− LP in accordance with national regulations with a content
of elementary sulphur < 1.5 ppm and volatile sulphur < 50
ppm.
− Ultra Low Sulphur Diesel in accordance with national regu-
lations with a content of elementary sulphur < 15 ppm (for

− Heating oil type 2 when boiler return temperature is not
lower than 140 °F; non-condensing operation. See the
warranty statement for additional details.
− A variety of alternate fuels such as biodiesel, jet fuel A, etc
may also be utilized. Contact
R for applicability.

Do not use gasoline, crankcase drainings, or any oil contain-
ing gasoline.
− The boiler must only be operated with the specied fuels.
− Only burners that are suitable for the specied fuels may
be used.
− Observe the manufacturer's burner selection list and the

1.11 Burners
Follow the burner manufacturer’s instructions when tting the
burner. A pre-drilled burner plate is included with the boiler.
An adapter plate may be required if a non-standard burner is
used (see table).
As standard, the burner plate gasket must be trimmed in order to
t the burner blast tube.
The installer must cut the hole 3/8" larger than the blast tube di-
ameter.
The combustion chamber door must be opened to allow the
burner to be mounted.
If the burner head is too long to open/close the combustion
chamber door, the burner will have to be removed prior to the
opening/closing of the door.
For reduction of burner capacity according to altitude make refer-
