1 Planning Manual Trench Heater GSK Fan-Assisted Convection

2 2 3 1 Trench Heater GSK Radial Fan-Assisted Convection Apart from the principle of natural convection, the trench heaters GSK work with a proportion of forced convection generated by a radial fan. In most cases, GSK serve for covering short-term remaining heat demands (quick heating) in cases where primary heat sources, as e. g. floor heating systems and air conditioners, cover the basic demand. With a corresponding power layout, they can also be used for the full heating of rooms. Convection Principle Areas of Application GSK Radial Fan-Assisted System Convector 1 The GSK consists of a two-chamber system. The air blown in is trapped in the lower chamber. The patented air guide system of the GSK devices guides a controlled flow of air into this chamber. 2 An airflow is injected, aspiring the cold air (cold-air drop) which is falling down, thus accelerating the natural convection. The air coming from the fan is distributed on a System Trough length of up to 5000 mm. 3 Heated air creates a barrier against cold drafts and heats the room. 3 2 The GSK can be applied in all situations where a fogging or the formation of condensed water could be possible, or in areas requiring quick heating. GSKs are predominantly used in screed areas as well as in raised floors in front of full height glazing facades in modern, transparent architectures. Examples: Representative living areas Winter gardens Restaurants Foyers, reception halls Shop rooms Exposition rooms Shop windows Office and administration buildings, as well as Areas with quick heat demand 1

6 1.2 Designer Grille Product Presentation Surfaces With the Designer Grille, Möhlenhoff offers a creative cover grille solution for System Convectors in first-class quality. Distinctive mark of the Designer Grille: the elegant appearance due to narrow, rounded bar profiles in all surface variants. The omission of bar joints gives the Möhlenhoff grille its characteristic, sophisticated appearance. The Designer Grille is offered in the versions Linear Grille, and Roll-up Grille. Both Designer Grille versions are built in the same constructive way. Designer Roll-Up Grille In front of full height glazing facades, the Designer Roll-Up Grille is the optical change-over between floor covering and the facade itself producing a soft, floating transition zone. Designer Linear Grille The Designer Linear Grille is characterised by a parallel arrangement of the bars. This produces a clear optical border between floor area and facade. Apart from optimum functionality, it is after all the extensive and unique Möhlenhoff finishing options which sets new scales with respect to design possibilities. For the individual expression, Designer Grilles are available in different anodised shades, stainless steel finish, a RAL colour selection and in high-quality decors. Anodised shades The surface finishing by anodisation emphasises the highvalue character of the bar material. Apart from the standard anodised shades, all further anodised colours are available on request. Stainless steel finish The Designer Grille in stainless steel finish sets aesthetic courses. The anodisation of the aluminium bar profiles allows to produce a very realistic stainless steel finish. RAL All colours of the RAL system can be realised, allowing a full implementation of individual design requirements. Product Innovation High safety The rounded bar profiles of the grille allow safe step-on. The rubber bearing makes the Designer Grille non-skid. The integrated cutting edge cover of the grille protects the user against injuries during installation, cleaning, or maintenance work. High strength The Designer Grille is marked by high abrasion resistance. It has been tested for chemical, thermal, mechanical and ultraviolet resistance, according to the most stringent criteria. Stainless Aluminium profile bars ensure a high stability, are resistant against ultraviolet light and humidity, do not rust, nor warp, nor change their colour. Decors A multitude of wood and stone surface decors are available for an exclusive room design. All aluminium profiles are refined with individual, natural decors in a high-quality and enduring way. Möhlenhoff is well renowned for the production of decors which are an exact copy of the original floor covering. Transition areas from the floor covering to the cover grille can be realised as if cut of the same cloth. Therefore, we use a customer-provided sample for the production of all decors! Exclusive requirements to a harmonic overall solution in interior areas can be fulfilled by means of a perfect imitation of the decors. Soundlessness The rubberized underside on the bottom insulates step-on noises on the profile edge of the System Convector. Flexibility The Möhlenhoff Designer Grille is equipped with exchangeable bars. The Roll-Up Grille can be cut to length on site. Easy cleaning The Designer Grille is easy to maintain. The smooth surface offers protection against dust and dirt. You can find detailed information on surface design in our Designer Grille brochure. You can find technical information in the Designer Grille Planning Manual. 6 Radial Fan-Assisted System Convector GSK

