Maintenance

Operation

To insure accuracy for rating, clock enough cubic feet of gas so that the clocked time is at least 60 seconds.

Small adjustments can be made by varying the manifold pressure from the designated settings mentioned above.

5.INTERMITTENT PILOT FLAME ADJUSTMENT — No adjustment is required with normal inlet gas pressures. The pilot flame adjustment valve is pre-set, and does not normally require re-adjustment.

6.HIGH ALTITUDE — Ratings of gas appliances are based on installation and operation at sea level of elevations of 2000 feet.

Factory prepared high altitude models are available and are specifically rated for installation at elevation up to 8000 feet. Refer to rating plate on the front of the water heater for number and altitude specifications. Also refer to the supplement sheet for information on venting high altitude models.

7. EMERGENCY SHUTDOWN —

!WARNING

Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.

!WARNING

DO NOT use this appliance if any part has been under water. Imme- diately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.

If the water heater has been subjected to fire or physical damage, turn off gas at the manual gas control (shut-off) valve. Do not operate the water heater again until it has been checked out by a qualified service technician.

Properly maintained, this water heater will provide years of dependable, trouble free service. It is strongly suggested that a regular routine main- tenance program be established and followed by the owner. It is further recommended that a periodic inspection of the blower, thermostat, burner, relief valve, internal flueway, draft hood / damper assembly and venting system should be made by service technicians qualified in gas appliance repair.

1. ROUTINE PREVENTIVE MAINTENANCE

A.BURNERS — Visually inspect the main burner flame and the pilot flame at least every three months. Refer to Figures 12 and 13 for normal flame pattern. Fallen scale can usually be dislodged from the tops of the burners with a thin rod, then vacuumed or brushed from the bottom of the burner box. If a more thorough cleaning is deemed necessary to restore a normal flame pattern, the burner tray assembly should be removed and the burners cleaned individually.

!CAUTION

For your safety, removal and cleaning of burner tray and individual burners should be performed ONLY by a qualified service techni- cian, as it involves disconnection of gas piping and leak testing.

TO REMOVE BURNER TRAY:

1.Turn off manual gas shut-off valve.

2.Disconnect gas pipe union and wiring to gas valve and pilot.

3.Remove retaining screws from plate on the same side as the gas valve.

4.Slide burner tray assembly out. When reinstalling the burner tray assembly, make certain it is pushed in all the way so that the plate lines up with the holes in the plenum side. Then reinstall the retain- ing screws.

5.Reconnect gas pipe union and wiring to gas valve and pilot, turn on manual gas shut-off valve and test for gas leak.

B.VENTING SYSTEM — Inspect venting system at least yearly to make certain the passageways are free and unobstructed, and that the vent connector from the water heater’s blower assembly is properly posi- tioned and securely attached. Remove any obstructions in vent con- nector or vent terminal.

C.CONTROLS — The manifold pressure and controls should be checked at least yearly by a qualified service technician.
