Page 37 The gas unit needs to be dismantled to gain access to the injectors. Do this in the following manner: Lift the perforated plate up and out of the stove. Remove the reﬂector plate Loosen the four screws holding the gas unit in place.
Page 38 Now the gas unit can be lifted out carefully by tilting and rotating the unit a little. Once the gas unit has been dismounted, replace the four nozzles and adjust the three air intakes. Replace the two nozzles for the secondary burners by loosening the coupling and care- fully pulling the pipe out.
Page 39 Remove the nozzle for the main burner by loosening the coupling and carefully pulling the pipe out and then unscrewing the noz- zle. Fit the LPG nozzle and tighten the lock nut. Finally, re-tighten the coupling. Replace the nozzle for the pilot light by loosening the coupling and carefully pulling the pipe out.
Page 40 The air intake to the main burner is adjust- ed for LPG conﬁguration by loosening the two nuts and pushing the plate all the way towards the burner. (The hole fully open) The two air intakes for the secondary burn- er are adjusted for LPG conﬁguration by loosening the two screws and rotating the air intake by 90°.
Page 41 The air intakes need to be reversed therefore when the stove is conﬁg- ured for LPG. The gas unit is reassembled using the four screws. Replace the perforated plate and fully assemble the stove. See Section: Assembly of secondary burn- ers.
Page 42 Fitting of Secondary burners The burners are inserted above the pipes sticking through the perforated plate. Note that there is a right burner and a left one so it is important that they are posi- tioned as shown, i.e., that the side with the extra holes faces out the way.
Page 43 Arrangement of "Embers" and ”Logs" When layers of embers and the ceramic logs are arranged in the com- bustion chamber, it is important that the pilot ﬂame and its thermosen- sor are not covered over. And that no glowing material ﬁnds its way down under the pilot plate guard.

Page 48 Start-up Insertion of Batteries. The receiver on the stove and the remote con- trol use batteries. A set of batteries to be inserted prior to start- up is included. To access the battery box on the receiver, open the cover below the door, by pulling it towards yourself, and lifting it off.
Page 49 The batteries in the receiver must face the directions shown in the illustration. The remote control uses 2 x AA 1.5 V batteries.
Page 50 SETTING UP OF THE ELECTRONIC CODE In order for the remote control to work, it must be synchronised with the stove's receiver. A code is selected automatically from 65,000 possible codes. The stove and remote control are synchronised in the following manner.
Page 51 Commissioning Check functioning of pilot light. See User Instructions for use of remote control. 1. Start the pilot light. 2. Check that the pilot light remains ignited. 3. Turn off the pilot light. Check the functioning of the main burner. 1.
Page 52 Note. After the pressure test and removal of the manometer, the screws in the “pressure tap” should be retightened. Check the system for gas leaks.
Page 53 Initial ignition For the initial ignition, ensure that all packaging, labels etc. have been removed from the stove and that the door glass has been cleaned. Begin at low output, then the stove can be slowly turned up to a great- er output.

Page 60 FIRE OR EXPLOSION HAZARD. Failure to follow safety warnings exactly could result in serious injury, death, or pro- perty damage. Using stove without remote control. Where the remote control cannot be used, it is possible to turn on the stove manually. Always be very cautious if you chose to do this as the combustion chamber needs to be opened.
Page 61 Once the pilot ﬂame is ignited, turn the control button so that the arrow points down to (1) ON. Now the Main and secondary burners can be ignited and adjusted by turn- ing the gas valve anticlockwise above to (2) ON. The gas valve should be fully open for a minimum of 30 seconds before the ﬂames are turned down.
Page 62 Service. Turn off the stove and shut off the gas supply. Ensure the stove is com- pletely cold before starting. Rais cannot be held responsible for injuries arising from touching a hot stove. Proposed service procedure.
Page 63 MAINTENANCE INSTRUCTIONS A qualiﬁed service agency should conduct an annual inspection and maintenance of your appliance including the overall installation and venting to keep it running safely. The following procedures should be performed only by a qualiﬁed service person. The gas supply should be turned off and the stove should be completely cool whenever a maintenance procedure is performed.
Page 64 The area around the injector should be inspected and any lint or foreign material must be removed with a brush or vacuum. Pilot Injector Natural - Marking 31.2 Pilot Injector Propane - Marking 27.1 Thermocouple Maintenance The thermocouple completeness and operation must be checked. The qualiﬁed engineer must conﬁrm that the thermocouple is in place and not cracked or damaged.
Page 65 INSPECTING THE VENTING An inspection of both the inner and outer vent pipes and the vent terminal should be made as part of the annual service appointment. The venting must have no blockage and be in good repair. The vent manufacturer’s instructions may provide speciﬁc details on vent inspection.
Page 66 This is done by removing the 4 bolts holding the burner in place. Now the burner can be lifted out of the combustion chamber. Now there is free access to the nozzles. When parts are replaced, only replace these with original Rais speciﬁed parts.
