3.3 Chimney fire prevention measures:

Ordinary operation, especially with humid fuel, leads to the settling of ash and tar in the

chimney. Neglecting regular checking and cleaning of the chimney in accordance with Building

Regulations increases the danger of fire. We recommend that the chimney should be swept

twice a year.

In case of ash or tar catching fire in the chimney, please follow this procedure:

• do not under any circumstances extinguish the fire with water as it would create an

abnormal amount of steam and subsequently rip the chimney open

•

if possible, the combustion chamber should be covered with dry sand, which will extinguish

the fire

• close all intakes of air for combustion; if possible, cover the chimney. However, the smoke

must not accumulate back in the house

• contact your nearest fire fighting brigade to assess the situation and the necessity to

report it as a fire fighting emergency

• do not leave the house until the chimney is burned up; regularly check the chimney

temperature and the course of combustion

• contact a chimney service engineer before starting a new fire in the stove to assess the

state of the chimney and also contact the manufacturer of the fireplace stove for inspection.

The installation must comply with current Building Regulations, National and European

Standards, Local Authority byelaws and other specifications or regulations as they affect the

installation of the stove. The Building Regulations requirements may also be met by adopting the

relevant recommendations in the current issues of British Standards BS 8303 and BS EN15287-1

The appliance must be fitted by an approved installer or inspected and signed off by a Building

Control officer.

Note: It is a requirement where a new or replacement fixed solid fuel appliance is installed in a

dwelling that a sealed carbon monoxide alarm to standard BS 50291:2001 is fitted in the room

where the appliance is fitted and fixed as described in Building Regulations Document J section

2.34 – 2.36.

The fireplace stoves must be installed on a floor with an adequate bearing capacity. If the

existing arrangement does not meet this basic requirement, necessary steps must be taken

(e.g. using a hearth for distributing the load). Make sure that there is enough space and

provision for cleaning and servicing the fireplace stove, connecting flue pipes and the chimney.

Before installing the appliance the chimney construction should be checked to confirm that

it will be suitable for the installed fireplace stove nominal output as far as design, ventilation

requirements and effective height are concerned. A suitable chimney (minimum profile,

chimney draft, tightness, etc.) is a basic condition for the proper functioning of the fireplace

stoves. Chimney values are included in the attached technical sheet. The connecting flue pipe

should not be smaller than the cross sectional area of the appliance flue gas outlet.

A draught regulator should be installed for chimneys with too strong a flue draught. Such a

draught can cause problems during operation, e.g. intensive burning, high fuel consumption

can also lead to permanent damage of the fireplace stove. Too weaker draught leads to glass

blackening or to smoke escaping into the room when opening the door and stoking fuel.
