Top 8 How To Adjust The Gas Pressure On An Ao Smith Tankless Water Heater

Professional classic® tankless electric water heaters offer continuous hot water quick and on demand for single point-of-use or multiple applications

The WH-HD200-C Heavy Duty clear whole house system with clear sump allows you to see your filter in action. Included with the unit is a mounting bracket, housing wrench, filter life indicator, built in shut-off, bypass, and pressure relief valve.

Amtrol ST-12 THERM-X-TROL Expansion Tank, 4.4 Gallon (141N43) What Is Thermal Expansion? With modern plumbing codes mandating backflow prevention, thermal expansion can cause pressure buildup in domestic water systems. When demand is put upon a potable water system, hot water is drawn from the water heater. Cold water from the supply line enters the water heater to replenish it. The colder water is heated to replace the hot water used. With the installation of a backflow preventer, check valve or pressure reducing valve on the supply line, the water heater and the system piping form a closed plumbing system under pressure. As the water is heated, thermal expansion occurs. Pressure increases until the relief valve opens and the expanded water “spills” from the water heater. This “spillage” results in wasted BTU’s and a potential safety hazard for the homeowner. Closed Potable Hot Water system without THERM-X-TROL Backflow preventer, pressure reducing valve or meter causes expanded (heated) water to build pressure causing the relief valve to open resulting in: Wasted BTU’s Shortened water heater life Wasted municipal water and sewer dollars Potential safety hazard for homeowner The Amtrol THERM-X-TROL ST-12 Expansion Tank is designed to eliminate this problem by providing control of maximum pressures at a level below the relief valve setting. It also provides an additional space in the system to accommodate the increased volume of water created by thermal expansion, returning it to the system when hot water delivery is demanded.

Genuine Original Equipment Manufacturer (OEM) parts! This gas valve and temperature control assembly (part number 6911131) is for water heaters. Gas valve and temperature control assembly 6911131 supplies the burner with fuel to heat the water. The temperature control thermostat controls the gas valve. A service technician is recommended for this repair because the gas supply line connections must be checked for leaks after the repair. For American Water Heaters.
