6.“When cutting or drilling into wall or ceiling, Do Not damage electrical wiring or other hidden utilities.

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 open- ing must be provided to allow replacement of exhaust air. One square foot of free open air inlet per 300 CFM of fan capacity is rec- ommended. The best location for air intake is at the opposite end of the attic. See: MINIMUM ATTIC INTAKE AREA 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 90º 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.)

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

UNRESTRICTED	WOOD LOUVER	METAL LOUVER

5.1 Sq. Ft.	6.4 Sq. Ft.	5.9 Sq. Ft.

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.)
