DIRECT VENT APPLICATION

NOTE
− Do not discharge exhaust gases directly into any chimney or vent st ack. 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.
