Roof Damage Warning and Disclaimer
The manufacturer does not warrant any roof damage caused by excessive vacuum or internal
pressure from fans or other air moving systems. Adequate ventilation and/or “makeup air” devices
should be provided for all powered air handling systems. The manufacturer does n ot recommend
the use of downward flow systems (suction). Severe roof damage can result fro m any blockage of
air passages. Running fans during high humidity/cold weather conditions can cause air exhaust
or intake ports to freeze.
CAUTION
Excessive vacuum (or pressure) may
damage roof. Use positive aeration
system. Make sure all roof vents are
open and unobstructed. Start roof
fans when supply fans are started.
Do not operate when conditions exist
that may cause roof vent icing.

5. Installation
Always disconnect and lock out power before working on or around heater.
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
Fuel Connection
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.
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.
PNEG-1776 Deluxe Downwind Heater - Canadian 13
5. Installation
Propane Vapor Models
1. Propane vapor models are designed to run directly off of a supply tank or from a separate
external vaporizer.
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 that 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 designed to run directly off of a supply tank or from a separate
external vaporizer.
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. DO NOT USE FLAME FOR
LEAK TESTING.

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.

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.
