QVM 9
Series 18
■ Due to the extremely low flue temperatures, the QVM 9 series water heater may be vented using 3"
schedule-40 venting materials.
■ Cut all lengths of pipe cleanly maintaining a 90-degree square edge. Use long radius elbows whenever
possible.
■ Use only the type of adhesive recommended by the PVC pipe manufacturer.
■ Keep an uphill slant from water heater to the outside to ensure that all condensed water inside the pipe will
return back to the water heater.
■ Do not place the outdoor termination kit in an area where discharge gases will be directed towards
evergreen shrubbery.
■ Assemble the flue using the following illustration as a guide. Your installation may vary slightly from the
illustration shown below.
Installation of the Flue
Use the supplied SCF-2 Termination Kit for venting the QVM 9 water heater to the outside.
- Optional : The Stainless Steel SCF-9 Coaxial Vent Kit may be used in place of the SCF-2 PVC
Termination Kit.
