SECTION V: VENTING The water heater models described above in this supplement are of the induced draft type which rely on an induced draft blower to pull the combustion products through the flue tubes of the water heater. An integral gravity damper on the induced draft blower outlet is forced open by the air pressure from the blower and closes at the end of each burner cycle. NO ADDITIONAL VENT DAMPERS ARE TO BE ATTACHED TO THE OUTLET OF THESE APPLIANCES.

SECTION VIII: ELECTRICAL CONNECTIONS This water heater must be wired to a 120volt, 60Hz or 240 volt, 50/60 Hz. power supply. Refer to the wiring diagram on the water heater for proper field wiring connections. Refer to the water heater rating plate for the correct voltage. Refer to the nameplate for the total amp draw for this water heater. The water heater must be wired on a separate circuit and breaker.

SECTION X: MAINTENANCE The following maintenance should be performed by a qualified service technician at the minimum periodic interval listed below. 1. Bi-annually, oil the induced draft motor in the ports of the front and rear motor bearings with 4 drops each of SAE 20 motor oil. 2. Annually, inspect the blower wheel for debris and clean as necessary. 3. Inspect the venting system for corrosion and leaks. Replace any defective sections of vent pipe. 4.

SECTION XI: DIAGNOSTIC AND TROUBLESHOOTING GUIDE DIAGNOSTIC GUIDE FOR HONEYWELL INTEGRATED CONTROL SYSTEM SEQUENCE OF OPERATION FOR INDUCED DRAFT MODELS 1. When the tank temperature drops below the temperature setpoint on the display, the control sends power to the induced draft blower to start the ignition sequence. 2. When the blower reaches the full operating speed, the pressure switch closes, completing the 24 volt circuit to the safety circuit of the control.
