Planning the Duct Work
WARNING
o 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 wails or ceilings or into attics, crawl spaces or garages.
o Tape aii duct joints securely to prevent combustion by-prodJcts, smoke or odors from entering the home. Doing so
will also improve system efficiency.
- TO REDUCE THE RiSK OF FIRE, USE ONLY METAL DUCT WORK.
- DO NOT install more than one blower to increase the length of the duct run. Even small differences between blower
air flow rates can greatly reduce the air draw by the raised vent.
You must install one of the Dacor remote or indine blower
models listed below for the raised vent to operate properly.
See the blower installation instructions for directions. Only_.
one blower shall be installed.

When connecting the duct work to the back of the unit,
the customer must supply a 3 %" 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 1 5/8"X 16" exhaust out-
let on the unit and a 3 %" X 10" rectangular duct con-
nection. On bottom exhaust installations cut a hole in
the floor to allow the transition and/or duct work to pass
through the floor (see page 8).

, AHduct work materials (including screws and duct tape)
must be purchased separately by the customer.
, When pmanningnew duct work, always look for the
shortest, most direct route to the outside. See page
5 for examples.
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 atl connections with sheet metal screws and
tape all joints with certified sliver tape or duct tape.
, Use sheet metal screws as required to support the duct
weight.
, To prevent back-drafts, a damper at the duct outlet may
also be required.
