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;
---------------------- Page: 5 ----------------------
EN 1:1998/A1:2007 (E)
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.

8 Evaluation of conformity
8.1 General

The compliance of fuel oil stoves with the requirements of this standard and with the stated values (including

classes) shall be demonstrated by:
 initial type testing according to test requirements in Clause 6;
 factory production control by the manufacturer, including product assessment.

For the purposes of testing, appliances may be grouped into families, where it is considered that the selected

performance characteristic or characteristics listed below is/are common to all appliances within that family:

 Reaction to fire
 Release of dangerous substances
 Surface temperature
 Electrical safety
 Rated thermal output
 Durability
8.2 Type testing
8.2.1 Initial type testing

Initial type testing shall be performed to demonstrate conformity to this standard. In the case of an appliance

already in production the appliance to be tested according to test requirements in Clause 6 shall be chosen at

random and be representative of general production and the manufacturer shall provide a written declaration to this

effect.

In the case of a prototype the appliance tested shall be a model representative of the intended future production

and the manufacturer shall provide a written declaration that this is the case.

Tests, according to test requirements in Clause 6, previously performed in accordance with the provisions of this

standard (same product, same characteristic(s), test method, sampling procedure, system of attestation of

conformity, etc.) may be taken into account. In addition, initial type testing shall be performed either at the

beginning of the production run of a new oil stove type (unless a member of the same family) or at the beginning of

a new method of production (where this may affect the stated performance characteristics) and at least a check of

constructional characteristics on one further production run appliance of each type over an on-going period not

exceeding 3 years to monitor consistency of manufacture and conformity to type.

For a family or range of appliances it shall be permissible to test, according to test requirements in Clause 6, only

selected appliances across the family or range and to only verify selected constructional and performance

characteristics on the others, subject to a clear decision being made that the appliances are part of a family or

range of appliances.

In deciding that the appliances belong to a family or range due account shall be taken of the performance

characteristics. Tests according to requirements in Clause 6 previously performed in accordance with the

provisions of this standard (same product, same characteristic(s), test method, sampling procedure, system of

attestation of conformity, etc.) may also be taken into account in making the decision.

---------------------- Page: 13 ----------------------
EN 1:1998/A1:2007 (E)

The parameters and characteristics considered in making the decisions in relation to the family or range of

appliances shall be recorded and a copy included in the production documentation for each appliance of the family

or range (see 7.3).

For the initial type test at least a sufficient number of the appliances shall be chosen from across the family or

range so as to represent adequately the family or range. The chosen appliances shall be subjected to complete

testing to fully verify their compliance with all of the constructional and performance characteristics in accordance

with this standard. For the other appliances in the family or range not chosen for complete testing it shall be

permissible to only verify selected constructional and/or performance characteristics to ensure their compliance

with the requireme
