See Figure 4.)

Moist, stale air is exhausted from the high humidity areas in the home,
such as bathrooms, kitchens and laundry rooms.
Fresh air is supplied to bedrooms and principal living areas.

If required, bathroom fans and a range hood may be used to better
exhaust stale air.

Homes with more than one level require at least one exhaust register at
the highest level.

(For homes with forced air heating. See Figure 5.)

Moist, stale air is exhausted from the high humidity areas in the home,
such as bathrooms, kitchen and laundry room.

Fresh air is supplied to the cold air return or the supply duct of the
furnace.

If required, bathroom fans and a range hood may be used to better
exhaust stale air.
Homes with more than one level require at least one exhaust register at
the highest level.

NOTE: For this type of installation, it is not essential that the furnace

blower runs when the unit is in operation, but we recommend it.

• Inspect the exterior of the unit for shipping damage. Ensure that there is no damage to the door, door latches, door hinges,

dampers, duct collars, cabinet, etc.

• Inspect the interior of the unit for damage. Ensure that the fan motor assembly, recovery core, insulation, damper, damper

actuator and drain pan are all intact.

• If the unit was damaged during shipping, contact your local distributor. (Claim must be made within 24 hours after delivery.)

INSPECT THE CONTENTS OF THE BOX

Choose an appropriate location for the unit:

• Within a heated area of the house (10°C / 50°F or more), normally the basement
(in a furnace room, a laundry room, etc).

• Away from living areas (dining room, living room, bedroom), if possible.

• So as to provide easy access to the interior cabinet and to the control panel in
the unit.

• Close to an exterior wall, so as to limit the length of the insulated flexible duct to
and from the unit.

• Close to a drain. (If no drain is close by, use a pail to collect run-off.)

• Away from hot chimneys, electrical panel and other fire hazards.

• Allow for a power source (110 V standard outlet).

Hang the unit to ceiling joists with the 4 chains and springs
(See Figure 8).

4.1 LOCATING AND MOUNTING THE UNIT

Make sure the unit is level.

a)Follow the instructions in section 4.3 to determine the appropriate duct diameters for your system.
b)Keep it simple. Plan for a minimum of bends and joints. Keep the length of insulated duct to a minimum.
c)Do not use wall cavities as ducts. Do not use branch lines smaller than 4” Ø (102 mm Ø).
d)Do not ventilate crawl spaces or cold rooms. Do not attempt to recover the exhaust air from a dryer or range hood; this would cause

clogging of the recovery core. Use sheet metal for the kitchen exhaust duct.

e)Be sure to plan at least one exhaust register on the highest lived-in level of the house if it has 2 floors or more.

4.2 PLANNING OF THE DUCTWORK

Duct Recommended Maximum

Diameter Airflow Airflow

4” Ø 40 cfm 60 cfm
5” Ø 75 cfm 110 cfm
6” Ø 120 cfm 180 cfm
7” Ø 185 cfm 270 cfm
8” Ø 260 cfm 380 cfm

Use table beside to ensure that the ducts you
intend to install will be supporting airflows at
or under the recommended values. Avoid
installing ducts that will have to support
airflows near the maximum values and never
install a duct if its airflow exceeds the
maximum value.

4.3 CALCULATING DUCT SIZE

WARNING

CAUTION

When performing installation, servicing or cleaning the unit, it is recommended to wear safety glasses and gloves.

!

WARNING

!

When applicable local regulation comprises more restrictive installation and/or certification requirements, the
aforementioned requirements prevail on those of this document and the installer agrees to conform to these at
his own expenses.

4.3 CALCULATING DUCT SIZE (CONT’D)

4.3.1 Example for calculation:
Problem: My installation requires two exhaust registers (one for the kitchen, one for the

bathroom). I will connect these registers to a main duct connected to the unit (high speed
performance value of 140 cfm). What size of duct should I use for the main exhaust duct
and for the two end branches leading to the registers? (See Figure 9.)

Solution: Simplified method.

(For a more detailed method of calculating duct size refer to

ASHRAE HANDBOOK.)
Main duct:

Table indicates for a 6ӯ duct: Recommended Airflow: 120 cfm; Maximum
Airflow: 180 cfm. The high speed airflow of 140 cfm is close enough to the recommended
value (120) and far enough away from the maximum value (180). Therefore a 6ӯ duct
or larger is an appropriate choice for the main exhaust duct.

