Current legislation insists that burners are set up using Combustion Testing
Equipment.
In order to obtain the best performance from the burner and cooker these units must
also be set up using testing equipment.

As there is no ideal testing point in or on the cooker it is necessary to do this in the flue above
the

Flue Box. Therefore drill a hole in the flue suitable for the test probe. Before firing the burner

to

test the combustion put a plug in the vent hole in the top oven.  This is to ensure that there is
no flue gas dilution due to air getting in, as this would upset any readings and give false

results. Which could lead to bad combustion as the cooker gets hot.

Start the burner.. After the burner has fired allow approximately 10 minutes for it to settle
down. Then check the combustion.  It should approximately read as follows:

COLD COMBUSTION FIGURES
With the cover plate in position
Co ---   --   --  -- 30 – 100 ppm

CO

2

  --  -- -- -- - 8.8 – 9.0%  This will change when hot

Co/CO

2

 --  -- --  0.0003 – 0.0008

It may be necessary to adjust the combustion to these figures by setting the air lever as
detailed above.

When the cooker is hot and up to temperature this should give:

HOT COMBUSTION FIGURES

With the cover plate in position
Co ---   --   --  -- 30 – 100 ppm

Co/CO

2

 --  -- --  0.0003 – 0.0008

If not it may be necessary to adjust accordingly.

After Setting the combustion REMEMBER TO REMOVE THE PLUG FROM THE OVEN
VENT or you will get condensation coming from the oven, also ensure that the
combustion test hole in the flue is closed.

Remember to leave the customer with the test results.

Servicing.

The annual service consists of the following

(a)  Remove  burner  and  visually  check  baffles/  ceramics.  Repair  ceramics  if  required

with ceramic material (we can supply) ,replace any too badly damaged.

(b)  Clean out burner blast area, removing any debris that may have fallen in.
(c)  Remove nozzle and replace with new. Check and replace blast tube if any cracking at

end .

(d) Remove fan unit and make sure the fan is clean – removing any build up on the blades

and  around the air intake.
