Tertiary Air
This appliance is also fitted with a draught controlled tertiary air system that burns otherwise
uncombusted gasses thereby improving efficiency, increasing heat output and decreasing
unwanted emissions. The Tertiary air supply to the stove is controlled automatically by the
draught in the flue and firebox. At certain stages of burning you will notice “jets” of flame
emerging near the air holes to the rear of the firebox. This is not always visible depending upon
the fuels used and burn cycle stage so there is nothing untoward if it cannot be seen.
6.4.
Multifuel Grate
Your stove is fitted with a multifuel grate. A build up of wood ash when burning wood will not
harm the grate and indeed wood is said to burn well on a bed of ash but excessive wood ash
build up is not recommended. Smokeless fuel ash must be regularly removed and NOT allowed
to build up under the grate.
The tab lever with a hole in it just below the main glass window controls the primary air supply
to the under grate area for burning briquetted smokeless fuels only. The primary air supply will
normally be around 50% open (100% open for 8kW version) for nominal output at average flue
draughts but will vary from one installation to another.
The primary air control must be closed when burning wood under normal circumstances.
Opening the primary air control too wide can over-fire the stove and permanently damage it if
left in operation. Any such over-firing damage is NOT covered by any warranty.
6.5.
Ashpan
The ash pan assembly has seals around it that must be well maintained for correct burning of
wood with the primary air supply closed. If air leaks that may develop due to seal wear or
damage are not corrected then wood burning may become difficult to control. Check and
maintain the sealing of this area very carefully.
It is essential that you empty the stainless steel ash pan regularly when burning coal type fuels.
Use the flat end of tool to lift the ash pan out of the stove. DO NOT allow coal ash to build up
underneath the bed as this may cause damage to the grate.

Cleaning
Glass: Despite the advanced air wash system provided, the glass will still need cleaning from
time to time depending on the fuel quality and burning rates used. Never clean glass when the
stove is hot. Always use stove glass cleaner or ceramic hob cleaner, which is available from your
stove retailer or supermarket. As an alternative, use a wet cloth with some of the wood ash if
burning wood but be very careful to use very clean ash so as not to scratch the glass. DO NOT
use coal ash to clean the glass.
Outer body: The outer body simply needs to be dusted or wiped with a clean dry cloth from
time to time. DO NOT use wet cloths as it can spread plaster, cement, fire cement or fire board
dust and subsequently cause the paint to turn grey with heat where it has been wiped. DO NOT
use any kind of furniture polish or cleaning agent other than your stove suppliers recommended
paint.
Inner firebox: Brush the inside of the firebox clean from time to time to check the integrity of
the plates and liners etc. See Maintenance Guide section for instructions on how to remove
parts of the stove. It is not normally necessary to paint inside the firebox due to the high
temperatures that mean that the paint does not have much effect before being burnt off. Steel
and ceramic firebox liners are very resilient firebox materials and will give reliable service
without major cleaning or work on the firebox. The ceramic firebox linings may require
replacement occasionally depending upon fuels and the type of usage experienced. Firebox
