Air Controls
Keep air controls and inlets/outlets clean and free from ash or debris at all times. Keep
ventilator air inlet grille (if fitted) clean and clear at all times.
Do not leave air controls fully open unless monitoring the fire as over firing damage (typically
bucking of components) can result which is not covered by any warranty.
7.4.1
Air Control Operation
Primary (under grate) air is controlled by the spinner on the lower part of the door. Secondary
(air wash) air is controlled by the slider above the door. Tertiary air is controlled by draught
through pre-set intakes at the back of the stove body. The open position for the Primary air
spinner should only be used for smokeless fuel operations, it is not necessary at all for wood
burning. The closed position of the air wash control should only be used if absolutely necessary
for very slow burning and when burning wood will cause the glass to become blackened, the
chimney to gradually become tarred and smoke to be emitted from the stove.
Wood burning: Move the air wash slider fully to the right (open) for maximum air to start or
revive a wood fire. Returning the lever towards the centre position will reduce the air supply
progressively to reduce the burn rate. The nominal burn rate is usually achieved when the stove
is fully warmed up (2-3 loads of logs) and burning dry hardwood logs by having the lever very
approximately 10mm from the closed position. This is only a rough guide as flue and fuel
conditions will vary the required position. The fire will automatically be supplied with the
correct mix of tertiary air for complete combustion. The maximum position conveniently
provides a boost of primary air as well to get new fuel burning quickly in order to minimise
smoke. Do not leave on maximum setting unless monitoring the fire to ensure over firing
damage does not occur. NOTE: It is not necessary to open the primary air at all once the stove
is warmed up when burning wood unless the flue draught or wood moisture are out of
specification. Doing so may over fire the stove.
Smokeless coal fuel burning: Move the air wash control slider fully to the right side and open
the primary air spinner on the door fully for starting or reviving a coal fire. Returning the air
wash lever towards the closed position will reduce the air supply progressively and improve the
efficiency for burning smokeless fuels as the fire warms up. Also reduce the primary air control
if required to regulate heat output. Do not leave on maximum setting unless monitoring the fire
to ensure over firing damage does not occur NOTE: It is not necessary to open the secondary
air slider more than 3-4mm once the stove is warmed up when burning smokeless coals.
Doing so will keep the glass slightly cleaner but will reduce thermal efficiency.
7.4.2
Air Wash
All Charlton & Jenrick stoves are provided with a sophisticated “air wash” system to assist in
keeping the fire as visible as possible and reducing (not eliminating) cleaning intervals. This
secondary air supply to the stove is controlled through the slider knob above the door. The
Clean Air Act air restrictor bracket will deliberately prevent full closure of this control on the
Wood side of operation. To fix the control in a particular positon it can be screwed down until
tight. Slacken slightly until free enough to move when adjustment is required. The screw cannot
come off the end of its thread but leaving it too slack can lead to air going around the slider
with reduced effectiveness - so maintain it just loose enough to slide smoothly.
7.4.3
Tertiary Air
This appliance is also fitted with a patented tertiary air combustion system that burns otherwise
uncombusted gasses in the products of combustion thereby improving efficiency, increasing
heat output and decreasing unwanted atmospheric emissions. The Tertiary air supply to the
