General Instructions for the Installation of AIC-approved Chimney Components

Make sure to insulate the

fl ue piping in damp rooms

to avoid condensation water

from forming and dripping.

Cut the pipes squarely and deburr the

edges. This will ensure correct sealing

and prevent seals from being damaged.

To ease the assembly of pipes, use exclu-

sively a mixture of water and soap (1%)

on the extremity of the pipe to be fi t in.

Metal fl ue pipes should always be fi t-

ted into the sleeve to the end stop.

Installing the pipes - General principles

Flue pipe elements or PP air

inlet elements should not be

screwed together.

Piping elements should not be bond-

ed together using glue (e.g. silicone) or

foam (e.g. PUR).

Plastic fl ue pipes should be

allowed to expand under the

eff ect of heat. Leave about

10 mm between the pipe and

the sleeve end stop.

he fl ue system should be fi tted with an

inspection opening.

Do not exceed the maximum length rec-

ommended for the product when con-

necting the fl ue pipes, or the system pow-

er might decrease.

or C-type appliances, the fl ue gas exhaust

pipes must at least comply with the cate-

gory T120 H1 W1/2 O30 LI E U when using

parallel piping and T120 H1 W1/2 O00 LI/

LE E U0 when using concentric piping (EN

14471). Metallic piping must comply with

the requirements of standard EN 18

56.

The maximum length of duct must be

calculated according to the permissible

diff erence in pressure indicated in the

technical specifi cations.
