• The first vertical run from the top of the heater
should be no longer than 0.9mm (3').
• Make sure vent pipe is gas tight and will not
leak. Use silicon sealant wherever necessary.
• Do not common vent or connect more than
one appliance to this venting system.
• The total vent length including horizontal & vertical
vent runs should be no less than 0.9mm (3').
• Do not place any dangerous objects at the end
of the exhaust vent.
• Steam (smoke) or water drops may come out
from the end of the exhaust pipe. Select the
location for the end of the vent so that steam is
not visible, and the vent is not wet with drip-
ping water.
• If snow is expected to accumulate, take care
the end of the pipe is not covered with snow or
hit by falling lumps of snow.
• Consult the vent pipe manufacturer's install-
ation instructions for chimney connections.
