Service(continued)

Also Refer to Additional Instructions Shipped With The Boiler For Specific Control Operation and Troubleshooting. Verify Proper Operation After Servicing

Your boiler should be inspected, cleaned and, if necessary, adjusted once a year. A qualified service agency should be called.

To avoid personal injury, before servicing:

1.Disconnect electrical supply.

2.Shut-off gas supply.

3.Allow boiler to cool.

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.

To avoid personal injury, death or property damage, keep boiler area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

Do not block flow of air to boiler. Incomplete combustion and flue gas spillage can occur.

Do not store sources of hydrocarbons (i.e., bleaches, cleaners, chemicals, sprays, paint removers, fabric softeners, etc.) in boiler area. This can contribute to shortened boiler/vent system life.

Suggested minimum service schedule for qualified service

technician only

Beginning of each heating season:

1.Annual service call by a qualified service agency.

2.Check burners and flueways and clean if necessary. Reference “Clean Boiler Heating Surfaces” and “Cleaning Main Burners,”page 21.

3.Visually inspect base insulation.Reference“Inspect Base Insulation,”page 17.

4.Follow procedure“To Place in Operation,”page 17.

5.Visually inspect pilot and burner flames. Reference “Check Main Burner Flames”and“Check Pilot Burner Flame,”page 21.

6.Visually inspect venting system for blockage, deterioration or leakage. Reference “Inspect Venting System,”page 21.

7.Check operation of low-water cut-off, if used, and additional field-installed controls. Refer to manufacturer’s instructions

8.Checkthatboilerareaisfreefromcombustiblematerials, gasoline and other flammable vapors and liquids.

9.Check for and remove any obstruction to flow of combustion or ventilation air.

10.Follow instructions on circulator to oil, if oil lubricated. Over-oiling will damage the circulator.Water lubricated circulators do not need oiling.

Daily during heating season:

1.Checkthatboilerareaisfreefromcombustiblematerials, gasoline and other flammable vapors and liquids.

2.Check for and remove any obstruction to flow of combustion or ventilation air.

Periodically during heating season:

1.Checkrelief valve.Referencemanufacturer’sinstructions on relief valve tag.

2.Test low water cut-off, if used. Blowdown if low water cut-off is float type. Reference manufacturer’s instructions.

Monthly during heating season:

1.Check for leaks in boiler and piping. If found, repair at once.

Continuous use of make-up water can damage boiler sections due to addition of minerals. Do not use petroleum based stop- leak compounds - leakage between the sections will occur.

2.Check any gaskets for leakage. Tighten or replace, if needed. Do not overtighten bolts - gasket damage can occur.

3.Visually inspect pilot and burner flames. Reference “Check Main Burner Flames”and“Check Pilot Burner Flame,”page 21.

4.Visually inspect venting system for blockage, deterioration or leakage. Reference “Inspect Venting System,”page 21.

5.Check automatic air vent for leakage. If leaking, remove vent cap and push valve core in to wash off sediment that may have accumulated oft the valve seat. Release valve, replace cap and open one turn.

End of each heating season:

1. Follow“Annual Shutdown Procedure,”page 21.
