Power Vent Installation Instructions
INSTALLATION
1. Determine approximately where on your
roof you will place your Power Ventilator.
•At the highest point in your attic or
air space. Best if centered on roof
length, and less conspicuous if
placed on side away from street.
•IMPORTANT: Keep the highest
part of the dome lower than
the ridge line to ensure that the
dome's edge is NOT above ridge
line. (Typically, the center of the
vent should be about 24 inches
down from the ridge.)
•Establish your position with
accuracy (because you will want
to duplicate it inside your attic) by
measuring down from the ridge
and over from the roof edge.
2. Working now from the inside, mark your
planned opening (as you established
position when on roof) and relocate
your position to be centered between
two rafters. Drive a nail into the roof so
that it can be easily found when you
return to the roof. Before you return
to the roof, be sure that you have:
(a) string or compass, (b) drill and drill
bit, (c) keyhole or electric jig (saber)
saw with a sharp coarse blade, (d)
ventilator and base, (e) roong nails
and hammer, and (f) roong cement
and applicator.
3. Using the nail driven from the inside
as center, scribe a 14” diameter circle
using string or compass. Care should
be taken not to make the hole too large.
4. Drill a starting hole for sawing inside
the scribed circle.
5. Starting in the drilled hole, cut circular
opening, following the scribed line. Use
either keyhole or an electric jig (saber)
saw with a sharp coarse blade to cut
shingles and roof boards at one time.
If you do not have a coarse blade, cut
away shingles inside the circle with
utility knife before cutting roof boards.
6. Carefullyremoveroongnailsfromtop
rowofshinglessothattheashingof
the ventilator will slide under top row.
Slide ventilator carefully into place with
arrow pointing up, letting thermostat
hang down into opening. Fasten the
aluminum base to roof boards with
roongnails.Keepheadsofnailsunder
shingles wherever possible.
7. Finish the exterior mounting by sealing
all seams and nails with roong
cement. Use cement also to fasten
down loose edges of shingles. Return
to the attic. You now have to mount
the thermostat and connect the wiring.

qualied person(s) in accordance with all applicable
codesandstandards,includingre-ratedconstruction.
D. Sufcient air is needed for proper combustion and
exhaustingofgasesthroughtheue(chimney)offuel-
burning equipment to prevent back drafting. Follow
the heating equipment manufacturer’s guide lines
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.
E. When cutting or drilling into wall or ceiling, do not

Sharp edges are exposed during installation. Use
gloves and other safety equipment to avoid accidents.
WARNING -Toreducetheriskofreorelectricshock,
do not use this fan with any solid state speed control.
IMPORTANT
With the power vent installed, at least 780 square
inches of inlet area must be provided. This is achieved
by installing 12, 8” x 16” intake vents, measuring 65
square inches each.
OPERATION
Your ventilator will operate automatically as needed.
The adjustable thermostat has been set at the factory
to come on at 100°F., off at 85°F. The motor has been

NOTE:If the dome is removed for
any reason, torque the mounting
screw to a maximum of 100 inch
pounds when reinstalled. CAUTION
-DONOTOVERTIGHTEN
8. Position thermostat base high (in
the warmest part of the air space)
and above the ventilator opening.
Makesurethatexiblecabledoes
not touch the roof or rafters. (This
will eliminate vibration noise.)
The thermostat is a delicate
instrument, use screws instead
of nails when fastening bracket to
roof rafter.
Your Lomanco Power Ventilator
MUST be wired as shown. Make all
connections inside the thermostat
box. Connect white (neutral) wire
from a power supply to white wire
on motor. Connect black (hot) wire
from power supply to black wire
on the thermostat and black wire
on switch. The other black wire
on the thermostat and black wire
on switch have been connected
to the black wire on the motor at
the factory but should be checked
to ensure a good tight connection.
The ground wire from the supply
should be connected to the ground
wire from the thermostat box.
9. WARNING! Turn off power
before connecting power wires to
ventilator. Your power feed wire
should be 14 gauge or larger wire
size (two wires plus ground). Take
from thermostat box and bring to
power distribution panel. Feed
through bushing and connect to
15-ampcircuitbreaker.
•Black to circuit breaker
•White to neutral base
•Plain to ground base
Recheck your connections
then turn the power on. You should
now enjoy the advantages of a
Power Ventilator, operating as the
thermostat demands.
A test switch has been provided. To
make sure your Lomanco Power
Ventilator is operating properly,
simply “PUSH TO TEST.” Caution
should be taken to ensure that no
body parts come in contact with
any of the vent’s moving parts
during this test.
NOTE: To control humidity in your
attic, a humidistat is also available.

DO install all Exhaust Ventilation at the SAME HEIGHT within a common attic area.
Installation of exhaust vents at more than one level on a roof allows the upper exhaust vent
to wrongly pull air in from lower exhaust vent rather than from the sot Intake Vents.
DON’T install exhaust vents at dierent heights.
DON’T install Ridge Vents down the hip.
DO install ONLY ONE TYPE of Exhaust Ventilation within a common attic area. Exhaust
Vents pull air from the easiest Intake source. e use of two or more types of exhaust
vents such as Power Vents with Roof Vents or Gable Vents with Ridge Vents or Roof
Vents could make one of these vents act as intake instead of pulling air from the sot
vents.
DON’T mix dierent types of exhaust vents.
DO install a BALANCED SYSTEM of Intake and Exhaust Ventilation. 50% Intake and 50%
Exhaust is a balanced system. Improper intake may lead to snow or rain inltration into
the exhaust vents.
