Machine to Earth Ground

It is very important that a machine to earth ground rod be installed at the fan. This is true even if there is
a ground at the pole 15' away. This ground needs to be as close to the fan as possible, but no more than
8' away. The ground rod should be connected to the fan contro l panel with at least a # 6 solid bare copper
ground wire, or in accordance with local requirements. The machine to earth ground provides additional
safety if there is a short. It also provides the grounding necessary for long life and operation of the solid
state circuit boards used on control circuits and the electronic ignition systems.

Previously Installed Units

It is recommended that previously installed units be checked to see that a machine to earth ground
has been installed by an electrician.

Standard electrical safety practices and codes should be used when working with a heater. Refer to the
National Electric Code Standard Handbook by the National Fire Protection Association. A qualified
electrician should make all wiring installations.

WARNING

IMPORTANT: Do not use propane tanks that have previously been used for ammonia unless they have

been purged according to procedures of the National LP association.
Fuel supply system must comply with local codes for LP gas installation.

Liquid Propane Models

1. LP models are designed to run on liquid propane 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 moisture that may be present in tank or lines may freeze when system is used in
cold weather. To avoid this situation, purge the system with methanol.

2. Run proper size line (See Specifications on Page 12) to liquid pipe train on heater. Have a qualified
gas service person inspect installation to be sure that everything is installed according to local codes
and ordinances.

7. Service

Seasonal Inspection and Service

All parts are made of weather-proof construction and are designed to require a minimum of service;
however, we recommend the following items be checked and serviced, as described, before the unit is
used each season. Replace any damaged or questionable parts.

THESE CHECKS WILL HELP ELIMINATE POSSIBLE MINOR FAULTS AND ASSURE DEPENDABLE
OPERATION OF THE EQUIPMENT WHEN IT IS NEEDED.

1. Check fan and service it as described within the fan installation and operation manual.

2. Shut off electrical power. Remove heater control box cover and inspect for moisture, rodent damage
or accumulated foreign material remove any foreign material present. INSPECT AND TIGHTEN ALL
LOOSE TERMINAL CONNECTIONS. Replace any damaged or deteriorated wiring.

3. Shut off fuel and remove and clean gas line strainer.

4. Remove the orifice from the burner venturi and inspect for obstructions. Also, inspect and clean out
the burner venturi and the ports within the burner cup. Blow out with compressed air or disassemble
and thoroughly clean these parts. Foreign material in the venturi or burner cup will impair heater
operation and cannot be expected to burn out when the heater is started.

5. Inspect and clean the electrodes on the ignitor plug. Use an ignition point file to remove carbon and
rust between the electrode surfaces.

6. Inspect flame rod and ignitor plug wires for possible damage or poor connections.

7. After completing all checks and performing any necessary service, check the control device, as
described under the following appropriate heading.

Heaters Equipped with a Humidistat Control

Temporarily remove humidistat control from air plenum chamber of bin. Rotate the knob through the 20%
to 80% humidity range. The switch within the humidistat should produce a small “click” when the lever
passes the point of prevailing humidity.

NOTE: For additional information, refer to instructions that accompanied the humidistat.

Heaters Equipped with a Thermostat Control

Slowly rotate the thermostat dial through its temperature range. The switch within the thermostat should
produce a small “click” when the dial passes the point of prevailing temperature. Set the dial to a setting
at least 10°F above the prevailing temperature and proceed to the next step.

8. Test operate the fan and heater. Make sure to follow operating instructions, INCLUDING. After fan
starts operating and the heater purge interval has elapsed (approximately 20 seconds delay), the
heater should come ON and start operating.

9. Slowly change the humidistat or thermostat setting and cycle the heater OFF and ON to make sure
the device is controlling the heater and is operating properly.

7. Service

10. LP MODELS ONLY - After heater has been operating for some time and temperatures have
stabilized, check temperature of the gas line between outlet side of vaporizer and the gas regulator.

If gas line becomes “frosted” with an accumulation o f ice build-u p, adjust vaporize r slightly closer to
the flame. If line reaches a high temperature where it is hot to the touch, adjust vaporizer further away
from the flame.

NOTE: If gas temperature exceeds approximately 220°F, the vapor high-limit thermostat will open

the electrical circuit to the liquid gas solenoid valve and shut off fuel flow to stop the heater.
This condition can be verified by temporarily connecting a jumper wire across the connections
of the high-limit and observing that the burner re-lights. If high-limit vapor thermost at causes
the burner to stop operating, it may also cause the burner to go into a safety lock out
condition. Refer to heater operating instructions for restarting procedure.

11. Vaporizers should be inspected and serviced prior to each season of operation, including
the following:

a. Carefully inspect the surfaces of the vaporizer coil and the inlet and vapor outlet pipes for

evidence of severe corrosion or abrasion of metal which could cause subsequent leakage of
liquid propane, gross overheating and fire hazard.

b. Insecure mounting of either the vaporizer or burner, due to loosened bolts, can cause interference

between burner vanes and vaporizer pipes, with the natural vibration of the unit causing erosion
of the pipe metal at the point of maintained contact.

c. If there has been significant abrasion of the steel vaporizer pipe, it must be replaced.

12. When satisfied that heater is operating properly, make sure to reset the control d evice to the p roper
setting and restore the fan and heater for normal type operation.

IMPORTANT: Use care when troubleshooting this product. Limit exposure to potential hazards by

following all recommended safety practices.

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. 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.

1. 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.
