Contact a professional, qualifi ed service agency for the 

installation, adjustment and service of your oil burning 
system.  Thereafter, have your equipment adjusted and 
inspected at least annually to ensure reliable operation. 
This work requires technical training, trade experience,

50 Hz motors — The burner ratings, air settings and nozzle 
ratings are based on standard 60 hz motors (at 3450 rpm). Derate 
all ratings 20% when using 50 hz motors.  Consult factory for 
specifi c application data.

NOTICE

High altitude installations — Accepted industry practice 
requires no derate of burner capacity up to 2,000 feet above 
sea level. For altitudes higher than 2,000 feet, derate burner 
capacity 2% for each 1000 feet above sea level.

NOTICE

Pre-installation checklist

The burner cannot properly burn the fuel if it is not 
supplied with a reliable combustion air source.
Follow the guidelines in the latest editions of the NFPA 
31 and CSA-B139 regarding providing adequate air for 
combustion and ventilation.

For appliance/burner units in confi ned spaces, the room 
must have an air opening near the top of the room plus 
one near the fl oor, each with a free area at least one square 
inch per 1,000 Btu/hr input of all fuel burning equipment 
in the room. For other conditions, refer to NFPA 31 (CSA 
B1139-M91 in Canada).

If there is a risk of the space being under negative pressure 
or of exhaust fans or other devices depleting available 
air for combustion and ventilation, the appliance/burner 
should be installed in an isolated room provided with 
outside combustion air.

 Clearances

With the burner installed in the appliance, there must be 
adequate space in front of and on the sides of the burner 
to allow access and operation. Verify that the clearance 
dimensions comply with all local codes and with the 
appliance manufacturer’s recommendations.
