5. OIL BURNER INSTALLATION
WARNING
This combustion equipment must be installed by
qualified service person who is responsible for the
correct installation and adjustment of this equipment.
Failure to comply with this may cause a condition
which may cause severe personal injury, death, or
major property damage.
DANGER
This appliance is intended for use with Commercial
Standard #2 Oil fuel as specified in ASTM D396. Use
with other fuels, including gasoline and crankcase
oil, will void the appliance warranty.
A. GENERAL
1. The oil burner for this appliance is supplied separately
but must be as specified for this equipment. At the
time of this printing, the following burners are Listed
in accordance with UL-726, Oil Fired Boiler
Assemblies:
a) Beckett AFG
b) Heat Wise Pioneer I (Not Yet Available)
2. Check for concealed damage to the burner or controls
when it is unpacked. If concealed damage is found,
notify the carrier and/or wholesale distributor at once.
3. Install the burner in accordance with instructions given
in this section and with those provided by the burner
manufacturer.

3. Care must be taken when routing the oil lines so they
do not interfere with opening and closing the
combustion chamber cover plate. Flexible oil lines
may be installed to allow opening the cover plate for
servicing.
NOTICE
Since the burner on this appliance is located at the
top of the appliance in a down-fired configuration,
disconnecting the oil lines while the burner door is
closed will allow oil to drip into the combustion
chamber. To avoid this, install the burner with flexible
oil lines and only disconnect the lines after the
combustion chamber cover plate is swung open.
4. Oil Burner Specifications: The following charts
indicate the nozzle specification, fuel pressure and
initial air settings for firing the burner. Final
adjustments shall be made using combustion analysis
equipment and a smoke spot tester.
