9. Watch plenum temperature as burner goes through a few cycles, to be sure that it is operating properly.
5. Operation
Light
Time Delay Operation - Standard Heater
HH-1089E Time Delay Reset Operation
The electronic time delay will indicate the operating condition of the heater through the LED light shown in Figure 5A. This light should be on the exterior control panel of the heater when the unit is installed correctly. This light is very helpful in identifying the status of the flame probe (open or closed) and will indicate a lock out condition.
Start-Up
The light should be ON when the ON/OFF switch is set to ON. This indicates that the heater has power and the flame probe is closed. The gas solenoid should open and ignitor should spark. The light will remain on until the flame probe opens. The light should go OFF if flame is established within the 30 second trial for ignition.
If flame is not present or the probe does not open, th en the light will blink continuously after the 30 second time period. It will blink continuously until the heater is reset.
Turn power OFF for 10 second to reset a lock out condition. The light will stop blinking after th e 10 second time period. The heater cannot be restarted if the light is blinking continuously.
Thermostat Cycle
The heater thermostat will cycle the gas solenoid OFF when temperature is reached. The flame probe should cool to a closed condition when this occurs. The thermostat will also cool to a closed condition with a drop in plenum temperature. The thermostat closure is a call for heat and the normal start-up for the time delay begins again.
A condition can occur where the thermostat can call for heat before the flame probe cools to a closed condition. The light ON the time delay will flash once at thermostat closure and remain OFF until the flame probe closes again. The heater will not operate until this “closed” condition of both switches is achieved.
Light Status Indication
Flame probe is closed.
ON
OFF
Time delay in 30 second trial for ignition period.

5. Operation
High-Low Heater Operation
1. High-Limit and cycling thermostat must be wired into heater control box for heater to operate.
2. Open all manual shut off valves to heater unit.
3. Start fan. This will supply power to heater.
4. Turn thermostat dial to its highest setting.
5. Turn toggle switch ON. Both lights should illuminate indicating power to the control circuit.
6. Heater should now be lit. If not check to see that all gas is ON.
7. Open adjustment screw on solenoid valve all the way.
8. Turn thermostat dial back slowly until heater cycles to low flame.
9. Adjust screw on solenoid valve so that low flame pressure is at desired setting. (As low as possible.)
10. Turn thermostat dial to desired setting and wait for bin plenum to come up to temperature. Heater should cycle to low flame after a few minute.
11. If heater does not cycle to low flame increase high flame gas pressure by adjusting the regulator.
12. High flame should be adjusted so the heater cycles 75% of the time. Low flame should be adjusted so there is enough flame for unit to keep operating.
13. Watch as burner goes through a few cycles, to be sure that it is operating properly back to high flame.
Figure 5B
5. Operation
Modulating Valve Operation
1. The modulating valve regulates gas flow through the heater ba sed on sensing unit in the plenum, and maintains a constant drying air temperature.
2. The sensing bulb of the modulating valve should be mounted through the bin wall with the side reading “top” up. The bulb reacts to temperature. It changes the amount of gas (increase or decrease), burning warmer or cooler depending on the position of the valve SET POINT. If the bulb is cooler than it was at the SET POINT, the bulb senses the cooler temperature and opens the valve further so more heat is applied to the drying air. If the bulb is warmer than it was at the SET POINT, the valve closes further and reduces the temperature until the air is at the valve SET POINT.
3. It is important that the pressure regulator be set high enough to allow the modulating valve to deliver enough gas to maintain the plenum temperature necessary. The regulat or is normally factory set at 15 PSI (propane units). To set the regulator, run the heater and turn the modulating valve T-handle in. This gets full line pressure to the burner. Then adjust regulator to read 15 PSI (depending on the plenum temperature needed).
4. Turn the fan/heater ON. To set the modulating valve, turn the T-handle out (counterclockwise) until loose and wait a few minute for the plenum temperature to equalize. When the temperature under the bin has equalized, gradually turn T-handle in (clockwise) about 1/2 turn at a time. Wait until temperature under bin has equalized as before. If temperature under bin is less than the desired temperature, continue turning T-handle in, increasing gas flow and waiting for plenum temperature to equalize until the desired temperature is the stable temperature of the plenum. If temperature under bin is the same 10 minute after you last made any adjustments to the T-handle you can be certain that the temperature under the bin is the SET POINT of the valve. 1 Turn of the T-handle
equals approximately 7°F of temperature.
5. The valve will now keep the plenum temperature at the set point regardless of ambient conditions as long as humidistat or thermostat do not shut down the heate r. A bypass orifice is used to maintain a small flame when outside temperature is near or above the set point of the valve. The bypass ensures steady application of heat at minimum gas flow operation. Bypass orifice will only operate correctly if pressure regulator is set correctly.
6. To observe how the modulating valve increases the efficiency of bin drying, check the gas pressure of the unit in the morning and compare to the pressure read mid-afternoon. If the ambient (outside) temperature is significantly greater later in the day (as normal), the ga s p r essure will be less. Sin ce less heat is required to maintain the same temperature in the plenum, the modulating valve will have reduced the amount of gas used by the heater.

