ed) wiring must be used. DO NOT USE
AN EXTENSION CORD.
• To avoid risk of fire, electrical shock
and other injuries, switch power off
at service panel and tag prior to the
installation.
• Do not operate fan in areas where gas
or oil-fired equipment is in operation.
• Wear safety goggles when drilling,
hammering, or cutting materials.
OPERATING YOUR FAN
IMPORTANT Do not operate your fan
without first providing adequate ven-
tilation (such as a door or window) to
provide the proper inlet airflow.
WARNING BEFORE PROCEEDING
WITH THE INSTALLATION, SWITCH
POWER OFF AT SERVICE PANEL. The
fan requires a 120-volt AC power source
with at least 5-amp capacity (10-amp for
24" and 30" GPX). All electrical work
must be done in accordance with local
building codes, using approved mate-
rial. Follow the wiring diagram shown
on next page.
ITEMS REQUIRED FOR INSTALLATION
• Screwdriver
• Straight edge
• Safety goggles • Pencil
• Measuring tape
• Electric drill
• Power saw or hand saw
• (12) wood screws 1/4" x 3/4" lg.
GPX FANS ARE EASY TO INSTALL:
1. Simply cut a square opening in the
wall. (See chart below).
2. Slide the fan into the opening from
outside the structure. Using (12) 1/4"
x 3/4" screws, attach flange to your
structure.
3. Connect the motor to a 120-volt,
60-Hz single-phase power source.
Proper installation is required to
achieve maximum efficiency. It is nec-
essary to provide adequate ventilation
to meet minimum intake air require-
ments. This prevents pressure buildup,
which will reduce the fan's efficiency.
Inadequate intake air can also lead to
premature motor failure.
CAUTION - SAFETY RULES
WARNING: TO REDUCE THE RISK OF
FIRE, ELECTRIC SHOCK OR INJURY,
OBSERVE THE FOLLOWING:
• Use this unit only in the manner
intended by the manufacturer. If you
have questions, please contact manu-
facturer.
• Before servicing or cleaning unit,
switch power off at service panel and
tag service panel to prevent power
from being switched on accidentally.
• Installation and electrical wiring must
be done by qualified person(s) in
accordance with all applicable codes
and standards, including fire-rated
construction.
• Sufficient air is needed for proper
combustion and exhausting of gasses
through the flue (chimney) of fuel-
burning equipment to prevent back-
drafting. Follow the heating equipment
manufacturer's guidelines, along with
safety standards such as those pub-
lished by the National Fire Protection
Agency (NFPA), the American Society
for Heating, Refrigeration & Air
Conditioning Engineers (ASHRAE),
and your local code authorities.
• CAUTION Check for hidden electrical
wiring or utility lines before cutting or
drilling into a wall or ceiling.
• CAUTION
For general ventilating only.
DO NOT use to exhaust hazardous or
explosive materials.
• Your GPX fan will operate only on 120
volt AC, 60Hz (cycle) current.
• A permanent, THREE-WIRE (ground-
IMPORTANT: READ INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING
TO INSTALL, OPERATE OR SERVICE THIS FAN.