End branches: Each end branch will have to transport an airflow of 70 cfm (140 divided
by 2). The table indicates for a 5ӯ duct: Recommended Airflow: 75 cfm; Maximum
Airflow: 110 cfm.The high speed airflow of 70 cfm is close enough to the recommended
value (75) and far enough away from the maximum value (110). Therefore a 5ӯ duct or
larger is an appropriate choice for the 2 end branches.
NOTE: A 4ӯ duct would have been too small because the maximum acceptable value
for a 4ӯ duct is 60 cfm.

4.4.1 Fully Ducted System (as illustrated in section 3.1)
Stale air exhaust ductwork:

• Install registers in areas where contaminants are produced: kitchen, bathrooms, laundry rooms, etc.

• Install registers at 6 to 12 inches (152 to 305 mm) from the ceiling on an interior wall OR install them in the ceiling.

• Install the kitchen register at least 6 feet (1.8 m) from the oven.

• If possible, measure the velocity of the air flowing through the registers. If the velocity is higher than 400 ft/min then the register

type is too small. Replace it with a larger one.

4.4 INSTALLING DUCTWORK AND REGISTERS

WARNING

!

Never install a stale air exhaust register in a room where a combustion device is, such as a gas furnace or a gas
water heater or a fireplace.

CAUTION

The ductwork is intended to be installed in compliance with all local and national codes that are applicable.

4.4.2 Exhaust Ducted System (Source Point Ventilation) (see illustration, section 3.2)

Stale air exhaust ductwork: (same as for Fully Ducted System, section 4.4.1)
Fresh air distribution:

There are two methods for connecting the unit to the furnace:

Method 1: supply side connection

• Cut an opening into the furnace supply duct at least 18” (0.5 m) from the

furnace.

• Connect this opening to the fresh air distribution port of the HRV (use

metal duct

, see Figure 11).

• Make sure that the HRV duct forms an elbow inside the furnace ductwork.

• If desired, interlock (synchronize) the furnace blower operation with the

HRV operation. (See Section 6.)

WARNING

!

When performing duct connection to the furnace, installation must be done in accordance with all applicable
codes and standards. Please refer to your local building code.

Method 2: return side connection

• Cut an opening into the furnace return duct not less than 10 feet (3.1 m) from

the furnace (A+B+C).

• Connect this opening to the fresh air distribution port of the HRV (see Figure 12).

NOTE: For Method 2, it is not essential that the furnace blower runs when the unit is

in operation, but we recommend it. If desired, interlock (synchronize) the
furnace blower operation with the HRV operation. (See Section 6.)

CAUTION

When performing connection to the furnace supply duct, this duct must be sized to support the additional airflow
produced by the HRV. Also, use a metal duct. It is recommended that the HRV is running when the furnace is in
operation to prevent backdrafting inside the HRV.

4.7 CONNECTING THE DRAIN

Make a water trap loop in the tube to
prevent the unit from drawing
unpleasant odors from the drain
source. Make sure this loop is situated
BELOW the “T” as shown. This will
prevent water from being drawn back
up into the unit in case of negative
pressure. Run the tubing to the floor
drain or to an alternative drain pipe or
pail. Be sure there is a slight slope for
the run-off.

T

O DRAIN

Cut 2 sections of plastic tubing, about
12” (305 mm) long and attach them to
each drain fitting. Join these 2 short
sections to the“T” junction and main
tube as shown.

Attach the 2 plastic drain fittings to the
unit using the gaskets, washers and
nuts as shown.

) function consists in 2 modes: the standard mode and the special mode. Depending

on the unit models, the electronic board terminal of the units has additional jumpers (see below for configuration).

WARNING

Never connect a 120 volts AC circuit to the terminals of the Furnace Interlock. Use only the low voltage class 2
circuit of the furnace blower control.

!

For a furnace connected to cooling system:
On some older thermostat, energizing the ‘’R’’ and ‘’G’’ terminals at the furnace has the effect of energizing ‘’Y’’ terminal 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’’.
The ‘’Standard Furnace Interlock’’ cannot be used and an additional control relay will have to be installed.

• A magnehelic gauge capable of measuring 0 to 0.25 inches water gauge (0 to 62.5 Pa) and 2 plastic
tubes.

• Two flow collars (the size will vary depending on duct diameter).

