Heater and Control Enclosure Components
The following outlines the accessories, general components and replacement part numbers for the
Caldwell heater models.
Accessories:
1. A humidistat, thermostat, or thermostat-humidistat control is not included with the standard heater.
These controls are to be ordered separately. A dual humidistat-thermostat kit can be ordered so that
one control assembly can be used when two heater units are used on the same bin.
2. Caldwell requires using a fuel line strainer in the fuel line just before the fuel enters the heater
plumbing. A line strainer is provided on all units. A line strainer can be obtained from Caldwell, or
your gas company. Caution: Your warranty could be jeopardized if the heater should malfunction
due to foreign material in the heater plumbing lines if the fuel supply line is not fitted with a line
strainer.
3. When wiring a heater to a 460 or 575 volt fan, a step down transformer must be used to develop 115
volt, single phase, 60 cycle power (part #9717033).

Explanation of Components:
Please note the location and general description of the primary components and their function.
Control Enclosure Components:
Chief Industries, Inc. 800-359-7600 COMPONENTS - 416274 Page 12
Heater Body Components:
C E N T R I F U G A L H E A T E R - C S A
The balloon callouts shown in the above illustration specify each component of the heater.
1. 5 Amp Fuse (#850412) - The fuse protects the heater control circuit from excessive current draw.
2. Toggle Switch (#710707) - The toggle switch is the heater "On" and "Off" and “Momentary Start”
switch.
3. Start Relay (#756692) – A start relay is utilized to prove that the flame probe is functioning properly
with every trial for ignition. If the flame probe is functioning properly the relay allows the purge to
energize. If the flame probe is not functioning properly the start relay prevents the initiation of the
ignition process.
4. High Limit Relay (#756692) – The high limit relay is activated by the high limit. The slave relay
shuts off the spark and fuel to the burner and maintains the off condition until the operator
Chief Industries, Inc. 800-359-7600 COMPONENTS - 416274 Page 13
C E N T R I F U G A L H E A T E R - C S A
determines the reason for the high limit activation. The slave relay is reset by turning the heater
toggle switch to the off position.
5. High Limit (#776443) - The high limit control, located in the bin plenum, is a manual resetting
temperature limiting control, used to protect the heater, not the bin plenum, from excessive heat.
The high limit control activates the slave relay to shut off the heater if the plenum temperature
reaches 230° F (110° C). Note: The high limit is not an operating control; the operator must utilize
an operating control to set the firing rate for the desired drying plenum temperature.
6. Air Switch (#785691) - The air switch is a control that senses the flow of air from the fan to the
heater. If, for any reason, the air flow is stopped, the air switch will shut off the heater. The air
switch will keep the heater shut off until air flow from the fan is re-established. If the air switch cycles
off from a lack of air, turn the heater toggle switch off before restarting the fan.
7. Vapor Temperature Limit (#157200) - The vapor temperature limit is an automatic resetting
temperature limiting control used to protect the solenoid valve and regulator from being damaged
due to excessive gas temperature coming from the vaporizer. Also, the vapor temperature limit
protects the vaporizer from re-cracking the propane and causing an oil film to deposit on the burner.
The vapor temperature limit is set to shut off the heater if the gas from the vaporizer reaches a
temperature of 160°F (71°C). The control will allow the heater to reignite after the vaporizer cools.
The vapor temperature limit is only on LPGE heaters.
8. Purge Delay with 30 sec Time Delay (#719914) - Purge delay is a time delay relay used to delay the
energizing of the ignition transformer and solenoid valves for 30 seconds after the heater is turned on
to allow for the removal of any raw gas from the heater before ignition is tried. The purge delay calls
for a 30-second delay before ignition, regardless which control is sued to turn the heater on.
9. Flame Sensing Relay with 30 sec Time Delay (#719914) - The flame sensing relay has a 30
second delay and is used to break the circuit to the solenoid valves and ignition transformer if the
flame probe does not establish the presence of the flame at the burner. The operator will have to
manually reset the flame sensing relay by moving the power switch to off, before retrying for ignition.
10. Flame Probe (#749812) - The flame probe is a switch that is sensitive to heat, and is used to
establish the presence or absence of flame at the burner. The flame probe is used with the flame
sensing relay, as the flame safeguard circuit of the heater. The switch is opened on temperature rise.
11. Solenoid Valves - Solenoid valves are shut-off valves that are electrically operated. The valves are
opened automatically when energized, and are closed automatically when de-energized.
12. Ignition Transformer (#851790) - The ignition transformer is a transformer used to create the
6,000 secondary volts necessary for spark at the spark plug.
13. Spark Plug (#851402) - The spark plug is used to ignite the fuel at the burner. The spark plug will
spark while the ignition transformer is energized.
Chief Industries, Inc. 800-359-7600 COMPONENTS - 416274 Page 14
C E N T R I F U G A L H E A T E R - C S A
14. Fuel Line Strainer - The fuel line strainer is used to remove foreign particles from the fuel before
the fuel enters the heater plumbing. If these particles are not removed, possible operating difficulties
could occur.
15. Vapor Valve - The vapor valve is used for preliminary adjustment of the firing rate by opening and
closing the valve to generate the proper plenum temperature. Once the proper firing rate is
established, the regulator needs to be adjusted to the firing rate that is required.
16. Regulator - The regulator is used to regulate the firing rate of the heater. The regulator is not used to
regulate the fuel from the fuel sources. A separate regulator should be used for regulating the fuel at
the fuel source.
17. Pressure Gauge - The pressure gauge is used to indicate the amount of fuel pressure at the orifice.
The pressure is used as a tool to set the firing rate.
18. Orifice - The orifice is an opening at the end of the heater plumbing that develops a restriction to gas
flow, which allows the pressure gauge to develop a pressure reading, so that the firing rate of the
heater can be field set.
19. Liquid Shut-Off Valve (#714949) - The liquid shut off valve is used as a manual shut off valve and
is used to stop fuel from entering the heater. The liquid shut off valve has only two positions: open
or closed. The liquid shut off valve is only on LPGE heaters.
20. Vaporizer (#9752584) - The vaporizer is used on LPGE heaters only, and is used to convert the
liquid propane gas to propane vapor gas by using the heat supplied by the burner.
21. Hydrostatic Pressure Relief Valve (#716878) - The hydrostatic pressure relief valve is used to
protect the heater plumbing components from excessive fuel pressure by relieving the excessive fuel
pressure from gas trapped between shut off valves to the atmosphere. If a hydrostatic pressure relief
valve opens, replace the relief valve.
22. Burner - The burner is a component in the heater where the fuel and air are mixed and then burned.
23. Terminal Block 8 POLE (#749614) - The terminal block is used as a junction block for connecting
the lead wires of the various electrical parts.
24. Toggle Switch Protective Boot (#712034) - The toggle switch boot is used to eliminate water
entering the heater controls through the toggle switch.
25. Flame Probe Wire - The flame probe wire is used to connect the flame probe to the control box.
26. Spark Plug Wire - The spark plug wire is used to connect the spark plug to the ignition transformer.
27. Liquid Propane Hose (#715276) - The liquid propane hose is used to connect the liquid plumbing
line to the inlet of the vaporizer.
28. Vapor Propane Hose (#155820) - The vapor propane hose is used to connect the vaporizer to the
vapor propane line.
