5. INSTALLATION
Fuel Connection
Important: Do not use propane tanks which have previously been used for ammonia unless they
have been purged according to procedures of the National L.P. Association.
Investigate to be sure that the fuel supply system complies with all local codes for L.P.
gas installations.
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 (see specification on Page 9) to pipetrain 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.
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 9) to pipetrain 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.
Electrical Connection
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.
1. Connect power cord to fan control box.
2. Make field connections in fan box as shown in Figure 5B.
Important: Heater must be interlocked with fan for safe operation.
3. Connect deluxe thermostat control (optional) as shown in Figure 5B.
Important: Thermostat must be installed for safe operation.
ALWAYS DISCONNECT AND LOCK OUT POWER BEFORE WORKING ON
OR AROUND HEATER

5. INSTALLATION
Standard Heater - Second Heater Installation
Two (2) standard 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 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 6 on terminal strip in
primary heater.
3. Connect wire between terminal 14 on relay base to terminal 3 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 terminal 5 (point F) in secondary unit.
7. Connect wire from terminal 5 in primary to terminal 8 (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 (point E) 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 C and D) on relay base in master heater.
5. Connect wire from terminal 9 in master to terminal 6 (point H) 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.

Heater Operation
1. 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 heater toggle switch to ON.
6. Heater should now be lit. If not, check to see that all gas is on and thermostat is wired in.
7. Watch thermometer on plenum and when it reaches desired temperature turn thermostat
back slowly until heater cycles OFF.
8. Gas pressure should be adjusted so burner is on 75% of the time. (see charts on Page 14)
9. Watch plenum temperature as burner goes through a few cycles to be sure it is operating
properly.

8. HEATER SERVICE
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 lockout power to fan and 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.
ALWAYS DISCONNECT AND LOCK OUT POWER BEFORE WORKING ON
OR AROUND HEATER
