WARNING
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.
4. With the unit cold and pump running, lower the high fl uid pressure cutout
switch until the pump shuts down. Note the setpoint and raise by 10 PSI,
then re-start pump. The setpoint at cutout should correspond to the inlet
gauge reading.
5. With the unit running at operating temperature, lower the high outlet
pressure switch until the pump shuts down. Note the setpoint and raise
by 10 psi, then restart the pump. The setpoint of this switch should
correspond to the outlet pressure gauge reading.
NOTE:

Switch settings shall never exceed the safety valve set pressure.
 Gas Pressure Switch
NOTE:  Gas Fired Units Only
The high and low gas pressure switches are located on the gas train See Figure
24. The switches are used to ensure that the incoming gas pressure and gas
pressure to the burner are within the appropriate range.
1. While fi ring, shut the main gas ball valve closest to the burner.
2. Unit will lock out on high gas pressure.
3. Attempt restart by resetting fl ame programmer.
4. Unit will start purge and lock out.
5. Open the gas valve closest to the burner and reset fl ame programmer.
6. Reset high side of switch, unit will start purge and fi re.
7. To test the low gas pressure switch, close the incoming manual valve.
8. Allow the control to sequence.
9. When the gas valves energize, the heater should lock out.
10. Reset the low side of the switch/reset fl ame programmer and open the
upstream manual valve.
11. The unit will start purge and fi re.
 Operating Temperature Controls
The operating temperature control (Siemens, Fireye, Honeywell) are located
in the heater panel and regulate the cycling of the heater. On systems with
linkageless modulation, the operating temperature control and operating control
(fl ame programmer) are the same device.
1. The Coil Design unit is a fi red heat exchanger and the safe control and
monitoring of the thermal fl uid temperature is of vital importance. The safe
maximum temperature of the fl uid must be strictly adhered to.
2. When consulting fl uid manufacturer’s literature for the safe maximum fl uid
