2.1 FRAMING

Step 1

Construct a framed opening in ceiling that is

⁄2”W. x 25

⁄2”L. and fasten to trusses or

bracing between trusses. Trim out framing with

‘J’-trim if a metal ceiling is used. See Figure 1A

and 1B. If inlet is being installed in a house

with a Tri-Ply ceiling, construct frame as shown

in Figure 1C.

Installation Instructions

Figure 1A

Figure 1B

Step 2A

The Spring Counterweight Assemblies

and other hardware will already be

assembled as shown in Figure 2. The

Lift Line should be turned towards

actuator and Eye Bolt will be away

from actuator.

Step 2B

The doors will be held closed with the

latch. Keep doors latched and remove

the (4) screws shown. While removing

these screws make sure the washer

comes off the inlet and stays with the

screw. These screws will be used in

Step 3.

See Figure 2.

Figure 1C

Figure 2

If installing inlets near heaters, it is

recommended to install the BI28/BI48 inlet

at a location far enough from heaters that

will give a maximum temperature of 150°F.

This should be approximately 2-3 ft. from

the heater.

Step 3

Turn Spring Counterweight Assembly over and set on frame of inlet and secure assembly with (2) of

the screws and washers removed in Step 2B. See Figure 3. Repeat for other Spring Assembly.

2.2 Inlet Mounting

Step 5

Apply bead of caulk around top of inlet as shown in Figure 5A. Position inlet into framed opening and

attach inlet using (8) Hex Head Screws [A] provided. See Figure 5B. Be careful not to over tighten as this

may pull the Inlet Frame out of shape.

Step 6

To ensure an airtight fit, caulk around outside of 2x4 Framing and Inlet Frame.

Installation InstructionsChapter 2

Step 7

Proceed to routing main actuator cable or rod through holes in Inlet Frame. It is required to utilize a spring

or weight on actuator cable end opposite actuator. Once the cable is routed and the actuator is in the open

position, begin connecting the Lift Lines from each inlet door to the actuator cable using Cable Clamp [B]

provided. See Figure 6A and 6B.

Latch Operation

Step 8

Latch is pre-installed near center of door. Rotate latch upward to unlock and downward to lock.

When inlet is in normal operation, be sure latch is in up position so it does not interfere with door

closing. See Figure 7A and 7B.

Cabling

Step 9

Attach pulleys in line with the main rod or cable running through each BI28/BI48. See Figure 8A and 8B.

CablingChapter 4

Step 10

On each end of the run of BI28/BI48 inlets run a cable

through pulleys to winch or actuator on one end and to

weights or return spring on other end.

See Figure 8A, 8B and 9.

Figure 9

Step 11

With the winch or actuator at its fully closed position, check and

readjust each BI28 door tightly closed. Use winch or actuator to

open and close inlets a few times to make sure the doors open and

close smoothly

QM1112r3

Operation

Note:

To achieve a lower static pressure

move the spring toward hinges (inward)

and to achieve a higher static pressure

move spring towards outside of the inlet

(outward). See Figure 10.

Step 1

Start by setting each spring as light

as possible, that still allows the doors

to close when the fans are off. Note:

installation on a sloped ceiling will

typically require a heavier setting on the

high (uphill) side and a lighter setting on

the low (down hill) side.

Step 2

With inlets winched fully closed, turn

on your minimum ventilation fans.

Then adjust (release) the mechanical

hardware (actuator or winch) gradually

until you achieve the desired static

pressure. The winching limits the inlet

door opening so that all the doors open

evenly and the desired static pressure is

achieved when the minimum ventilation

fans run..

Step 3

Once the winching is set, turn fans off

and recheck to ensure all the inlets are

closing fully.

Figure 10

Note:

Spring Position settings

may vary from inlet to

inlet. Adjust each inlet

as needed.
