SECTION 3
3-28
Daily Start-Up
1. Check positioning of all system valves to ensure fl ow is
not dead-headed.
2. Visually check relative position of minimum level fl oat
switch in the combination tank.
3. Turn on power supply switches.
4. Where applicable, open water cooling valve and check
that water fl ows correctly. (For water cooled pumps
only.)
5. Set three position switch to “Pump”. Push and hold
manual pump start button, monitoring pressure gauges
on heater.
6. When ready to begin heating, move three position
switch from “Pump” to “Heat”. After a short delay
resulting from the purge period, the burner will ignite.
Make sure that the temperature setpoint is as desired.
7. On gas units, pilot valve activation will be indicated
after pre-purge cycle has completed, followed by
main fl ame activation. Check the presence of the
fl ame by observing fl ame signal strength from fl ame
programmer or testing device. Operator attendance
during warm-up is a recommended precaution.
8. Start-up is considered complete when the unit begins
to throttle back or shutdown on target temperature.
Daily Shutdown
1. Set control switch to “Pump” pump running, burner off .
2. Allow the fl uid to circulate for approximately 20-30
minutes and then set the control switch to the “Off ”
position.
3. When using fl uid cooled pump, continue to circulate
cooling water to pumps for 30 minutes after stopping
circulation.
4. Open power supply switches.
5. Units switched off by an automatic time switch should
have an extra relay fi tted to allow 20-30 minutes of fl uid
circulation after stoppage in order to prevent localized
over heating of fl uid.
6. Close fuel valves if required. Closing of system valves
is not generally necessary unless maintenance of
components requires a partial draining of the system.
7. 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.
Before Leaving the Installation
1. Check all controls to insure they are operating properly.
Cycle the heater several times by raising and lowering
operating temperature on the thermostat.
2. Make sure the installation complies with all applicable
codes.
