Recovery Needs According To Geographical Location; Planning The Installation - NuTone GSEH3K Installation Instructions Manual

3. RECOVERY NEEDS ACCORDING TO GEOGRAPHICAL LOCATION

When recovery is important, it can be hard to find the appropriate unit. Use the map below to determine which between heat
recovery (GSHH3K model) or energy recovery (GSEH3K model) will satisfy the specific needs of the consumers.
OLYMPIA
SALEM
SACRAMENTO
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.

4. PLANNING THE INSTALLATION

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.
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.)
The Central Draw Point
installation can be performed.
Example: Basement installation
in Section 5.4.1
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.
