SECTION D – PIPE & FITTING JOINT

ASSEMBLY

The ends of each inner pipe are made of flanges (1/2"). All the

joints between sections are a flange-to-flange connection of

the inner pipe.

SPECIAL FEATURE

All sections have an unattached "Alignment Sleeve".

The alignment sleeve facilitates centering of adjacent sections

and provides backing for the sealant applied to the flange

keeping the sealant in the intended location. Typically, it is

inserted in the downstream end but may be removed.

Although not required, it aids in easier assembly, better sealing

and adds strength to the section joint

STEP 3:

Join the two flanged ends of the duct section together and

rotate slightly to ensure complete coverage of the sealant on

flanges.

STEP 4:

Install the V-band around the flanges making sure the flanges

are located within the V-Clamp.

NOTE: do not locate V-band hardware at the bottom

side of horizontal ducts

NOTE: light tapping with a hammer all around the

band while tightening bolts helps align and pull

flanges together.

STEP 5:

Install the supplied AES insulation strips between sections to

ensure that all gaps are filled. Be sure that insulation is tightly

packed and completely fills the void between flue and closure

band when assembled
