Final Installation Check:
Check that horizontal vent pipe runs slope uniformly at
least 1/4" per foot to condensate drain(s). No sags, no dips,
no high or low spots.
Check that vent is supported at elbows, tees, and horizon-
tal and vertical runs according to manufacturer's instruc-
tions and code requirements.
Check that vent supports and wall and ceiling penetrations
allow free movements up, down, and sideways without
putting any strains on the heater or vent body.
Check for at least six (6) inch free air clearance between
the heater vent pipe and combustible materials.
Check that all joints are completely together and sealed.
