The Variomodular pipe should not be stored outdoors. The interaction of the air's oxygen with UV rays damages the pipes. Normal temporary storage on the construction site for a few days is permissible. 1.4 Heating elements The heating elements are delivered packaged in boxes with a length of 2.5 m. They must be protected against damage or unintentional bending of the louvres mm 40 mm 40 mm 56 mm 78 mm ø 18 mm 0,5 mm Copper pipe wall thickness Standard heating element 2500 mm 40 mm 40 mm 35 mm 78 mm ø 18 mm 0,5 mm Copper pipe wall thickness Mini heating element

Skirting heating types INDIVIDUAL HEATING 3.4 Manifold system with the pre-insulated Variomodular pipe 16x2/Alu0.25 For installations with manifold systems, first lay the pre-insulated Variomodular pipes from the manifold to the skirting heating and back, and then connect them to the manifold via a screw fitting. There must not be any kinks in Variomodular pipes when laying them. The Variomodular pipe should be routed endlessly (i.e. without additional connection points) from the manifold to the skirting heating. The pipe is positioned near the skirting heating with the installation bracket. Electronic room thermostats and servomotors are used to control the room temperature.

Screw the lower and one of the two upper screws into the positions marked previously, but not fully (allow space of approx. 5 mm). 4. Fit the bracket to the screws Fit the missing screw, align the bracket and fasten (tighten all screws).

Fitting the heating elements 5.1 Inserting the heating elements Lay the heating elements parallel to the wall and push the aluminium plates on the brackets to one side with an open-end wrench (size 21), for example. Insert the heating element The heating elements are cut to length according to the diagram using pipe cutters. Sections are soldered to one another or pressfit (use approval for the Viega Profipress system > support sleeves!) Ensure that the installation position of the heating element is correct in accordance with the prescribed types (see Chap. 3). 5.2 Securing the heating elements Secure the heating element using the clips The clip of the respective type is pushed down at the points marked with an arrow, and then latched into position using the thumb.

"DISTRIBUTION and CONTROL" Details regarding the system and heating circuit pipes and the room temperature control are provided in the "DISTRIBUTION and CONTROL" planning and installation manual pipe system In the 2-pipe system, the skirting heating is piped in accordance with the laying diagram using copper pipes, for example. The flow valve is installed with integrated deaeration in the flow side and the return valve is installed in the return side.

11 Installation manual 6. Hydraulic connection of the heating elements Page 11 Soldering the copper piping Before soldering, prepare a cover to protect the floor and wall from flames. Clean the pipes and fittings at the solder contact points with a cleaning cloth and inner brush. Apply solder paste evenly to one part. Join the two contact points and solder them. It is important that the soldering point is kept clear of dirt particles such as masonry dust etc. Tip for piping: If necessary (old building with finished floors etc.), additional uninsulated pipes to max. 18 mm external diameter can also be held in the brackets. Typ Ia Typ IIa Typ IIIa Deaeration The individual skirting heating systems are deaerated via the flow valves with integrated manual deaeration systems. The deaeration elbow is inserted in the return for valves without integrated deaeration systems. Deaeration elbow Flow valve The flow valve with integrated deaeration is available in left, right or continuous versions. On delivery, there is a protective plastic cap on the valve spindle. This allows the valve to be opened or closed without a valve head. Before mounting the valve head or the handwheel, the protective plastic cap is removed.

14 Page Cladding INDIVIDUAL HEATING 7. Cladding If the required skirting heating cladding is not mounted immediately, protect the mounted heating elements using their packaging boxes, for example (cut slits in the box, pass the bracket catches through). This effectively protects the heating elements from damage. 7.1 Delta cladding Fit the Delta at the bottom near the tension spring and click it into place at the top. Delta cladding which has been clicked into place. If uneven walls cause problems when snapping the upper edge into place, loosen the upper bracket screws. After locking the cladding into place, the screws can then be tightened again through the upper front hot air slit opening To remove the cladding, first pull it out at the bottom and lift it out upwards. Connections The connecting elements are clipped in, inner corners, outer corners and the end caps on the left and right are fastened subsequently using the enclosed screws to the front cladding (do not forget to drill). Inside corner 90 Outside corner 90 Connecting elements End cap left End cap right The formed parts are attached with the supplied screws. Use the Variotherm paint pen to paint the screw heads after mounting. Round hole punch For the flow valves, punch a hole into the Delta cladding in the axis of the valve head using the appropriate round hole punch. The thermostat head will later protrude through this hole. Hole diameter required: ø 40 mm for mini skirting heating system, ø 55 mm for Ia, IIa + IIIa, and valves with servomotors Example: Delta mini skirting heating system

If the wooden skirting is mounted further from the floor (e.g. due to wall-mounted pipes), you must still comply with the air vent spacing (extend cladding further down) For cladding of the Classic skirting heating provided by the customer, each bracket includes a mounting plate and mounting base with fastening screws (see also Chap. 5.1). Virtually any wood is suitable as wooden cladding. It should be torsion free and dry (e.g. 3-layer board). Push the mounting base into the bracket and transfer the outline to the upper cladding. Screw the mounting base onto the upper cladding The upper cladding can now be pushed into place. For the front cladding, the mounting plate is secured after adaptation to the brackets Attach the front cladding to the bottom spring and click it into the catch. Simple mounting brackets are used for end connections. Drill a hole in the cladding in the axis of the valve head for the flow valves.

Leak-tightness test & commissioning Construction project: Building owner/ Occupant: Client: Heating installation technician: Architect: Other: Leak-tightness test The Variotherm skirting heating system circuits are to be tested for leak-tightness using a water pressure test after they have been laid. The test pressure should be twice the operating pressure (at least 6 bar). If there is a risk of freezing, appropriate measures should be taken, e.g. use of antifreeze and controlling the building s temperature. > Skirting heating incl. cladding, connection and piping completed on: > Pressure test started on: > Pressure test finished on: > The system water was treated (e.g. per ÖNORM H5195-1) Yes No > Antifreeze was added to the system water Yes No > Heating started on: Approval: Building owner/occupant/client Construction management/architect Heating installation technician Commissioning The flow and return valves or the heating circuit shut-offs on the manifold must be opened. The entire system is to be deaerated thoroughly. The circulation pump may be switched on after deaeration. After commissioning, the Variotherm skirting heating system can be considered maintenance-free. (Subject to technical modifications without notice.)
