ASSEMBLY

2.1.

Assembly dimensions

The dimensions of the burner and boiler connection are ac-
cording to DIN EN 226 (dimensions in mm), see figure 7.
2.2.

Installing the burner

• Install sliding flange and seal onto the heat generator us-
ing the supplied M8 screws. The mounting screw of the
sliding flange must be turned upwards.
• Insert burner with burner pipe into the flange until the
burner pipe is flush with the inside of the combustion
chamber. Observe special instructions of the heat genera-
tor manufacturer, if any.
• Tighten the mounting screw of the flange clamp.
Caution: The flange must be oriented to ensure that the
burner is installed with the correct angle (see fig. 6).
• Install the recirculation tube.
2.3.

Service position

Loosen the service screw by 1/2 turn using a 4 mm hexagon
socket wrench (see fig. 8). Turn the burner to the left and re-
move it from the burner pipe. Then, place it in the service
position (see fig. 9).
2.4. Change of the nozzle
• Loosen screw (2) using a 4 mm hexagon socket wrench
and remove the baffle plate (1) (see fig. 9).
• Select a new nozzle according to the required perfor-
mance range (see table on page 9).
• Remove installed nozzle (3) and screw on the selected
nozzle (see fig. 9).
• Check the distance between the baffle plate (1) and the
nozzle (3) (see fig. 10).
• Install the baffle plate (1) back in place and tighten the
screw (2).
Caution: The baffle plate and nozzle could be hot!
• Control and re-adjust the ignition electrodes if necessary
(see fig. 10).
• Bring the burner in operating position and tighten the
service screw.

Nozzle table

The oil flow rate specified in the nozzle table refers to a vis-
cosity of the preheated heating oil of approx. 2 mm2/s.
2.6. Combustion chamber – minimum dimensions
According to GN 267, low-emission combustion values can only
be reached if the combustion chamber minimum dimensions
are complied with.
