Installation - Mark GS+ 35 Technisches Handbuch

Installation. In Belgium, the wall air heater must be installed in accordance with Belgian standard
EN
NBN D51-003.
Gas supply and connection
Before installation, check that the local distribution conditions, gas type and pressure and the
current adjustment of the appliance all match. An approved gas stop cock must be fitted to the inner
pipeline.
Flue gas route
Combustion air supply pipelines and combustion gas exhaust ducts should have as few bends as
possible; in general, flow resistance should be kept to a minimum and in all cases, the diameter
should be constant along the entire length. The exhaust duct may not rest on the heater, but should
be suspended efficiently! If the flue gas exhaust duct passes along or through combustible walls or
floors, the duct must be sufficiently far away from the combustible material to prevent fire.
1.4 Think of your safety
If you smell gas, you must not under any circumstances:
– Ignite an appliance
– Touch electrical switches or telephone from the area in question
Take the following action:
– Switch off the gas and electricity
– Activate the operational emergency plan
– Evacuate the building if necessary

2.0 Installation

2.1 Positioning the appliance
After unpacking, check the appliance for damage. Check that the information relating to the type/
model and the electrical voltage is correct. Place the appliance and any accessories on a sufficiently
solid structure [2 & 3], taking into account the minimum free space required [1].
For GS+ you should use the four M10-sized suspension points [21]. GC+ devices provided with
a support frame should, when hung up, always be mounted to the support frame, see the detail in
picture [22]. Never mount to the M10-sized suspension points, as these are not intended for this
purpose. Also, remove the transport feet of the frame when the device is to be hung, see picture
[23]. Frames can be connected by means of the connection pieces as shown in picture [24].
2.2 Positioning the flue gas exhaust system and air supply
The flue systems must be constructed according to CEN-TR 1749:2014. The extension pipes
should be carried out in parallel. Preferably use stainless steel flue outlet pipes. The air intake pipes
may be carried out in thin aluminium according to NEN-EN 1856-1:2009 or in PP according to
NEN-EN 14471:2005. The discharge material must have a positive assessment for use with gas-
fired appliances. This positive assessment must be issued by an inspection agency with ISO 17025
accreditation.
We recommend that you involve the manufacturer for supply and discharge material. These meet
the requirements. It is not allowed to use various types of supply and discharge material together.
See table [4] for the correct connection size to the unit and placement. The drainage construction
C63 must comply with the NEN-EN 1865-1:2009 and be calculated in accordance with EN 13384-
1&2.
