Flue Gas Analysers – Installation & Servicing Facts
•
Please read this sheet even if you have fitted our fires before.
•
Please leave this sheet with the customer as reference for future servicing of the appliance.
•
Please explain to the customer how the fire works and the details and facts listed on this
sheet, particularly what the catalyst does and doesn’t do.
•
If you have any doubts about the test procedure please visit our website or call our technical

Testing – Points to note…
•
Before testing ensure that the room size is correct for the heat output of the fire. 30cu³ for
2.5kw output, 40cu³ for 3.5kw and 50cu³ for 4.5kw.
•
In all installations regardless of room size there must be an air vent positioned at least one
metre from the fire at either high or low level through an outside wall providing 100cm² of
free air. (For the Republic of Ireland 2 vents of not less than 60cm² must be provided at high
and low level, with minimum vertical separation of 1.6m).
•
The analyser used must be manufactured to BS7967 and the test must be carried out in
accordance with BS5871 Pt 4
•
The catalytic converter needs heat to work, therefore before you start testing; the fire must
have been lit and burning on full for at least 15 mins.
There are two tests to carry out. A Co / CO² ratio test and a room centre CO test.
1.
The first test is the CO / CO² ratio test and should be carried out at the fire exhaust vent, do
not stick the probe of the analyser in through the grill but move the probe back and forth 1
inch in front of the outlet grill. (We use a piece of perforated 8mm pipe attached to the
analyser with flexible rubber tube). You should record a ratio of no more than 0.002 %
(20ppm CO to 1% Co²). It is advisable to have a high sample of CO as this will improve the
test
2.
The second test is the room centre CO test. You should stand in the room centre with the
probe at waist height and read the level of CO; this should be no more than 9ppm over
ambient peak. Please record these readings on the customers guarantee card.
Our Flueless fires also contain the following safety devices (an ODS (Oxygen Depletion Sensor) and
FSD (Flame Supervision Device). Point out to the customer that unfortunately these are not found
on all gas hobs; which are also flueless devices)
