signal strength from flame programmer or testing device. Operator attendance during
warm-up is a recommended precaution.
j) Start-up is considered complete when the unit begins to throttle back or shutdown on
target temperature.
16. Daily Shutdown
a) Set control switch to “Pump” pump running, burner off.
b) Allow the fluid to circulate for approximately 20-30 minutes and then set the control
switch to the “Off” position.
c) When using fluid cooled pump, continue to circulate cooling water to pumps for 30
minutes after stopping circulation.
d) Open power supply switches.
e) Units switched off by an automatic time switch should have an extra relay fitted to allow
20-30 minutes of fluid circulation after stoppage in order to prevent localized over heating
of fluid .
f) Close fuel valves if required. Closing of system valves is not generally necessary unless
maintenance of components requires a partial draining of the system.
g) Because of the high temperatures usually applied, leaks are not expected to occur when
cool down is achieved, provided pipework is free to contract naturally when cold.
