Model 7505
Advanced Burner Control
Description / Applications
The Beckett GeniSysTM Advanced Burner Control is a 120 Vac primary safety control for residential and light commercial oil burners used in boiler, furnace, and water heater applications having firing rates less than 20 GPH. The GeniSys is used with a suitable cad cell flame sensor to control the oil burner motor, igniter, and optional solenoid valve. It has 24 Vac thermostat terminals (if applicable) compatible with bothmechanicalandmanypowerstealingthermostats. Itcanprovideinterruptedor intermittent duty ignition, and it has a 30 second lockout time on recycle.

Installation/Operation/
Maintenance
Professional Service Required
Incorrect installation or misuse of this control could result in severe personal injury, death, or sub-
stantial property damage from heavy smoke, explosion or fire.
Please read and understand the manual supplied with this control. This control must be installed, adjusted and put into operation only by a qualified individual or service agency that is:
Licensed or certified to install and provide technical service to oil heating systems.
Experienced with all applicable codes, standards and ordinances.
Responsible for the correct installation and commission of this equipment.
Skilled in the adjustment of oil burners using combustion test instruments.
The installation must strictly comply with all applicable codes, authorities having jurisdiction and the latest revision of the National Fire Protection Association Standard for the Installation of OilBurning Equipment, NFPA31 (or CSA-B139 and CSA-B140 in Canada).
Regulation by these authorities take precedence over the general instructions provided in this installation manual.
Frozen Plumbing and
Water Damage Hazard
If the residence is unattended in severely cold weather, burner primary control safety lockout, heating system component failures, power outages or other electrical system failures could result in frozen plumbing and water damage
in a matter of hours. For protection, take preventive actions such as having a security system installed that operates during power outages, senses low temperature and initiates an effective action. Consult with your heating contractor or a home security agency.
