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 inside air, at least 4 CFM of fresh air per 1000 BTU’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).
