375-D Hydronic Heating System Installation Manual Rev. A
NOTE:
Please note that a return-air register may not be re-
quired; however, adequate return-air must be provided
to each particular heat exchanger. This means that the
total cross-sectional area of the return-air opening must
be equal to or greater than the cross-sectional area of
the hot-air outlet opening of the heat exchanger.
