Our tubular, indirect gas-fired furnaces provide flexibility and the latest heat exchanger technology. The heating module has a slide-in design for easy installation, higher efficiency, and lower static pressure. The variable burner controller provides timing, sequencing, and safety control of the system. The main board directly controls the main gas valve, modulating gas valve, ignition source, and variable inducer to provide modulating heating for the application while maintaining the proper air/gas ratio throughout the modulation range.
