Introduction to the Bradford White U175S-RN Gas Water Heater

The Bradford White Eco-Magnum Series Gas Water Heater U175S-RN is an atmospheric, ultra-low-NOx residential water heater designed to provide dependable domestic hot water for homes and similar applications. Its gas-fired storage-tank design heats and stores water so hot water is available when household fixtures require it.

This Bradford White gas water heater is intended for installation by a qualified professional familiar with fuel-gas piping, combustion air, venting, plumbing, and local building codes. It may suit households replacing a conventional atmospheric gas water heater or installing a new storage water-heating system where compatible venting and gas service are available.

The Eco-Magnum design combines a glass-lined tank with combustion and control components intended for reliable operation. Ultra-low-NOx combustion helps the appliance meet applicable emissions requirements, while the atmospheric configuration uses natural draft through an approved vent system. The unit is not a tankless heater, heat-pump water heater, or electronically connected smart appliance.

Before installation or service, read the manufacturer’s installation and service documentation, verify the rating plate, and confirm that the model, fuel type, vent arrangement, and replacement parts match the appliance. Never bypass safety controls or attempt gas-component repairs without proper training.

Install the vent connector with the required slope, support, materials, and clearances. Verify that the vent terminates safely and drafts correctly.
Fill the tank completely by opening a hot-water faucet until air is purged and water flows steadily. Never fire an empty tank.
Check every water and gas connection for leakage using approved methods. Never use an open flame to test for gas leaks.
Follow the lighting instructions on the appliance label. If gas odor is present, do not operate switches, create sparks, or attempt ignition; leave the area and contact the gas supplier or emergency service.
Set the water temperature to a safe level appropriate for the household. Use mixing or anti-scald protection where needed, especially around children, older adults, or people with limited mobility.

The U175S-RN is not configured for wireless pairing or app connectivity. If the burner does not light, check the gas shutoff position and follow the lighting label, then arrange professional service if the problem continues.

U175S-RN Troubleshooting Guide

No hot water

Confirm that the gas supply is available, the appliance control is set correctly, and the pilot or ignition sequence follows the lighting instructions. If the burner repeatedly fails, stop resetting the control and contact a qualified service provider.

Insufficient or inconsistent hot water

Check for excessive demand, a leaking hot-water faucet, a malfunctioning mixing valve, or incorrect plumbing connections. Sediment buildup, a deteriorated dip tube, restricted gas supply, or venting problems may also reduce recovery and require professional diagnosis.

Water is too hot

Reduce the temperature setting according to the appliance instructions and verify the temperature at a fixture with a suitable thermometer. A failed control, thermostat, or mixing valve requires qualified service.

Water leakage

Identify whether water is coming from a pipe connection, relief valve, drain valve, or tank. Shut off the water supply if leakage is significant. A leaking tank generally requires replacement rather than field repair.

Pilot outage, unusual noise, or soot

Do not operate a heater showing soot, combustion damage, repeated pilot outage, or unusual combustion noise. Turn the appliance off and have a qualified technician inspect gas pressure, combustion air, burner condition, and vent draft.

The manufacturer’s service manual identifies this model family as requiring qualified service providers; model-specific diagnostic procedures and status indications should be followed rather than guessed.
