The Pinnacle® gas-fired boiler is available for either natural or LP gas and is offered in five sizes, including two new models - wall-mount and floor-standing units. Supply and return temperatures, flame signal, and fan speed (firing rate) can be viewed from the LED digital display module for enhanced boiler serviceability, the company says. A switch to the "service mode" enables contractors to control the firing rate manually. PC software is available for displaying boiler status and fault history. All Pinnacle boilers are direct vent, sealed combustion units. An optional interface module allows for external control of outdoor reset, multiple temperature set points, and modulating sequencing of multiple boilers.
