OPERATING INSTRUCTIONS

AIR INLET CONTROLS

The AX range of stoves have two air inlet
controls.
The primary air inlet providing under draught to the
base of the fire chamber through the control slider
located under the window of the fire door.
The air wash system, so called because its pre­heated high speed air, washes across the inner
face of the door glass, keeping it clear. This also
provides an over draught to the fuel bed.

PRIMARY AIR

Air enters the appliance through the control on the
bottom of the fire door. The AX 1 & 2 has a single
control knob which slides left to right. Sliding the
knob to the Right, see Fig.6, will increase the
amount of air intake to the stove. To Decrease,
push the slider to the Left as in Fig. 7

AIR WASH SYSTEM

The air wash has an internal sliding plate with
slots, housed in a cover plate, and is located inside
the fire door. Sliding the control knob to the Right
as far as it will go, achieves the fully open position,
see Fig. 8. Sliding it to the Left will shut off the air
inlet slots as shown in Fig. 9.

ANNUAL MAINTENANCE

It is important that your appliance is regularly
serviced in accordance with these instructions.
This should be carried out at least annually by a
qualified person and should consist of the
following :

CLEANING

Important; Under some circumstances soot can

quickly build up on the throat plate and adjacent
areas. The throat plate should be removed and
checked monthly, and any debris stripped off. Sim­ilarly, clean the upper surface of the firebox.

Remove the firebrick linings and throat plate,
inspect all gasketing on doors, glass etc, and
re-order any items that may need replacing from
your AX stove Dealer.
With a wire brush clean inside the appliance
paying particular attention to the small inlet holes
of the air inlets on the inside of the fire door.

Sweep the chimney and confirm that it is sound.
Examine all joints in the flue pipe etc, and re-seal
if necessary. Re-assemble and leave with the air
inlet and air wash control about half way open.
This will allow a free flow of air through the
appliance thus preventing moisture and
condensation from building up inside the stove and
chimney.

CHIMNEY SWEEPING

Sweeping should be carried out with an
appropriate sized bristle brush and rods to suit
chimney size and type. As with all appliances
regular sweeping of the flue is essential to avoid
danger of blockage and the escape of poisonous
fumes. Access for cleaning should also be
incorporated in the chimney (e.g.. Soot door or
access through the register plate).

Any existing chimney should be swept prior to
installation of the appliance, and swept again a
second time within one month of regular use after
installation to establish frequency of sweeping
required. This should be done by a competent
person such as a NACS chimney engineer who will
provide a Certificate Of Chimney Sweeping.
The whole flue way including the outlet must be
swept at least twice per burning season. It is
important that the flue ways, flue pipe and chimney

be cleaned prior to lighting the appliance after a
prolonged shut down period.

DOOR GLASS

The door glass should remain clear during normal
burning. However, under certain conditions, such
as burning at a low rate or damp wood, or over­night burning, the glass may become somewhat
blackened. To remedy this, operate the appliance
at a fast rate. Alternatively when the stove is cold,
open the door and clean the inside face of the
glass with a damp cloth or with glass cleaner
(available from fire stockists). A piece of cloth
moistened with vinegar and dipped in wood ash
(not coal ash) will provide a good soft scourer to
remove the soot without scratching the glass.

OUTER FINISH

The outer finish of the appliance is a durable high
temperature paint. It is best cleaned by brushing
down with a clean shoe brush. Do not allow
moisture to remain on the appliance whilst cold or
surface rust may form.
The high temperature paint should not require
attention for some time, depending on use. The
hotter the fire burns sooner repainting will be
necessary. Aerosol tins of paint are available for
complete refurbishing.
Before repainting make sure that the fire is out and
the stove is cold.

x Remove the door glass
x Lightly wire brush, or rub with wire wool, the

body of the appliance to remove any loose
paint or rust.

x Mask or remove items such as brass work.
x Any adjacent brickwork, mantelpiece, hearth

etc, should be carefully masked for quite a
distance around the appliance. This
precaution is to prevent discolouration of the
surrounding brickwork or wall paper etc.

Re-spray in a well ventilated area, avoid
breathing the vapour. Refer to safety
instructions on paint cans.

x When the paint is dry refit the door glass &

any other parts previously removed.

x Leave the appliance for eight hours before

lighting a fire.

x Burn slowly for the first four hours, then build

up heat slowly to gradually cure paint.

Note: Use genuine Arada touch up spray as some
paints interact. This could ruin the finish and
invalidate the guarantee.

SERVICE & MAINTENANCE

SUMMER STORAGE / NON
USAGE

Please ensure that your stove is left clean and
moving components are well lubricated for the
summer months (during periods of prolonged non
use). If possible store the throat plate outside of the
stove, check all moveable components, at regular
intervals, to ensure they are moving freely.

Allow air movement through the stove, by opening
the air wash and primary air inlet(s) controls to
about half way open or leave the door ajar. This will
allow a free flow of air through the appliance thus
preventing moisture and condensation
forming inside the stove and chimney. This
preventative maintenance will ensure your stove
stays in the best condition for the coming winter
months.

ADJUSTING THE DOOR HINGES

Once the appliance has been under fire for a
period of time the fire door may appear to have
moved out of alignment with relation to the door
aperture or catch. This is quite normal and due to
the settling of the casting.
The fire door can be re-aligned as follows :

x When the appliance is cold, open the fire door

so that it is at right angles to the front of the
stove.

x Lift the fire door up off its hinges.

x Gently tap the hinge pins in the direction to

compensate for the misalignment. (Fig. 11)

x Re-fit the door and check to ensure it now sits

square to the body; if not repeat the above
steps.

If the fire door needs to be raised,

please follow :

x When the appliance is cold, open the fire door

so that it is at right angles to the front of the
stove.

x Lift the fire door up off the hinges.

x Drop one washer on the top and bottom hinge

pins. Fit the door and check.

Please Note :
There is no adjustment to the door lock /
catch assembly.

FUEL RETAINER

A Fuel retainer is supplied with the stove.
Periodically check for any bowing or heat warp
age to the fuel retainer and replace if necessary.

Fuel retainer

Please Note :
This operation should only be carried out when
the appliance is unlit and cold.
