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).

Page 13
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
Page 14
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.

Page 15
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.
Chief Industries, Inc. 800-359-7600 COMPONENTS - 416274 Page 15
Page 16
C E N T R I F U G A L H E A T E R - C S A
29. Burner High Limit Wire (#9701961) - Wiring that connects the burner high limit and burner
exhaust limit to the control box.
30. Neutral Terminal Block 3 POLE (#850255) - This terminal block is used as a junction block to
establish a common neutral for connection of the neutral leads.
31. Venturi Weldment (#9415661) - The venturi weldment creates a high and low pressure area in the
airflow, which aids the air switch in measuring air velocity.
32. Humidistat Control (#9850982) - The humidistat control is an electrical operating control that is
wired into the heater to cycle the heater "On" and "Off" with respect to the relative humidity of the drying air. The humidistat control is typically set at about 50% - 60% relative humidity of the drying air. When the relative humidity is higher than the humidistat setting, the heater is cycled "On" and is left on until the relative humidity is below the humidistat setting. If the relative humidity of the drying air is less than the humidistat setting, the heater is cycled "Off" until such time that the relative humidity would become greater than the setting of the humidistat. The humidistat control is for low temperature drying.
33. Thermostat Control (#9851014) - The thermostat control is an electrical operating control that is
wired into the heater to cycle the heater "On" and "Off" with respect to the temperature of the drying air. The thermostat is set at a desired temperature, and if the drying air temperature is higher than the thermostat setting, the heater is cycled "Off." If the drying air temperature is less than the thermostat setting, the heater is cycled "On," and is left on until such time that the drying air temperature is above the thermostat setting.
34. Humidistat-Thermostat Control (#9870974) - The humidistat-thermostat control is an electrical
operating control that is wired into the heater to cycle the heater "On" and "Off" with respect to both the drying air relative humidity and temperature. The humidistat-thermostat control will cycle the heater on if either the drying air relative humidity is too high, or the drying air temperature is too low with respect to the humidity setting or temperature setting of the control. NOTE: The optional external plenum controls do not function in the same manner as a thermostat in a residential house. When the bin plenum controls reach the set point the heater is then shut off. In the off mode the
bin’s plenum temperature will drop below the set point of the control due to the rapid air change in
the plenum from the fan. The controls do not sense the instantaneous change in air temperature but take time to reach the plenum control setting before controlling the heater operation. NOTE: The firing rate must be set by the operator to verify excessive temperature is not present in the plenum.
35. Modulating Valve - The modulating valve is a non-electrical operating control. The modulating
valve is placed in the heater plumbing, and controls the amount of fuel burned by the heater depending upon the temperature of the drying air. If the temperature of the drying air is lower than the temperature setting of the modulating valve, the modulating valve opens up and more fuel is burned to raise the drying air temperature. If the drying air temperature is higher than the temperature setting, the modulating valve restricts the amount of fuel to the heater. The modulating valve has an interchangeable by-pass orifice to maintain continuous low heat operation regardless of modulating valve setting. The orifice is interchangeable for establishing lower or higher by-pass flow through the modulating valve, depending on conditions.

C E N T R I F U G A L H E A T E R - C S A
For proper operation of heater, the fan and heater are to be mounted on a level pad. The pad should be the same height as the concrete floor. The size of the pad should be as indicated in the following illustration.
Chief Industries, Inc. 800-359-7600 INSTALLATION - 416274 Page 21
Page 22
C E N T R I F U G A L H E A T E R - C S A
Before installing heater please verify the following:
1. That the spark plug is gapped at 1/8" (.32cm). If not, gap to 1/8" (.32cm).
2. That the flame probe and spark plug wires are attached.
3. That all bolts, including carriage bolts and screws are tight.
4. The heater is installed on the air discharge end of the fan. Check air flow decals on the fan and heater
to verify heater is oriented properly. Connect the heater to the transition with bolts provided in the fan bolt bag. The installation should appear as illustrated previously.

