2.2.4. Mounting of the Boiler to Wall and Selection of Installation Place
• Mounting of the boiler to wall must be checked and ensured to be stable
and safe.
• The hanger plate and connection screws supplied with the boiler shall
be mounted on a filled or semi-filled brick wall in accordance with the
installation scheme, and shall not be used for other purposes.
• In case any different materials are used for mounting, the warranty of the
boiler shall be terminated.
• If the wall to which the boiler is to be mounter is not brick, strength of the
support system shall be checked.
• The boiler shall be mounted on a fire resistant wall.
• The boiler should be mounted so as the height of the hanger plate to be
between 1,8-2,2 mm from the ground.
• The boiler shall be mounted with gaps as minimum 30 cm above the
ground, minimum 3 cm from both sides and minimum 90 cm from
the front side where the installation area is limited, for allowing easy
intervention of the service technician.
• The boiler shall not be installed in areas which contain or may contain
explosives, flammables and acid vapors.
• It shall not be installed next to or above ovens, cookers, radiators or
heaters.
• Hermetic boilers can also be installed in cabinets, provided that minimum
5 cm from each side is left.
• If the boiler is to be mounted over the kitchen countertop or kitchen set,
there shall be a minimum 50 cm distance under the boiler.
• Due to possibility of water draining from the Safety Valve of the boiler
after mounting, the outlet shall be connected to the drainage line. If this
is not possible; do not place electronic appliances, and tools, parts and
materials which may breakdown, be deformed or form rust.
• Any furniture should not be placed under the boiler due to the reasons
specified above.
• Make sure that there are no liquids or inflammable materials in the
immediate vicinity of the boiler.
• It is necessary to leave a spesific distance 1.0 mt between the heating
device and the building material containing combustible material even
the maximum allowable temperature value of 85 °C in the rated heat
capacity of the appliance is not exceeded.

2.2.5. Natural Gas Connection (Appliance Category I
2H
)
The boilers are designed to run on methane (G20) gas. Gas supply pipes
shall be equal to or larger than 3/4"G boiler fittings. Prior to making the
gas connection, a thorough internal cleaning shall be carried out to all fuel

supply installation pipe furnishings as possible wastes may distort smooth
operation and reliability of the boiler. Ensure that the gas supplied by the
mains line is of the type prescribed for the boiler (refer to the label on the
boiler).
Also, in case of reduced pressure, the network dynamic pressure (methane
or LPG) used for supplying the combi should be carefully controlled and
will impact the boiler strength. Ensure that gas valve connection is correct.
Flammable gas supply pipe should be able to supply correct adequate
gas amount to the boiler when the boiler is at full power and be projected
and sized according to force and local gas company specification and
instructions in order to guarantee the appliance efficiency. Connection
system shall comply with the legislation in force.
2.2.6. Flammable Gas Quality
The boiler is designed to be used with pure fuel not containing any foreign
substances; therefore, required filter systems must be available in the gas
supply line (for ensuring purification of the fuel).
2.2.7. In Case of Using Bottled Gas
• 300 mmSS pressurized hood should be used for LPG.
• 500 mmSS hood should not be used.
• 370 mmSS pressurized hood should be used for Propane.
• Do not place tubes at cold places having risk of snow for preventing frost
during winter months.
• Do not place tubes in hot places containing ovens, fireplaces for
preventing dangers!
• Do not make connection with single tube and use LPG collector set for
double, triple uses.
• The distance between the collector and tube should be maximum 125 cm.
• Copper pipe installation should not used for distances longer than 125 cm.
• Hose connection ends should be tightened with clamp and no other tools
should be used.
• Gas installation rules with use of LPG tank and industrial tubes should
comply with local standards and to be performed by expert installation
teams and certified by the company undertaking the construction. In case
of failing to fulfil these conditions, combi shall not be commissioned by
Warmhaus Authorized Services.
2.2.8. Heating and Domestic Hot Water Installations
Radiator and ground heating installation shall be configured in accordance
with technical specifications of the TSE (Turkish Standards Institution) and
MMO (Chamber of Mechanical Engineers), and according to the heat loss
calculation. Radiator type and amount and ground heating installation pipe
amount shall comply with the heat loss calculation.
• The design pressure strength of the heating installation shall be minimum
6 bar.
• If the mains pressure is more than 6.5 bar, a pressure reducer must be
fitted.
• It is recommended to construct the radiator installation as double line
and without using bends and joints as much as possible.
• Strainer filter shall be installed in heating return and tap water (city
network) intake line if a boiler is to be used.
• An additional expansion tank with 50 liters capacity shall be used
depending upon the volumetric capacity of the heating water of the
heating circuit (closed circuit) and working temperature.
• If room thermostat and thermostatic radiator valve are to be used
together; thermostatic valve shall not be installed in radiators in the
place where room thermostat is present.
• Cross connection must be made for efficient functioning in radiators
longer than 1,5 m.
• Covers shall be used for radiator and domestic hot water wall passages
and fixed with wall clamps to prevent expansions due to heating.
• An external boiler shall be fitted to the boiler for supply of domestic hot
water. In case of using domestic water boiler, the three-way valve and
boiler sensor within the product accessories.
