5. Installation
WARNING
Do not use propane tanks which have previously been used for ammonia unless
they have been purged according to procedures of the national LP association.
Investigate to be sure that the fuel supply system complies with all local codes for
LP gas installations.
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.
Fuel Connection
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 use for vapor draw for long pe riods of time. When u sing 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, the usual precaution is to purge the system with methanol.
2. Run proper size line
service person inspect installation to be sure everything is installed accordin g to loc al cod e s
and ordinances.
3. After installation is complete check all connections for leaks. Use liquid detergent or comparable
substance. Wear rubber gloves and eye protection. Avoid contact with liquid propane. DO NOT USE
FLAME FOR LEAK TESTING.
(See Specifications on Page 12)
to pipe train on heater. Have a qualified gas
Propane Vapor Models
1. Propane vapor models are designed to run directly off of supply tank or from a separate
external vaporizer.
2. Run proper size line
service person inspect installation to be sure everything is installed accordin g to loc al cod e s
and ordinances.
3. After installation is complete check all connections for leaks.

to pipe train on heater. Have a qualified gas
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 on Page 12) to pipe train on heater. Have a qualified gas
service person inspect installation to be sure everything is installed according to local codes
and ordinances.
3. After installation is complete check all connections for leaks.

WARNING
Always disconnect and lock out power before working on or around heater.
CSA Heater Electrical Installation
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.
IMPORTANT: Heater must be interlocked with fan for safe operation.
Heater Power Connection
1. Connect power cord to fan control box.
2. Make field connections in fan box as shown in Figure 5A.
3. Connect deluxe thermostat control as shown in Figure 5A.

5. Installation
Standard Heater - Second Heater Installation
Two (2) standard heaters may be connected to one grain drying system and wired so they cycle tog ether.
One of the heaters should have a thermostat connected to it as per the installation instructions. That
heater will be referred to as the primary. The other heater (without the thermostat) will be referred to as
the secondary.
1. Install relay base (TD-100283) in primary heater control box.
2. Connect wire between terminal 13 on relay base to terminal 5 on terminal strip in primary heater.
3. Connect wire between terminal 14 on relay base to terminal 6 on terminal strip in primary heater.
4. Run two (2) wires (18 gauge) between primary and secondary heater.
5. Connect wires to terminals 5 and 9 (points A and B) on relay base in primary heater.
6. Connect wire from terminal 9 in primary to (point F) in secondary unit.
7. Connect wire from terminal 5 in primary to (point G) in secondary unit.
8. Install relay (TD-100282) in relay base.
Follow these additional steps for HIGH-LOW units.
1. Install relay base (TD-100283) in master heater control box.
2. Connect wire between terminal 13 on relay base to green wire from HIGH-LOW thermostat in master
unit. Do not disconnect other wires from green wire 3. Connect wire between terminal 14 on relay
base to terminal 14 on other relay base in master heater.
3. Run two (2) wires (18 gauge) between master and slave heater.
4. Connect wires to terminals 5 and 9 (points A and B) on relay base in master heater.
5. Connect wire from terminal 9 in master to terminal 6 (point G) in slave unit.
6. Connect wire from terminal 5 in master to cycle solenoid and red light in slave unit. Do not connect
wire to side of cycle solenoid and light that are connected to terminal.

Bin Configuration
Figure 5C
IMPORTANT: When mounting two (2) heaters on a bin it is imperative that they be situated as shown in
Figure 5C. Plenum thermostat must be to the right of master heater and master heater must
1. Mark location on transition one foot up from the bottom (entrance collar) and centered in
the transition.
2. Drill or knock out 7/8" diameter hole on marked location.
3. Install transition high-limit using supplied self-drilling screws.

5. Installation
CAUTION
Thermostat must be installed to operate as plenum high-limit safety.
Plenum Thermostat Mounting
The plenum thermostat must be ordered separately from the heater unit.
1. Follow installation instructions provided with the thermostat assembly.
2. Position the housing so that the bolt flanges are vertical and the cord exits the housing from the
bottom. Mark position.
3. Use 6 (4.00") or 8 (2.66") self-drilling screws to mount the housing to the bin sidewall. DO NOT
TIGHTEN COMPLETELY. Insert corrugation seal into gap between housing and sidewall.
Tighten screws.
4. Caulk between the housing and the sidewall to seal.
Heater control device (thermostat or humidistat) is required for heater warranty on all heaters.

5. Installation
Make sure the configuration matches the appropriate application in the
Fuel - Temperature T abl e above. Propane ha s a higher BTU conte nt than natural gas.
Do not remove 3/8" secondary orifice. Excessive heat rise due to improper orifice
sizing or removing the 3/8" secondary orifice will damage grain or cause fire.
Heater Orifice Setup
The factory has set the orifices size for propane, high temperature and natural gas, low temperature.
1. Determine the type of gas to be used: Propane or natural gas.
2. Determine the operating temperature ranges to be used: High or low. Refer to tables on Page 22
and Page 23.
3. For natural gas high temperature applications remove reducer bushing with pressure gauge and
remove primary orifice from system. Replace reducer bushing and check connections for leaks.
For natural gas high temperature configuration there is no primary orifice in the system. Refer to
Fuel - Temperature Table below.
4. For propane low temperature applications remove reducer bushing with pressure gauge and replace
the supplied primary orifice with orifice supplied in control box. Replace reducer bushing and check
connections for leaks. Refer to Fuel - Temperature Table below.

(Approximate)
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.
