2.5. HEATER AND HOT DOMESTIC WATER
INSTALLATIONS
Radiator and floor heating installations should be performed according
to TSE and MMO technical specifications according to heat loss
calculation. The type and quantity of the radiator and the quantity of
piping of the heating installation must also be appropriate for the
calculation of heat loss.
• The heating installation must be installed at a pressure enduring at
least 6 bar.
• If the city pressure is higher than 6.5 bar, the pressure reducer must
be assembled.
• It is recommended that the heating installation be performed as
double or mobile line (at least) and avoiding the elbows and joints
as many as possible.
• A strainer filter must be definitely installed in return line of heater and
if a hot water tank will be used, in inlet line of domestic water (city).
• An additional expansion tank of at least 50 litres should be used
depending on the volume of the heating water and the working
temperature of the heating circuit (closed circuit).
• If room thermostat and thermostatic radiator valve will be used
together; the thermostatic valve should not be installed in radiators
in places where the room thermostatic available!
• Radiators longer than 1.5 m must be cross-connected for efficient
operation.
• Sheaths should be used in the passages of the heating and hot
water from the walls and they should be fixed with wall clamps so
as not to incline in the expansion due to heating.
• For Hot Domestic Water supply, an external hot water tank must be
connected to the boiler. In case of use with a hot water tank, the
three-way valve and hot water tank sensor in the product accessory
group must be used.
• The heater must be washed and cleaned of dirt before filling!
2.6. FILLING THE SIPHON 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 10).
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.
2.7. 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 outdoors, 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: Ø100 / 100 Waste Gas Chimney Block with 153.11.660.600040
product code or (Ø100-Ø100) 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 staring 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.
