NOTE − Do not discharge exhaust gases directly into any chimney or vent stack. If ver- tical discharge through an existing unused chimney or stack is required, insert piping inside chimney until the pipe open end is above top of chimney and terminate as illus- trated. In any exterior portion of chimney, the exhaust vent must be insulated.
