Installing the compact thermal module
a
Danger!
Risk of death and risk of damage caused
by hot flue gas!
If you do not renew the seal and the self-
locking nuts on the burner door, hot flue
gases may escape and cause personal
injury and material damage.
>
Replace the seal each time you open the
burner door.
>
Replace the self-securing nuts each time
you open the burner door.
>
If the burner flange insulation on the
module shows signs of damage other
than small cracks it must be replaced
(article number 193 595).
