 INSTALLATION INSTRUCTIONS

PRE LIGHTING CHECK

Before initial lighting check the following points:

1. The bottom grate bars must all be fitted and should move freely 
and easily when the riddling mechanism is operated.
2. The plates round the sides and back of the grate must be in 
position and sitting correctly.
3. The throat plate must be fitted in the roof of the appliance (as 
shown in Fig. 9).
4. Check that the front fence is fitted correctly and that the door 
closes properly.

COMMISSIONING

On completion of the installation allow a suitable period of time for 
the fire cement and mortar to dry out before commissioning the 
fire. Before lighting, first check that there is an updraft in the 
chimney - open the door of the stove and hold a lit match at the top 
of the door opening. If the flame is pulled into the stove this indicates 
that there is an updraft and the fire may be lit. If the flame is pushed 
out from the stove then this indicates that a downdraft is present, 
the flue will need to be warmed to produce an updraft and then 
checked using the same procedure with the lit match. The flue may 
be warmed by lighting a single sheet of newspaper, or a firelighter, 
within the stove before attempting to light a proper fire. Sometimes 
it may be necessary to open a window to give an initial draw.

A spillage test must be carried out to confirm safe operation with 
doors and windows closed and any extract fans in operation (i.e. 
worst conditions) Warm the appliance and flue before carrying out 
the spillage test. Light a smoke match from the middle of a bed of 
embers, hold the match approximately 20mm above the ember bed 
and ensure that the smoke is carried up the flue and emitted safely. 
Also check all joints and seals. On successful completion of the 
spillage test please leave the operating instructions and tools with the 
customer and advise them on the use of the appliance. If the spillage 
test fails the cause must be found and rectified, or the appliance 
decommissioned and the customer instructed  not to use the 
appliance until it can be shown to operate safely.

CAA AND SMOKE CONTROL

The Clean Air Act 1993 and Smoke Control Areas

Under the Clean Air Act local authorities may declare the whole or 
part of the district of the authority to be a smoke control area. It is 
an offence to emit smoke from a chimney of a building, from a 
furnace or from any fixed boiler if located in a designated smoke 
control area. It is also an offence to acquire an "unauthorised fuel" 

for use within a smoke control area unless it is used in an "exempt" 
appliance ("exempted" from the controls which generally apply in 
the smoke control area).

In England appliances are exempted by publication on a list by the 
Secretary of State in accordance with changes made to sections 20 
and 21 of the Clean Air Act 1993 by section 15 of the Deregulation 
Act 2015. Similarly in Scotland appliances are exempted 
bypublication on a list by Scottish Ministers under section 50 of the 
Regulatory Reform (Scotland) Act 2014.

In Northern Ireland appliances are exempted by publication on a list 
by the Department of Agriculture, Environment and Rural Affairs 
under Section 16 of the Environmental Better regulation Act 
(Northern Ireland) 2016.

In Wales appliances are exempted by regulations made by Welsh 
Ministers.

found here: https://www.gov.uk/smoke-control-area-rules

Your local authority is responsible for implementing the Clean Air 
Act 1993 including designation and supervision of smoke control 
areas and you can contact them for details of Clean Air Act 
requirements.
