ForYour Safety
Follow instructions below to prevent severe personal injury, death or substantial 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 combustion chamber is very hot.
●Do not start burner unless collector hood, flue cap, jacket cap, breeching and burner mounting 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.
Follow instructions below to prevent severe personal injury, death or substantial 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.
Failure to maintain recommended pH and repair leaks can cause section iron corrosion, leading to section failure and leaks. Do not use petroleum-based sealing
or stop-leak compounds in boiler systems. Damage to system components can result, causing property damage.
●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 petroleumbased antifreeze. Severe personal injury, death or substantial property damage can result.
-50% solution provides protection to about -300F.
-Local codes may require back-flow preventer or actual disconnect from city water supply.
-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 instructions.
●Do not add cold water to hot boiler. Thermal shock can cause sections to crack.

Routine Maintenance Schedule
The schedule below is specifically designed for the homeowner. Please read pages 2 and 3 before proceeding.
Beginning each heating season:
Call a qualified service technician to perform annual service.
Daily during heating season:
Check that boiler area is free from combustible materials, gasoline and other flammable vapors and liquids.
End of heating season:
If tankless heater is installed, boiler will continue to operate. Check for the following:
-All daily and weekly instructions listed on this page must be followed.
-Burner motor may have to be oiled. Some motors are permanently lubricated and do not need additional oil. Check for oiling instructions on burner or motor.
Weekly during heating season:
Check for and remove any obstructions to flow of combustion or ventilation air to boiler.
Check that breeching is attached between boiler and chimney. If breeching is loose or damaged, immediately turn off switch on boiler and call service technician to repair.
Check for oil leaks in oil piping and around burner. If found, immediately call qualified service technician to correct situation.
Check for water leaks in boiler and piping; also check for leaks around tankless heater plate, if installed. If found, immediately call service technician to repair.
Boiler shutdown:
Do not drain boiler unless exposure to freezing temperatures will occur.
Always keep manual fuel supply shut off if burner is shut down for an extended period of time.
a.Turn off switch at boiler and any external switch to boiler.
b.Close fuel valves.
c.Turn off water feed valve.
d.Cover burner to protect from dust and dampness.
