TK-540X3-NIH - 199,000 BTU Natural Gas Indoor Condensing Ultra-Low NOx w/X3™ Technology

The 9008847005 Non-Return Valve is a must-have item for common venting system. It prevents the escape of combustion gas through non-operating appliances.

For Use with the following models:

T-H3J-IN, T-H3S-IN, T-H3-IN

The 9007611005 Concentric PVC Termination is used when terminating direct-vent (sealed combustion) systems, with Indoor models that require a 3 in. (76 mm) intake and a 3 in. (76 mm) exhaust. This concentric termination provides the convenience of only having to make one penetration through a sidewall instead of two separate penetrations for the intake and exhaust piping. The termination includes a bird screen, restricting small animals, pests, and foreign objects from entering into the vent system.

For Use with the following models:

T-H3M-IN, T-H3J-IN, T-H3S-IN, T-H3-IN 

The 9008331005 Pipe Cover protects the plumbing pipes to the water heater from unexpected adjustments. This pipe cover is fixed to the bottom of the water heater, which hides the plumbing and improves the visual aspects of the whole installation for the water heater.

For Use with the following models:

T-H3J-IN, T-H3J-OS, T-H3S-IN, T-H3S-OS, T-H3-IN, T-H3-OS

The 9008300005 Multi System Controller is capable of handling up to 20 units at one time. It also works as a diagnostic tool that provides error codes.

For Use with the following models:

T-D2U-IN, T-D2U-OS, T-H3-IN, T-H3-OS, TK-510C

The 9008172005 Temperature Remote Controller (TM-RE40) is designed for commercial tankless applications that require higher outlet temperatures. It also works as a diagnostic tool that will give a concise error code whenever there is a problem with the unit.

For Use with the following models:

T-H3-IN, T-H3-OS

The 9007604005 Lead Free Isolation Valves & Pressure Relief Valves are used to isolate a unit for service. The Pressure Relief Valve is to help protect the unit and release if the pressure in the tankless water heater or hot water system exceeds 150 psi and up to 200,000 BTUs. For 3/4" water lines. (1953 Compliant)

For Use with the following models:

TK-110C-NI, TK-310C-NI, TK-510C-NI, T-KJr2/U, T-K4/U, T-D2/U, T-H3M, T-H3J, T-H3S, T-H3

The 9007607005 Neutralizer assembly neutralizes the condensate (acidic water) that forms in the secondary heat exchanger of the water heater. It connects to the condensate drain port of the water heater by using connectors included with the neutralizer kit.

For Use with the following models:

T-H3M-IN, T-H3M-OS, T-H3J-IN, T-H3J-OS, T-H3S-IN, T-H3S-OS, T-H3-IN, T-H3-OS

Did you know more than 85% of American homes have hard water and that hard water scale is a leading cause of failure for tankless water heaters?

The Product Preservers® Anti-Scale System protects your tankless water heater from damage due to scale formation. This system does not add chemicals to the water or require electricity. As water flows through the filter, hard water minerals form inactive scale crystals which flow through the water heater without sticking to the heat exchanger.

The system virtually maintenance free as the filter only needs to be changed every two years. Replacing the filter is easier, faster, and needs to be less frequently than using isolation valves to flush a water heater with a cleaning solution to remove scale buildup.
