1. Insert adjusting screws E into the base rails.

Note

The adjusting screws and sight glass closure can

be found inside the combustion chamber.

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").

Adjustable anti-vibration feet

Insert adjustable feet into the base rails from below.

By resetting bolts A the door can be hinged on the

right.

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.

Combustion chamber sight glass

Mounting the combustion chamber sight glass

The sight glass casing with accessories is supplied

inside the combustion chamber.

Changing the boiler door opening

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.

1. Check that the plug is a precise fit. If necessary,

enlarge hole in insulation block.