We are always at your disposition for questions. 1 Blinding layer mm 2 Concrete floor 3 Impact noise insulation 7 8 min 50 mm Heat insulation 5 Separating layer 6 Screed 7 Exterior window 8 Curtain (may not hang above the trench heater) Trench Heater GSK 10 Floor covering (e. g. parquet, title marble, carpet) 11 Rug (may not cover the trench 2 heater) 1 1. Notes on planning phase and installation preparation Measuring on site in order to consider constructional tolerances. Under consideration of the installation requirements and standards on site (DIN and VDI 2035), a trench heater is installed in the screed area. For a complete isolation of the cold air stream in front of glazing facade, a screed convector must cover the entire length of the glazing. The trench heater must always be accessible for possible maintenance work. Pre-lay electric lines in empty pipes to the connection side. Provide an empty tube if a remote control is used. With respect to the distance from the System Convector to the window, possibly existing curtains must be considered. They must not hang over the trench heater. Only after the termination of all constructive work may the installation cover be removed permanently; until then, the Designer Roll-Up Grille must be stored in a safe way. 2. Positioning and Alignment The visible upper surface of the installation cover is the finished dimension for the floor finish (floor coverings as e. g. parquet, title marble, carpet). The trench heater can be aligned according to the height of the finished floor installed later. Interior (e. g. on the window side) and exterior (e. g. on the room side) adjustment blocks are available for this. The latter must be fixed to the raw floor, if necessary, in order avoid a floating of the System Convector. For higher constructive heights, a loadable, impact sound absorbing support must be provided below the trench heater. 8 Radial Fan-Assisted System Convector GSK

9 3. Notes on hollow floors (raised floors) A free-standing installation for full step-on ablility must be possible in raised floors. See page 35. The trench heater must be fixed in the raw floor using the adjustment blocks in order to avoid sliding. 6. Screed Use of noise insulation for borders: Screeds and floor coverings, parquet flooring in particular, may apply pressure to a floor paving trench heater due to their thermal behaviour. Take countermeasures, as e. g. expansion joints. Hot Screed: Special measures must be taken with respect to special screed types, e. g. hot screed (240 C), to ensure that the System Convector is never exposed to a temperature of more than 120 C. Interior adjustment blocks JBI 7. Resources The water composition must be arranged according to DIN "Heating installations with central water heating installation and VDI 2035 "Prevention of damage in warm water heating installations". Exterior adjustment blocks JBA 4. Line installation of System Convectors The trench heaters are connected with system connectors (see page 35). Conclusively proceed as described under "2. Positioning and Alignment". 8. After the termination of the construction work Please insert the Designer Grille only after the end of all working measures. Remove the installation cover Roll out the roll grille beside the trench heater and cut the corresponding length with a knife. Linear grilles are custom-designed. 9. Maintenance Notes on maintenance see page Connection of the trench heater In standard cases, the pipe are connected on the left side with viewing direction towards the window (see point mark on the installation cover) The electric connection is performed according to the supplied installation instructions of the respective System Convector model. On pages 26 ff you can find further notes on the electric connection in stand-alone or parallel operation. Radial Fan-Assisted System Convector GSK 9

36 3.7 Maintenance and Care Recommendations The following notes serve for a general preliminary information during the planning phase. The GSK installation instructions offers complete information as well as safety notes for the specialist staff. Cleaning the Designer Grille 1. Dry cleaning: Vacuum the Designer Grille at regular cleaning intervals during normal cleaning. 2. Wet cleaning: Open existing grille fixings, roll up the grille without bending it excessively. The DR is dishwasher safe even up to a temperature of 60 C with normal (non-industrial strength) dishwasher detergent. After washing and drying, the grille can be replaced on the convector trough and re-secured. Remove the linear grille from the trench heater and lay it down to an appropriate place. For cleaning we recommend commercial household cleaners and a soft washing brush (e. g. car accessories). After washing and drying, the grille can be reinserted onto the trough. Cleaning the System Convector 3. Cleaning the filter fleece As a standard, Möhlenhoff radial fan-assisted trench heater are equipped with a filter fleece above the fans. Take out the filter fleece and beat it for cleaning. If strongly contaminated, the fleece can also be washed by hand with clear water; allow it to dry afterwards. After that, re-insert the Designer Grille and the filter fleece, if necessary. 3. Clean and Check the Blower / Fan Remove the cover grille and the fleece filter. Make sure there are no foreign objects in the blower/fan, remove any if necessary. Turn the fan by hand. If there is damage, inform a specialist. The blower/fan area can be vacuumed (a soft brush can be helpful). Lay the filter fleece and cover grille back in place when finished. 4. Examination and cleaning of the air guides Remove the Designer Grille and the filter fleece, if necessary. We recommend the use of a dry duster cloth of feather duster for cleaning the air guide areas accessible with the hands. Areas with difficult access can be vacuum-cleaned (a soft brush can support the cleaning process). Adhering contamination can be removed with a damp cloth, if necessary. After that, reinsert the Designer Grille and the filter fleece, if necessary. 5. Cleaning the heat exchanger Remove the Designer Grille. To clean the hand-accessible area of the heat exchanger, we recommend a dry dust cloth or broom. Hard to reach places can be cleaned with a vacuum cleaner equipped with a soft brush nozzle or a soft brush. Replace the filter, if needed, and re-secure the Designer Grille.
