of the devices.
