Heating Coil
Coil Descaling:
In hard water areas, scale buildup within
the heating coil will occur. Scale deposits will decrease
the water temperature rise and may eventually clog the
heating coil. Contact your local service center when
descaling is needed.
Coil Desooting:
Poor grades of fuel oil or inadequate
combustion air will cause heavy soot buildup on the
outside surface of the heating coil. This will restrict the
airflow through the coil, further aggravating the soot
buildup. Contact your local service center when desooting
is needed.
