OZZLES
The burner comes equipped with an appropriate nozzle.
However, if another size or a replacement nozzle is
required, use the manufacturer’s recommended spray
angle and type a shown in Table 1 and based on a pump
pressure of 100 psi.
Always select nozzle sizes by working back from the
desired flow rate at operating pressure and not the nozzle

ETTINGS
Before starting the burner for the first time, adjust the air
and turbulator settings to those listed in this manual, Table

manual.
2.4.3
P
OST PURGE DELAY ADJUSTMENT
The post purge delay on the oil-fired burners is factory set
to zero second. This delay is applicable for all installations
with chimney venting. For heating units installed with side
wall venting and a burner equipped with this feature, the
post purge delay must be set to 15 seconds. No delay is
required for Riello burners. Refer to the burner control
instruction manual and markings for proper adjustment of
the post purge delay.
2.5 VENTING
WARNING
Poisonous carbon monoxide gas hazard.
Never install a hand operated damper in the vent pipe.
However, any Underwriters Laboratories listed,
electrically operated automatic type vent damper may
be installed if desired. Be sure to follow the
instructions provided with vent damper. Also, read
and follow all instructions in this section of the
manual.
Failure to properly vent this furnace or other
appliances can result in death, bodily injury and/or
property damage.
To ensure the safe and proper functioning of an oil
furnace, it must always be connected to a flue with
sufficient draft or to an approved side-wall venting system.
In addition, it is strongly recommended to perform a
complete inspection of all the existing venting systems.

ASONRY CHIMNEY
This furnace can be vented into an existing masonry
chimney. However, the unit must not be vented into a
chimney into which a solid fuel burning furnace is already
being vented.
