OPERATIONS & MAINTENANCE

B.TO SHUT DOWN THE BOILER

1.Open main line power disconnect switch to boiler.

2.Close Main and Pilot gas shut-off valves.

3.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. Remove the fuses or secure the switch so that the power cannot be turned on accidentally.

c.Do not use ethylene glycol antifreeze in a steam boiler or system.

d.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.

CAUTION

Before servicing the boiler:

•Turn off all electrical power to the boiler.

•Close the Gas Service 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.

c.Remove side cleanout panels.

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

e.Replace the flue collector, draft hood, jacket and cleanout panels using the procedures given in this manual.

f.Remove the burners and brush the gas ports lightly with a soft bristle brush.

5.Inspect the boiler base and insulation.

6.Inspect the boiler and piping for signs of leaks. Check to see if there are signs of heavy make-up water addition to the system.

7.When placing boiler into operation, follow Lighting Instructions shipped with the boiler and the instructions in this Chapter.

8.Test the operation of all limit controls, float controls, and ignition components as described in Part A, Placing Boiler in Operation, of this Chapter.

D.MONTHLY MAINTENANCE

1.Inspect the burner and pilot flames as for the annual inspection.

2.Inspect the boiler and system for any signs of leakage or excessive make-up water usage.

3.Inspect and check the operation of the venting system.

C.ANNUAL MAINTENANCE

1.Before the start of each heating season, inspect and make all necessary adjustments to insure proper boiler 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.

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 burners for cleanliness. If cleaning is required, use the following procedure.

a.Turn off all electrical power to the boiler.

b.Remove top jacket panels, draft hood and flue collector.

E.WEEKLY MAINTENANCE

1.Blow down the float type low water cut-offs and test for correct operation.

F.DAILY MAINTENANCE

1.Inspect the boiler area to make sure the area is free from combustible or flammable materials and that there are no obstructions to the flow of air to the boiler or combustion air openings to the room.

2.Make sure there are no signs of abnormal operation, such as overfilling or leakage.

CAUTION

Be very careful when adding water to a hot boiler. Add very slowly or, if possible, allow the boiler to cool naturally before adding water.

If an excessive loss of water occurs, check for a leak in the piping and correct the problem. Excessive make-up water will cause corrosion and damage to the boiler.
