When exchanging air with outside: ZONE A: GSHH3K unit recommended* ZONE B: GSEH3K unit recommended

* In ZONE A, the GSEH3K unit may be used, but below 16F, the duration of exchanging air with outside will decrease.

VN0004A

The Broan Fresh Air Systems units are versatile appliances capable of delivering filtered air (model GSFH1K) or both filtered and fresh air to your home (models GSVH1K, GSHH3K and GSEH3K). Because each installation is different, it is recommended you take the time to plan your installation. The three main areas to plan for are:

• Where to locate the Broan Fresh Air Systems unit

• How to pick-up the air from the room and distribute the filtered or fresh/filtered air

• Where to bring fresh air from outside and exhaust stale air to outside (models GSVH1K, GSHH3K and GSEH3K).

Use the following chart to determine the appropriate installation method for the unit.

Example: Basement installation

in Section 5.4.1

Example: Crawl space installation

in Section 5.5.1

CAUTION

Do not install duct or duct connector directly above the furnace. Do not connect the plenum connection closer than 2’ (0.61m) to the furnace, as measured along the length of the duct.

The Return-to-Return

installation can be performed.

The Central Draw Point

installation can be performed.

Is the house equipped with a furnace or air handler?

4. PLANNING THE INSTALLATION

YES

Use Stand Alone installation.

See Section 5.3.

YES

Is there enough space to connect the unit duct(s) to the existing

furnace or air handler ductwork? (The unit duct connection can be

performed on the cold air return duct, at a minimum linear distance

of 2’ (0.61 m) from the furnace/air handler.)

Page 8

.1 PLANNING OF THE DUCTWORK

• Keep it simple. Plan for a minimum of bends and joints.

• Keep the length of insulated ducts to the outside of home to a minimum.(not for HEPA Filtration model GSFH1K).

• Do not ventilate crawl spaces or cold rooms.

• If the house has two floors or more, be sure to plan for at least one exhaust register on the highest lived-in level.

Use the table below to plan the flexible ducts length.

5. TYPICAL INSTALLATIONS

Installations may vary according to the model number, the product orientation (vertical or horizontal) and the location in the home where the unit is installed. Use the following illustrations as guidelines to help you decide the appropriate installation.

The unit allows for multi positional mounting (vertical or horizontal). It may be hung to the joists (preferred method), or it may be laid down on one of three surfaces, and installed either vertically or horizontally.

NOTE: For more details, see Points 5.3 and 5.4 in Section 5 INSTALL THE UNIT. In every case, bathroom fans and a range hood should be used as spot ventilation to exhaust stale air. Also, for homes with more than

one level, we recommend placing one exhaust register at the highest lived-in level. There are three installation methods: Stand Alone, Central Draw Point* and Return-to-Return*. * Different connections to a forced air system. Multiple furnaces or air handlers may require installation of Broan Fresh Air Systems on each system for maximum IAQ benefit.

NOTE: A grounded three-prong electrical outlet has to be available within 3 feet from the unit.

WARNING

Do not attempt to recover in any ways the exhaust air from a dryer or a range hood. This would cause clogging of the filters and recovery module (if applicable); this is also a fire hazard. Not following this warning will void the warranty.

8. BALANCING PROCEDURE (GSVH1K, GSHH3K AND GSEH3K UNITS ONLY)

8.1 WHAT YOU NEED TO BALANCE THE UNIT

• A magnehelic gauge capable of measuring 0 to 0.5 inches water gauge (0 to 125 Pa) and 2 plastic tubes.

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

VP0005

Flow collar

8.2 PRELIMINARY STAGES FOR BALANCING THE UNIT

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 open

(F and G in figure below).

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

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

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

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

• At least 12” (304 mm) away a from a balancing damper (F and G in figure below).

12¨(304mm)

36¨(914mm)

VP0014A

12¨(304mm)

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

8.3 INSTALLATION OF FLOW COLLAR

8.4 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.

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 illustration 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 stand alone and central draw point installations.

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

4. Move tubing to the other side of the unit (location B in illustration above 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: 1. Most flow collar kits provide a conversion chart situated on the collar which enables you to convert magnehelic gauge readings

to equivalent cfm values.

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

3. 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.
