INSTALLATION AND OPERATING INSTRUCTIONS.
INTRODUCTION
SAFETY
Safety is the most important consideration when using and installing your stove. If not installed and used
correctly, a house fire could result. Installation must comply with relevant national and local Building
Regulations and fire safety standards.
IN THE EVENT OF CHIMNEY FIRE, EVACUATE THE PROPERTY AND CALL THE EMERGENCY SERVICES.
Your stove will be heavy, and care needs to be taken when lifting - 2 people will normally be required to lift.
UNPACKING
Your stove will have several of its components stored inside the stove itself for transportation.
Do NOT drag the stove on its legs –it must be carefully lifted into place.
You will also find a glove which must be used when opening the door or when adjusting air vents when the
fire is hot.
INSTALLATION
Installation of your stove must comply with relevant local and national Building Regulations and fire safety
standards.

The ST models have all passed the testing standard required for EcoDesign when burning wood logs.
The stove must not be installed within the specified minimum distances to combustible materials as shown in
the table above. Adjacent walls should be of non-combustible materials and construction, preferably masonry
or brickwork.
When installed inside a fireplace recess (with solid non-combustibles walls) we recommend a minimum 50mm
clearance at the sides and rear of the stove to allow good air circulation and achieve best performance.
Your stove will require a constant air supply and should not be used at the same time and in the same
room/space as extractor fans or any device which may draw air supply away from the stove.
The stove should be installed on a level floor with adequate load bearing capacity.
The stove needs to stand on a hearth of non-combustible materials not less than 12mm thick conforming to
Building Regulations.
A Carbon Monoxide detector must be fitted in the same room as the appliance.
NOT suitable for installation in a shared flue system.
If installed in a standard type chimney, a register plate needs to be fitted inside the chimney.
When purchasing flue pipe, 5” diameter is required. The flue pipe must be fitted INSIDE the flue spigot and
sealed with a generous amount of Fire Cement.
We recommend that you have a qualified fitter install your stove. The British recognised standard for solid
fuel installations is HETAS. You can find a HETAS qualified installer in your area by going to the HETAS website
–www.hetas.co.uk.

OPERATING INSTRUCTIONS
“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 by publication on a list by Scottish Ministers under section 50
of the Regulatory Reform (Scotland) Act 2014.
In Wales and Northern Ireland these are authorised by regulations made by Welsh Ministers and by the
Department of the Environment respectively.
Further information on the requirements of the Clean Air Act can be 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”
“The Saltfire ST2/ ST4 has been recommended as suitable for use in smoke control areas when burning wood.
Refuelling on to a low fire bed
If there is insufficient burning material in the fire bed to light a new fuel charge, excessive smoke emission can
occur. Refuelling must be carried out onto a sufficient quantity of glowing embers and ash that the new fuel
charge will ignite in a reasonable period. If there are too few embers in the fire bed, add suitable kindling to
prevent excessive smoke.
Fuel overloading
The maximum amount of fuel specified in this manual should not be exceeded, overloading can cause excess
smoke.
Operation with door left open
Operation with the door open can cause excess smoke. The appliance must not be operated with the
appliance door left open except as directed in the instructions.
Dampers left open
Operation with the air controls or appliance dampers open can cause excess smoke. The appliance must not
be operated with air controls, appliance dampers or door left open except as directed in the instructions.
FUEL
Wood only - All types of wood are suitable provided they are well seasoned, UNTREATED, and have a moisture
level between 12% and 20%. For soft woods, typically they will need to have been left in suitable storage for
9+ months in order for the moisture to evaporate. For hardwoods, this will usually be 18 months+. It is
recommended that logs should be no more than 4” or 125mm in diameter.
If you are unsure of the moisture content of your fuel, then you can buy a moisture meter which will indicate
the moisture levels in your fuel.

5
Liquid fuels must NEVER be used.
WARNING: Wet timber should not be used as this will create excess tar deposits in the chimney and stove and
could increase the risk of chimney fire. Timber which is not of a suitable moisture content will also create
more smoke and harmful emissions.
EcoDesgn 2022 Ready when burning wood as above.
Manufactured smokeless coals and anthracite can be used and will all have different qualities and effects. –
Do NOT use Petro-Coke based fuels or any petroleum-based fuels as this will invalidate the warranty. Do NOT
use coal that is designed only for open fires. Never use your stove as incinerator to burn waste or rubbish.
Never use your stove as incinerator to burn waste or rubbish. Never burn Petro-Coke or coals designed only
for open-fires.