Gas Supply Installation

Refer to the dryer rating plate to locate the minimum gas supply pressure for obtaining the maximum gas capacity for which this dryer is specified.
The gas piping installer is to locate a manual emergency shutoff valve in an appropriate location that allows access to this valve in case of a fire, explosion or other emergency at the heater.
Propane Gas
Chief Industries, Inc. 800-359-7600 INSTALLATION - 416274 Page 22
Page 23
C E N T R I F U G A L H E A T E R - C S A
For a typical propane tank installation a 1000 gallon tank is recommended as the minimum size to avoid frequent refilling. (Raising the air temperature 100°F (38°C) on an airflow rate of 10,000 CFM (283m³/min) would require approximately 300 gallons of liquid propane per day.) Also the larger tank will aid in the vaporization of the liquid propane.
Note: Never use an anhydrous ammonia tank as your LP gas tank. Contaminants in the tank can be harmful
to the heater, and safety devices may not meet liquid propane storage codes.
The supply tank should be placed at least 10 (3.05m) from the heater. Because some areas may require a greater distance, please consult your local authorities.
The supply tank should be equipped with a liquid valve and vapor valve. The inlet of the liquid valve should be located 12 (31cm) from the tank bottom to avoid impurities getting into the gas line and heater.
The liquid valve and vapor valve on the propane tank should be connected as illustrated. This allows the operator to run the LPGE and LPGEM units on vapor or liquid propane.
A minimum 60 psig (414kPa) pressure regulator is recommended, located as shown. The regulator provides uniform flow, and reduces the pressure on the gas line from the regulator to the heater for added safety. The regulator is required on vapor and liquid propane installations. Verify that the supply tank has a relief valve present and that it is properly sized and located.
Chief Industries, Inc. 800-359-7600 INSTALLATION - 416274 Page 23
Page 24
C E N T R I F U G A L H E A T E R - C S A
Natural Gas
The natural gas service should be able to provide a minimum of 5 psig (34kPa) when the heater is operating. Check with your gas supplier to verify that the supply pressure has the pressure potential to deliver natural gas for the length of the service line.
A line strainer must be located at the heater (order part #714709).
The natural gas service should be regulated. Contact your gas supplier. A regulator can be obtained from Caldwell (order part #753905).
Fuel Line Installation
The suggested tubing size to be used from the supply to the heater is 5/8" (1.59cm) O.D. type K copper tubing or 1/2" (1.27cm) black schedule 80 steel pipe. If copper tubing is used, make a loop in the tubing within 3’ (0.9m) of the heater to absorb shock. If 1/2" (1.27cm) steel pipe is used, run the plumbing to within about 3’ (0.9m) of the heater, and use three feet of 3/8" (.95cm) minimum I.D. high pressure flexible hose, (CGA approved for propane). Be careful not to turn or twist the heater plumbing parts because the proper operation of these can be affected or leaks in joints can be developed. Verify all foreign material is out of the gas line before connecting the line to the heater.
If your natural gas supply pressure is not adequate to maintain 10 psig (69kPa) at the heater, use a one inch or larger service line and verify that 5 psig (34kPa) natural gas pressure is available when the heater is operating. Install a line strainer between the natural gas heater and the service line.
Check all connections for leaks with a soap test. Open the supply valve at the source and use a liquid detergent and brush all fittings and joints. If bubbles are generated at the fitting, gas is escaping from the joint. With the installation of the service line, inspect all parts that are added, and the heater plumbing parts affected by the installation. Tighten the components that are not sealing and replace if cracked or defective.
Note: Do not use galvanized pipe fittings.

High Limit Installation

The High Limit control is connected by conduit to the control enclosure of the heater. The High Limit will need to be installed into the bin plenum as shown in the following illustration. Install the high limit on the right hand side of the transition, 2’ - 3’ (.60m - .91m) from the transition, approximately midway up in plenum space under the drying floor. Drill a 4.0" (10.16cm) diameter hole centered on a valley of the bin corrugation. Next place the limit control in the 4.0" (10.16cm) hole and match drill (4) 7/32" (.55cm) diameter mounting holes located on the corrugation hill. Field seal around the high limit and fasten using (4) 1/4" (.64cm) sheet metal screws located in the bolt bag to secure the High Limit to the bin wall.

