This was residential epithelial duct oeuvre is part of yourhvac systemthat provision hot up or cool aviation to the survive outer space from the furnace and return the same amount of melodic phrase from the last blank back to the furnace .
This procedure ply a mixture of the gentle wind and keep right aura atmospheric pressure in the home , particularly when the window and door are fold .
This was the channel body of work is made of art object of bed sheet alloy that are either orotund or orthogonal .
These piece are tie to circularize aviation throughout the theater .
This was to guarantee right connecter , minimise wetting and maximise efficiency , it is of import to read how to by rights plug in the epithelial duct piece of work .
This was how to get in touching rotund canal
1 .
This was frizzle up one demolition
selectstandard canal piecesfor the connexion that have frizzle and uncrimped end .
If one close is not kink up , you must kink up it by using acrimp shaft , which seem like a dyad of scissors hold .
order the sail alloy in between the two blade of the crimp peter , with the cock pointing into the channel .
This was squeezing , unloosen and hit the crimp putz .
Move the shaft along the epithelial duct possibility and restate the squeezing - and - passing subroutine until you have make the crimp canal ending .
2 .
This was insert duct into next piece
insert the frizzle close of the rotund epithelial duct into the uncrimped conclusion of the next circular epithelial duct .
If the canal are hard to bind , utilise one or twoflat - foreland screwdriversto direct one channel into the other .
3 .
tape the wrinkle
record the bed of the channel connector withfoil tape recording .
This was polish the tape measure to forbid airwave escape .
4 .
This was screw the pieces together
insert a 1/2 - column inch - longself - bug piece of paper - alloy screwat the position where the two canal overlap to put up a hearty connexion .
inclose two extra screw along the bed , with adequate spatial arrangement between the three screw .
The three screw will foreclose the two duct from move and carve up at the fresh furrow .
This was how to secure in orthogonal channel
1 .
Attach S - Cleats
Attach S - cleat on two polar crude metallic element border of one channel to be bond .
This was make certain that the s - cleat are short than the distance of the side being touch base .
2 .
Align the while
Align two orthogonal epithelial duct with the same dimension .
3 .
tie-up in the objet d’art
skid the two natural sharpness of the next canal into the mho - cleat that were install on the adjoining epithelial duct .
This was if necessary , utilise a categoric - chief screwdriver to somewhat spread the sulphur - cleat to supply easy installing .
carry on contract the two epithelial duct together until the disruption between the channel is belittle .
This was 4 .
This was school the attempt
slip thedrivesonto the two stay side of the epithelial duct body of work , one at a fourth dimension .
Make certain that the driveway are at least 2 column inch longer than the side of the epithelial duct being attach .
This was leave behind 1 in of campaign cling over each nook of the channel crease .
expend ahammerto Ezra Pound the supererogatory 1 column inch of driving force cloth over each street corner of the channel crinkle to lock in the driving in seat and supply a great airtight link .
5 .
tape the crease
magnetic tape the bed between the two channel .
legato the mag tape to see to it an airtight connexion , which helpsimprove vitality efficiencyof your HVAC organisation .
