Typical Installations - Broan LinkLogic SMD6 Manual De Instrucciones

PLAN THE INSTALLATION
Planning the installation first requires selecting the most appropriate
installation approach. The chart below offers suggestions for the most
effective installation approach by considering a few important factors.
Further details on the two main types of installations are provided below.
• House has central duct work?
Yes
• Return-air side of duct work is
accessible -either the return-air trunk
or return - air plenum?
Yes
Damper connected to
return side of central
duct system
OUTSIDE AIR INTAKE LOCATION Proper design and location of the outside air intake location is critical in
ensuring that the Damper can safely and reliably provide an opening for
fresh air to enter the home. The following requirements for the location
of the outside air intake must be met:
•
appliance vents, chimneys, plumbing stacks, and bathroom or
kitchen exhaust vents. If local codes have more stringent separation
requirements, they shall apply.

TYPICAL INSTALLATIONS

Installations will vary according to the location in the home where the unit is installed and which model Damper is used. Use the following
illustrations and notes as guidance for your own installation. Always comply with local code requirements and in any instance where a detail
shown below conflicts with local code, the local code provision shall apply.

•
blockage from snow or other debris such as leaves, and at a
minimum of 1' above grade.
•
attics, adjacent dwelling units, or any enclosed part of the building.
The Damper should be installed to draw air directly from outdoors.
OUTSIDE AIR INTAKE OPENING PROTECTION
Because the Damper, together with the end cap and outside air
duct which are installed with it, will allow outdoor air into the indoor
environment, it is important to meet the following requirements:
•
protective bird screens to keep out animals and outside debris.
Clean screens often and do not remove.
•
must cover the entire opening of the outside air duct. This screen
•
for the protection of openings in exterior walls, including steps to
prevent moisture intrusion around the opening.
Note that the screen over the outside air opening is not a filter. It is
intended to prevent the intake of leaves, animals, or debris into the
outside air duct. A downstream filter is necessary to remove pollen,
dust, and other airborne particles. Potential filter locations are shown
below in the Typical Installations section.
MINIMUM RETURN AIR TEMPERATURE REQUIREMENTS
HVAC equipment manufacturers may have minimum requirements for
the air temperature in the return air plenum. Introducing outdoor air to
the return side of the central duct system may impact this temperature.
The installer should adjust both the size of the outside air duct and the
location of its connection to the return side of the central duct system in
a manner so that minimum air temperature requirements are satisfied
under design conditions.
