■
Due to the extremely low flue temperatures, the QVM 9 Series boiler 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 boiler to the outside to ensure that all condensed water inside the pipe will
return back to the boiler.
■
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
