MAINTENANCE

WARNING

Do not store or allow combustible or flammable materials near the boiler. Substantial fire or explosion hazard could result, causing risk of personal injury, death or property damage.

Do not use this boiler if any part of it has been under water. Immediately call a qualified service technician to inspect the boiler. Any part of the control system, any gas control or any burner or gas component which has been under water must be replaced.

Should overheating occur or the fuel supply fail to shut off: Shut off the fuel supply at a location external to the boiler. Do not turn off or disconnect the electrical supply to the pump. Immediately call a qualified service technician to inspect the boiler for damage and defective components.

A.PLACING BOILER IN OPERATION

1.Start up the Burner/Boiler per the Burner Manual and the instructions in this manual on starting the boiler.

2.Prove the correct operation of all controls on the boiler and burner as outlined below.

3.Check the operation of the ignition and flame proving controls as described in the Burner Manual.

4.Test the limit and operating controls to assure they are operating correctly.

5.Inspect and test all low water cutoffs.

6.Test the safety relief valve(s) using the procedure given by the valve manufacturer on the valve tag.

7.Visually inspect the burner and pilot flames (if applicable).

B.TO SHUT DOWN THE BOILER

1.Turn off Burner.

2.Open main line power disconnect switch to boiler/burner.

3.Close fuel shut-off valves.

4.To take boiler out of service if the boiler and system are not to be used when temperatures are below freezing:

a)Drain the boiler and system completely and shut off make-up water supply.

b)Open main line power disconnect switch to boiler/burner. Remove the fuses or secure the switch so that the power cannot be turned on accidentally.

c)Be certain that the boiler and system are refilled before returning to service. Follow the Instructions in this manual and the Lighting Instructions to operate.

d)The system may be filled with a 50% inhibited propylene glycol solution for protection down to -35°F. Use only antifreeze solutions specifically designed for hydronic use.

C.MAINTENANCE – ANNUAL

1.Before the start of each heating season, inspect and make all necessary adjustments to insure proper boiler and burner operation. Use the maintenance and inspection procedures following.

2.Inspect the Venting System

a)Check the chimney or vent to make sure it is clean and free from cracks or potential leaks.

CAUTION

Before servicing the boiler:

Turn off all electrical power to the boiler.

Close the Gas Service Valve and Oil Shut-Off Valve.

Allow the boiler to cool if it has been operating.

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

b)All joints must be tight and sealed.

c)The vent connector must extend into, but not beyond the inside edge of the chimney or vent.

3.Inspect the Boiler Area

a)The boiler area must be clean and free from combustible materials, gasoline or any other flammable liquids or vapors.

b)The combustion air openings and the area around the boiler must be unobstructed.

4.Inspect boiler flueways and burner for cleanliness. If cleaning is required, use the following procedure.

a)Turn off all electrical power to the boiler.

b)Remove Jacket Middle Front Panel and Jacket Top Panels. Remove Front Cleanout Plate and Cleanout Cover Plates on each flueway. On LCE boilers, remove the top flue outlet plate and vent piping as necessary to access the top of the sections.

c)Brush the boiler tube spaces both horizontally (through cleanout openings on ends) and vertically (from top of boiler through cleanout openings at flueways).
