Venturi Assembly:
• Lay out the (4) venturi sections flat on the floor with the curve side of the sections facing up.
• Assemble the motor mount brackets (flat side down) in-between each venturi section.
Site Requirements:
• Rough Opening - 65¼” W x 65¼”H Square
• Side-By-Side Recommended OC Dimension - Minimum 75”
• Precautions should be taken in locations that receive winter precipitation accumula-
tion to prevent damage to fans from roof avalanches.
Damage to fans from ice, snow, or any other falling debris is not covered by warranty.
Common industry standard solutions are
> Extending roof eve beyond fan cone*
> Create a shelter a minimum of 6” above cone that extends beyond the fan cone*
> Install snow guards according to manufacturers recommendations
* The depth of J&D’s Magnum fan is 57”

Nuts from Bag 2 (Part 2), assemble the motor mount brackets and venturi sections.
— Tighten only the bolts and nuts securing venturi sections.
— Holding the motor brackets up so the back side is flush to the outside of the venturi
sections, tighten the bolts and nuts securing motor mounts and venturi sections.

Eye Bolt Installation:
• Stand the housing assembly up.
• Locate the dimple marks on the exterior of the venturi next to the motor brackets.
• With a 13/64” drill bit, drill the (2) holes for the eyebolts.
3

IS295-23G J&D Manufacturing • 6200 Hwy 12 • Eau Claire, WI 54701 • 1-800-998-2398 • www.jdmfg.com Page 6/24
Housing Side Panel Assembly:
• Start on a corner. With the front and back venturi section channels inserted into the grooves
of the housing side panel, slide the housing panel across the top until it hits the center seam
of the assembled venturi sections.
• Lift up on the center of the housing side panel and continue to slide housing side panel until it
is centered.
• Repeat until all four sides have housing side panels installed.
5
• Assemble (2) SS Eyebolts and (2) SS Serrated Flange Nuts #10-24 from Bag 9
(Misc. Hardware).
— With the flange facing up, thread (1) Serrated Flange Nut onto each Eyebolt
as far as it will go, as shown below.
• Insert each eyebolt nut assemblies up through the holes drilled in Step 3.
• Secure each eyebolt nut assembly with a SS Serrated Flange Nut #10-24 from Bag 9
(Misc. Hardware), flange facing down.
• Using 3/8” wrench tighten each eyebolt assembly.
NOTES:
- Turn the eyebolts so the opening of the loops are facing each other.
- Where the eyebolts are installed is now considered the TOP of the fan.

Installing Housing Corner Caps:
• Place a housing corner cap onto the housing between (2) housing side panels assembled in the
previous step.
• Using the included #3 Phillips Bit from Bag 1 (Tools) and (6) #14-10 x 2” Screws from
Bag 2 (Part 3), screw the corner to the panels.
NOTE: The screws should draw the housing side panel up tight to the housing corner cap, but
the housing side panel may need to be pushed/pulled as it is being screwed together.
• Repeat until all four housing corner caps have been installed.
6
Motor Installation:
NOTE: 2 person lift is recommended for handling of 105lb motor.
• Using the pallet the fan came on, place the motor in the center between the pallet slats with
the shaft facing up.
• Place housing, curved side down, over motor with the housings eyebolts aligning with motor
wiring ports as shown below.
• Use scrap wood 2x4’s or other items to lay between the pallet and the fan housing to align
motor brackets with motor and to support the housing.

• Assemble the (8) 3/8”-16 x 3/4“ Bolts and (8) 3/8” Washers from Bag 3 (Motor).
• Starting each bolt and washer assembly by hand, begin attaching motor to brackets - since
motor has an aluminum housing care must be taken to not cross-thread or strip-out the
motor mounting threads.
• Once all motor mounting hardware has been hand started, torque the bolts to 23 ft-lbs using
hand tools only.
8
Prop Installation:
• Insert the 1/4” x 2” Machine Key from Bag 9 (Misc. Hardware) into the key notch on the
motor shaft.
• Slide prop onto the keyed motor shaft until 1/4” of the motor shaft is protruding.
• Secure prop by tightening the (2) set screws (located on underside of prop) to 10 ft-lbs.
• Rotate the blade to make sure there is no interference.

Rubber Gasket Installation:
• Peel 1’ of the backing paper off the rubber gasket, start applying the rubber gasket at the
bottom (opposite from the eye hooks installed in Step 4) with the raised portion of the gasket
to the center and flush to the interior of the venturi, as shown below in the cutaway view.
• Continue peeling off the backing paper 1’ at a time and stick the gasket around the circumfer-
ence until you come to where you started. Trim end of gasket to allow for a ¼” gap between
the ends of the gasket to allow condensation to drain.
• Go back and press down on the flat part of the gasket all the way around the housing to
make sure it is fully adhered to the venturi.

Damper Door Striker Plates Installation:
• On the edge of the housing venturi under the just placed rubber gasket locate the 4 striker
plate grooves nearest the center of the fan venturi,(do not use the ones nearest the top or
the bottom of the fan).
• Carefully lift off the rubber gasket over the striker plate groove and insert (1) SS Damper
Door Striker Plates from Bag 9 (Misc. Hardware) at each location, angle the striker plate
so the angle matches the fan housing. To secure the striker plates, press the rubber gasket
back down.
NOTE: No hardware is used to secure striker plates at this time.

Doors), use 1/16” Hex Wrench from Bag 1 (Tools) to tighten.
• Repeat last two steps until all (4) Damper Door Magnets are installed.
13
Identifying the Sides of the Damper Doors:
• Back side of damper doors
- Have flat raised circular feet for attaching magnets.