5. Operation
Adjusting the Vaporizer
1. Vaporizer should be adjusted so the vapor pipe train runs warm to the touch (100°F-120°F).
2. Loosen 5/16" bolt on adjustment bracket.
3. Swivel vaporizer away from flame if running too hot, closer to flame if too cold.
4. Move vaporizer only 1" at a time and allow a few minute for temperature to equalize.
5. Tighten 5/16" bolt and watch heater run for several minute to verify adjustment.

6. Service

Always disconnect and lock out power before working on or around heater.
All heaters are constructed of durable weather-resistant materials, so a minimum amount of service should be required. Before the unit is started for the first time each season there are a few items that need to be checked out. All damaged parts should be repaired or replaced.
1. Disconnect and lock out power to fan/heater. Open control box lid and inspect all components for moisture, vibration or rodent damage. Inspect and tighten all loose terminal connections. Replace any damaged wiring.
2. Remove burner orifice tube and inspect for dirt or foreign material. Clean out if necessary.
3. Inspect holes in burner ring for possible corrosion or plugging with dirt or rust. Clean if necessary.
4. Be sure primary air inlet screen is intact and clean for proper burn.
5. Check perforated ring on natural gas models to be sure it is clean and no holes are plugged.
6. Inspect flame probe and ignitor and adjust or replace if necessary.

Burner will not fire. No gas pressure on gauge. Constant ignition spark.
Burner will not fire. Gas pressure on gauge. No ignition spark.
1. Heater not wired.
2. Fan not running. 2. Fan contactor must be energized for heater to run.
3. Blown fuse. 3. Visually check fuse.
4. Bad ON/OFF switch.
5. Housing high-limit switch. 5. Reset switch. Check for power on terminals 1 and 8.
6. Thermostat open.
7. Flame probe open.
1. Electronic time delay. 1. Time delay is in lock out or not receiving power.
2. Gas supply.
1. Loose wire.
2. Ignitor/spark plug.
3. Ignition transformer/wire.
1. Visually check fan control box to see if wires are connected.
4. Check ON/OFF switch contact block for proper
installation and continuity. Check for power on terminals 1 and 8.
6. Plenum temperature above set point temperature or
open circuit.
7. Remove wires from flame probe and check with ohm
meter. Probe should be closed when cold.
2. Make sure all valves are open to heater and gas tank is not empty.
1. Check for power on terminals 4 and 7. Look for loose
wires or incorrect wiring.
2. Turn gas OFF to heater. Check gap on ignitor. Check
porcelain for any sign of cracks. Remove plug wire from spark plug/ignitor. Carefully holding wire by insulation. Try to get an arc between end of wire and heater housing (or other wire using two (2) pole transformer).
3. Turn gas OFF to heater. If no spark present after
checking ignitor, remove wire from ignition transformer. Check for spark at ignition transformer with an insulated screwdriver. Spark should jump a minimum 1/4" gap. Replace transformer if no spark is established, replace the ignition wires.
1. Check for gas at burner. If no gas, remove pipe train and
check orifice and burner ring for blockage.
2. Check to be sure flame probe is in good condition and is
located in flame. Flame probe contacts should open when probe gets hot.
4. See that flame burns continuous and is not intermittent. On ring burners be sure flame burns completely around ring.
5. Have tank and lines checked by a qualified gas service man.
Burner will not fire or fires for 30 second and locks out. Gas pressure on gauge. Spark is ON.
1. Plugged orifice.
2. Flame probe.
3. Incorrect supply voltage. 3. Voltage to heater must be 110V AC.
4. Regulator set too low.
5. Moisture in fuel.
