SECTION 4.

Maintenance

1.At start-up and every six (6) months thereafter, the pilot and main burner flame should be observed for proper performance (see Figures 9 and 10; see attached lighting and shutdown instructions for proper pilot flame pattern). If flame has the appearance of “sooting” tips, check for debris near orifices. Call service technician.

Figure 10. Periodic Flame Observation.

2.Inspect the venting system for obstruction, leakage, and corrosion at least once a year.

3.Keep boiler area clear and free from combustible material, gasoline and other flammable liquids and vapors. Boiler surfaces are hot and could ignite combustible materials.

4.Be certain all combustion air and ventilation openings are unobstructed.

5.Check for fouling on the external surfaces of the heat exchanger every six months.

NOTE: After installation and first start-up, check the heat exchanger for fouling after the following periods of operation: 24 hours, 7 days, 30 days, 90 days, and once every six months thereafter.

Fouling on the external surfaces of the heat

exchanger is caused by incomplete combustion, and is a sign of combustion air and/or venting problems. As soon as any fouling is observed, the cause of the fouling should be corrected (see Section 5 Troubleshooting). The heat exchanger can be checked

with a flashlight by locating a mirror under the burners. An alternate method is to remove the venting and top panel as necessary to inspect from above. Also, check the vent system for defects at the same time.

a.If cleaning is required, shut off all electrical and gas supply to the boiler.

b.To expose the heat exchanger:

Remove top panel covers located at the base of the front and rear flue collector panels. Remove all but the top screws on each side of the front and rear flue collector panels. The panels can be swung outward and propped up to reveal the heat exchanger. Remove all heat exchanger baffles.

c.Remove all burners:

Caution

Black carbon or green soot on a dirty heat exchanger can, under certain conditions, be ignited by a random spark or open flame. To prevent this unlikely occurrence, dampen the soot deposits with a wet brush or fine water spray before servicing or cleaning the heat exchanger.

With a wire brush, remove soot and loose scale from the heat exchanger. Do not use water or compressed air for cleaning. Clean fallen debris from the bottom of the boiler. Check that burner ports are clear and pilot assembly is free of debris.

d.Reassemble in reverse order:

Be sure to replace the heat exchanger baffles.

6.The gas and electric controls installed on the boilers are designed for both dependable operation and long life. But the safety of this equipment depends completely on their proper functioning. It is strongly recommended that the basic items be checked by a competent service technician every year, and replaced when necessary. The basic controls are:

a.Water temperature controls.

b.Pilot safety system.

c.Automatic electric gas valve(s).

d.Water pressure switch.

e.Flow sensing safety device (when used).

7.Low water cutoffs should be inspected every six

(6) months, including flushing or float types.

NOTE: Warranty does not cover any damage caused by lack of required maintenance or improper operating practices.
