    The other has a lower and upper catalyser and a flame ring, which fits on top of the upper catalyser, used on BB1, Belfort and BB2. Make sure that you know which burner you are working on; the bb1 burner is capable of generating a taller blue flame on high fire and a smaller flame on low fire.

  • Page 6: Bb1, Belfort And Bb2 Pot Sectional Drawing

    The main causes of poor oil flow are -: 1. Water contaminated diesel. 2. Boat out of trim and stove out of level. 3. Syphonic oil feed in contradiction of installation advice. 4. Air locked metering stems or oil feed pipes.

    If any one of 1 to 4 is at fault then 5 will be the result. 5. Badly carboned-: 5-1. Descaling device. 5-2. Vaporising pot. 5-3. Oil feed pipe from valve to descaller. This information is given on the assumption that the appliance has run correctly for some time and then has progressively started to run sooty.

    3. Refer to the sectional illustrations of the pots and you will note that there is a space between the inner and outer skin of the burner, on BB1 and Belfort burners this gap can be heavily contaminated with hard carbon scale.

    If the descaling lever does not rotate in a nice arc to properly clean all around the outer edge of the outlet, it could be possible that the initial setting of the low firing rate will have to be re-adjusted. The descaling device comprises of a cast brass descaler body into which is fitted a cranked descaling lever sealed via a compression nut, a small compression olive and a small circular compression seal.

    There are two types of valve, which could be fitted to the stove. Access to the low fire adjustment is different; make sure you know which valve you are working on. On the OCI ships valve the plastic drive knob has to be removed to gain access to the low fire screw.

    13. Adjust the high fire screw by half a turn in and try turning the fuel flow up, if it is still fuel rich repeat the process until the hire fire flame is running blue with flicks of yellow in the tips.

    (Setting 3 on the fuel flow control knob) and let it stabilize. Allow at least half an hour for the chimney to warm up thoroughly before making any adjustments to the high or low fire screws. Turn the stove down onto minimum firing rate and let it stabilize. After stabilization the catalyser should be glowing dull red with wispy blue flames suspended off the top of it, just level with the top of the pot.

    NOTE 1. It will not be possible to reset the stat until the water temperature has dropped. NOTE 2. Details on adjustment of the operating and safety stat can be found in the appliance installation details, or in the commissioning routine. Every 12 months 1.

    (550 mm sq per kW of appliance rating.) As required, carry out an oil line inspection. Clean or change the oil tank filter every year or as required, we have found that paper filter cartridges can absorb moisture and freeze in cold weather creating oil flow problems.

  • Page 20: Fault Finding

    To assist with servicing and fault finding we categorise problems under the headings listed. (See Pre Amble notes) 1. Fuel contamination problems 2. Fuel type and quality problems 3. Fuel feed problems Air is drawn into the burner by the action of the chimney. THE POWER, (suck or vacuum the chimney can develop) depends upon the following-: THE HEIGHT.

  • Page 21: Commissioning Problems

    (See Pre Amble notes) Commissioning, or lack of it, is the biggest single problem associated with alleged faults on Bubble stoves. If the plumbing circuit is not of a suitable design, it will not be possible to carry out the commissioning procedure as the burner may well shut down due to overheating of the boiler.

  • Page 22: Flue Vacuum

    NOTE. On new installations, it is not unusual for an air bubble to restrict the flow of oil through the metering stem in the oil control valve. To cure this problem gently tap the valve with a plastic handled screwdriver or agitate the oil in the float chamber to try and break the meniscus lock created by the air bubble.

  • Page 23: Check For Oil Leaks

    Is there oil in the fuel tank? Has the fire valve tripped? Has the isolation valve been accidentally turned off? Is the oil turned on at the oil flow control knob on the valve? Has the level of the oil valve been disturbed? The oil level mark on the side of the oil control valve should be set at 20mm from the bottom of the pot, check this out using a rule or height gauge.

  • Page 24: Burner Flares Up During Ignition

    If the burner flares up during the ignition cycle, this is normally caused by allowing too much fuel into the pot before the flame has had the time to come up to establish at vaporisation temperature. The other cause of this is the burner being out of level and the incoming fuel running away from the lighting port and forming a pool opposite the lighting port.
