«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 ceilings or into attics, crawl_ spaces or garages.
*-Tape-all duct joints securely.to prevent combustion by-products, smoke or odors from entering the home. Doing so
«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 in-line blower
models listed below for the raised vent to operate properly.
See the blower installation instructions for directions. Only
one blower shall be installed.

The ERV raised vent can be configured to exhaust through
the back, the bottom or either side by removing the
appropriate exhaust knock out shown below.

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
outlet on the unit and a 3 %” 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 (see page 8).

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. 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 all connections with sheet metal screws and
tape all joints with certified silver 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.
