The Heatmaster MF-3000 stove could continue boiling water after being turned off due to the following reasons:

1. Overheating – If the furnace was excessively hot before shutting down, residual heat could continue to boil the water.
2. Improper Venting – If airflow is restricted, trapped heat may not dissipate properly, leading to continued boiling.
3. Malfunctioning Aquastat – If the aquastat fails to detect high temperature correctly, it may not shut off the draft fan in time.
4. Clogged or Blocked Heat Exchanger – A blockage could trap heat inside the system, causing water to overheat.
5. Inaccurate Furnace Sizing – If the furnace is too large for the heat demand, it may generate excess heat, leading to boiling.

Checking the aquastat, airflow, and system sizing can help prevent continued boiling after shutdown.
