!
WARNING
Electrical shock hazard. Turn OFF electrical
power supply at main power switch before
servicing unit. Service shall be preformed by a
qualified service agent. Failure to do so could
result in death or serious injury.
1.
Boiler is designed to provide years of trouble free
performance under normal operating conditions.
Conduct general external examination at beginning
of each heating season and at mid-heating season
to assure good working performance continues. A
qualified service technician should examine at least
once every year.
2. Do not store anything against boiler or allow
dirt or debris to accumulate in area immediately
surrounding boiler.
3.
Elements will burn out if boiler is not adequately
filled with water when electrical power is turned
on. Do not connect thermostat wire until system
has been filled with water. Drain water out of
system only when absolutely necessary to make
repairs or prevent freeze-up during extended cold
weather shutdown.
4. Check temperature and pressure gauge
frequently. During normal operating conditions,
pressure should be stable throughout heating
season. If pressure under normal operating
conditions consistently rises and falls over period
of time, this can indicate fill valve leak, system
leak, or compression tank malfunction. Leaks
anywhere must be repaired immediately. If leaks
or significant pressure fluctuations are observed,
call for service immediately.
5.
Test safety relief valve for proper operation.
Refer to valve manufacturer's instructions
packaged with relief valve.
6.
Check field entrance wire connections to unit for
any signs of looseness or over heating. Verify
wire lugs are securely tightened.
7.
Check all heating element wiring for signs of dark
or damaged connections. Replace if any sign of
failure exists.
8.
Ensure all wire connections are tight.