Fan Electrical Installation

C E N T R I F U G A L H E A T E R - C S A
Connect the fan unit to the electric power source following the recommended wiring procedure indicated in the fan manual. The electrical disconnect switch for the fan shall be sized with adequate ampacity for the fan rating and installed in accordance with the Canadian Electrical Code Part 1 (CSA Standard C22.1) and any local requirements.

Heater Electrical Installation

Note: The heater is electrically interlocked with the fan electrical service.
The heater operates on 115 volt, single phase, 60 cycle power. For fans wired for 230 volt, verify that the fan is wired with a neutral wire to the middle terminal of the fan terminal block (#2), as well as a ground wire linked to the bottom terminal of the fan terminal block (#3) as shown. The heater power cord is wired into the fan controls by connecting the black wire to the terminal (#1), the white wire to terminal (#2), and the green wire to terminal (#3) of the fan terminal block, as shown. With the heater wired into the fan circuitry, the fan must be operating before power is available to the heater.
Chief Industries, Inc. 800-359-7600 INSTALLATION - 416274 Page 25
Page 26
C E N T R I F U G A L H E A T E R - C S A
For fans wired for 460 or 575 volt, three phase power and 230 volt, three phase power, a step down transformer must be used to convert the 460 or 575 volt system and 230 volt system to 115 volt, single phase, 60 cycle power for the heater.
When installing a thermostat, humidistat, or thermostat-humidistat control, the control power cord is wired into terminals #6 and #7 of the heater terminal block. Remove the jumper wire linking terminals #6 and #7, and connect one lead of the control power cord to terminal #6 and the other lead to terminal #7. The control leads can be interchanged.

Installation of External Plenum Controls

For the proper installation of a thermostat, humidistat, or thermostat-humidistat control to the bin, the installation of a dual humidistat-thermostat kit, or the installation of a vaporizer or a modulating valve to the heater, refer to the installation instruction provided with each accessory.

Operating Instructions

Heater Control:

Information on the operating characteristics of the Centrifugal heater with a flame sensing system is outlined in the following illustration. The flame sensing relay is reset by de-energizing the heater circuit after a loss of flame condition.
Chief Industries, Inc. 800-359-7600 INSTALLATION - 416274 Page 26
Page 27
C E N T R I F U G A L H E A T E R - C S A
The operating characteristics of the flame sensing circuit are outlined as follows:
1. The flame probe is checked for proper functionality every time the heater is started. The heater
toggle switch is pushed to the “START” position. If the flame probe is in good condition, the purge light is illuminated. If the flame probe is not good, the flame probe will require replacement.
2. Once the flame probe is checked, the remaining internal and external heater sensors have power
available. If all sensors call for heater operation, after a 30 second time frame to complete the purge cycle, the transformers and solenoids are energized, and the ignition light is illuminated.
3. If no flame is at the burner or the flame probe is not positioned to monitor the flame, the flame
sensing relay will de-energize the solenoids and transformer after approximately 30 seconds. The flame lock-out light will be illuminated. The condition that resulted in the loss of flame at the flame
probe needs to be addressed. The flame sensing relay is reset by switching the heater power switch to
“OFF”.
4. The heater then can be restarted by repeating the operation steps.

Start-Up Procedure:

Note: The heater is designed to operate at various firing rates. The operator must adjust the firing rate for correct operation based upon the conditions present.
Chief Industries, Inc. 800-359-7600 OPERATION - 416274 Page 27
Page 28
C E N T R I F U G A L H E A T E R - C S A
Refer to the dryer rating plate to locate the minimum gas supply pressure for obtaining the maximum gas capacity for which this dryer is specified.
1. Verify all roof vents are open and unobstructed. Note: if freezing of roof vents could occur,
do not operate the system.
2. Verify all controls are installed correctly. Refer to the ratings plate for determining the
minimum gas supply pressure to achieve the maximum gas capacity for which the heater is specified.
3. Turn fan on by placing fan switch in an "On" position.
4. Open supply valve at the regulator. a. It is preferable to start liquid propane units on vapor fuel. (After warm up, open liquid
valve on the supply tank approximately 1 turn, and close vapor valve.)
5. Open liquid valve (on LPGE Heaters only).
6. Open vapor valve.
7. Turn heater on by placing toggle switch to “Momentary Start” then "On" position.
8. Open regulator at heater slowly to 2 psig (14kPa) fuel pressure for low temperature start.
9. Set plenum external controls for desired heater operation. (See adjustment section of this
manual for more information.)
10. Wait at least 40 seconds for ignition to occur. The heater has a 30-second pre-purge before
ignition.
11. Perform a gas leak check during start up to verify the gas tightness of the gas train components
and piping under normal operating conditions.
12. If burner fails to ignite in 40 seconds, close regulator and vapor valve and turn off the heater by
placing toggle switch to the "Off" position. (Refer to service section of this manual for trouble
shooting of heater.)
13. If the high limit shuts the burner off, the high limit indicator light will be illuminated. Once the
high limit has cooled to a lower temperature, the high limit is reset by turning the heater switch off and then back on. The repeated shutting off of the burner by the burner high limit is caused by excessive static pressure, lack of air flow or a firing rate set too high. Reduce the static pressure or air blockage before re-firing unit. If needed adjust the firing rate.

