with all windows and doors shut in the room where the appliance

is fitted.

If a ceiling fan is present it must be operated on max for the duration

of the test. If there are any extraction fans in adjacent rooms these

too must be operated on maximum setting during the test with the

interconnecting doors open. If any spillage occurs, recheck the

suitability of the flue system making sure there is adequate air

supply to the room (as per Building Regulations).

Light the appliance and slowly increase the temperature to

operating levels. Open the main fire door when the appliance

reaches normal operating condition and carry out a spillage test

using a smoke match or pellet around the door opening. If any

spillage occurs, open all windows, allow the fire to go out and

recheck the flue system and ventilation.

Operating Instructions

Warning: The door and operating handles become hot when

the stove is in use. For your safety use the glove provided.

Initial Firing of Stove

We recommend that you have two to three small fires before you

operate your stove to maximum heat output. This is to allow the

paint to cure and the castings to relax and consolidate location.

We recommend this 'running in' procedure after long idle periods

to preserve the life of the stove. During this you may notice an

unpleasant smell. It is not toxic but for your own sake we would

suggest that during this period you leave all doors and windows

open.

Air Controls

Primary air is controlled via the sliding vents (A - Fig 9) in the bottom

of the door; this provides a conventional air draught to the bed of

the fire. (+) indicates more air, (-) indicates less air, (+) and (-) are

marked on the primary and secondary air controls.

Secondary air is controlled via the sliding vent (B - Fig 9) above

the door. It is this 'Airwash' that keeps a clean and uninterrupted

view of the fire, also aiding in good secondary combustion of fuel

and reducing emissions into the chimney and environment.

Lighting the Stove

Place fire lighters or paper and kindling on the grate. Light the

fire at base leaving all air controls open. Allow the fuel to reach a

steady glow across the grate and build the fire up gradually. Once

you have a good fire established across the grate bed, further fuel

can be added as required.

Running the Stove

When your fuel is well alight you can start to restrict the air intake.

If you are only burning wood the primary air control can be fully

closed. If you are burning solid fuel you will require more primary

air. Your stove is burning with maximum efficiency when a bright

fire is achieved using minimum air inlet.

When refuelling the stove, fully open the primary and secondary air

controls for a few minutes until the new refuel charge is well alight.

the air controls can then be closed again to the desired setting.

Never leave the stove unattended until the logs are burning well

and the air supply has been adjusted down to desired level.

Note that refuelling onto a low firebed causes excessive smoke

to occur. Refuelling must be carried out onto a sufficient quantity

of glowing embers to ignite fuel in a reasonable period. If there

are too few embers add kindling first to get fire going again before

refuelling.

For optimum performance the stove should not be overfilled

with fuel above the height of the rear brick. This will cause poor

operation and can cause excessive smoke to occur on ignition. The

stove must not be operated with the appliance door left open.

The stove can be banked up for long periods. When burning solid

fuel empty the ash pan. Open air controls and let the fire burn

brightly for a short period. Refuel and close air controls; the exact

setting required will depend on the fuel used and the chimney draw

so some practice may be necessary. To revive the fire, open air

controls until the fire is burning brightly, de-ash if necessary and

refuel. Set air controls as required. The stove is not suitable for

overnight burning.

Notes on Wood Burning

Wood burns best on a bed of ash and it is therefore only necessary

to remove surplus ash from the grate occasionally. Burn only

dry, well seasoned wood, which should have been cut, split and

stacked for 12 months with free air movement around all sides

of the stack to enable it to dry out. Burning wet or unseasoned

wood will create tar deposits in the stove and chimney and will not

produce a satisfactory heat output. When loading wood, make sure

that the end grain of the wood in the stove is pointing away from

the glass otherwise the moisture and gases coming from the end

grain of the wood will dirty the glass.

Notes on Solid Fuel burning (Other than Wood)

Always de-ash the grate before refuelling and do not let the ash

build up to the underside of the grate bars. If ash is allowed to

build up it will stifle the air flow through the grate and will eventually

cause the fire to die. Air passing through the firebed cools the

grate. Distortion or burning out of the grate bars is nearly always

caused by ash being allowed to build up on the underside of the

grate. With some solid fuels a residue of burnt fuel or clinker will

accumulate on the grate. It is important it is to empty the ash pan

and remove clinker after each firing of the stove.

We recommend the use of approved manufactured smokeless fuels.

Note that different types of fuel will give different performances.

Use as an incinerator for household waste is not recommended

as fumes from plastic, etc will cause pollution to the atmosphere

and will cause damage to the stove. Should any difficulties arise

over fuel quality or suitability, consult your local supplier or contact

the Solid Fuel Advisory Service.

Petroleum coke fuels or household waste should not be

burned on this appliance.

De-Ashing

To de-ash the grate draw the riddle lever forwards and backwards

with a slow positive action (D - Fig 9).

The ash pan should be emptied each time after operating the stove

so not to let build up of ash occur. Where possible, it is best to

wait until the stove and ash has cooled before removing the ash

pan. To remove, open the stove door by lifting the handle upward

(C - Fig 9) then using the hand tool lift the ash pan out of the fire

(Fig 10). For efficient burning of your appliance, make sure the

grate is clear of burnt debris; e.g. nails, etc.

Shut down Periods

If shutting down the stove for long periods (e.g. for summer months)

make sure that all ash is removed from the stove and that the

chimney flue ways and baffle plate are brushed clean. When the

stove is cold a vacuum cleaner may be used to remove any residual

ash or soot. Close the door and leave all air inlets open fully. This

action will ensure air circulation through the appliance and will help

to avoid corrosion and condensation within the appliance during

this shut down period.
