Normal Inspection Procedures

First and third month after initial start up and then on an annual basis. If problems are found, refer to Trouble Shooting Guide for additional directions.

1.Remove top of heater and inspect heat exchanger for soot and examine venting system.

2.Remove rear header and inspect for scale deposits.

*3. Inspect pilot and main burner flame and firing rate.

*4. Inspect and operate all controls and gas valve.

*5. Visually inspect system for water leaks.

*6. a. Oil pump motor and bearing assembly, if oil cups are provided.

b.Disconnect pump from header and check con- dition of pump impeller. Check condition of bearing by attempting to move impeller from side to side. Replace any parts showing wear.

c.Check pump coupler for wear and vibration.

7.Check flow switch paddle (if provided).

8.Clean room air intake openings to assure ade- quate flow of combustion and ventilation air.

9.Keep heater area clear and free from combustible materials, gasoline, and other flammable vapors and liquids.

*Should be checked monthly. (Takes approximately 15 minutes).

Procedure for Cleaning Flue Gas Passage Ways

Soot will clog areas behind fins and eventually cause tube failure. Any sign of soot at base of burners or around outer jacket indicates a need for cleaning.

1.Lift off draft hood and flue collector by removing bolts and screws.

2.Remove "V" baffles from heat exchanger.

3.Remove burner tray, see Burner Drawer Removal.

4.Take garden hose and wash heat exchanger, mak- ing sure soot is removed from between fins. (Avoid excessive water against refractory).

5.Reassemble; when heater is fired, some steam will form from wet refractory, which is normal.

NOTE: In extreme cases it may be necessary to remove the heat exchanger completely for cleaning. The simplest method is steam cleaning at a local car wash.

CAUTION: Soot is combustible. Exercise extreme care. Do not wire brush.

Burner Drawer Removal

1.Shut off power and gas supply to the heater. Disconnect union(s) and pilot tubing when present; then loosen and remove burner hold down screws.

2.Disconnect wires at gas valve and slide burner drawer out.

Main Burner and Orifice Removal

1. Remove screws and burner hold down bracket.

NOTE: If the heat exchanger is sooted badly, the burner hold down bracket and spacer can become distorted from direct flame impingement and this usually necessitates replacement of these parts.

2.Lift burners from slotted spacer and slide from ori- fices. Clean with a wire brush.

3.Orifices usually do not need to be replaced. To clean, run either copper wire or wood through ori- fice. Do not enlarge hole. To remove orifice, use a socket wrench and remove the manifold. DO NOT overtighten when reinstalling.
