Top Features

Low gas pressure operation: Negative pressure regulating gas valve ensures maximum performance all the way down to 3.5″ of water column on natural gas and 8″ of water column on propane gas.

Space saving and light weight design: The sleek wall-hung design uses much less space and is substantially lighter than traditional floor standing boilers, making installations a lot easier.

Dual Venturi and field gas convertibility: Dual Venturi system creates better combustion control and turndown ratio. Field gas convertibility is easy with orifice conversion kits for NG high altitude (5,400–10,100 ft.) and LP (up to 10,100 ft.) included with NFC-H Series combi-boilers.

Uses existing 1/2″ gas piping : Save time and cost in retrofit application by reusing existing ½” gas lines for up to 24′ in length. Subject to local code.

Low noise levels: Installations in or near media rooms, recreation rooms or any living areas of the house are possible with the quiet running NFB-H combi-boilers.

Up to 15:1 turndown ratio: The sophisticated gas flow control system provides a high turndown ratio, reducing energy waste and excessive boiler cycling and enhances temperature control for DHW.
