Polypropylene (PP) Common Venting Installation Instructions 33

A6 General Assembly Instructions

Correct Pitch

The pipes and formed parts must be installed at an angle of 3° incline towards

the heating appliance, to allow the condensate to dispose in accordance with

regulations.

Note: 3° Pitch equals a height difference of 2” per 3 ft (5.6 cm/meter)

Lubricant

• The seals and male ends of all common vent components must be

lubricated before assembly. Use ONLY CENTROCERIN© lubricant or

water to aid in the assembly of these vent components.

• Apply a thin layer of CENTROCERIN© lubricant to each seal before

assembly.

• A tube CENTROCERIN© lubricant is packed with every kit assembly and

available for separate purchase.

• 1 tube of CENTROCERIN© lubricant is sufficient for a 100ft common

header installation

Flow Direction

• The female end of the components in contact with the flue gasses must

always point in the direction of the termination.

• It is imperative to maintain this flow direction for proper condensate flow

and integrity of the seal/gasket.

Seal Direction and Assembly of Seals

Seals are pre-assembled in the vent components. If a seal is missing or

damaged, this component should not be used or an appropriate seal must be

installed.

• Use ONLY original seals. NEVER use fabricated or non common vent

seals.

• Use only the appropriate nominal width and diameter seals.

• Confirm seal is installed in the appropriate direct (see figure)

• Seal and Seal Chamfer must remain clean and free of foreign debris

before assembly.

Joining, Disconnecting, Shortening and Chamfering

For measuring purposes the seals can be removed from their chamber.

Note: always reassemble the seals in the right direction, as indicated in the illustration.

• Lubricate the seals and/or male ends of the components with CENTRO-

rotational movements. Entirely insert the male end into the female end.

• Inspect immediately the correct position of the seal as the system is

produced out of translucent material

• Pipes are always shortened on the male end. Never cut or modify formed

vent components such as elbows or collectors.

• Cut straight ,perpendicular to the tube and chamfer the edges

approximately 15° at 1/4”.
