2. Level the boiler horizontally. No special founda-
tions are required.
Note
We recommend siting the boiler on adjustable anti-
vibration feet C (see chapter "Clearance dimen-
sions").

Danger
The heavy boiler door can cause injuries.
Secure the boiler door to prevent it from tipping
over. Wear protective clothing.
During installation observe the following:
When the boiler door is closed, sealing frame B must
press centrally onto gasket D of the boiler door (see
detail). Align mounting bracket C if required.

2. Only for burners with ventilation connection:
Connect plastic hose A with the sight glass and
the fan part of the burner (test port for "static
burner pressure").
Closing off the sight glass aperture on burners without ventilation connection
On burners without ventilation connection for sight
glass, the sight glass aperture in the boiler door is
closed off with a plug. The sight glass only serves to
cover the aperture.
Danger
When working with high temperature insulating
materials that contain zirconium or aluminium
silicate ceramic fibres, fibre dust may
develop. This fibre dust can be harmful to
health.
Only trained personnel may adjust or replace
the insulation. Wear suitable protective clothing,
especially breathing equipment and safety gog-
gles.
