2.7. AIR VENTING OF THE HEATING SYSTEM
The AM Series units come standard with automatic air vents on each of the headers on the rear of the
unit (see Figure 6a and 6b). These vents are for the unit only and not the entire heating system. An
effective air vent for air removal for the entire heating system must be installed in the highest point of
the system piping.
