TUBE CLEANING PROCEDURE

Establish a regular inspection schedule, frequency depending on local water condition and severity of service. Do not let the tubes clog up solidly. Clean out deposits over 1/16" in thickness.

The heater may be cleaned from the return header side, without breaking pipe connections. It is prefer- able, however, to remove both headers for better visibil- ity through the tubes and to be sure the ground-up lime dust does not get into the system.

Note that you do not remove the top panel or the heater exchanger, generally.

After reaming, mount the wire brush in place of the auger and clean out debris remaining in the tubes.

Another method is to remove the heat exchanger, ream tubes and immerse heat exchanger in non-inhib- ited de-scale solvent for severe scale build-up.

DESOOTING PROCEDURE

CAUTION: SOOT IS COMBUSTIBLE. EXERCISE EXTREME CARE:

Soot will clog areas between fins and cause even- tual tube failure. Any sign of soot at the base of the burners or around the outer jacket indicates a need for cleaning.

1.Remove top and flue collector from cabinet.

2.Remove "V" baffles from heat exchanger.

3.Remove burner drawer. (See burner tray removal).

4.Remove heat exchanger from the heater and wash with a garden hose, making sure soot is removed from spaces between fins.

5.Reverse above procedure to re-install.

NOTE: In extreme cases it may be necessary to do steam cleaning at the local car wash. DO NOT

WIREBRUSH.

COMBUSTION CHAMBER REMOVAL

To remove combustion chamber, you must first have removed the heat exchanger. Unbolt metal com- bustion chamber retainer from top and remove combus- tion chamber panels individually.

CONTROL IMMERSION WELL REPLACEMENT (Millivolt and ASME)

1.Shut water off to heater and drain heat exchanger.

2.Remove access panel on water connection side of heater.

3.Remove old control well with bushing and sleeve.

4.Install in header.

NOTE: Installation in plastic should be hand tight plus 1/2 turn.

UNITHERM GOVERNOR (U.G.) REPLACEMENT

1.Shut water, gas and electricity off, close valves and relieve pressure.

2.Drain heat exchanger.

3.Remove retainer plug located next to the outlet pipe connection.

4.Remove old U.G. from retainer plug. It is snapped in place. Snap in new U.G.

5.Reinstall retainer plug, taking care to lubricate gas- ket with a non-petroleum based grease such as AquaLube.
