Description
The Marley Engineered Products gable mounted attic ventilator is
fully automatic and designed for general ventilating use only in the
attic spaces of houses, apartments and other small buildings. Unit
can be installed behind existing attic louvers to exhaust hot air or
pull in cool air. An accessory dehumidistat can be used with this
unit to automatically activate in the winter to help eliminate excessive moisture.
The ventilator comes complete with mounting brackets, 18”
armored flexible cable, prewired automatic thermostat mounted in
junction box, thermally protected motor, and heavy gauge plated
steel housing.
Unpacking
Unpack carefully. Inspect for loose, missing or damaged parts. In
the event of missing components or hidden damage, immediately
contact your distributor or the delivering carrier concerning discrepancies. The motor/fan assembly has been carefully factorybalanced. Care should be taken when handling to avoid damage
resulting in unnecessary vibration and noise.

1. Do not use this fan with any Solid-State Speed Control Device.
2. Use this unit only in the manner intended by the manufacturer. If you
have questions, contact the manufacturer.
3. Before servicing or cleaning unit, switch power off at service panel and
lock service panel to prevent power from being switched on accidentally.
4. Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards, including
fire-rated construction.
5. 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 and Air
Conditioning Engineers (ASHRAE), and the local code authorities.

7. CAUTION: This unit has an unguarded impeller. Do not use in
locations readily accessible to people or animals.
8. CAUTION: For general ventilation use only! Do not use to exhaust
hazardous or explosive materials and vapors.
INSTALLATION
NOTE: For maximum operating efficiency, proper intake air opening must be provided to allow replacement of exhaust air. One
square foot of free open air inlet per 300 CFM of fan capacity is recommended. The best location for air intake is at the opposite end
of the attic. See:
MINIMUM A TTICINTAKEAREA REQUIRED
section.
1. This gable ventilator is designed to mount behind existing
louvers in an attic. If a louver is not present and one must be
installed, it should be mounted in the center of the uppermost
portion of the gable. The area of the louver should be greater
than outlet area of ventilator. (See Figures 4 and 5.)
2. There are four sets of holes spaced 90
º apart in housing,
providing a choice of four depth positions. Reversing brackets
produces eight positions. Select proper mounting holes to
align bracket and mounting structure on louvers. (See Fig. 3.)

— Mounting Housing to Brackets
3. Ventilator may be mounted directly against a gable louver as
shown in Figure 4. If louver is sufficiently strong, mounting
brackets may be nailed or screwed onto it.
Figure 4
— Mounting to Gable Louvers
4. If mounting the vent directly to gable louver is undesirable, a
pair of furring strips may be suspended vertically at a minimum
of 16 3/4” apart.
5. Ventilator may also be mounted on rectangular louvers as
shown in Figure 5.
6. For better performance, cover any open louvered area around
vent with plywood or other suitable material. This will improve
efficiency of air exchange between attic and outside air. It will
also prevent thermostat from being directly affected by outside
air.

MINIMUM ATTIC
INTAKE
AIR REQUIRED
Sufficient intake area must be provided in the attic to ensure that
fan will not be overloaded and that it will deliver its rated CFM. This
can be accomplished with some type of attic venting such as gable
louvers or undereave vents. The table below shows minimum
intake area needed for each fan installed.
MINIMUM ATTIC INTAKE OPENING REQUIRED
Note: If openings are covered with 1/2” hardware cloth or large
mesh expanded metal, increase area by 20%. Double area if fly
screen is used.
WIRING
WARNING: TO REDUCE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT USE THIS FAN WITH ANY SOLID STATE
SPEED CONTROL DEVICE.
Note: This fan is designed to run on 120V, 60 HZ power only.
1. Thermostat box can be screwed or nailed to a rafter by
mounting bracket provided. If nailed, remove thermostat from
box before nailing to avoid damage. Connection to existing
circuit must conform to local electrical code regulations.
2. Wiring of this unit is done inside attic. Remove cover from
thermostat/junction box. Bring power cable at least 6 inches
into the box. Fasten power cable to box with appropriate
connector.
3. For standard installation, connect the two leads in thermostat/
junction box to the two supply leads. Attach ground wire from
the supply to the green ground screw in the box. (See Fig. 6.)
