SAFETY ALERT DECALS

INSTALLATION

Liquid Propane Models

Deluxe Centrifugal Heater

Fuel Connection

Important! Do not use propane tanks which have previously

been used for ammonia unless they have been purged accord-

ing to procedures of the National L. P. Association.

Be sure fuel supply system complies with all local codes

for L. P. gas installations.

1. LP models are designed to run on liquid pro

pane, with liquid draw from the propane tank.

Avoid using propane supply tanks that have

been used for vapor draw for long periods of

time. When using liquid draw systems any mois-

ture that may be present in tank or lines may

freeze when system is used in cold weather. To

avoid this, the usual precaution is to purge the

system with methanol.

2. Run proper size line (see specifications) to liq-

uid pipetrain on heater. Have a qualified gas

service man inspect installation to be sure that

everything is installed according to local codes

and ordinances.

3. After installation is complete check all connec-

tions for leaks with liquid detergent or compa-

rable. Wear rubber gloves and eye protection.

Avoid contact with liquid propane. DO NOT USE

FLAME FOR LEAK TESTING.

Propane Vapor Models

2. Run proper size line (see specifications) to pipe-

train on heater. Have a qualified gas service

person inspect installation to be sure everything

is installed according to local codes and ordi-

nances.

3. After installation is complete check all connec-

tions for leaks.

DO NOT USE FLAME FOR LEAK TESTING.

(See above for other precautions.)

Natural Gas Models

1. Natural gas models are similar to vapor models,

but have a larger orifice to accommodate

lower pressure sometimes found with natural

gas.

2. Run proper size line (see specifications) to pipe-

train on heater. Have a qualified gas service

man inspect installation to be sure everything is

installed according to local codes and ordi-

nances.

1. Propane vapor models are designed to run di-

rectly off of supply tank or from a separate ex-

ternal vaporizer.

3. After installation is complete check all connec-

tions for leaks. DO NOT USE FLAME FOR

LEAK TESTING. (See above for other precau-

tions.)

SECOND HEATER INSTALLATION

For Units Using HF-7318 Control Board

2 Deluxe heaters may be connected to one grain drying system and wired so they cycle together. One of the heaters should have a thermostat connected to it as per the installation instructions. That heater will be referred to as the master. The other heater (without the thermostat) will be referred to as the slave.

Installation For

Standard Units

1. Install relay base (TD-100283) in master heater control box.

2. Connect wire between term 6 on circuit board and terminals 14 on relay base in master heater.

3. Connect wire between term 13 on relay base and terminals 8 on circuit board in master heater.

4. Run 2 wires (18 gage) between master and slave heaters.

5. Connect wires to terminal 5 and 9 (points A and B) on relay base in master heater.

6. Connect wire from terminal 9 in master to terminal 14 (point F) in slave unit.

7. Connect wire from terminal 5 in master to terminal 15 (point E) in slave unit.

8. Install relay (TD-100282) in relay base.

Additional Steps For

Hi-Lo Units

1. Run 2 wires (18 gage) between master and slave unit.

2. Connect wires to terminals 21 and 22 (points C and D) on circuit board in main heater.

3. Connect wire from terminal 21 in master to terminal 12 (point H) in slave unit.

4. Connect wire from terminal 22 in master to terminal 13 (point G) in slave unit.

5. Install relay (TD-100282) in relay base.

Standard Heater Operation

OPERATING PROCEDURE

1. Thermostat must be wired into heater con-

trol 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.

6. Heater should now be lit. If not check to see

that all gas is on.

7. Set thermostat to desired setting (see de-

luxe thermostat manual for adjusting deluxe

thermostat control).

8. Gas pressure should be adjusted so burner

is on 75 per cent of the time.

9. Watch as burner goes through a few cycles,

to be sure that it is operating properly.

Hi-lo Heater Operation

3. Start fan. This will supply power to heater.

4. Turn thermostat dial to its highest setting.

5. Turn toggle switch on.

6. After 20 seconds both red lights should light up

indicating power to the control circuit.

7. Heater should now be lit. If not, check to see

that all gas is on.

8. Open low-fire ball valve all the way.

9. Turn thermostat dial back slowly until heater

cycles to low flame.

10. Adjust ball valve so that low flame pressure is

at desired setting.

11. Turn thermostat dial to desired editing and wait

for bin plenum to come up to temperature.

Heater should cycle to low flame after a few

minutes. If heater does not cycle to low flame

increase hi-flame gas pressure.

1. Thermostat must be wired into heater control

box for heater to operate.

2. Open all manual shut-off valves to heater unit.

12. Low-flame should be adjusted so that tempera-

ture drops slowly until burner goes back to

high flame.

13. Watch as burner goes through a few cycles, to

be sure that it is operating properly.

OPERATING PROCEDURE

Modulating Valve Operation

Deluxe Centrifugal Heater

1. The modulating valve regulates gas flow through the heater based 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 regulator 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 and heater on. To set the modulating valve, turn the T-handle out (counterclockwise) until loose and wait a few minutes 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 plenumtemperature to equalize until the desired temperature is the stable temperature of the ple num. If temperature under bin is the same 10 minutes 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 degrees 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 heater. 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 insures 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 gas pressure will be less. Since 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.

OPERATING PROCEDURE

Adjusting The Vaporizor

1. Vaporizer should be adjusted so

the vapor pipe train runs warm

to the touch (100°-120°F).

2. Loosen 5/16" bolts on adjust-

ment bracket.

3. Raise vaporizer if running too

hot, lower if too cold.

4. Move vaporizer only 1" at a time

and allow a few minutes for tem-

perature to equalize.

5. Tighten 5/16" bolts and watch

heater run for several minutes

to verify adjustment.
