Premises.
Manufacturer's notes must not be taken in any way
as over-riding statutory obligations
C.E Approvals: The CE approval symbol means that
the PARAMOUNT fulfils the basic requirements of
the Gas Equipment Directive 90/396/EEC, the Low
Voltage Directive 73/23/EEC as well as Directive
89/336/EEC (Electromagnetic Compatibility EMC) of
the Council for Unification of Legal Regulations of the
Member Countries. The PARAMOUNT boiler fulfils
the basic requirements of the Boiler Efficiency
Directive 92/43/EEC for condensing boilers.
Corrosion Protection/Frost Protection
The combustion air must be free of corrosive
substances – particularly vapours containing fluoride
and chloride such as are contained in solvents and
cleaning agents, propulsion gases etc. When boilers
are connected to under floor heating systems with
plastic piping, which is not impermeable to oxygen,
heat exchangers must be used to separate the
systems.
System Water Quality
To ensure the boiler heat exchanger remains in good
condition it is essential to condition and monitor the
system water to the following criteria:
Water hardness: if the system fill water has a
hardness in excess of 250 mg/l (17.5°Clark) the
water should be softened prior to filling the system to
ensure that excessive scaling does not occur within
the heat exchanger.
Water acidity: the system fill water should have a pH
value between 7 – 8.3 to ensure corrosion of the heat
exchanger does not occur.
Copper ions: the copper content of the system water
should be less than 0.05 mg/l. If large quantities of
copper are present red and black copper oxide Cu
and CuO and grey/green copper carbonate, CuCo
will be produced. Copper will corrode any iron and
aluminium within the system.
treatment company should be consulted if in doubt.
Use of Inhibitors
If a requirement for i n hibitors exists ensure that the
pH value of the heating water does not increase to
above a value of 8.3 pH. Also observe specifications
of additive supplier.
hardness range above 3 as well as with heating
systems with large water volumes, a decision should
be made individually regarding the use of hardness
stabilising agents.

Recommendations can

Combustion Air

For conventional flue operation of the PARAMOUNT,
ensure that the installation room has a sufficiently
dimensioned opening for combustion air. Inform the
operator of the system that it is not permissible to
obstruct or plug the opening and that it is necessary
to keep the connection fitting for the combustion air
at the top of the PARAMOUNT free from obstacles.
Clean Combustion
PARAMOUNT is installed only in rooms with clean
combustion air. Ensure that pollen or similar cannot
penetrate through the inlet openings into the inside of
the equipment under any circumstances!
PARAMOUNT in Loft Space: If the PARAMOUNT is
used as a loft centre, POTTERTON recommends
installing a water catch pan below the hot-water tank.
Operation in Shower Room: When installed in
shower rooms, ensure that the following conditions
are fulfilled:
1. Balanced flue operation
2. To maintain protective system IPX4D
- Operate only with room control module RRG
in living area or
- Operate with heating circuit module HKM
(without EMS timer) with DSU timer in living
areas.
All incoming and outgoing electric cables

must be installed through and restrained by
pull relief glands. Tighten the glands tightly
so that water cannot get into the inside of the
housing!
