A
CAUTION: This venting system requires the
installation of a condensate drain in the vent piping per
the vent manufacturer’s instructions. Failure to install a
condensate drain in the venting system will cause non-
warrantable damage. Condensate is acidic and highly
corrosive.
NOTE: Ensure adequate clearances to allow annual
inspection of the venting system.
