Highrise, Graduate and Opera Aluminium Radiators - General Specifications and Information
General
The Highrise, Graduate and Opera radiator ranges represent amongst the most
stylish and efficient sectional aluminium radiator designs on the market.
Although more costly that steel radiators, they are more efficient which means
that for a given rated heat output these aluminium sectional radiators will
typically take up about half of the wall space compared to the equivalent steel
models. This makes them an ideal choice if you require radiators that are
relatively unobtrusive, efficient and stylish. Sectional radiators come as a
easy to assemble kit complete with the connection fittings and tools required to
assemble the radiator.

Please refer to the handling guidelines provided with this product. This
contains important information about the safe handling of these radiators to
minimise risk and damage.
Assembly Advice
Large size
radiators may be supplied in sectional form for ease of handling. If this is the
case then please refer to the site assembly instructions supplied separately.
Water Treatment
These products are
for use on closed heating systems only; they are not suitable for installation
on secondary HWS circuits. On completion of the installation the entire system
MUST be thoroughly cleaned and flushed to remove debris/flux residues etc. If a
chemical cleaner is used, it must be thoroughly flushed from the system.
Following this, the system MUST be dosed with a good quality water treatment to
prevent corrosion.
Note:
Failure to observe these requirements will render the product guarantee void.
Corrosion inhibitor must be used in accordance with the manufacturer's
instructions and recommendations and should take into account the particular
metals within the system.

The external
surface of the radiator should be cleaned with mild detergent. No solvents or
abrasives should be used

supplied in primer finish they can be covered with a variety of paint types
including water-based, oil-based, cellulose, 2-pack acrylic and stove enamel.
These radiators may have been supplied factory painted in your choice of colour.
If so, no further painting or surface treatment is necessary or recommended.
Always consult the paint manufacturer's instructions.
Operating Pressure
These radiators are
designed to operate at a system maximum pressure of 6 bar.

Bushes & Washers Each radiator is supplied with a bush & washers for each of the 4 connections. A) Two 1/2" or 3/4" BSP threaded bushes & washers for connecting radiator valves B) One bush and washer for the air vent C) One blank bush & washer The
bushes and brackets are supplied in a blister pack and must be fitted to the
radiators before installing. |
|
Use only the sealing rings
supplied for sealing the bushes, air vents and plugs. No thread sealant paste or
tape may be used on the thread or bush which mates into the radiator. When
fitting radiator valves to the left-hand threaded bushes; hold the bushes firmly
with a spanner. This will ensure that the bushes are not allowed to rotate and
become loosened, thereby preventing the risk of leaking.
It is recommended that the threaded tail pieces of radiator valves or other pipe
fittings that are screwed into the bushes are sealed with PTFE thread sealing
tape. Sealing compound can also be used but great care must be taken to ensure
that the sealing compound makes no contact with any of the sealing rings.

Assembly Guide - Aluminium
Radiators
While these
instructions show the Graduate range of radiators, the procedure remains the
same for the opera and Highrise styles.
|
|
|
|
Use a perfectly flat area for assembly and ensure that all machined faces and internal threads are clean. Each section has right-handed connections at one end and left-handed ones at the other. Nipples have one end left handed and one right handed. Study the orientation of connections carefully before assembly. There are 2 joints to be made for each pair of sections. Each of these requires 1 connection nipple and 1 gasket. A nipple key and tommy bar are required to rotate and tighten the connections |
Screw a pair of nipples into one end of the radiator. Only screw in by one turn, do NOT screw in fully. Place a gasket approximately at the mid-point of each nipple. Do not use any jointing paste or tape (PTFE or similar) to the gasket, nipple threads or radiator.

Carefully slide the second section next to these nipples, taking care that the thread connections are correct. Place the nipple key over the top of the radiator so the head is in line with the nipples to be turned. Mark the key so that when it is inserted the head will engage inside the nipple. Slide the key in from the open end of the waterway until it engages into the nipple that needs tightening. Check the end of the key has fully engaged in the internal lugs inside the nipple |
Rotate the nipple using the nipple key, so that it pulls the 2 sections together. At this stage only rotate the nipple by one turn. Repeat with the other nipple. Repeat the above, alternating so that both sections are pulled gradually together and ensuring they are kept parallel. Finally, tighten the joints so the gaskets are firmly compressed. A tightening torque of 100 Ibf-ft must be applied. |