Drying Temperature Recommendations:

To determine the appropriate drying temperature, the crop to be dried and the drying system used must be established. When this information is known, refer to the following table for the recommended maximum plenum temperatures.
In using the recommended drying temperatures please be aware of the following information:
1. The rate of drying is increased with increased temperature, however susceptibility to grain
damage also increases.

2. Wet grain will remain relatively cool due to moisture evaporation from the kernel, however dry
grain will warm to the drying temperature.
3. The drying front moves from the base of the bin upward. When operated as a batch system and
when a stirring machine does not reach the floor, significant over drying can occur at the base of the bin.
4. When drying grain and focusing on kernel quality, use as low a plenum temperature as possible.
Note: Do not automatically set the plenum temperature at the maximum recommendation.
5. When the grain is nearly dry, reduce the plenum temperature to complete the drying. This will
reduce the quantity of cracked grain generated and reduce the fire hazard.
6. When drying sunflowers, exercise caution because sunflowers are very flammable. Do not
exceed the temperature recommendations. Also, be aware that the chaff from sunflowers is very flammable. Good housekeeping in the plenum chamber and around the bin is essential.
- Note: Temperature recommendations are based on non-seed crops (to be marketed
commercially). For seed crops, do not exceed 110°F (43°C), except for pinto beans
do not exceed 100°F (38°C).
- For other crops contact your extension service or Chief for drying temperature
recommendations.

Adjustments:

