INSTALLATION OF THE BURNER
Also refer to the burner manufacturer's instructions.
1.
Position the gasket between the mounting flange and the burner
mounting plate. Align the holes in the burner mounting plate with
the studs on the mounting flange and bolt securely in place.
2.
Remove the burner drawer assembly or the air tube assembly;
3.
Install the nozzle (refer to Technical Specifications, p.13);
4.
Check the electrode settings;
5.
Make the electrical connections;
6.
Complete oil line connections.
2.4.1
Nozzles
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 marking.
2.4.2
Air and Turbulator Settings
Before starting the burner for the first time, adjust the air and
turbulator settings to those listed in this manual, Table 6. Once
the burner becomes operational, final adjustments will be
required. Refer to section 3 of this manual.
2.4.3
Post 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
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.
2.5.1
Masonry 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.
Before venting this furnace into a chimney, its condition must be
checked and repairs made, if necessary. Also, the chimney lining
and dimensions must conform to local and national codes.
2.5.2
Factory Built Chimneys
Oil fired furnaces are approved for use with "L" type vents. The
unit may also be used with an approved chimney of proper
dimensions and temperature ratings as specified in the
installation code. Refer to chimney manufacturer's instructions
for proper installation.
2.5.3
Draft Regulator
It is recommended that a draft regulator be installed in cases
where the draft is either high or variable due to external
conditions. Follow the instructions provided with the regulator.
2.5.4
Side-Wall Venting
The heating unit is approved for side-wall venting. This system is
comprised of a model VTK-54 / VTK-098 / KLAVT0101DET side-
wall venter and a 4" insulated vent pipe, model IFV-410 / IFV098-
10 / KLAFV0101DET, IFV-420 / IFV098-20 / KLAFV0201DET.
Refer to the installation instructions provided with the venting
system.
