GeniSys® 7590 24V Gas Burner Control
Brand: R.W. Beckett Corporation
The Beckett GeniSys® 7590 Gas Power Burner Control is a safety control designed for use on gas power burners.
This control is intended for use in residential and light commercial gas heating applications.
Applications may include boilers, furnaces, water heaters, space heating and commercial cooking equipment.
The 7590 provides supervision of a separate 120 VAC igniter, a 120 VAC combustion blower motor, a 24 VAC gas valve and 24 VAC connections for an air proving switch (on 7590 C, D).
The control uses flame rectification principles to prove the presence of the burner flame.
Basic diagnostic information is provided through 3 LEDs.
Additional diagnostic information and control setup will be available through the BeckettLink 7700A diagnostic tool.
The Beckett GeniSys® Gas Power Burner Control is a 24 Vac primary safety control designed for use on gas power burners in residential and light commercial gas heating applications.
The GeniSys® Gas Power Burner Control provides supervision of a 120 volt burner motor and a separate 120 Vac igniter as well as a 24 Vac gas valve.
The 7590C and D models provide connections for a combustion air proving switch and monitor the switch position to check for sticking or welded switch contacts.
The standard 7590 is designed for use on applications below 400,000 BTUs. For applications above 400,000 BTUs, contact Beckett’s Engineering Group.
