HANDING OVER OF THE INSTALLATION

172 305 17  07-01

 

Make repeated start attempts to 

ensure that the adjustments 

function. 

 

Close the ball valve during 
operation to check that the gas 
switch switches off at the set 
value. 

 

Remove the hose for the air 
pressure switch to check that 
the burner locks out. 

 

Check that all protective covers 
and measurement nipples are 
mounted and fastened. 

 

Fill out necessary test reports. 

 

Instruct the persons in charge 
of the operation on the service 
and maintenance of the installa-
tion and what to do should any 
troubles occur. 

 

Inspection and service must 
only be carried out by author-
ized people.

Fault location, functional troubles

Trouble free operation is dependent 

on three factors: electricity, gas and air 

supply. Should there be any changes 
in the ratio between these three factors 
there is a risk of break downs. It has 
been proved that most break downs 
are caused by simple faults. Before 
calling the service engineer, the following 

should therefore be checked:

 

Is the gas cock open? 

 

Are all fuses in order and the 
current switched on? 

 

Are the thermostats correctly 
set? 

 

Are pressostats, overheating 
protection etc. in operating posi-
tion and not locked-out? 

 

Is the gas pressure suficient?

 

 

Is the gas burner control in start 
position? 

 

Has the gas control or the motor 
protector locked out? - Reset. 

 

Is the circulation pump in opera-
tion? 

 

Is there a supply of fresh air to 
the installation? 

If integral components are of a 
different make from what is stated 
in this manual, see the enclosed 
loose-leaf.
