G32 VENTING IN EXISTING CHIMNEY
NOTE−Do not discharge exhaust gases directly into any chimney or vent stack. If verti
cal 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. An alter
nate method is to fill the chimney with vermiculite or equal to take advantage of its
acoustic and thermal properties.
