5. If positive forced ventilation is adopted, ensure that
there will be no appreciable pressure variation in the
equipment room.
6. Avoid ventilation which creates a negative pressure
in the building as it will seriously aff ect combustion
and proper operation of the stack. Please note that
exhaust fans or similar equipment can create a down
draft in the chimney or starve the burner’s air supply.
Either case may result in poor combustion or nuisance
failures. A properly designed make-up air system in the
equipment room will preclude these possibilities and is
required to maintain proper combustion.
