ABSTRACT:
A heating-ventilating system including an air duct adapted to be installed in an exterior wall of a poultry house and having a fan mounted near the interior end of the duct and a fuel burner mounted in the duct upstream from said fan, the fuel burner being adapted to burn fuel efficiently in the high velocity air flow provided by the fan; an automatic damper upstream of the burner controlled by the pressure differential across the burner; an igniter including an electric spark generator and a starter-maintainer jet forward thereof for igniting the burner in response to an electrical signal; a controller for the fan which operates the fan alone in response to a warmer than desired temperature in the poultry house, which causes the fan to turn off at a desired temperature range in the poultry house, and which causes the fan to operate in conjunction with the fuel burner for lower than desired temperatures; and a curtain opening controller for automatic adjustment of curtains responsive to the fan burner controller.
