HEAT EXCHANGER COIL PRECAUTIONS
n
High mineral content in water may require a water softener installation.
n
Do not permit acidic, caustic or abrasive fluids to be pumped through system.
HEAT EXCHANGER COIL MAINTENANCE
n
Hard water conditions may eventually cause clogging in the heat exchanger coil if left unattended.
Scale deposits will compromise the heating efficiency and produce an unsafe condition over time.
It may be necessary to descale coil.
n
Scale buildup from certain detergents may eventually clog up the heat exchanger coil causing an
unsafe condition. Use only
recommended detergents for better cleaning efficiency.
n
Black carbon deposits that collect on the outside wall of the heat exchanger coil may be a result of
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.
FAILURE TO MAINTAIN HEAT EXCHANGER COIL MAY
RESULT IN A STEAM EXPLOSION WHICH MAY CAUSE
SERIOUS INJURY OR DEATH.
Burner Not Igniting No fuel Fill fuel tank with proper fuel
Burner switch turned off Turn burner switch on
Thermostat set too low Reset thermostat
