•Check your oil tank level. Always keep your oil tank full, especially during the summer, in order to pre- vent condensation of moisture on the inside surface of the tank.

!WARNING Do NOT Alter the Original Burner Design

Tampering with or altering the burner design could seriously impair performance, resulting in loss of static pressure, damage to the system components, reduced air volume, heavy smoke, ﬂame impingement, appliance sooting, hot gas puff-back, and asphyxiation or ﬁre hazards.

Maintain the design to its original conﬁguration. Only use parts speciﬁed for AF or AFG Burners

Do NOT remove the air guide from the AFG chassis.

Do NOT use ‘M’ Series air tube combinations on AF Burn- ers.
