CCAATTAALLYYSSTT
It is recommended that the catalyst is inspected for signs of damage and dirt during routine servicing proce-
dures.
The expected life of the catalyst is in excess of 11,000 hours (10 years of normal use). After this time the cata-
lyst should be replaced.
If there are any deposits of dirt or soot on the catalyst they should be cleaned with a soft brush and a vacuum
cleaner. If removed for cleaning ensure the seals are in good condition before replacing the catalyst. New
seals will usually be required.
The performance of the catalyst may be checked using a Carbon Monoxide (CO) analyser as follows. Position
gas sample probe directly over the catalyst via the lower outlet louvre, in the centre of the upper firebox.
Ignite the fire as per the operating instructions, and run at Maximum setting for 15 minutes. The Carbon
Monoxide (CO) concentration of the gases emmited by the Catalytic Converter should not exceed 15 p.p.m.
(0.0015%).

If replacing the catalyst, remove the hood and front fret, the glass panel. The catalyst is located behind the top
front panel (6 screws), remove these screws and the top panel. Withdraw the catalyst and its seals from the
firebox and discard.
Refit a new catalyst and seals in reverse order.

Appliances that are several years old or have been extensively dismantled should be checked for soundness. It
is important that all the products of combustion pass through the catalytic converter at the top of the firebox
before leaving the appliance.
The firebox is heated by lighting for a few minutes to provide a flow through the firebox and catalytic convert-
er. The burner is then shut off and a smoke pellet or match introduced at the base of the fire underneath the
burner tray. Large quantities of smoke will emerge from the top of the appliance but none should emerge from
around the door. It is important to note that the appliance can never be expected to be 100% smoke tight and
small quantities of smoke may be seen in corners of joints and mating faces etc without affecting safety when
the fire is actually in operation.
