5.23 Fitting burner (accessory) and

connecting gas supply

This chapter explains how to fit a burner.

B

A burner that is made dirty by building work must be
cleaned before being commissioned.

5.23.1 Fitting the burner plate

A burner plate without pre-drilled holes is included with
the boiler.

If you have not ordered the predrilled burner plates from
Buderus, the enclosed blanking plate will have to be
machined accordingly onsite.

B

Drill or cut the burner plate to match the required blast
tube diameter.

B

Drill holes for fastening the boiler using the burner
connecting flange as a template.

B

Fasten the burner plate to the burner door using the
hex-head bolts and washers (seal with gasket).

CAUTION:

System damage from incorrect

burner!

B

Only use burners that meet the technical
requirements of the Logano plus SB615
Gas boiler.

CAUTION:

Damage to system through

incorrect burner adjustment (overloading)!

B

Make sure that the value set does not
exceed the combustion heat output
Qn (Hi) stated on the rating plate.

Do not work on the burner plate when
installed.

Predrilled burner plates are available from
Buderus upon request (accessory).
