4.1 REGULATIONS
PRIVATE HOMES
STATUTORY REQUIREMENTS FOR INSTALLATION AND
MAINTENANCE
Installation and maintenance of the equipment must be car-
ried out by a qualified professional in accordance with cur-
rent legislative texts and state of the art, including:
- law of 2 August 1977
Technical and Safety rules applicable to combustible gas
and liquefied gas petroleum installations located inside
buildings or outbuildings
- law of 5 February 1999 modifying the law of 2 August
1977
after replacing a boiler with an identical one (same align-
ment and area as the previous equipment), the installer
must make out a "model 4" certificate of conformity
- Standard DTU P 45-204 -
gas installations (previously DTU N°61-1 - Gas
Installations - April 1982 + additional clause N°1 of July
1984)
- Regional Health Regulations
Protection of the drinking water network:
• articles 16-7 and 16-8 of the Regional Health Regulations
require the installation to have a CB type disconnection
device with various non-controllable pressure zones,
conforming to the functional requirements of French
Standard NF P 43-011, to prevent heating water being
returned to the drinking water network
• an NF backflow preventer is fitted in the boiler's tap fit-
tings unit
• French Standard NF C 15-100 - Low voltage electrical
installations - Rules
PUBLIC BUILDINGS
STATUTORY REQUIREMENTS FOR INSTALLATION
Installation and maintenance of the equipment must be car-
ried out by a qualified professional in accordance with cur-
rent legislative texts and state of the art, including:
- fire safety and panic control regulations for public
buildings:
a) General requirements
for all equipment:
• GZ articles
combustible gas and liquefied gas petroleum installations
• CH articles
heating, ventilation, refrigeration, air conditioning, steam
and domestic hot water production
b) Special requirements for each type of building with
public access (hospitals, shops, etc.)
Recommendation:
if the area is exposed to the risk of lightning (isolated ins-
tallation at the end of an electricity line, etc.) install a light-
ning conductor
Our warranty is subject to this requirement.
4.2 BOILER LOCATION
- the centre line of the external flue duct must be placed at a
distance of at least 0.40 m from any opening window and
a distance of at least 0.60 m from any ventilation hole
(depending on the type of outlet chosen, refer to the flue
kit instructions)
- if the boiler is installed in a bathroom, comply with the spe-
cial safety regulations in French standard NF C 15-100
(section 7)
- never install the boiler above hot-plates or ovens or in
general over any equipment producing greasy vapours
which could make the boiler dirty and affect its operation
- prepare a wall and mountings able to support the weight of
the boiler (weight: approx. 35 kg)
- take precautions to reduce noise
4.3 DESIGNING AND CARRYING OUT THE INSTALLA-
TION
Domestic hot water circuit (system plus)
- Avoid excessive loss of charge in preheating circuit
- if the water hardness is more than TH 25, install a water
softener
- if a non-return valve is present, a device allowing for
expansion is required (available as an option)
See domestic hot water technical directive (DTU)
Central heating circuit
Circulation flow rate:
- when working out the measurements, be careful to main-
tain a minimum flow rate of 300 I/h with the thermostats
closed
Precautions against corrosion
Operating faults due to corrosion are likely to occur if the
system is built with components made of different materials.
To prevent such problems it is advisable to use a corrosion
inhibitor.
Take every precaution to prevent the treated water from
becoming corrosive.
Old installation:
- fit a sediment trap to the lowest point on the return and
treat the system correctly
Recommendation:
- fit bleed valves on all radiators and to high points of the
installation; also fit drain cocks to low points
