Bradford White Water Heater EF60T1993XA2

Service Procedure III — Burner Tube Inspection & Replacement

Turn the main power switch off and unplug the water heater, then turn off the gas supply.

Remove the surround cover, then disconnect the gas connection, PVC venting, wire harness, and silicone tubing from the gas valve.

Disconnect the wire harness from the blower assembly.

Remove the two screws holding the hot surface igniter and flame sensor and carefully remove them (for Direct Spark Ignition models, remove the spark rod bracket screws and spark rod instead).

Remove the four nuts holding the burner transition, lift the blower/gas valve/transition assembly off, and set the gasket aside.

Remove the burner tube from the burner mounting insert.

Service Procedure XIV — Flue Baffle Inspection and Replacement

Warning: Heater components can be hot during this procedure; take precautions to avoid injury.

Disassemble the heater per the Disassembly Procedure for Access to Anodes & Flue Baffles.

Remove the flue baffles with pliers.

Visually inspect the baffles for oxidation and missing restrictors.

Replace any baffle with deteriorated oxidation or missing restrictors.

Reinstall the flue baffles once inspection or replacement is complete.

Reinstall the collector cover per the Collector Cover Installation Procedure.

Service Procedure IX — Spark Rod Gap Inspection and Adjustment (Direct Spark Ignition models)

Remove the combustion system per the Combustion System Removal procedure

Measure the spark gap between the spark rod and burner tube

Is the spark gap within the acceptable range of 3/16 in. to 1/4 in.?

Carefully bend the spark rod if the gap is out of range

Re-measure to confirm the gap is within 3/16 in. to 1/4 in. after bending

Reinstall the combustion system

Check several ignitions to confirm the burner lights smoothly

Service Procedure XIV — Anode Inspection and Replacement

Turn off the water supply and drain the water heater

Disassemble the heater for access to anodes and flue baffles

Locate and remove the anode rods using a 1-1/16 in. hex socket

Visually inspect each anode rod for depletion

Apply thread sealing tape or compound and reinstall the anode rods

Restore the water supply and check for leaks

Service Procedure VIII — Flame Sensor Testing & Replacement

Check for a minimum of 1 microamp during the 1.5-second flame-proving period

Enter the microamp reading during the flame-proving period

Is the flame-sensing circuit okay?

Check for the expected 24VAC at the ignition module/control board flame-establishing terminals

Is the 24VAC present at the ignition module/control board?

Call technical support if 24VAC is absent and describe the issue

With the sensor disconnected, check for continuity to ground
