HEAT EXCHANGER COIL MAINTENANCE
Hard water conditions may eventually cause clogging in the heat exchanger coil if left unattended.
n
Scale deposits will compromise the heating efficiency and produce an unsafe condition over time.
It may be necessary to descale coil.
Scale buildup from certain detergents may eventually clog up the heat exchanger coil causing an
n
unsafe condition. Use only recommended detergents for better cleaning efficiency.
Black carbon deposits that collect on the outside wall of the heat exchanger coil may be a result of
n
using a poor grade of fuel or improper burner operation. Heating fuel should be void of water and
sediments to eliminate the possibility of sooting and compromising the efficiency of the coil.
