ERRORS AND/OR OMISSIONS MAY OCCUR IN THE DRAWINGS, DO NOT HESITATE TO CONTACT ME SO THAT THE ERRORS/OMISSIONS CAN BE RECTIFIED. ADDITIONAL NOTES ABOUT THESE DRAWINGS: BEFORE STARTING: THE BOILER AS SHOWN ON THESE DRAWING SHOULD BE INSPECTED BY AN AUTHORISED PROFESSIONAL ENGINEER. THE RUNNING AND MAXIMUM BOILER PRESSURE TO BE CALCULATED. MAKE SURE THAT THE BOILER FULLY COMPLIES WITH THE LOCAL RULES AND REGULATIONS OF MODEL BOILERS. A COMPLIANCE AND TEST CERTIFICATE SHOULD BE OBTAINED. THE FOLLOWING APPENDAGES ARE NOT SHOWN ON THESE DRAWINGS: 1) WATER LEVEL GAUGE 2) SAFETY VALVE 3) PRESSURE GAUGE. 4) REGULATOR. IF THE ABOVE APPENDAGES ARE REQUIRED, BY REGULATION, FOR THIS BOILER, THEN THE BUILDER TO DESIGN AND INSTALL, ON THE BOILER, THE APPROPRIATE NIPPLES TO ACCOMMODATE THE REQUIRED APPENDAGES. THE APPENDAGES EITHER TO BE DESIGNED AND BUILD BY THE BUILDER OR PURCHASE AS A PROPRIETY ITEM. THE SUPPLY STEAM IS DIRECTLY TAKEN FROM THE STEAM IN THE BOILER INTO THE SPOOL VALVE CYLINDER. IF A REGULATOR IS FITTED THE BUILDER TO DESIGN AND FIT PIPING AS REQUIRED FOR THE WORKING OF THE REGULATOR. NOTES: THIS DESIGN IS BASED ON DRAWINGS/SKETCHES/PICTURES WHICH WERE FOUND ON THE INTERNET. SOME OF THE COMPONENTS ARE OF MY OWN DESIGN FOR THE EASE OF MANUFACTURE.
