Recommended wall clearances
Observe the recommended wall clearances for easier
boiler installation, cleaning and maintenance. Adhere to
the minimum clearances (in brackets) in all cases.
Take into account the space required for opening the
burner door.
The burner door can be hung on the right or left.
The wall clearance on the hinge side must be at least the
same as the amount by which the burner projects (AB).
Recommended wall clearance AB + 100 mm.
If you do not observe the recommended minimum wall
clearances, you will not be able to use the cleaning set
(accessory) to clean the boiler. As an alternative, we
recommend using shorter (approx. 1 m in length)
mountable cleaning devices or wet cleaning.
