PRODUCT DESIGN
If the combustion air intake pipe is to be installed above a
finished ceiling or other area where dripping of condensate
will be objectionable, insulation of the combustion air pipe
may be required. Use 1/2" thick closed cell foam insulation
such as Armaflex or Insultube where required.

1) Minimum requirement for each vent pipe is five (5) feet in length and
one elbow/tee.
2) Tees and/or elbows used in the vent/flue termination must be in-
cluded when determining the number of elbows in the piping sys-
tem.
3) 3" diameter pipe can be used in place of 2" diameter pipe.
4) Increased Clearance Configurations using (2) 45 deg. Long Sweep
elbows should be considered equivalent to one 90 deg. elbow.
