6.1 SERVICE
HINTS
a. This boiler has been designed to provide years of trouble free performance under normal operating
conditions. However, the owner should conduct a general external examination at the beginning of
each heating season and at mid-heating season to assure good working performance is continued. In
addition, a qualified service technician should examine the boiler at least once every year.
b. Do not store anything against the boiler or allow dirt or debris to accumulate in the area immediately
surrounding the boiler.
c. Elements will burn out if the boiler is not filled with water when electrical power is turned on. Do not
connect thermostat wires until system has been filled with water. Water should be drained out from
system only when absolutely necessary to make repairs or prevent freeze-up during extended cold
weather shutdown.
d. The pressure & temperature gauge on the system should be checked frequently. During normal
operating conditions, pressure should be relatively stable throughout the heating season. If pressure
under normal operating conditions consistently rises and falls over a period of time, this can indicate
a fill valve leak, system leak or expansion tank malfunction. Leaks anywhere in the system must be
repaired without delay. If any leaks or significant pressure fluctuations are observed, call for service
immediately.