The following adjustments will have to be made, depending upon the kind of heater and plenum external controls being used. These adjustments cannot be made at the factory due to the differences in bin setups, drying methods, and weather climates. These adjustments should be checked at least twice a day or every 6 hours of operation to verify that the heater is functioning properly, and that the desired results are being achieved. In using the recommended drying temperatures keep the following considerations in mind:
Vaporizer Adjustment
The vaporizer is used on LPGE units and is located in the flame established by the burner. The vaporizer uses heat from the burner to convert the liquid propane at the vaporizer entrance to vapor propane. The burner requires vapor propane for proper operation.
The vaporizer outlet is connected to the vapor plumbing line by a vapor propane hose. The temperature of the vapor plumbing line is sensed by a vapor limit thermostat, which will cycle the heater off if the temperature exceeds 160°F (71°C). The proper location of the vaporizer will establish a vapor plumbing line temperature of about 110°F (43°C). At this temperature, the vapor plumbing line should be warm to touch. If the temperature of the vapor plumbing line is too low, move the vaporizer into the flame by loosening the square headed setscrew holding the vaporizer in place, adjusting the vaporizer location and re-tightening the setscrew. If the temperature of the vapor plumbing line is too high, the vaporizer should be moved out of the flame with the procedure indicated above.
Regulator Adjustment
The regulator should be set at the firing rate required. This can be done by first setting the heater to the desired firing rate with the vapor valve, then reopening the vapor valve and adjusting the regulator by turning the adjusting screw until the pressure gauge shows the desired pressure at the desired firing rate.
When setting the heater at the desired firing rate, the operator must take into account the heater size, the static pressure the fan is working against, the ambient temperature, orifice size, and fuel used and the type of plenum control. Refer to operation instructions that are supplied with the humidistat, thermostat, or modulating valve. The Firing Rate Tables of this manual are set up to help the operator select the desired firing rate.
Humidistat Control Adjustment (Heater Operation)
Set the humidistat control at the desired setting (50% - 60% relative humidity is recommended). To obtain even drying, adjust the firing rate of the heater unit so that the humidistat maintains a constant humidity of the drying air. The heater should be set at a firing rate of approximately 2 psig (14kPa) for propane, or 1 psig (7kPa) for natural gas, and then be adjusted to maintain correct operation of the heater. The heater firing rate must be checked as humidity conditions change.
Thermostat Control Adjustment (Heater Operation)
Chief Industries, Inc. 800-359-7600 OPERATION - 416274 Page 30
Page 31
C E N T R I F U G A L H E A T E R - C S A
Set the thermostat control to the desired temperature setting. Initially, set the firing rate of the heater at 2 psig (14kPa) pressure for propane, or 1 psig (7kPa) pressure for natural gas. To obtain even drying, adjust the firing rate of the heater unit so that the thermostat calls for heat 90% of the time. The heater firing rate must be checked as temperature conditions change.
Warning: The plenum thermostat is used as a drying thermostat, not as a plenum high limit.
Humidistat - Thermostat Control Adjustment
1. Humidistat Control Only
Set the thermostat at the lower temperature limit. This is the temperature wanted for heater operation, whether the humidistat is calling for heat or not, 40°F-50°F (4.4°C-10°C) is recommended. Set the humidistat and heater according to the humidistat instructions previously given.
2. Thermostat Control Only
Set the humidistat at 100% relative humidity. Then adjust the thermostat and heater controls according to the thermostat instructions given.
3. Humidistat - Thermostat Combination
Set the humidistat and thermostat at the desired operating conditions. Then adjust the firing rate of the heater according to the humidistat and thermostat instructions.
Modulating Valve Adjustment (Heater Operation)
The modulating valve is used to maintain a constant plenum temperature by allowing more gas to flow to the burner if the plenum temperature is lower than desired, or by restricting the gas flow if the temperature is higher than desired.
To set the modulating valve, use the following procedures:
1. Determine what plenum temperature is desired.
2. Using the vapor valve, set the operating pressure at 8 psig (55kPa) for propane, or 3 psig
(21kPa) for natural gas.
3. Adjust the "T" Handle of the valve until the bin thermometer maintains the desired plenum
temperature. The handle is turned in, (clockwise) to get a higher temperature, or out (counter­clockwise) to get a lower temperature.
4. Set the regulator 2 psig (14kPa) higher than the modulating valve operating condition, by
turning the modulating valve handle in (clockwise) 2 revolutions, adjusting the regulator to the desired pressure, and then resetting the modulating valve to the desired plenum temperature

Shut Down Procedures

If the heater is to be shut off for a prolonged period, carry out the following steps:
Chief Industries, Inc. 800-359-7600 OPERATION - 416274 Page 31
Page 32
C E N T R I F U G A L H E A T E R - C S A
1. Close the fuel valve at tank.
2. Allow the fuel to be burned out of the fuel line.
3. After the flame burns out, close vapor valve, regulator valve and liquid valve.
4. Turn off heater, placing toggle switch to "Off" position.
5. Allow fan to run for 2 minutes in order to cool off heater. Next shut the fan off. Finally shut
off the power at the fan service disconnect.
6. The thermostat or humidistat external plenum controls should be removed and stored in a
clean, dry place.

Firing Rate Guideline Tables

The following tables are to be used as a guide for setting the firing rate of the heater. The values are an estimate - the actual values may vary, depending upon the bin setup and weather conditions. Once the predicted firing rate is obtained, a bin thermometer should be used to determine the actual plenum temperature, and then the firing rate should be adjusted to obtain the desired plenum temperature. Use the following procedures in conjunction with the "Drying Temperature Recommendations", in determining the firing rate needed for your application:
1. Determine the ambient temperature at which the heater will be operating (e.g. the outside air
temperature).
2. Find the difference of the desired drying temperature and the ambient temperature. This value
is the temperature rise desired.
3. Use a static pressure gauge to determine the static pressure at which the fan and heater are
operating.
4. Refer to the following tables which list the size of your heater, the gas used, and the temperature
rise desired. Locate the required firing rate for the operating static pressure.
5. If the ambient temperature is 50°F (10°C), then the firing rate can directly be read for your
heater, gas used, and plenum temperature for 50°F (10°C) ambient air.
Note: As conditions vary, the firing rate should be adjusted to obtain the desired plenum
temperature.

