6.3Flue 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)

—Wind noise from air controls (high flue draught)

—Difficulty getting a fire going and keeping it burning well (low flue draught)

—Low heat output (low flue draught)

—Smoke entering room when doors opened (low flue draught)

The construction, position, size and height of the chimney all affect the performance of the flue draught.

Other factors effecting the flue draught include:

—Trees or other buildings nearby causing turbulence

—High and gusty winds

—Outside temperature

—Outside weather conditions

—Incorrect additional ventilation to building

—Blocked flue / chimney

For advice on the correction of persistent flue problems consult a qualified solid fuel heating engineer before continuing to use the appliance.

6.54Weather conditions

The weather conditions outside the building can effect the burning performance of the appliance. These could include:

Weather Conditions	Problem	Effect
Windy days	Buildings/Obstacles	Smoky Appliance
	cause turbulent air
	around chimney.
Calm days	Oversized Chimney.	Smoky Appliance
Damp / Rainy days	Flue temperature	Lighting and
	not hot enough.	burning problems
	Rain water inside
	chimney.

To reduce these problems:

•Use good quality kindling wood to start the fire

•Burn initially at a high temperature for a short period

• Fit a rain cowl to the chimney

Your installer should advise you on possible solutions.

If the appliance emits smoke into the room continuously:

•Allow the appliance to go out

•Ventilate the room to clear the fumes

Do not re-light the appliance until the problem is solved.

7. ASH REMOVAL

Do not allow ash to build up in the appliance as it will not burn properly and may cause damage.

7.1Wood:

Regular cleaning:

•De-ash at least once a week by removing ash from the log box whilst located in the appliance

•Leave a thin layer of ash to start the new fire on

Thorough cleaning:

• Remove the Log bar/front by lifting vertically

Where a Steel frame is fitted the removable bottom frame plate must be removed prior to lifting out the log box, Installation Instructions 3A.

•Lift the Log box above the bottom lip of the frame opening

•Clean the log box and any ash on the appliance base plate

7.2Multi-fuel:

De-ash the appliance before filling with new fuel. Do not allow ash to build up on the underside of the grate as this can cause premature failure.
