APPENDIX 2

FLOWCHART FOR CO AND COMBUSTION RATIO CHECK ON COMMISSIONING A CONDENSING BOILER

PRIOR TO CO AND COMBUSTION RATIO CHECK

The installation instructions should have been followed, gas type verified and gas supply pressure/rate checked as required prior to commissioning.

As part of the installation process,

ESPECIALLY WHERE A FLUE HAS BEEN FITTED BY PERSONS OTHER THAN THE BOILER INSTALLER

, visually check the integri-

ty of the whole flue system to confirm that all components are correctly asembled, fixed and supported. Check that manufacturer's maximum flue lengths have not

been exceeded and all guidance has been followed (e.g. Gas Safe Technical Bulletin TB008).

The flue gas analyser should be of the correct type, as specified by BS 7967

Prior to its use, the flue gas analyser should have been maintained and calibrated as specified by the manufacturer. The installer must have the relevant competence

for use of the analyser.

Check and zero the analyser IN FRESH AIR as per analyser manufacturer's instructions.

NOTE

the air gas ratio valve is factory-set and must not be adjusted DURING

COMMISSIONING unless this action is recommended after discussions

with SIME LTD.

If any such adjustment is recommended and further checking of the boiler

is required the installer/service engineer must be competent to carry out

this work and to use the flue gas analyser accordingly.

If the boiler requires conversion to operate with a different gas family

(e.g. conversion from natural gas to LPG) separate guidance will be provi-

ded by the boiler manufacturer and must be followed.

SET BOILER TO MAXIMUM RATE

Set the boiler to operate at maximum rate (full load condi-

tion). Allow sufficient time for combustion to stablilise.

NOTE - Do not insert analyser probe during this period

to avoid possible "flooding" of sensor.

CARRY OUT FLUE INTEGRITY CHECK USING ANALYSER

Insert analyser probe into the air inlet test point and allow readings

to stabilise.

NOTE - The flue must always be installed with flue test point.

This will be located within the first piece connected to the boiler.

Is O

less than

or equal to 20.6%

and

less than 0.2%

VERIFY FLUE INTEGRITY

Analyser readings indicate that combustion products and inlet air must be

mixing. Further investigation of the flue is therefore required.

Check that flue components are assembled, fixed and supported as per boi-

ler/flue manufacturer's instructions.

Check that flue and flue terminal are not obstructed.

Is O

less than

or equal to 20.6%

and

less than 0.2%

CHECK CO AND COMBUSTION RATIO AT MAXIMUM RATE

With boiler still set at maximum rate, insert analyser probe into

flue gas samplng point. Allow readings to stablise before recording.

Turn off appliance and call SIME

LTD Technical HelplIne for advice.

the appliance must not be com-

missioned or used, until problems

are identified and resolved.

Is CO less than 350ppm

AND

CO/CO

ratio less than 0.004

Check all seals around the appliance

burner, internal flue seals, door and

case seals. Rectify where necessary.

SET BOILER TO MINIMUM RATE

In accordance with boiler instructions, set boiler to operate at

minimum rate (to minimum load condition). Allow sufficient time for

combustion to stablilise.

NOTE: If manufacturer's instructions do not specify how to set

boiler to minimum rate contact Technical Helpline for advice.

CHECK CO AND COMBUSTION RATIO AT MINIMUM RATE

With boiler set at minimum rate, insert analyser probe into flue gas

samplng point. Allow readings to stablise before recording.

NOTE - if no flue gas sampling point is present and the correct pro-

cedure is not specified in the manual, contact SIME LTD Technical

Helpline for advice.

Is CO less than

350ppm

AND

CO/CO

ratio

less than 0.004

Turn off appliance and call SIME LTD

Technical HelplIne for advice.

the appliance must not be commissio-

ned or used until problems are identi-

fied and resolved.

NOTE

Check and record CO and combustion

ratio at both maximum AND minimum

rate before contacting SIME LTD.

Is CO less than 350ppm

AND

CO/CO

ratio

less than 0.004

BOILER IS OPERATING SATISFACTORILY

no further actions required

Ensure test points are capped, boiler case is correctly repleced and all other commissioning pro-

cedures are completed.

Complete Benchmark Checklist, recording CO and combustion ratio readings as required.
