ForYour Safety
Follow instructions below to prevent severe personal injury, death or substan- tial property damage:
●Do not use crankcase drainings or any oil containing gasoline. See burner manual for proper fuel oil.
●Do not attempt to start burner when excess oil has accumulated in combustion chamber, when unit is full of vapor, or when combus- tion chamber is very hot.
●Do not start burner unless collector hood, flue cap, jacket cap, breeching and burner mount- ing door are secured in place.
●Never burn garbage or paper in the boiler.
●Never leave combustible material around boiler.
●DO NOT TAMPER WITH UNIT OR CONTROLS. Always follow specific instructions when starting up boiler or performing routine maintenance or service.
WARNING Follow instructions below to prevent severe personal injury, death or substan- tial property damage:
●To avoid electric shock, disconnect electrical supply to burner service switch and additional external switches before performing service.
●To avoid severe burns, allow boiler to cool before performing service.
●Do not block flow of combustion or ventilation air to boiler.
●Boiler must be connected to a flue with sufficient draft at all times to assure proper operation.
Do not use this boiler if any part has been under water. Electrical and mechanical failures may cause electric shock and fire risks. Immediately call a qualified service technician to inspect chimney or vent, boiler and burner. Have the boiler flueways cleaned and have the following replaced:
—all electrical and mechanical controls
—electrical wiring
—oil burner and controls
—insulation and chamber lining
Tips for water systems:
●Check boiler and system piping for leaks. Continual makeup water will reduce boiler life. Minerals can build up in sections, reducing heat transfer and causing cast iron to overheat, resulting in section failure.
CAUTION Failure to maintain recom- mended pH and repair leaks can cause section iron corrosion, leading to section failure and leaks. Do not use
or
●Boiler water pH 7.0 to 8.5 is recommended. For pH conditions outside 7.0 to 8.5 range or unusually hard water areas (above 7 grains hardness), consult local water treatment company.
●When using antifreeze:
-Use antifreeze especially made for hydronic systems. Inhibited propylene glycol is recommended.
Do not use automotive, ethylene glycol, undiluted or petroleum- based antifreeze. Severe personal injury, death or substantial property damage can result.
-50% solution provides protection to about
-Local codes may require
-Determine quantity according to system water content. Boiler water content is listed on back cover of Boiler Manual. Percent of solution will affect sizing of heat distribution units, circulator and expansion tank.
-Follow antifreeze manufacturer's instruc- tions.
●Do not add cold water to hot boiler. Thermal shock can cause sections to crack.
