Maintenance
Do Not Use This
Control in an
Application that is
Not Within the Ratings Listed in This
Section. Improper Control Operation
May Result.
Most codes and standards require additional
safeguards and features for oil burner inputs
above 19.9 gph. Consult the appliance
manufacturer’s instructions for control
selection.
Do Not Use This
Control Above 19.9
GPH
Please read and understand the manual supplied
with this control. This control must be installed,
adjusted and put into operation only by a qualifi ed

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 Oil-Burning Equipment, NFPA 31
(or CSA-B139 and CSA-B140 in Canada).

Professional
Service Required
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.
