1. Cut a hole in the ceiling under where the HV1450 will be installed. Suggested methods for making
the proper sized hole in the ceiling are; cut a pilot hole under where the fan will be installed. Cut toward
the edge to find the joist pattern and layout the fan opening on the ceiling; OR the four corners of the
opening from the attic side and draw a line between each of the four corners to layout the fan opening;
OR use a stud finder to locate the joists, cut a template from the fan packaging material and use the
template to layout the fan opening.The dimensions of the hole should be
no greater than 22-1/2” x14-1/2”. This will allow for the grille to cover the
exposed sheetrock edges.
2. The fan housing will fit either 16” or 24” on-center framing. Cut two
pieces of 2x stock (2x6 or 2x8 etc.) of the same dimension as the exist-
ing joists. Add these pieces of framing to form a box between the joists.
3. Install foam weatherstrip material (not supplied) on the top of the joists
and added framing. Caulk the joist between the ceiling and the 2x stock.
Some types of ceilings are spaced away from the joists. Any gap between
the 2x’s and the ceiling should be sealed prior to final installation. Use a
low expansion spray foam sealant (not supplied).
4. Insert the threaded end of the hex standoffs through the hole in the
housing. From the backside of the housing secure each standoff with a
locknut. Place the damper on the housing with the label side facing the
attic space. Pass the standoffs through the holes in the damper. Secure
the damper in place with a flat washer and phillips head screw. The
damper should move freely about the standoffs.
5. Set the HV1450 on the gasket with the damper facing into the attic. The
housing will fit the framing with the mounting flanges over lapping the joists.
6. If desired, secure the HV1450 to the top of the joists using wood screws
(not provided). When fastening the mounting flange to the joists, care
should be taken that all screws are tightened evenly.
7. Wire the HV1450 as shown in the wiring diagram. It is recommended
wiring of the HV1450 be done by licensed electrician.
8. Install grille (6 screws included) on the ceiling below the fan.
Installation
Tools and supplies needed (Not Included):
You will need the following items: two pieces of 2x stock to match your existing framing,
a saw to cut the hole in the ceiling, a hammer or screw gun to attach the blocking to the existing joists, a Phillips head screw driver to attach the
grille, weather strip material and low expansion spray foam sealant.
TROUBLE SHOOTING:
The most common problem with the HV1450 is
caused by incorrect wiring. Before you check anything else make sure
WHITE wire in HV1450 is connected to 115 VAC line neutral: BLACK wire
is connected to a switch that will make it hot when the switch is closed.
CARE:
All the motors are permanently sealed and do not require oiling. To
keep dirt, dust and debris from fan, we recommend you periodically remove
the grille from within the living space and dust the fan blades. Please remem-
ber to make sure that the fan is OFF before dusting the fan blades
