If the chimney is cooled by lack of insulation the difference in weight will also decrease the natural draught. The cooling of the chimney can vary a lot, amongst other things depending on the wind A bad chimney can create the following effects: 1. Pressure fluctuations at start up that create overpressure in the combustion chamber and possibly exhaust gases and soot in the room and top oven. 2. A smoky flame during the time necessary to heat the chimney until the natural draught has stabilised. 3.
This guide is to help you install the Pressure Jet oil burner into an existing Rayburn 200 series cooker. It is ONLY designed to fit the models originally made for OIL or GAS operation and is NOT SUITABLE for the 4 door solid fuel variety. It may be fitted into the OF7 Regent - please ask for advice. Preparation Tools required Vacuum , hand brush ( paint brush) , bottle brush etc Sabre saw, hacksaws ( metal blade) Electric drill with drill bits to tap to 6mm ( 5.5mm bit) Metal file Fireclay – 1 kilo tub.
Frame cut through, ready to break off. No damage to front casting! Once the frame is cut through – careful not to saw the enamel front- unscrew the 2 bolts located under the frame. They can easily be felt under where you have been sawing. They unscrew easily with a screwdriver about 8mm across the blade. Gently tap the frame on the inside end ( both sides) and I have found it snaps easily and cleanly . Vacuum out the area underneath to stop swarf from being sucked into the burner.
Drilling the Oven to take the heat sensor Thermostat Capillary = 6 mm 150 mm You may now drill the hole to take the oven sensor. It should be drilled at a 45 degree angle about 20 mm in from the frame up into the oven. The hole will come out inside the oven, behind the side wall ( which can be unscrewed if you wish – 2 ¼” Whitworth bolts hold the side wall in place) Don’t drill too close to the frame as it makes removing the sensor more difficult .
Now fit Part 3 the 50 mm x Rope Seal around the ceramic block to seal the air. It should project up the front edges as in photo. Ensure that it is pressed tightly into position Then take part No.4 the blanket with a large hole in the centre and fit into position as in photo. The 2 equal side face the oven and outer wall of the cooker. see photo. Then press the blanket outwards to fill all the gaps but try and keep the hole equal around the blast tube.
Fit the cast iron baffle into position with the front markings facing forward. Then place the top side insulation pad part No. 8 into position, pressing it in tightly. Now press the Top Front Insulation Pad Part No. 9 tightly into position. Press the top edges of the blankets back as far as possible so as not to restrict the air passage-ways under the hot plate. Now glue the Hot Plate 15 mm seal part No. 10 into position with the tales at the cool end of the hot plate, ensuring that it seals correctly.
Bleeding the oil pipe. There is a small bleed fitting on the pump - see photo. 50 mm to left of oil pipe connection with thumb nut. Connect 1/8* diameter bleed tube supplied and feed into a jar. Connect oil pressure test gauge by removing knurled nut (with recessed Allen key head at top of pump) .Bleed oil through from line. Its important to bleed both sides of the pump as air can get trapped in the pump and create noise. Once bled, shut off thumb nut. Firing the burner.
Current legislation insists that burners are set up using Combustion Testing Equipment. In order to obtain the best performance from the burner and cooker these units must also be set up using testing equipment. As there is no ideal testing point in or on the cooker it is necessary to do this in the flue above the Flue Box. Therefore drill a hole in the flue suitable for the test probe. Before firing the burner to test the combustion put a plug in the vent hole in the top oven.
