When applied in such manner the installation
instructions contained in this document must be
complied with as appropriate. The fitting within another
housing must take into account the gas fired appliance
requirements of the appropriate CE standard, EN
1020 " Non-domestic gas-fired forced convection air
heaters for space heating incorporating a fan to assist
transportation of combustion air and/or flue gases"
PrEN 1020 is in
course of preparation and may be applied until the
final document is published, (anticipated 1996)
1.11 The criteria recommended in this document regarding
airflow pressures, temperature rise, firing rates and
fitting methods must be strictly complied with, whether
or not the appliance is used as a duct heater or as part
of an multi-functional appliance, to ensure satisfactory
operation.
