providing simultaneous readouts for system pressure and water temperature

preventing overheating or soot accumulation in the heat exchanger

The limited output on the CTE-5104 is used to set adjustable minimum and maximum flow limits for a CSP-5001/5002 controller

a full replacement of the draft inducer wheel is necessary to prevent premature motor failure

it monitors the high-limit switch and thermal well resistance to prevent overheating and ensure safe combustion cycles

Maxitrol M520B-3/4 Gas Valve 328140-751 providing simultaneous readouts for systemThe Maxitrol M520B 3 4 is a specialized 3 4" NPT Modulating Gas Valve engineered for technical precision in negative pressure (pull through) and indirect fired atmospheric burner applications. As a core component of the Selectra electronic gas flame modulating system, this valve provides instantaneous, non fluctuating temperature control without the need for mechanical butterfly valves or motors. Built with a corrosion resistant brass valve body and a
