The low-NOx line of KC1000 commercial and industrial high-efficiency boilers and water heaters has been enhanced. The 1 million-Btuh condensing units, which maintain an environmentally friendly profile, now support sealed combustion and can be configured to support dual fuel (natural gas or propane) applications. Any new low-NOx KC1000 unit can be installed with sealed combustion in all climates. They will not require seasonal combustion air recalibration in those applications where ambient air temperatures remain between -30° and 130°F. These boilers and water heaters will be shipped with a replacement spring for the unit’s differential regulator that also supports a switch from natural gas- to propane-fired operation (or vice versa). Their condensing design eliminates secondary piping and their 11:1 turndown supports tight temperature control and a greater range of noncycling operations. Each unit can be used in single unit or in modular arrangements for inherent standby with minimum space requirements. Both boilers and water heaters incorporate easy-to-use, advanced control software that integrates with BAS/EMS systems and can be accessed remotely.
