Cold air returns, crawlspaces and the underside of staircases will serve as accessible

spaces, through which the main run can pass.

"B-Vent" shafts can also be used to bring the main run from one story to the next

(illustration 6). Consult your local building code first, as in some cases metal pipes

must be used for "B-Vent" installations.

It is important that the low-voltage wire be fastened to the branch line as it must be

fed through at the same time as the pipe.

Install all the branch lines in the same manner, making sure that enough length of the

branch line pipe protrudes above the plate for connection to the main line fittings.

Gaining acces to pipe run through carpeted floor

Pull carpet from tackstrips. Roll back carpet and carpet padding to expose the area

under which you intend to run the pipe. Pull out all nails in this area with which the

underfloor has been fastened to the floor joists. Using a portable circular skillsaw, cut

along the nail holes, along the center of the floor joists, setting the blade so it cuts

completely through the underfloor. At each end of both cuts, cut at right angles to

these cuts until the uncut portion of the floor can be completely lifted out, leaving

an opening that allows you to work freely between the floor joists. After you have

completed your work, insert the cut-out panel back into the opening and nail down

into joists; preferably at a slight angle towards the center of the joists to avoid missing

the joists. Spread the carpet padding back into place and stretch the carpet back onto

the tackstrips.

With all the branch lines connected to the

main line continue to install the main line

to the power unit using pipe straps at

approximately 8' intervals.

Connect pipe and low voltage wire to power

unit. Plug power unit into a nearby receptacle.

YOUR CENTRAL VACUUM IS NOW OPERATIONAL.

NEW CONSTRUCTION ROUGH-IN

Main system installation

The ideal time to install the system is before dry-walling. We recommend to hold off

the installation until all furnace ducts and plumbing rough-in are completed, as it is

easier for you to work around these ducts and plumbing lines than for the sub-trades

to work around you. Ideally, the main run should be run along the center of the house

from the basement up.

As the location of the furnace is usually in the center of the house with the heating

ducts branching out from there, your main run could easily be installed along these

ducts. Your system's main run will then be concealed at the same time as

furnace ducts and plumbing-lines are boxed-in and covered.

TRY TO COORDINATE SUB-TRADES AS MUCH AS POSSIBLE.

If your home is being built by a contractor, be sure to inform him of your

intentions, as this is an ideal time to request the installation of a separate circuit

to insure sufficient power supply for your system.

The rough-in installation is much simpler and faster than the previously described

installation for finished construction, as the entire working area is still fully exposed

and readily accessible.

For the inlet valve installation follow steps 3 and 4 of the mounting plate installation

diagram. When you are ready to install the power unit, follow the same power unit

"hook-up" procedure as per previous section.

When the rough-in is completed, leave sufficient L.V.T wire and pipe protruding

near the intended power unit location so that the final connection to the power unit

can be made easily and quickly without creating extra work when power unit is

installed.

On the top surface of the inlet kit boxes you will find a plaster guard and a mounting

plate template. Simply cut along the dotted lines and use the template to scribe the

exact opening for the mounting plate.

In order to prevent construction debris from entering the installed mounting plate,

firmly push plaster guard into mounting plate as per illustration 3 of the mounting

plate.

The increased use of 2x3 wood and metal studs in north american construction

methods demands fittings compatible with these building industry standards.

Our 2021 HXS has been specifically designed for such purposes.

The 2021 HXS differs from the "short 90° Ell" in that it has only 1/4" hubs at the moun-

ting plate end and features a pipe spigot at the other end. The vacuum pipe can be slid

over and glued to the spigot as the outside diameter of the spigot corresponds with the

inside diameter of the vacuum pipe.

Simply glue to back of the mounting plate as you would any other fitting.

The 2021 is not included in kits, but is available from your dealer.

Second story inlet take-off from attic to basement drop.

A) For confined wall space. Although not included in a kit, this special short tee is

available from your dealer for 2" x 4" and 2"x 3" stud walls.

B) If space is available, use the fittings as shown in this diagram.
