1. Safety
General Safety Statement
Our foremost concern is your safety and the safety of others associated with grain handling equipment.
This manual is to help you understand safe operating procedures and some problems which may be
encountered by the operator and other personnel.
As owner and/or operator, you are responsible to know what requirements, hazards and precautions
exist and inform all personnel associated with the equipment or in the area. Safety precautions may be
required from the personnel. Avoid any alterations to the equipment, which may produce a very
dangerous situation, where serious injury or death may occur.
This heater is designed and approved for use as an Agricultural Animal Confinement Building
Heater under AGA Requirement LC-2. The intended use of the heater is to heat well-ventilated
animal confinement buildings.
The products of combustion created by these heaters (i.e. carbon dioxide, nitrogen dioxide, carbon
monoxide) are released into the airstream being heated. To properly dilute the combustion products of
heater installations which recirculate insideair, at least 4 CFM of fresh air per 1000BTU’s of the heater’s
rated input are required. Refer to the ventilation requirements found in the Heater Specifications
(See Specifications) of this manual.
Compare the total ventilations requirements of the heating system (Number of recirculating heaters
multiplied by the ventilation requirements of each heater) to the overall ventilation requirements of the
facility. In most animal confinement buildings, the ventilation required to maintain the proper oxygen
content exceeds the ventilation required to properly dilute the combustion products. If the ventilation
requirement of the facility is below the requirement of the heating’s system, increase the facility’s
ventilation or change one or more of the recirculating heaters to the non-recirculating type
(Intake outside air only).

General Safety Information
1. Observe all safety, installation, operation and maintenance instructions before placing this heater
into service.
2. Installation of the heater(s) must comply with all applicable local, state and national codes.
3. This heater is NOT to be used to heat human living quarters.
4. DO NOT use in unventilated areas. Adequate ventilation is essential to safe operation. When
operating this heater, the forming of moisture droplets on cold surfaces or the feeling of nausea or
headaches is an indication of improper ventilation. Prolonged exposure to improperly ventilated
areas can result in asphyxiation or death.
5. DO NOT use this heater in areas where gasoline or other liquids having flammable vapors, or in
heavy dust laden atmospheres (i.e. mills, granaries, etc.). Failure to follow this warning can result
in an explosion.
6. DO NOT attach any inlet and/or discharge duct work other than approved accessories to the
heater. Excessive static pressure may cause this heater to overheat and/or cause excessive
amounts of combustion products to be discharged into the space.
7. Maintain proper clearances to combustible material. See heater nameplate for specific clearance.
8. DO NOT operate this heater with improper fuel. See heater nameplate for fuel specified.
9. DO NOT position fuel cylinder in path of discharge air.
10. This heater will not operate correctly unless the gas supply pressure is properly regulated. Under no
circumstance should the gas pressure supplied to the heater be greater than 14" W.C. (1/2 PSI).
11. All gas high-pressure regulators must be vented to the outside of the building with no reduction in
size of the vent piping. The vent piping should be designed to prevent the entry of water, insects
or other foreign material that could cause blockage.
12. DO NOT connect this heater to the supply gas line unit all piping has been pressure tested and
purged. Damage to the gas valve may result.
13. DO NOT grip gas valve body with pipe wrench or vise. Damage may result causing gas leakage.
Use inlet or outlet bosses or a special body wrench.
14. The air inlet openings are located on the bottom of the heater. DO NOT operate heater while it is
sitting on its base.
15. This appliance is equipped with a three-prong (grounding) plug and should be plugged directly into
a properly grounded three-prong receptacle.
16. DONOTbypass anysafetydevices.Replaceorrepairdefectivecomponentsbeforeplacingheater
into service.
17. Protect the power cord from coming into contact with sharp edges or the base of the heater.
18. DO NOT repair, handle or move unit while hot or operating.
19. Before each use of this heater, an inspection of the heater, power cord, hose assembly (if used),
and gas piping is essential to ensure safe and satisfactory heater operation. This inspection should
be performed by qualified service personnel at least once a year. Use only the factory specified
hose assembly for field replacement. See Parts List.
20. The hose assembly shall be visually inspected on an annual basis. If it is evident that there is
excessive abrasions or wear, or the hose is cut, it must be replaced prior to the heater being put
into operation. The replacement hose assembly shall be that specified be the manufacturer.
