To Next PageTo Next PageWhy is the THERMO 2000 BTH ULTRA 12 Boiler safety valve leaking?
The boiler safety valve might be leaking because the pressure reading is above 28psi, indicating a defective pressure regulator or an issue with the expansion tank (too small or defective). Alternatively, if the pressure is below 28psi, the safety valve itself may need replacement.
What to do if the THERMO 2000 Boiler releases an overheated plastic odor?
If you notice an overheated plastic odor coming from your THERMO 2000 Boiler, immediately turn the power OFF. Then, open the front and left side panels to inspect the components and electric wires for any signs of overheating. Replace any overheated components and verify the supply voltage to the boiler.
