situation it is necessary to treat the water with an
appropriate corrosion inhibitor.
- Any treatment of water by additives in the system for
frost protection or for corrosion inhibition has to be
absolutely suitable for all the metals used in the circuit.
The use of a corrosion inhibitor in the system such as
Fernox MB-1, BetzDeaborn Sentinel X100 or Fernox
System Inhibitor is recommended to prevent corrosion
(sludge) damaging the boiler and systems;
- If anti-freeze substances are to be used in the system,
check carefully that they are compatible with the metals
used in the circuit.
MTS suggests the use of suitable anti-freeze products
such as Fernox ALPHI 11, which will prevent rust and
incrustation taking place.
Periodically check the pH of the water/anti-freeze
mixture of the boiler circuit and replace it when the
amount measured is out of the range stipulated by the
manufacturer ( 7 < pH < 8).
DO NOT MIX DIFFERENT TYPES OF ANTI-FREEZE
- In under-floor systems, the use of plastic pipes without
protection against penetration of oxygen through the
walls can cause corrosion of the systems metal parts
(metal piping, boiler, etc), through the formation of
oxides and bacterial agents.
To prevent this problem, it is necessary to use pipes
with an "oxygen-proof barrier", in accordance with
standards DIN 4726/4729. If pipes of this kind are
not used, keep the system separate by installing
heat exchangers of those with a specific system
water treatment.
IMPORTANT
Failure to carry out the water treatment procedure will
invalidate the appliance warranty.

ONDENSATE ISCHARGE
A flexible hose connected to the bottom of the boiler
should be inserted into a tundish (not supplied).

OTE T MAY BE NECESSARY TO REMOVE THE CASING TO PULL
THE CONDENSATE HOSE OUT OF THE BOTTOM OF THE BOILER
The condensate discharge hose from the boiler must
have a continuous fall of at least 2.5° and must be
connected to a visible tundish and inserted by at least
50mm into a suitable acid resistant pipe with a nominal
diameter of 32mm e.g. plastic waste pipe or overflow
pipe. The condensate discharge pipe must have a
continuous fall and preferably be installed and terminated
within the building to prevent freezing.
The discharge pipe must be terminated in one of the
following positions, allowing for a safe discharge:
i) Connecting in to an internal soil stack (at least 450 mm
above the invert of the stack). A trap giving a water
seal of at least 75 mm must be incorporated into the
pipe run, there also must be an air break upstream of
the trap i.e. tundish.
