2.2. HEATING AND DOMESTIC HOT
WATER SYSTEMS
Radiator and underfloor heating installation should be
constructed in accordance with legislation in force technical
specifications and heat loss calculation.
• Heating system must be installed to resist pressure up to at
least 6 bar.
• Pressure reducer must be installed if the mains pressure is
above 6,5 bar.
• It is recommended to install heating system as (at least)
double or mobile line by avoiding bends and additions as
much as possible.
• A strainer filter must be installed in heating return line and, if
DHW boiler (mains) is being used, in inlet line.
• Additional expansion tank with at least 50 liters must be
used according to the heating water volume capacity and
operating temperature of the heating system (closed circuit).
• If the valves of room thermostat and thermostatic radiator
are going to be used together; thermostat valves shouldn’t
be installed to radiators in the places where there’s room
thermostat!
• Cross connection must be made for efficient operation in
radiators longer than 1,5 m.
• Covers shouldn’t be used in the transitions of heating and
domestic hot water from walls, and wall clamps must be
immobilized not to slope in expansions due to heating.
• An external DHW boiler must be connected to the boiler for
Domestic Hot Water supply. It is necessary to use three way
valve and DHW boiler sensor in the product accessory group
in case of usage with DHW boiler.
• Heating system must be washed and cleaned up before
filling!
2.3. FILLING THE FLUSHER FOR
CONDENSATION LINE
The condensation siphon must be filled with water after
completing wall-hanging of the condensation boiler, electrical
connections, heating lines, hot domestic water connections and
condensate drainage line (Figure 2.2).
Condensation line outlet connection must be sealed.
However, against the risk of waste gas leak in the first
operation, pout about 1 litre of water into the chimney
before chimney-mounting of siphon in the boiler. Thus, the water
in the siphon will prevent the leakage of waste gas.
The tilt of the condensation water hose and line must always be
downward.
2.4. CONNECTION OF WASTE GAS
CHIMNEY PIPE SET AND ACCESSORIES
Chimney accessory of hermetic boilers sets to be used
in the waste gas installation should be original
Warmhaus chimney sets and they should be used taking
into account sizes and restrictions given in the mounting
instructions.
If different waste gas pipes and/or accessories are used
other than original Warmhaus waste gas chimney pipes
and accessories, the boiler will not be started by the
Authorized Service and therefore cannot be guaranteed!
The boiler should only be mounted with plastic material and the
original Warmhaus air intake and waste degazing device.
Plastic ducts cannot be installed outsides, at intervals over
40 cm, without proper protection against UV and weather
conditions. Each pipe is identified by a promoting and distinctive
Warmhaus sign in the notes.
If more than one Viwa 90-150 boilers are connected in
parallel to the same hydraulic installation and operated
as cascade, it is necessary to use the product code for
each boiler is: O100 / 100 Waste Gas Chimney Block with
153.11.660.600040 product code or (O100-O100) Chimney Block
products with 153.11.660.600068 product code must be used for
each boiler. In the same installation, the blocks should not be
used together and the same block product should be used for
each boiler.
If the Viwa 90, Viwa 115, Viwa 125 and Viwa 150 boilers are
used as cascade systems and our blocking products are
not used in each boiler, boilers will not be started by our
authorized service!
IMPORTANT
The following must be checked during starting the
boiler:
- Make sure that there is no liquid or combustible
materials near the boiler.
- Ensure that the electrical connections are made correctly and
that the ground wire is connected to a good grounding system.
- Open the gas valve and check the durability of connections
including the burner, burner exchangers and heat exchangers.
- Ensure that the boiler is adjusted for operating for the supplied
gas type.
- Check that the chimney pipe in outlet of combustion products
is not blocked and is properly mounted.
- Make sure that any (safety) shut-off valve is open.
- Ensure that the system is filled with water and thoroughly
ventilated.
- Check that the circulation pump is not jammed.
- Discharge the air that may be in the gas line, discharge the air
in the gas pipe by operating the pressure discharge valve at the
gas pipe inlet.