Heater Maintenance

The following procedures should be followed and maintenance performed before starting the unit at the beginning of every season, and also during operation:
1. The fuel line strainers should be taken out and cleaned. A plugged screen will restrict the gas
flow to the unit. On liquid propane units, liquid and vapor line strainers both should be checked. Warranty is void if the strainer or screen is removed, and not reinstalled after cleaning.
2. The burner should be checked for obstructions and debris. To check, use a piece of wire or drill
bit that will fit the holes in the burner. To clean the inside of the burner, remove from the heater and tap lightly around the burner. Then pour the foreign material out of the inlet.
3. The air switch inlet screen should be cleaned. This screen keeps debris from entering the air
switch; however, during operation the screen can become clogged or dirty.
4. Check all plumbing joints for leaks using the "soap test." The gas tightness of the gas train
should be checked at least on an annual basis. (See previous installation instructions).
5. Check all wires to verify they are not bare or causing a short. Pests can destroy insulation on
wires, including the spark plug, flame probe, burner limit wires if protective measures to control rodents are not implemented.
6. Examine and gap spark plug. Through wear, the spark plug can go out of adjustment. Verify
during operation every two days. The gap of the plug should be 1/8” (.32cm).
7. The flame probe needs to be checked to be sure that it has not been burnt off due to lack of
proper adjustment in and out of the flame. The flame probe can also become damaged. Verify every two days during operation and replace or adjust as needed. (See adjustment section).
8. Check all wire connections to be sure they are tight.
9. All external plenum controls (nylon humidistat or thermostat combination) should be inspected,
cleaned, and checked every three days during operation.
10. Caldwell recommends that external plenum controls be removed and stored in a clean, dry place
when not in use.
11. Check adjustment of the vaporizer twice daily, or as changing weather conditions demand. (See
heater adjustment section).

Servicing the Heater:
The following will help you find any problems that may occur in the heater unit and includes tips for repair. For servicing of electrical systems, open the control box cover. Inside the cover you will find a wiring schematic to help you service the unit. In the checks shown below, locate the symptoms you are experiencing with your unit and follow the list of corresponding possible causes and remedies:
Note: Unless otherwise indicated, checks are made with the power off using a voltmeter on resistance
setting.

Generic Sequential Operations Check:

