The internal cross-section of the exhaust pipes should be smoth and all connections
must be hermetically sealed. Avoid as much horizontal mounting as possible.
Horizontal parts should have a slope of at least 3% upwards. The length of the
horizontal part of the saddle shall be minimum and in any case not more than 2 meters
with the possibility of cleaning and removing the accumulated ash.
The connection to the chimney should be made with a maximum of two exhaust pipes.
For stove operation, a constant negative pressure is required. At reduced power, the
flue gas temperature is low and condensation may occur. It is therefore important that
the chimney is well insulated.
The flue pipes should be made of non-combustible materials that are suitable and
resistant to combustion products and their possible condensation. In any case, the
parts or zones that are flammable, must be properly protected, such as wooden boards
or beams.
FOR SMOKE PIPES, DO NOT USE METAL-FLEXIBLE CABLES. ALL
PARTS OF THE SMOKE PIPE SHOULD BE SAFE AND REMOVABLE TO
CLEAN CLEANING. AVOID HORIZONTAL DEVIATIONS.
