2.4 

INSTALLATION OF THE BURNER 

Also refer to the burner manufacturer’s instructions. 

1.  Position the mounting 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. 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 burners 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. 

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 

This unit may be installed with or without a draft regulator. 
However, 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.
