Foreword
This document (EN 416-1:1999/A3:2002) has been prepared by Technical Committee CEN/TC 180 "Non-domestic
gas-fired overhead radiant heaters", the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by October 2002, and conflicting national standards shall be withdrawn at the latest
by October 2002.
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EU Directive(s).
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard : Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,

‘This standard is applicable to type A , A , B , B , B , B , C , C , C and C appliances intended for use in
2 3 12 13 22 23 12 13 32 33
other than domestic dwellings, in which the supply of combustion air and/or the evacuation of the products of
combustion is achieved by mechanical means located upstream of the draught diverter, if provided.’
3 Clause 2 Normative references
Add the following reference:
‘CR 1749:2001 European scheme for the classification of gas appliances according to the method of evacuation of the
products of combustion (Types)’.

Insert the following definition after 3.1.12:
‘3.1.13
premixed burner
a burner in which the gas and a quantity of air, at least equal to that theoretically necessary for complete
combustion, are mixed before the flame port(s)’.
Amend the definition numbers as follows (the definitions are to be retained):
‘3.1.14 ignition burner
3.1.15 ignition device

Type C : a type C appliance that is designed for connection via its ducts to a horizontal terminal, which at the same
1
time admits fresh air to the burner and discharges the products of combustion to the outside through orifices that
are either concentric or close enough to come under similar wind conditions.
Type C : a type C appliance incorporating a fan downstream of the combustion chamber/heat exchanger.
12 1
Type C : a type C appliance incorporating a fan upstream of the combustion chamber/heat exchanger.
13 1
Type C : a type C appliance that is designed for connection via its ducts to a vertical terminal, which at the same
3
time admits fresh air to the burner and discharges the products of combustion to the outside through orifices that
are either concentric or close enough to come under similar wind conditions.
Type C : a type C appliance incorporating a fan downstream of the combustion chamber/heat exchanger.
32 3
Type C : a type C appliance incorporating a fan upstream of the combustion chamber/heat exchanger.

See B.2 for the types of appliances identified above, in which the combustion air is supplied and/or in which the
products of combustion are evacuated either by natural draught or mechanical means.’

Insert the following after 5.1.4.2:
‘5.1.4.3 Soundness of the combustion circuit (type C appliances)
Parts which have to be removed during routine service and affect the soundness of the appliance and/or its ducts,
shall be sealed by mechanical means, excluding pastes, liquids and tapes. The need for replacement of the seal(s),
following a cleaning or servicing operation as stated by the manufacturer, is permitted.
However, parts of the assembly that are not intended to be dismantled for maintenance may be joined in such a
way, that permanent soundness is assured during continuous service under normal conditions of use.
The ducts, bends, if any, and the terminal or fitting piece shall fit together correctly and shall form a stable
assembly. Parts intended to be dismantled for periodic servicing shall be designed and arranged so that soundness
is guaranteed after re-assembly.
Any fitting piece shall allow a sound connection to be made to the system intended for the evacuation of
combustion products and supply of air.’
