HEATER OPERATION
Deluxe Vane Axial Heater
Adjusting the
Vaporizor
1. Vaporizer should be adjusted
so the vapor pipetrain runs
warm to the touch (100°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 minutes
for temperature to equalize.
5. Tighten 5/16" bolt and watch
heater run for several minutes
to verify adjustment.
Adjusting the vaporizer coil on a liquid propane model. The top photo
shows the setting in, and the bottom photo shows the coil out.

LTD HEATER OPERA-
TION
Modulating Valve Operation
Your LTD heater is equipped with a modulating
valve. The following material should be read
thoroughly.
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 reading side 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. T o 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. W ait
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 minutes
after you last made any adjustments to the Thandle you can be certain that the temperature
under the bin is the SET POINT of the valve
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.
6. The modulating valve may require minor adjustment periodically if a certain temperature rise
over ambient (outside) temperature is desired.
7. 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. This is preferred to cycling the application of heat as is commonly done. The grain is not shocked
and cooled quickly and then reheated,
which is a waste of fuel in conventional bin drying systems.
