Vent teRmination RestRictions:
WARNING: This appliance has been designed to draw room air and discharge heated air
from the openings around the nishing edge. Blocking or modifying these openings in
any way can create hazardous situations. Only Approved Direct Vent may be used for
installation of the C60I.
The minimum vent installation for the C60I must include a 24” vertical section and 90° elbow
before being horizontally vented. Maximum vertical venting is 40’ (12.2 m). This model is
vented with co-axial 5” exhaust, 8” intake aluminum or stainless steel approved rigid vent leading into
a vertical or horizontal termination cap. The ue collar of this model will t inside of a standard 5”x 8”
vent and must be either correctly interlocked or fastened, with three screws directly to the vent collar.
Check periodically that the vents are unrestricted. Also ensure that all direct vent pipes have been
properly sealed and installed after routine inspection or cleaning. The air intake and exhaust pipes must
be installed in the correct locations on the top of the C60I.
