MasterTemp service should examine airflow, ignition, combustion, heat transfer, water flow, pressure proving, sensors, wiring, and the complete startup sequence.
Technical guidance
Blower performance, intake and exhaust paths, pressure proving, venting, and equipment clearances affect ignition and safe operation.
Igniter condition, gas valve command, flame signal, wiring, grounds, and control response should be tested in sequence.
Restricted heat transfer, corrosion, scaling, burner condition, or combustion problems may lead to overheating and shutdowns.
Pump condition, filter pressure, valves, internal bypass components, pressure switches, and temperature rise all affect performance.
Stored or recurring faults should be compared with live operation before parts are recommended.
