document may substitute for full
review of documentation available
from the component manufacturer.
Do not operate, or allow others
to operate, service or repair this
equipment unless you (they) fully
understand all applicable sections
of this manual and are qualifi ed to
operate/maintain the equipment.
The end user of the heater must
maintain all labels on the heater
in clean, legible condition. All

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 a water 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.
