14.12 The gas pressure control device ( Picture 4 )
Adjustment: 10 mbar
14.13 Basic adjustment of the gas burner
14.13.1 Gas pressure:
Initial position: Turn the pressure regulating screw to the left up to the limit stop.
Natural gas L : ca. 7-8,8 mbar (30 rotations to the right).
Natural gas H : ca. 7,5-8 mbar (18 rotations to the right).
Liquefied gas : ca. 6-6,3 mbar (12 rotations to the right).
The pressure measurement should be tapped from No. 5 (page 11, picture 3).
14.13.2 Quantity of air: Place the gate valve in such manner, that approx. 2/3 of the intake stays free.
14.13.3 Please see data sheet page 17 for the adjustment of the electrodes and baffle plate!
Attention: The basic adjustment only serves to take the burner into operation.
After that the correct adjustment must absolutely be carried out by means of a flue gas tester.
14.14 Tighten heating coils nuts
After 50 operating hours the nuts of the heating coils have to be tightened again, as the heating coil can gravitate in
the oxid ceramic disc. Especially when operating in mobile areas.
15. The gas firing automat type Siemens
a. Observation of the air and gas pressure.
b. Observation of the flame by means of the ionization current.
c. Observation of the burner motor and the gas valve.
(see attachment page 31-36)
16. Adjustment data for the combustion chamber BR1000G
16.1 Gas burner
The factory carries out the adjustment of the gas burner regarding the distances of the electrodes and the baffle plate
according to drawing page 17.
This fixed adjustment must absolutely not be changed under any circumstances.
16.2 Heating capacity and modification of the gas type
The heating capacity of the burner can be varied between 45 and 70 KW. If the heating capacity and the gas type are being
modified, only the quantities of gas and air have to be changed accordingly. These adjustments should be carried out by
well trained personnel only.
16.3 Regulation- and safety devices in general
The BR1000G Gas is equipped with the following regulating and safety devices:
Description
Barometric pressure cell for gas
Barometric pressure cell for air
Gas pressure switch
Regulator of gas quantity
Water-flow switch
Water-pressure switch
Exhaust temperature limiter
Digital(Thermostat)
Safety valve
Each maintenance and service should include the verification and – if necessary – the re-adjustment of the values.
