8 PLUMBING, AIR SUPPLY, VENTING, GASSUPPLY AND ELECTRICAL WORK ARE AS BOILER REPLACEMENTI nstallation as boiler replacement on an old system with largewater volume may experience condensation within the boiler oncold starts. This condensing of Water vapor in the combustionarea can be prevented if a portion of the system Water flow isdiverted past the boiler to cause an increase in boiler old systems where Water temperature can be expected todrop appreciably due to long standby periods, a bypass pipe of atleast 1" size with a balancing cock should be installed betweenthe boiler inlet and outlet. When the system first starts, the valveshould be slowly opened until the condensing ceases. Thisadjustment remains at a permanent setting to establish requiredtemperature rise across the equipment shall be installed in accordance with thoseinstallation regulations in force in the local area where theinstallation is to be made.

9 These shall be carefully followed in allcases. Authorities having jurisdiction shall be consulted beforeinstallations are installing the boiler, consideration must be given to properlocation. Location selected should be as close to the stack orchimney as practicable with adequate air supply and as centralizedwith the piping system as possible. This location should also besuch that the gas ignition system components are protected fromwater (dripping, spraying, etc.) during appliance operation andservice (circulator replacement, control replacement, etc.).THE BOILER MUST NOT BE INSTALLED ON BOILER SHOULD NOT BE LOCATED IN AN AREA WHERE ITWILL BE SUBJECT TO IT NEAR A FLOOR DRAIN. THE BOILER SHOULD BELOCATED IN AN AREA WHERE LEAKAGE FROM THE BOILER ORCONNECTIONS WILL NOT RESULT IN DAMAGE TO THEADJACENT AREA OR TO LOWER FLOORS OF THE SUCH LOCATIONS CANNOT BE AVOIDED, A SUITABLEDRAIN PAN SHOULD BE INSTALLED UNDER THE BOILER.

10 Suchpans should be fabricated with sides at least 60mm (2-1/2") deep,with length and width at least 50mm (2") greater than the diameterof the boiler and must be piped to an adequate drain. The panmust not restrict combustion air flow. WARNINGKEEPING BOILER AREA CLEAR AND FREE FROM COMBUSTIBLEMATERIALS, GASOLINE AND OTHER FLAMMABLE VAPORS ANDLIQUIDS. WARNINGTHERE IS A RISK IN USING FUEL BURNING APPLIANCES SUCHAS BOILERS IN ROOMS OR AREAS WHERE GASOLINE, OTHERFLAMMABLE LIQUIDS OR ENGINE DRIVEN EQUIPMENT ORVEHICLES ARE STORED, OPERATED OR VAPORS ARE HEAVY AND TRAVEL ALONG THEFLOOR AND MAY BE IGNITED BY THE IGNITER OR MAIN BURNERFLAMES CAUSING FIRE OR EXPLOSION. SOME LOCAL CODESPERMIT OPERATION OF GAS APPLIANCES IF INSTALLED18 INCHES OR MORE ABOVE THE FLOOR. THIS MAY REDUCETHE RISK IF LOCATION IN SUCH AN AREA CANNOT BE AVOIDED. WARNINGFLAMMABLE ITEMS, PRESSURIZED CONTAINERS OR ANYOTHER POTENTIAL FIRE HAZARDOUS ARTICLES MUST NEVERBE PLACED ON OR ADJACENT TO THE BOILER.
