Add the following text:
The stove shall be fire-resistant and safe to operate, and shall be designed such that
no visible deformations following the performance tests according to Clause 6 occur;
it can withstand the stresses arising during normal operation;
the burner and the stove cannot become heated to create a hazard;
dangerous accumulations of combustible gases (fuel mixed with air) in the combustion chamber and in the
flues are prevented (for automatically operated burners only);

following:
components of accessories e.g. burner covers, if the parts are fitted outside of the boiler;
internal components of controls and safety equipment;
operating handles;
electrical equipment.
Component parts of covers, operating, control and safety devices and electrical accessories shall be arranged in
such a way that their surface temperatures, under steady state conditions, do not exceed those specified either by
the manufacturer or in the component part standard.
NOTE Because the entire heat dissipating surfaces of the appliance including the flue spigot/socket and the flue gas
connector are working surfaces, there is no requirement for limiting the surface temperature of the appliance.

Add the following text at the end of the subclause:
It shall not be possible to remove any component in the oil supply line to the burner without the use of a tool.
4.10 Built-in storage tank

To ensure that any fire external to the stove is not transmitted to the contents of the built-in storage tank or, if a fire
does occur, its effects are limited by either the tank being made of non-combustible materials e.g. metal or be
enclosed with non-combustible fire resisting materials or construction. Any fuel lines from the tank to the burner
shall also be fire resistant.
The filling orifice of the built-in storage tank shall have a cap and shall be easily accessible and it shall be so
arranged that when filling the tank with fuel it is not possible to ignite the fuel from any hot components.
4.12 Drip tray
Replace the text of the subclause with:
Any stove incorporating a built-in storage tank shall incorporate a drip tray, below the parts of the stove containing
fuel, for the collection of any spillage, having an edge height of a least 10 mm (inside depth) and capacity of a least
1 dm³.
Add the following new subclause:
4.18 Additional requirements for appliances with automatic burners
The burner and control system in combination shall be such that, in the event of failure to ignite when starting, the
burner will assume a safe condition (lock-out) and will require a manual reset of its sequencing control. In the event
of a flame failure occurring when running, the appliance shall fail safe.
A temperature or pressure sensing device shall be provided on the appliance to start and stop the burner. In
addition, a separately operating limiting device shall be provided to stop the burner before the temperature in the
appliance exceeds safe limits.
Controls and safety devices shall be coupled so that operation of each occurs in the correct sequence and timing;
coupling may be electrical or mechanical. The controls and safety devices shall:
a) ensure that the start-up sequence is not able to commence unless the flame sensing equipment has confirmed
the no-flame condition;
b) establish satisfactory ignition of the oil;
c) maintain normal operation if the flame is satisfactorily established, and switch off ignitor;
d) automatically vary the burner firing rate, where applicable;
e) stop the burner when the demand for heat is satisfied;
f) stop the oil supply and lock-out system if flame is not satisfactorily established;
g) provide means for a visible or audible indication that the unit is in a lock-out condition;
h) ensure that any interruption of the electricity supply does not give rise to a dangerous condition.
If the control sequences are such that an attempt to re-ignite the burner can be made the burner shall either:
i. ignite and burn in a safe manner whilst the surplus oil is burnt off and the burner is returning to normal
operation conditions; or
ii. not ignite.
Manually operated dampers or other movable devices for restricting the flow of gases shall not be fitted.
Automatically operated dampers, if fitted, shall be interlocked with the fuel supply and arranged so that the burner
cannot operate with a closed flue.
