Remedy

Turn off all hot water taps. Press ON/OFF twice.

Ensure Bradford White approved venting materials are being used. Check that nothing is blocking the flue inlet or exhaust.

Check all vent components for proper connections. Ensure vent length is within limits.

Ensure condensation collar was installed correctly. Verify dip switches are set properly.

Check fan for blockage.

Burner Sensor Error (see code 31) Check the fins in the heat exchanger.

Check that the gas is turned on at the water heater, gas meter, or cylinder. Ensure gas type and pressure is correct.

Ensure gas line, meter, and/or regulator is sized properly. Bleed all air from gas lines.

Verify dip switches are set properly. Ensure water heater is properly grounded.

Disconnect Manifold Electronic Controls to isolate the problem. Ensure igniter is operational.

Check igniter wiring harness for damage.

Check gas solenoid valves for open or short circuits.

Remove burner cover and ensure all burners are properly seated.

Remove burner plate and inspect burner surface for condensation or debris.

Check that the gas is turned on at the water heater and gas meter. Check for obstructions in the flue outlet.

Ensure gas line, meter, and/or regulator is sized properly. Ensure gas type and pressure is correct.

Bleed all air from gas lines.

Ensure proper Bradford White venting material was installed. Ensure condensation collar was installed properly.

Ensure vent length is within limits. Verify dip switches are set properly. Ensure water heater is properly grounded. Disconnect keypad.

Disconnect Manifold Electronic Controls to isolate the problem. Check power supply for loose connections.

Check power supply for proper voltage and voltage drops. Ensure flame rod wire is connected.

Check flame rod for carbon build-up.

Disconnect and reconnect all wiring harnesses on unit and PC board. Check for DC shorts at components.

Check gas solenoid valves for open or short circuits.

Remove burner plate and inspect burner surface for condensation or debris. Check the ground wire for the PC board.

Check gas type of unit and ensure it matches gas type being used. Check for restrictions in air flow around unit and vent terminal.

Check for low water flow in a circulating system causing short-cycling. Ensure dip switches are set to the proper position.

Check for foreign materials in combustion chamber and/or exhaust piping. Check heat exchanger for cracks and/or separations.

Check heat exchanger surface for hot spots which indicate blockage due to scale build- up. Refer to instructions in manual for flushing heat exchanger.

Measure resistance of safety circuit.

Ensure high fire and low fire manifold pressure is correct. Check for improper conversion of product.

Both models feature a powerful, energy-efficient design that significantly reduces energy consumption while providing a consistent supply of hot water.

One of the main features of these models is their use of advanced technology in water heating. The units are equipped with a high-efficiency burner and an optimized heat exchanger that maximizes the transfer of energy, ensuring rapid heating and minimal standby loss. This efficiency is further enhanced by their ability to modulate gas flow, allowing the heater to adjust its operation based on actual demand, rather than running at full capacity at all times.

Safety is a priority in the design of the TGHE-199E-N(X) and TGHE-160E-N(X). Both models are equipped with an electronic ignition system, which eliminates the need for a continuous pilot light, reducing gas consumption and enhancing safety. Furthermore, they include advanced venting options, such as concentric or PVC venting, providing installation flexibility while adhering to stringent building codes.

Moreover, these water heaters are built to last, featuring a durable tank design with a powder-coated, steel construction and a patented Vitraglas® lining. This lining protects against corrosion and extends the life of the tank, ensuring long-term performance and reliability.

Installation and maintenance of the TGHE-199E-N(X) and TGHE-160E-N(X) are straightforward, thanks to their user-friendly design. They come with easily accessible components, making service and repairs less time-consuming and more cost-effective.
