Electrical Specifications
WARNING
The electrical service to the range hood should be
installed only by a licensed electrician.
It is the owner’s responsibility to ensure that the electrical
connection of this appliance is performed by a qualified
electrician. The electrical installation, including minimum
supply wire size and grounding, must be in accordance
with the National Electric code ANSI/NFPA* (or latest
revision) and local codes and ordinances.
* A copy of this standard may be obtained from:

Quincy, Massachusetts 02269-9101
Connect the hood to a junction box supplied by a 120
Vac, 60 Hz dedicated, grounded, 3-wire (hot, neutral,
ground) circuit protected by a 15 Amp. circuit breaker
or time delay fuse. It must be installed a minimum of 17
inches above the bottom of the hood.
Recirculating Configuration
Recirculating Kit # AVPH1 contains the parts necessary
to convert a PHW series hood to a recirculating configu-
ration in instances where exhausting the hood outside
the building is not practical or desired. The kit consists
of a top cap and 2 charcoal filters. When installed, the
top cap redirects air flow out the vents in the sides of the
hood chimney assembly. The provided charcoal filters are
installed underneath the mesh type filters included with
the hood. The charcoal filters reduce smoke and fumes
before the hood exhaust is vented into the room.

Ducted Installations - Planning
the Duct Work
WARNING
• To reduce the risk of fire and to properly exhaust air,
do not vent exhaust air into spaces within walls or
ceilings or into attics, crawl spaces or garages.
• To prevent combustion by-products smoke or odors
from entering the home and to improve efficiency,
tape all duct joints securely.
• Do not exhaust more than one vent into a single
duct run.
• TO REDUCE THE RISK OF FIRE, USE ONLY
METAL DUCT WORK.
•
DO NOT
install an additional in-line or external
blower to increase the length of the duct run. Even
small differences between blower air flow rates can
greatly reduce the air draw of the hood.
• Local building codes may require the use of makeup
air systems with ventilation systems that move air
greater than the specified movement rate (CFM). The
specified rate varies based on locale. Consult a quali-
fied HVAC specialist when designing the system for
the requirements in your area and to assure optimal
performance.
• All duct work materials (including screws and duct
tape) must be purchased separately by the customer.
• The hood exhaust connects to an 8-inch round duct.
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. If existing duct work is smaller
than 8 inches in diameter, remove it and replace it
with 8-inch duct work.
• Do not rely on 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.
• When planning new
duct work, always look
for the shortest, most
direct route to the out-
side. Venting can be
done through the roof
or directly through the
back wall to the out-
side as shown.
• Make sure duct work
does not interfere with
floor joists or wall
studs.
