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 inches per 3ft (5.6 cm/meter)
Lubricant

The seals and male ends of all CVent 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 as-
sembly.

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 dam-
aged, this component should not be used or an appropriate seal must be in-
stalled.

Use ONLY CVent original seals. NEVER use fabricated or non CVent
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 be-
fore 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-
CERIN© lubricant or water and assemble the components using light rota-
tional movements. Entirely insert the male end into the female end.

Inspect immediately the correct position of the seal as the system is pro-
duced 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 approxi-
mately 15° at 1/4".
