5.7De-ash the fire bed before re-fuelling, see Section 7 Ash Removal.

•Open the Primary air control fully to establish a glowing bed before adding new fuel

•Burn new fuel at high output for a few minutes before adjusting the Primary air control to the desired setting

•Refuel little and often for clean, efficient burning.

5.8Experience establishes control settings to suit personal preferences

5.9Do not burn large amounts of fuel with the Primary Air Control on low settings for long periods of time. This reduces the glass cleaning effect of the air wash and causes tars and creosotes to build-up in the appliance and flue system.

5.10When in use, burning the appliance at high output for a short period also reduces tars and creosote.

5.11You must burn only anthracite or smokeless fuels suitable for use in closed appliances.

5.12Do not burn bituminous coal, ‘petro-coke’ or other petroleum based fuels as this invalidates the product guarantee.

Do not load fuel above the log guard and the secondary combustion inlets at the back of the firebox.

See Diagram 7

6.1Fuel Quality (Wood)

Use wood with a moisture content of less than 20%. Seasoned logs have the bark beginning to lift and peel away and cracks radiating from the centre. They feel lighter than fresh cut wood of a similar size and sound hollow when struck against each other. Logs should not feel damp or have moss and fungal growths.

Symptoms related to wet wood:

—Difficulty starting and keeping a fire burning well

—Smoke and small flames

—Dirty glass and/or firebricks

—Rapid creosote build-up in the chimney

—Low heat output

—Short burn times, excessive fuel consumption and blue/grey smoke from the chimney

• Burn at high output at high output for a short period each day to avoid large build-ups of tars and creosote within the appliance and the flue system

• Use Stovax Protector chimney cleaner to reduce this problem

6.2 Fuel Quality (Solid Fuel)

• Use recommended solid fuels approved for use with closed appliances.

Symptoms related to unsuitable fuels include:

— Difficulty starting and keeping a fire burning well

— Smoke and small flames

— Dirty glass and/or fire bricks

— Short life span for grate, baffles and internal firebricks

— Permanent staining of glass

6.3 Air inlets puffing smoke

Combustion gases build up in the firebox and ignite as small explosions, causing smoke to puff out of the air inlets and other openings. This occurs if the air controls are shut soon after adding new fuel to a very hot fire. Stop by opening the air controls to increase combustion air and burning rate.

6.4 Flue Draught

The chimney has two main functions:

1) To safely remove the smoke, gases and fumes from the house.

2) To provide a sufficient amount of draught (suction) in the appliance ensuring the fire keeps burning.

Draught is caused by the rising hot air in the chimney when the appliance is lit.

Symptoms of poor performance related to flue draught include:

— Excessive fuel consumption (high flue draught)

— Poor burning control, overheating (high flue draught)
