20.0 CATALYSTS
Now divide the concentration of carbon monoxide (CO) expressed in
percent by the concentration of carbon dioxide (CO2) to obtain the
appliance combustion ratio.
CO (%)
CO2 (%) = ratio
The combustion ratio of the gasses emitted by the catalytic convertor
should not exceed 0.0015.
If replacing, firstly, remove the decorative fire frame as described in
section 15.0. The catalysts are located on the top of the internal firebox
and can be removed be unscrewing the retaining nuts securing the
clamping plate. Remove the catalysts and the seals and discard.
Refit a new catalyst and seals in reverse order, ensure the catalyst and
door have a good seals.

21.0 TESTING FOR FIREBOX LEAKAGE

Appliances that are several years old or have been extensively disman-
tled should be checked for soundness. It is important that all the prod-
ucts of combustion pass through the catalytic convertors 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. 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 the joints or gasket faces, especially around
the door. It is important to note that the appliance can never be expect-
ed to be 100% smoke tight and small quantities of smoke may be seen
in corners of joints and gasket faces etc without affecting safety when
the fire is in operation.

22.0 CLEANING

WARNING: TURN OFF THE UNVENTED GAS ROOM
HEATER AND ALLOW TO COOL BEFORE CLEANING.
GLASS PANEL -This can be cleaned with a suitable glass cleaner, or
proprietary ceramic hob cleaner. Test on a small area first.
PAINTED AREAS - These can be cleaned using a dry cloth.
STAINLESS STEEL AREAS - These can either be cleaned using a
proprietary stainless steel metal cleaner or baby oil. Test on a small hid-
den part of the stainless steel before cleaning. Always clean in the
direction of the grain.
