HEATER INSTALLATION
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.
Be sure fuel supply system complies with all local codes
for L. P. gas installations. DO NOT USE FLAME FOR
LEAK TESTING.

Liquid Propane Models
1. LP models are designed to run on liquid propane, with liquid draw from the propane tank.
A void 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, the usual precaution is to purge the system
with methanol.
2. Run proper size line (see specifications on page
14) to liquid pipe train 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 connections for leaks with liquid detergent or comparable. Wear rubber gloves and eye protection.
Avoid contact with liquid propane. DO NOT
USE FLAME FOR LEAK TESTING.
2. Run proper size line (see specifications on page
14) 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. DO NOT USE FLAME FOR
LEAK TESTING.
Natural Gas Models
1. Natural gas models are similar to vapor mod-
els, but have a larger orifice to accommodate
lower pressure sometimes found with natural gas.
2. Run proper size line (see specifications on page
14) to pipetrain on heater . Have a qualified gas
service man inspect installation to be sure everything is installed according to local codes and
ordinances.
Propane Vapor Models
1. Propane vapor models are designed to run directly off of supply tank or from a separate external vaporizer.

3. After installation is complete check all connections for leaks. DO NOT USE FLAME FOR
LEAK TESTING.

HEATER INSTALLATION
Plenum Thermostat
Mounting
The plenum thermostat is the 4 x
4 white box with knob that is
preconnected to heater when
heater is ordered with thermostat.
1. 24" to the right side of the
transition, drill one 3/8" hole
(high temp) or 1 1/2" hole (low
temp) in the center of the plenum in a valley (4.00" corrugation) or hill (2.66" corrugation) on bin sidewall.
2. Insert the probe through the
hole.

3. Position the housing so that
the tabs are vertical, and the
cord exits the housing horizontally.
1. Mark location on transition
one (1) 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 hi-limit using supplied self drilling
screws.
4. Use 4 self drilling screws to

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 slae 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.