What you Need to Balance the Unit

Preliminary Stages for Balancing the Unit

Insert the flow collars in the duct at each location (A and B on figure above). Make sure their arrows are pointing in the direction of the
airflow. Tape collars in place temporarily.

flow collar

Seal all the unit ductwork with tape. Close all windows and doors. Turn off all exhaust devices such as: range hoods, dryers and bathroom
fans. Make sure balancing dampers are fully opened

(F and G in figure below).

Choose appropriate locations for the 2 flow collars according to figure below :

• On the exhaust air duct (first measuring location, A)

• On the fresh air distribution duct (second measuring location, B)

• At least 36”(914 mm) away from the unit; at least 12”(304 mm) before or after a 90°elbow; at least 12”(304 mm) away from a
register.

NOTE: To get the best ventilation performance from Venmar 2.6 HE and vänEE 3000 HE, refer to Point 4.5.2 on page 11.

17

Balancing procedure

1. Set the unit to high speed.
Make sure that the furnace blower is ON if the installation is in any way connected to the ductwork of the cold air return. If not leave
furnace blower OFF.
If the outside temperature is below 0°C / 32°F, make sure the unit is not running in defrost while balancing. (By waiting 10 minutes
after plugging the unit in, you are assured that the unit is not in a defrost cycle.)

2. Place the magnehelic gauge on a level surface and adjust it to zero.

3. Connect tubing from gauge to flow collar in exhaust air stream (location A in figure above).
Be sure to connect the tubes to their appropriate

high / low

fitting. If the gauge reading drops to

below zero, reverse the tubing connections.

NOTE:It is better to start with the exhaust air flow reading because the exhaust typically has more

restriction than the fresh air, especially in cases of fully ducted and exhaust ducted installations.

Hold or place the magnehelic gauge upright and level. Record the reading.

9.

VP0005

VP0003

HIGH

FLOW

4. Move tubing to the other side of the unit (location B in figure on page 17) and note reading.
Adjust the fresh air balancing damper F until the reading at B is approximately the same as the
reading at A.

If the reading at B is less than the reading at A then go back and adjust the exhaust balancing
damper G to equal the fresh air flow.

5. Remove flow collars and reconnect the duct, then, seal with duct tape. Write the required airflow information on a label and stick it
near the unit for future reference: (date, maximum speed airflows, your name and phone number and business address).

NOTES:

• Most flow collar kits provide a conversion chart situated on the collar which enables you to convert magnehelic gauge readings to
equivalent cfm values.

• A difference of ± 10 cfm (± 0.015 inches water gauge) between the 2 readings is considered balanced.

• If you are using only one flow collar, then, after completing the first reading, transfer this measuring device to the other side of the
unit and take the second reading.

1) Motor: The motor is factory lubricated for life. Lubricating the bearings is not recom men ded.

2) The heat recovery core must be handled with care. We recommend that it be washed once a year, following the season of most
intense use, in order to insure maximum efficiency of the plastic partitions.
Allow the heat recovery core to soak for 3 hours in a solution of warm water and mild soap

. Rinse under a heavy stream of water.

3) The air filters are washable. Under normal con di tions, we recommend that they be washed every 3 months.
Use a vacuum cleaner to remove the hea viest portion of accumulated dust.
Then wash in lukewarm water.

4) Regularly check the screen on the exterior in ta ke hood and clean when necessary. Also check during very cold weather because
ice may grow on the screen located at the exterior intake hood.

10.1 Regular Maintenance

Annual service should include:

1) Cleaning filters, heat recovery core and the exterior air intake/exhaust hood.

2) Cleaning the wheels and the blower blades.

3) Cleaning the condensation tray with soapy water (make certain that the drain is not clogged).

4) Running the system and checking the diffe rent operating modes.

5) Measuring and calibrating rates of flow using the procedure descriptions in Section 9.

10.2 Prolonged Maintenance

WARNING

Risk of electric shock. Before performing any maintenance or servicing, always disconnect the unit from its power
source.

!

CAUTION

Hot water and a strong detergent will damage the heat recovery core.

CAUTION

Even a partial blocking of this air vent could cause the unit to malfunction.

CAUTION

Because the unit is suspended, two people are recommended to remove or install the heat recovery core. Do not
hold the heat recovery core using its plastic extrusions as handles.
