Abstract: This invention discloses a heating and cooling system for buildings, such as poultry buildings, that provides clean, filtered gas fuel, efficiently burns gas fuel by providing adjustable airflow profile plates that blocks cold air from reaching the inside of the building and creates an air mixture control for the burning flame on the burner, that provides rain gutter means that prevent rain moisture from being drawn into the air stream of the unit and that has an actuating means coupled to the pilot light that assure safe operation by shutting off the gas fuel valves in the event of loss of flame in the pilot.

Abstract: A heating and cooling system for improving the environment in buildings having a large open area, such as poultry buildings, utilizes an electronic ignition to control the temperature and humidity environment. The electronic ignition controls, in a pulsating fashion, the flow of gas feeding a pilot and burner and electrical powwer feeding electro-mechanical relays powering an assortment of blower, circulating fans, as well as a water pump used to distribute water to a water misting cooling arrangement coupled to a main blower and circulating fans to aid in cooling a building. The system includes a set of emergency cooling fans, thermal shut-down switch activates an alarm device to assure a safe and controlled environment in the building.
