THE CORPORATE TWIN-ENGINE AIRPLANE WAS TAXIING FOR DEPARTURE WHEN THE PILOT TURNED THE COCKPIT/CABIN HEATER ON. APPROXIMATELY FIVE MINUTES LATER AN EXPLOSION OCCURRED WHICH CAUSED TWO OF THE THREE BAGGAGE DOORS TO COMPLETELY SEPARATE FROM THE AIRFRAME. A THIRD DOOR REMAINED ATTACHED WITH BY A HINGE. DURING THE ON-SCENE INVESTIGATION EXPLOSION/FLAME DAMAGE TO THE BAGGAGE COMPARTMENT INTERIOR AND THE INTERIOR SIDES OF THE DOORS WAS NOT OBSERVED. INSPECTION OF THE HEATER UNIT REVEALED THE COMBUSTION AIR PRESSURE SWITCH WOULD NOT INTERRUPT ELECTRICAL POWER TO THE FUEL SOLENOID VALVE WHEN AIR PRESSURE WAS REMOVED FROM IT. THE SOLENOID ALLOWED FUEL TO ENTER THE HEATER UNTIL CONDITIONS ALLOWED THE EXPLOSION.
