1. All controls have been set at the factory and should require no adjustments MODIFICATION MISUSE Any modification or misuse of this unit could result in a dangerous situation Reimers is not liable for any product that has been modified or improperly used REGISTRATION Most states cities require boiler registration inspection Check local regulations REPAIR Repair of this unit must be attempted only by experienced personnel See Enclosed WATER All boilers must be blown down periodically to remove minerals scale and other foreign matter which accumulate inside the pressure chamber The concentration of this deposit depends in part upon the condition of the water in the area When water if naturally soft or has been softened chemically blowdowns are required less often than in areas where hard water is found Water softeners are suggested in hard water areas to minimize the formation of hard scale on heating elements Another factor affecting water condition is the amount of condensate if any that is being returned to the boiler Since condensate is essentially clean distilled water it contains very few impurities If a large part of the condensate is being returned and little make up water is used the boiler need not be blown down as often as when little or no condensate is returned to the boiler Chemical water treatment is not recommended for this design of electric boiler For details contact a water softening company in y2. 4 18 24 18 HLR 60 108 18 24 18 24 24 CONTROL HLR 125 210 18 24 18 36 36 HLR 225 500 18 36 18 46 18 55555555555 DESCRIPTION OF DIMENSIONS amp SYMBOLS A CLEARANCE ABOVE TOP OF BOILER B CLEARANCE FROM FRONT OF BOILER PREFIX C TO NUMERAL INDICATES SUITABILITY FOR CLOSET OR ALCOVE INSTALLATIONS PREFIX A INDICATES SUITABILITY FOR ALCOVE BUT NOT FOR CLOSET D CLEARANCE FROM BACK OF BOILER EL CLEARANCE FROM LEFT SIDE OF BOILER ER CLEARANCE FROM RIGHT SIDE OF BOILER F INDICATES TYPE OF FLOORING NC FOR NONCOMBUSTIBLE C FOR COMBUSTIBLE NUMERAL INDICATES MINIMUM CLEARANCE BELOW SUSPENDED UNITS TO COMBUSTIBLE FLOOR NOTE IMPORTANT THE ABOVE DIMENSIONS DO NOT TAKE INTO CONSIDERATION THE PERIODIC NEED TO REMOVE THE HEATING ELEMENTS FOR THESE ALLOWANCES PLEASE REFER TO PAGE 1 ITEM 1 OF INSTALLATION INSTRUCTIONS
