10. Accessories

10.1 Measuring adapter MA 2

For the easy measurement of photoelectric current for burner adjustment
and/or troubleshooting, we recommend the use of a special measuring
adapter MA2 (order no. 10042.00010).
The MA 2 measuring adapter is connected between the connector of the
photo conductive cell. The measuring cables of the adapter are sufficiently
long and can be directly and easily connected to the amperemeter.
10.2 Knurled-head screw for dismantling the
diaphragm valve
For the easy disassembly of the diaphragm valve from the oil pre-heater,
we recommend the use of a special knurled-head screw (order no.
10023.00026).

10.3 Portable pump tester

For de-aerating the intake pipe as well as for measuring the injection /
intake pressure of the pump, we recommend the instruments from our
portable pump tester (order no. 10042.00001).
It includes:
1 Case coated with foamed material
2 Pressure gauge (0 - 25 bar)
3 Vacuum gauge (-1 - 0 bar
4 Flexible pressure gauge extension with
1/8" screw-in nipple
5 De-aeration device 1/8" with shut-off
6 Reducing adaptor with 8 x 2mm O-ring
7 Reducing adaptor for pressure gauge
with 8 x 2mm O-ring

10.4 Intake silencer

For operation dependent on ambient air, the protective cover at the blower
inlet can be replaced by a intake air silencer which is available as an
accessory (order no. 10003.00167). The sound-reducing internal shape in
combination with the noise-absorbing lining of the intake silencer allows
for the effective reduction of the intake air noise. Due to its flat design, the
silencer can also be used when the hood is installed. The intake silencer
can be installed in the factory or using the conversion kit (order no.
10003.00167) mentioned below.
It includes:
1 Cylinder head screw with SW4 hexagon socket
similar to DIN 912 M4x50
2 Intake silencer
3 Insulating foam, inside
4 Insulating foam, outside

10.5 Sliding flange with additional O-ring sealing

In order to meet utmost requirements regarding odour escaping from the
interface between burner and heat generator, we recommend the use of
a sliding flange connection with additional O-ring sealing. In order to
achieve utmost tightness, the standard flat sealing for the boiler is
supplemented by an additional O-ring sealing. The O-ring sealing can be
installed in the factory or using the conversion kit (order no. 10003.00172)
mentioned below.
The conversion kit includes:
1 Sliding flange for burner
