Bradford White Water Heater EF100T199E3NA2

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

Replace baffle if deteriorated oxidation or missing restrictors are found

Service Procedure III — Burner Tube Inspection & Replacement

WARNING — Heater components can be hot during this procedure; take precautions to avoid injury.

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 — 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

Reinstall the collector insulation and control panel

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.?

If out of range, carefully bend the spark rod

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 XII — Intake Pressure Testing (models prior to serial "CF" only)

Check continuity through the normally closed intake pressure switch if the blower does not energize

Refer to the vent safety switch, exhaust pressure switch, or blower testing procedures if the intake pressure switch is not faulty

Check continuity through the switch if the purge LED does not illuminate within the expected time

Confirm the inlet tube pressure tap reads at least -1.2 in. W.C. using a manometer

Remove the hose from the intake pressure switch and restart the heater to see if the purge LED illuminates

Isolate the heater from the intake vent system and restart again to isolate a switch versus vent-system fault if the purge LED illuminates

Check whether the intake vent system is obstructed and clear any obstruction found

Call technical support if no cause is found
