8. Position the combination control
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 combination control is a delicate
instrument, use screws instead of
nails when fastening bracket to roof
rafter.

connections inside the combination
control 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 in the combination
control. 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 green screw in the bottom
of the combination control box.
9. WARNING! Turn o 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 combination
control box and bring to power
distribution panel. Feed through
bushing and connect to 15-amp
circuit breaker.

Steps
to attic ventilation
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 pull air in from lower exhaust vents rather than
from the intake vents. Intake air must come from intake vents located
near the lower part of the attic space to properly ventilate the total attic
area and eliminate weather infiltration.
Install ONLY ONE TYPE of Exhaust Ventilation within a
common attic area.
Exhaust Vents pull air from the easiest intake source. Vent types cannot
be mixed. The use of different types of exhaust vents could make one of
the vents act as intake for the other. Intake air must come from intake
vents located near the lower part of the attic space to properly ventilate
the total attic area and eliminate weather infiltration.
Install a BALANCED SYSTEM of Intake and Exhaust
Ventilation.
50% Intake Ventilation - Intake vents located near the lower part of
the attic area are required to balance out your ventilation system.
50% Exhaust Ventilation - Use a Lomanco Ventilation Selector Guide,
the calculators at lomanco.com, or the Lomanco Vent Selector App to
determine the number of vents needed to properly ventilate an attic to
meet the minimum code ventilation standard.
