4./ VENTING

It is recommended that the chimney be thoroughly
cleaned before installation and checked for soundness
and general condition.

For proper installation, the use of a 4 inch (100 mm)
diameter gas approved chimney liner is needed. This
is to provide appropriate draft and avoid excessive
corrosion In the combustion chamber and heat ex­changer of the appliance.

Before installing the vent system, ensure that the
damper plate is locked into the open position and
secured to prevent the damper plate from crushing
the liner.
