9.  OPERATION

 

After installing and completion of pilot start up and tests 

SP-48-

NG/PG-

FD

 is ready for operation.  

General description of activities performed by the burner/boiler control system or manually by operator:

 

9.1   Preparation of the furnace/boiler for firing up.

 

9.2   Opening of air to the burner and pilot.

 

9.3   Preparation of gas installation for operation.

 

9.4   Setting the gas pressure at the correct level.

 

9.5   Starting of pilot trial for ignition sequence performed by the controller or in some cases by the operator:

 

a) 

The correct setting of the main burner combustion air. 

b)   Checking the interlock conditions before firing up.

 

c)   Providing power to the ignition source.

 

d)   Optionally, carrying out the gas line leakage test.

 

e)   Closing the purge valves and opening of gas shut off valves.

 

f)  

The  ignition should take  place  within the  time  specified by  the  standards, which  should be  confirmed  
by the relay output of the flame detector.

 

g)    Electrical  igniter  power  off  after  confirming  the  presence  of  the  pilot  flame,  closing  the pilot shut off 

valves (in case of continuous pilot operation they stay open).

 

h) 

In case of the absence of the flame after trial for ignition - the valves are closed and electrical igniter is 
switched off.

 

i)  

Eventual  repeating  of  trial  for  ignition  sequence  (depends  on  the  application).  Details  of  sequence, 
timings are dependent on application and applicable standards.

 

In the case of a  manually controlled gas pilot, the operator has to close the gas supply to the pilot  himself at  the 
right time if the flame is not detected. 

 

 

10.  SERVICE, MAINTENANCE AND REPAIRS

 

To remove the igniter for inspection or repair the gas and electrical supply must be shut off first. Checks that the gas 
and air manual shut off valves are closed and that the power for ignition device is disconnected.

 

 

WARNING

:

      DO  NOT  PERFORM  ANY  MODIFICATIONS  TO  THIS  EQUIPMENT 

AND NEVER USE UNAUTHORIZED SPARE PARTS AS THIS WOULD RESULT IN 
A  BREACH  OF  THE  ATEX  CERTIFICATES  CONDITIONS  AND  COULD  PROVE 
HAZARDOUS TO YOUR HEALTH AND LIFE !

 

 

 

WARNING

:  WHEN  THE  HEATER/BOILER  IS  IN  OPERATION,  DURING  SERVICE 

WORKS  ON  BURNER  INSTALLATION  ALWAYS  USE  PROTECTIVE PPE CLOTHING, 
GLOVES AND GOGGLES !

 

 

 

REMARK

:  EVERY 12  MONTHS MAKE  AN  INSPECTION  OF  AIR TUBE. IF YOU SEE 

ANY TRACES OF EXCESSIVE TEMPERATURE DURING OPERATION INCREASE THE 
COOLING-COMBUSTION AIR FLOW OR RETRACT THE GAS PILOT A LITTLE FROM 
THE COMBUSTION CHAMBER. IF INCREASING THE AMOUNT OF AIR REMEMBER 
THAT IT MAY IMPACT THE FLAME QUALITY.
