THERM 90 KD.A
3.3 Location of the boiler
The condensing boilers THERM can be installed in the basic AA5/AB5
environment according to ČSN 33 2000-3 and ČSN 33-2000-5-51 ed. 3 (range
of tempe5 to 40°C, moisture depending on the temperature up to
a maximum of 85 %, without harmful chemical influences). The combustion
air must not contain halogen-hydrocarbons and vapours from aggressive
substances, and must not have high moisture and dust levels.
The THERM 90 KD.A series boilers are located usually to the non-residential
areas (boiler rooms). When the boiler itself is located near the residential area,
it is suitable to adjust limit of the boiler maximum power (however with regard
to the object thermal needs) to to lower edge of the loss power range due to
the lower noise level of the boiler at the lower power operation.
The hanging condensing boilers THERM
must not be
installed in premises
with bath-tubs, bathrooms, washing areas and special zones 0, 1 and 2
according to ČSN 33 2000-7-701 ed. 2: 2007 and in washing area according to
ČSN 33 2130 ed.2: 2009. Insulation protection of electric parts IP 41 (D) complies
with conditions of resistance against vertically dropping water. The place of
installation must be selected to be able to have access in the case of operation
and service inspection. The recommended distances are specified on following
figure.
Notice:
Items pursuant to ČSN 06 1008 must not be located near the contour of the boiler (classified according to ČSN EN 13501-
1+A1:2010) to the smaller distance as:
100 mm
from materials B – easily flammable, C1 – heavy flammable or C2 – medium
flammable
200 mm
from materials C3 – light flammable (e.g. wood-fibre boards, cellulose substances, polyurethane,
polystyrene, polyethylene, PVC, etc.)
The safe distance between flammable items and the boiler is 50 mm; from the chimney flue and the control hole 200 mm.
Flammable items must not be located at lower distances. The wall on which the boiler will be suspended must be constructed
from fire-proof material.
Before starting work that may cause a change of the environment in the area of the installed boiler (e.g. work with painting
substances, glues, etc.), it is necessary to disconnect the boiler using the regime switch (position with the pointer on “0“) and
to disconnect it from the electricity network (remove the network fork from the socket).
3.4 Suspending the boiler
THERM hanging boilers in the 90 KD.A serie are suspended on the wall by the suspension bar delivered with the boiler
according to the diagram.
Procedure for suspending the boiler:
1. Consistently measure the position of the suspension of the boiler (according to the diagram with the dimensions)
2. Position the suspension bar on the required place and using a spirit level, balance the bar
3. Mark with a pencil the points where holes will be drilled
4. Remove the bar and using a O 10 mm drill, drill the necessary holes
5. Insert dowels into the hole and consequently secure it using the attached bolts
6. Suspend the boiler on the bar
7. Install piping for the exhaustion of burnt gases and the air supply. Fill the space between the piping and the hole in the
wall with fireproof material (remember to keep it dismountable for smoke collection).
In the case of installation on a wall with lower load-bearing capacity, it is recommended to consult the installation with
a service technician. Around the boiler, due to service inspection or potential service intervention, leave a manipulation area
so to be able to easily work with your hands around the boiler using standard hand held tools.
