Enertech Bentone ST 133 K, Installation And Maintenance Instruction

General rules

The installation of an oil burner should 
be carried out in accordance with local 
regulations. The installer of the burner 
must therefore be aware of all regula-
tions relating to oil and combustion.
Only oil suitable for the burner should 
be used and then in combination with 

a suitable oil filter before the oil pump 

of the burner.
If the burner is replacing an existing 

burner make sure that the oil filter is 

replaced or cleaned. The installation 
must only be undertaken by expe-
rienced personnel. Care should be 
taken by the installer to ensure that no 

electrical cables or fuel/gas pipes are 

trapped or damaged during installation 

or service/maintenance.

Installation instructions

General installation instructions ac-
company the burner and should be 
left in a prominent place adjacent to 
the burner.

Adjustment of burner

The burner is from the factory pre-set 
to an average value that must then be 
adjusted to the boiler in question. 
All burner adjustments must be made 
in accordance with boiler manufactu-
rers instructions.These must include 

the checking of flue gas temperatures, 

average water temperature and CO

2

or O

2

 concentration.

To adjust the combustion device, 
start by increasing the air volume 
somewhat.

When the burner starts it is  burning 

with excess air and smoke number 
0. Reduce the air volume until soot 
occurs and increase again to reach 
a combustion free of soot.
By this procedure an optimum adjust-
ment is obtained. If larger nozzles 
are used the preadjustment of the air 
volume must be increased.

Condensation in chimney

A modern burner works with less 
excess air and often also with smal-
ler nozzles than older models. This 

increases the efficiency but also the 

risk of condensation in the chimney. 
The risk increases if the area of the 

chimney flue is too large. The tempe

-

rature of the flue gases should exceed 

60°C measured 0,5 metres from the 
chimney top.

Pump adjustment

See separate description. 

Adjustment of burner

To obtain a correct adjustment a 

flue gas analysis and a temperature 

measurement must be carried out. 
Otherwise there is a risk that a bad 
adjustment may cause a formation of 

soot, bad efficiency or condensate in 

the chimney.

Maintenance

The boiler/burner should be examined 

regularly for any signs of malfunction 
or oil leakage.

GENERAL INSTRUCTIONS

Measures to raise the temperature:
Insulate the chimney in cold attics
Install a tube in the chimney
Install a draught regulator (dilutes the 

flue gases during operation and dries 

them up during standstill)
Increase the oil quantity

Raise  the  flue  gas  temperature  by 

removing turbulators, if any, in the 
boiler.

Instructions for use

The end user of the burner should be 
instructed about the operation and 
safety features of the burner.
He should also be made aware of 
the  importance of the area around 

the  boiler/burner  being  kept  free  of 

combustible material.
