A vented, fire resistant collar shall be installed around a stovepipe or exhaust vent passing through a wall, ceiling, floor, or roof unless otherwise specified by the manufacturer.
(F) When a heating system has automatic controls, the controls shall be of a type which cut off the fuel supply upon the failure or interruption of the flame or ignition, or whenever a predetermined safe temperature or pressure is exceeded.
