fire-rated construction codes and standards.
4. Sufficient air is needed for proper combustion and exhausting of gases
through the flue (chimney) of fuel burning equipment to prevent back-
drafting. Follow the heating equipment manufacturer’s guideline and
safety standards such as those published by the National Fire Protection
Association (NFPA), and the American Society for Heating, Refrigeration
and Air Conditioning Engineers (ASHRAE), and the local code authorities.
5. When cutting or drilling into wall or ceiling, do not damage electrical
wiring and other hidden utilities.

. Hold housing in place so that
the housing tabs contact the bottom of the joist. The housing mounts with
four (4) screws or nails. Screw or nail housing to joist through lowest holes
in each mounting flange, then through highest holes. NOTE: Mounting to
I-JOIST (shown) requires use of SPACERS (included) between the highest
hole of each mounting flange and the I-joist.

CLEANING & MAINTENANCE
For quiet and efficient operation, long life, and attractive appearance - lower or
remove grille and vacuum interior of unit with the dusting brush attachment.
The motor is permanently lubricated and never needs oiling. If the motor
bearings are making excessive or unusual noises, replace the motor/blower
wheel assembly.
OPERATION
Use an on/off switch or speed control to operate this ventilator. See “Connect
Wiring” for details. Use of speed controls other than the Broan Models 78V
and 78W may cause a motor humming noise.
The ducting from this fan to the outside of the building has a strong effect
on the air flow, noise and energy use of the fan. Use the shortest, straightest
duct routing possible for best performance, and avoid installing the fan with
smaller ducts than recommended. Insulation around the ducts can reduce
energy loss and inhibit mold growth. Fans installed with existing ducts may
not achieve their rated airflow.
Use a roof cap or wall cap that has a built-in damper to reduce backdrafts.
Plan to supply the unit with proper line voltage and appropriate power cable.
