hood venting.
6.0 Installation
Step 1: Install (3) rubber grommets into Mounting Bracket (P/N
25007-1, included) to provide vibration isolation. Attach the fan to
the mounting bracket with (3) #10 self-tapping screws, provided.
Avoid over tightening screws.
Step 2: Select location for fan mounting. A location 2/3 along the
ducting, a minimum of 10 feet away from the inlet vent to the fan
or the Y/T of a multi-intake system will provide the quietest
operation. Fan should be mounted vertically to prevent moisture
from accumulating in the fan housing. Attach bracket to mounting
structure with the 1 1/4” screws provided.
Step 3: Connect ductwork between fan inlet and area to be vented
through inlet grille. Flexible, nonmetallic ducting is recommended
for quietest operation and easiest installation. Insulated flexible
ducting is highly recommended for bathroom ventilation in all
cold climate installations.
Step 4: Connect inlet grille(s). An optional backdraft damper may
be installed in the inlet grille to prevent cold air from backing into
the inlet and also prevent condensation from forming inside the
ductwork. Backdraft dampers are highly recommended at each
intake grille for bathroom ventilation in all cold climate
installations.
Step 5: Connect outlet of fan to outside vent. The outside vent may
go through the roof, sidewall or soffit as desired. Flexible,
nonmetallic ducting is recommended for quietest operation and
easiest installation. Insulated flexible ducting is highly
recommended for bathroom ventilation in all cold climate
installations.
Step 6: Make electrical connection to fan. Observe the proper
wiring connections (see Section 4.0):
