2.4.6 Oil burner
This furnace is supplied with a high pressure atomizing
retention head type burner for use with not heavier than
grade 2 Fuel Oil. If the burner model is a Beckett AFG, the
mounting flange is fixed to the burner air tube and no
adjustment is required for length. If a RielIo burner is used,
refer to the Technical Specifications, Table 5 for the
insertion length.
NEVER use the "interrupted ignition" function if a
Beckett AFG burner is installed on the furnace.
Oil Connections
Complete instructions for installation of the fuel oil piping will
be found in the oil burner installation instructions included
with the furnace.