1. Lack of power going to the unit (check made with power on). a. Take a voltmeter or continuity tester, put one lead to ground and the other on the top
terminal of terminal block in fan control box. Power lead is the black wire on the top terminal (#1) on the terminal block. When the fan is operating, it should indicate 115 volts on the voltmeter or the light should come on using a continuity tester.
2. Improper Neutral. a. Verify neutral wire is connected to the terminal block in the fan control box. Neutral to
be provided from disconnect to fan control box with the power supply.
3. Fuse may be blown. a. Visually check fuse. If dark in color, replace. b. Check fuse and holder. Put one lead on each side of the fuse on the fuse holder screws.
Meter should show continuity through fuse.
4. Check for power at toggle switch in heater (check made with power on). a. Put one lead of voltmeter to toggle switch where power cord is connected and the other
lead to ground. If there is not any power, check cord and fuse for damage.
5. Flame probe may be in an open condition. Note: The heater control is wired to check the
continuity of the Flame Probe each time the heater is started. If the Flame Probe is in an open condition, the Flame Probe will prevent heater operation. Verify all wires are connected properly.
a. Use a voltmeter and check for continuity across the flame probe. If no continuity is
present and the flame probe has cooled down, replace the flame probe. Check the wires to the flame probe. If they are damaged replace the flame probe wire.
6. Thermostat or Humidistat control may be open. a. Use a voltmeter and check continuity across the terminal block where the 2 leads of the
control are connected (terminals 6 and 7).
b. If no continuity is present, check the control setting to call for heater operation. Check
for damaged wires to the control. If either wire is damaged replace the wire. Replace entire thermostat or humidistat.
7. The vapor limit switch may be defective (LPGE units only)
Chief Industries, Inc. 800-359-7600 MAINTAINENCE - 416274 Page 40
Page 41
C E N T R I F U G A L H E A T E R - C S A
a. Use voltmeter and check continuity between terminals 5 and 6 on terminal block. If
there is no continuity, replace switch. (Verify that the vapor limit switch has had sufficient time to cool and automatically reset).
8. Air switch may be defective. a. With the fan running, check continuity across the air switch. If no continuity is present
and the fan is delivering air, the problem is in the air switch or in the venturi.
b. Verify the screen on the venturi is not plugged. If the fan is working against 4" static
pressure or lower, the heater should operate.
9. High limit may be closed. a. Use voltmeter to check for continuity between the two leads going to high limit channel.
(Terminal #1 on the terminal block and #3 on the start relay.)
b. If there is no continuity, remove the sensor from the bin. Check the switch individually
by putting leads of voltmeter on the two screws that have wires attached. The switch should not show continuity. Replace switch if defective. If switches are functional, the limit wire is defective. Replace damaged wire.
10. Flame sensing relay is not completing the circuit. a. Turn off switch to de-energize the circuit. Check the continuity of the contacts of the
relay. Check for continuity in the normally closed set of contacts (2 and 4, also 5 and 7). A lack of continuity indicates a defective relay. Replace the relay.
b. Supply power (115V and neutral) to the coil (terminals 1 and 8). Check power at the
normally open set of contacts (2 and 3, also 6 and 7). After power has been supplied to the relay for 30 seconds, power should be present at the terminals. If not, replace the relay.
11. Purge delay may be defective. a. Turn off switch to de-energize the circuit. Check the continuity at the contacts of the
relay. Check for continuity in the normally closed set of contacts (2 and 4, also 5 and 7). A lack of continuity indicates a defective relay. Replace the relay.
b. Supply power (115v and neutral) to the coil (terminals 1 and 8). Check power at the
normally open set of contacts (2 and 3, also 6 and 7). After power has been supplied to the relay for 30 seconds power should be present at the terminals. If not replace the relay.
12. Check all wires and connectors to verify they are functional and installed correctly. a. See wiring schematic for correct installation.

Condition Specific Faults:

