T6 RADIATOR

Technical information

The T6-CENTRALLY CONNECTED RADIATOR is - with its welded in set of T-shaped valves - suitable for double-pipe installations as well as single-pipeinstallations, using a single-pipe manifold. Additionally to the central connection from the bottom, the sophisticated design makes possible other connections used at compact radiators, such as the single-sided and two-sided connection.

Radiators are delivered ready for double-pipe installation and with a factory-adjusted k_v-setting, appropriate to the radiator output.

For district heating installations with a big difference between water supply and return temperature, a valve unit that allows a precise and stepless adjustment is available on request.

Connection modes - double-pipe system

A) Single-sided connection
B) Connection both sides
C) Connection on top (Warning: Lower performance)

Caution:
When using the T6-CENTRALLY CONNECTED RADIATOR as a compact radiator, the 3/4“ screwing caps made of plastic have to be replaced by nickel-plated brass caps (accessory). Available under the item number: AZ0PL000C0002000. Additionally the plastic part of the special vent plug has to be removed.

Of course it is also possible to change the pre-adjusted valve setting when the equipment is operating at pressure.

Double-pipe operation - Adjustment tips for built-in valve

Setting instructions: VOGEL&NOOT valve radiators are factory-fitted for double-pipe installations. Each individual radiator is fitted with a pre-adjusted valve insert, appropriate to the radiator output. The preset kv-value is also marked in colour on the front surface.Please note: Should customised adjustments be required, the pre-set kv-values can be altered as needed. Swapping the right-hand side built-in valve to the left-hand side is no problem at all at any time. Radiator are delivered with protective caps. After removing the protective cap (pos. A) the following thermostat heads can be fitted directly to the builtin valve (pos. B): “RA 2000”, “RAW” by Danfoss, “VK” by Heimeier, “D” by Herz, “thera DA” by MNG and “UNI XD” by Oventrop.

After removing the protective cap (item A) the following thermostat heads can be installed directly onto the built-in valve (item B): „RA 2000“ and „RAW“ by Danfoss, „VK“ by Heimeier, „theraDA“ by MNG, as well as „UNI XD“ by Oventrop.Caution: During the installation take care that the return element (2) has been installed at the water return, and the supply element (1) at the water supply. Changing the built-in valve from the right- to the left-hand side can easily be done at any time.

T6-CENTRALLY CONNECTED RADIATOR

Material & Surface
Made of cold-rolled sheet steel, in accordance with EN 442-1; , with a stylish and robust fluting with ribs at 40mm intervals; undercoating in accordance with DIN 55900 part 1, stoved at 190° C; finished with electrostatic powder coating, in accordance with DIN 55900 part 2, in standard colour 9016; stoved at an object temperature of 210° C.

Equipment
Fitted with an integrated T-valve set; designed for double-pipe and single-pipe systems with a single-pipe manifold; factory-installed built-in valve with pre-set kV-value adjusted to heat output; if needed, adjustable in the range 0.13 to 0.72. With single-pipe systems, the radiator proportion can be set from 30% to 50%. All models are fitted with a protective cap for the built-in valve, welded suspension brackets on the back, a removable top cover and two closed side panels, a drain plug, a pivoting special vent plug and a dummy plug, all of them sealed; the cover system complies with the former BAGUV regulations.

Assembly
Complete pre-installation fitting is possible using the fitting templates (external thread 3⁄4“); flush and hydrostatic test using the flush device (accessory); also suitable for connection as a compact radiator (one-sided or two-sided); standardised wall clearance for all multi-layer radiators (with a special angle-fishplate also for single-layer radiators); disassembling and assembling of the top cover by means of decor-clips. Verification of heat emission in accordance with EN 442; constant monitoring of the production process in accordance with EN-ISO 9001; triple packed (cardboard packaging, edge protection, shrink foil). Suitable for manual operation as well as thermostat operation. Connection possibilities for copper, steel, plastics or alloy pipes.

Connection
4 x internal thread G 1⁄2“ and 2 x external thread G 3⁄4 “, at bottom centre. Thermostatic valve (factory-sealed at top right) subsequently convertible to the left, without having to turn the radiator and without crossing supply and return.
