Thermal Solutions TSBC Controlled Gas Fired Hot Water Boiler

Thermal Solutions gas fired hot water boiler with the manufacturer's TSBC microprocessor boiler control. The unit is a floor-standing, cabinet-enclosed hot water boiler intended for building and process hot water heating service, with a packaged power burner, blower and combustion air/flue connections on the rear of the jacket and threaded supply and return water connections at the top of the heat exchanger section. The front control panel carries the Thermal Solutions TSBC keypad with POWER and ALARM indicators, an alphanumeric display and MENU / UP / DOWN / ENTER keys for setpoint and diagnostic entry, plus a combustion air filter ON / CHANGE FILTER indicator panel at the upper right. The upper compartment houses the burner, blower assembly, combustion chamber access cover and the control wiring enclosure with an AC Tech drive module visible behind the access door. Boiler safety controls include a McDonnell & Miller GuardDog model 750-MT-120 probe-type low water cut-off with manual reset, labeled for CSD-1 compliance. A State of Arizona Boiler Safety inspection tag is attached next to the control panel, jurisdiction number AZ818883, dated 08/11/2021, status Active, listing a maximum temperature of 250 degrees F; the MAWP field on the tag is not filled in. A handwritten note on the combustion chamber cover reads "NEW 11-4-2020". Overall footprint as recorded for this listing is approximately 32 in long by 30 in wide by 72 in high. The boiler has been removed from service and is presently stretch-wrapped and sitting on warehouse decking, as shown in the photos. The specific model/size designation was not captured in the photographs, and the unit has not been tested or powered up for this listing. Buyers should verify the rating plate data and model number at inspection.