1. Symptom: No ignition, Lack of ignition spark, Gas is present. a. Transformer is defective (power on).
i. Take the cap holding the spark plug wire off and remove the spark plug wire
from the transformer. With the transformer energized, ground an insulated
Chief Industries, Inc. 800-359-7600 MAINTAINENCE - 416274 Page 41
Page 42
C E N T R I F U G A L H E A T E R - C S A
screwdriver and arc to the transformer post where spark plug wire was
connected. Caution: Do not touch the screwdriver shaft.
ii. If no arc is present or is less than 1/8” (.31cm) replace transformer.
b. Spark plug wire is defective (power on).
i. Take wire off spark plug and arc to heater. Caution: Do not touch the
mounting terminal of the spark plug wire. If no arc is present or is less than 1/8” (.31cm) replace wire.
c. Spark plug is defective
i. Check gap of plug. Verify gap is 1/8” (.31cm).
ii. If transformer and spark plug wire are functional replace the spark plug.
2. Symptom: No ignition, Lack of gas with spark present. Note: The check to verify gas is
present should be made after all the electrical component checks are made, and the electrical
controls are confirmed to be functioning properly. Note: that the purge delay develops a 30 second delay for the solenoids to open.
a. Lack of gas to the heater.
i. Check tank to see if ample pressure is available to start unit. Unit requires 35
psig (241kPa) of propane pressure and 5 psig (34kPa) of natural gas available at the unit for startup.
ii. Check to see if the tank, regulator, or line going to the unit is blocked.
b. Check to see if the solenoids are functioning.
i. (Power On) Put your hand on the top of the solenoid and turn the heater toggle
switch on and allow 30 seconds for the purge. If you feel a click at the top of the solenoid, the coil is functional and the solenoid is working electrically. If there is no click, the coil is defective and should be replaced.
ii. (Power Off) Check solenoid to see if screen is plugged or the diaphragm is
defective. Unscrew the top of the brass fixture and locate the screen and diaphragm inside. Be sure to reassemble properly. Reversing any parts in the solenoid will cause the solenoid not to function properly. Keep all foreign material out of the solenoid.
c. Obstruction in the gas line.
i. Install pressure gauges at available locations in the plumbing line to determine
where a fuel restriction could exist.
d. If gas is present at the pressure gage but unit lacks gas for ignition.
i. Check orifice size, and be sure it is clean. (See Firing Rate Tables.)
ii. Check burner. See that holes are not plugged. See that the tubing isn't plugged
by debris.
3. Symptom: Flame sensing relay locks ignition out. a. If ignition is not present.
Chief Industries, Inc. 800-359-7600 MAINTAINENCE - 416274 Page 42
Page 43
C E N T R I F U G A L H E A T E R - C S A
i. Refer to the steps outlined previously in: “Condition Specific Faults/No ignition,
Lack of gas with spark present” and “Condition specific Faults/No ignition, Lack of ignition spark, Gas present”
b. If ignition is present.
i. Check position of the flame probe for proper adjustment.
ii. Defective flame probe. When flame is present, the flame probe contacts should
be in an “open” position. If contacts are “closed”, replace the flame probe.
iii. Check flame probe wire and replace if defective. Check wire for bare spots and
shorts to ground. Flame probe should not show continuity from either wire to ground. Check the two wires in the flame probe wire assembly to see if they are shorting across in the assembly. With the wires removed from the flame probe, there should be no continuity.
c. Defective flame sensing relay (power on).
i. With the switch off, shut off gas supply at heater plumbing with ball valve. Push
the switch to the start position and release. Remember that there is a 30 second purge delay. After the 30 second purge delay, the flame sensing relay should have power to the coil for an additional 30 seconds. After 30 seconds elapses the circuit collapses and the flame lockout light turns on. If the coil does not activate the contacts within 30 seconds, or the light does not illuminate afterwards, replace the flame sensing relay.
4. Symptom: High limit is activated. a. Fan limit may be obstructed. Keep the fan screen clean of all foreign material. b. Fan motor may be failing. Check the motor to verify that it is obtaining full speed. c. Verify that static pressure is not excessive with a static pressure gage. Verify that roof
vents are open and are sufficient in size and quantity. Check the aeration floor for plugged holes. Verify the grain depth, moisture content and fines in the grain. If any of these conditions are high the grain level should be lowered.
d. Firing rate may be too high for the application. Reduce the firing rate.
5. Symptom: Heater cycles without any external plenum controls in place (power on). a. Static pressure is too high, causing the high limit to cycle the unit.
i. Remove vapor temperature limit from the vapor plumbing line. If unit
continues to cycle, check the following:
1. The vent area in the bin roof is insufficient. Verify that roof vents are
open and are sufficient in size and quantity. Check the aeration floor for plugged holes. Verify the grain depth, moisture content and fines in the grain. If any of these conditions are high the grain level should be lowered.
2. The firing rate is too high for the application. Reduce the firing rate.
b. The vaporizer is too hot.
Chief Industries, Inc. 800-359-7600 MAINTAINENCE - 416274 Page 43
Page 44
i. Remove vapor temperature limit from plumbing line. If cycling stops, adjust
vaporizer out of the flame.
6. Symptom: Not enough heat. a. Orifice is too small or dirty.
i. Check the firing rate table for the proper size orifice for your unit and
application.
ii. Remove orifice and check for obstructions then reinstall the orifice.
b. Insufficient gas pressure.
i. Refer to the installation section for proper gas supply.
c. Vaporizer is not hot enough.
i. Vapor plumbing will be cold to the touch. Refer to the adjustment section.
7. Symptom: External plenum control not functioning. a. Check wiring schematic and be sure the control is wired to the heater properly. b. Make a visual check of the external plenum control cord for cuts or shorted wires. c. Check the external plenum control setting. Adjust the control for the desired settings,
referencing the adjustment section.
