Installation Specifications
ADT2 Transition
On side exhaust installations, allow five inches of space
•
on the side for the ADT2 exhaust transition plus addi-
tional space for the duct attached to it (X).
All duct work materials (including screws and duct tape)
•
must be purchased separately by the customer.
When planning new duct work, always look for the
•
shortest, most direct route to the outside.
You can increase the duct size over the duct run if
•
desired. To prevent a back draft, never decrease the
duct size over the run.
Do not rely on duct tape alone to seal duct joints.
•
Fasten all connections with sheet metal screws and
tape all joints with certified silver tape or duct tape.
Use sheet metal screws as require to support the duct
•
weight.
To prevent back-drafts, a damper at the duct outlet may
•
also be required.
Make sure duct work does not interfere with floor joists
•
or wall studs.
With concrete slab construction, “box-in” the duct work
•
to prevent it from collapsing when the wet concrete is
poured. Also allow room for electrical conduit from the
remote blower.
Cross-drafts or air currents caused by adjacent open
•
windows or doors, heating/air conditioning outlets, ceil-
ing fans and recessed ceiling lights reduce vent effi-
ciency.
Planning the Duct Work
WARNING
To reduce the risk of fire and to properly exhaust air,
•
be sure to duct air outside the house or building. Do
not vent exhaust air into spaces within walls or ceil-
ings or into attics, crawl spaces or garages.
Tape all duct joints securely to prevent combus-
•
tion by-products, smoke or odors from entering the
home. Doing so will also improve system efficiency.
Do not exhaust more than one vent into a single
•
duct run.
For proper operation this unit must be installed with
•
a remote blower. Use only Dacor models REMP3 or
REMP16.
Use only duct work constructed of materials deemed
•
acceptable by state, municipal and local codes
DO NOT
•
install an additional in-line or external blow-
er to increase the length of the duct run. Even small
differences between blower air flow rates can greatly
reduce the air draw by the hood.
The ERV raised vent can be configured to exhaust
•
through the back, the bottom or either side.
When connecting the duct work to the back of the unit,
•
the customer must supply a 3 ¼” X 10” rectangular
transition to make the connection.
For side and bottom exhaust connections, use the sup-
•
plied ATD2 transition to connect the duct work to the
unit. It transitions between the narrow exhaust outlet on
the unit and a 3 ¼” X 10” rectangular duct connection.
On bottom exhaust installations cut a hole in the floor
to allow the transition and/or duct work to pass through
the floor.
