1. Decide where the centre of your radiator will be and then decide your preferred overall height from the floor to the top of your FARAL aluminium radiator then put a small mark on the wall.

2. Measure 42mm down from that mark on the wall and make another mark.

3. Find a spirit level and from the second lower mark put a horizontal line equal distance either side of the centre line across the wall just less than the width of the radiator being installed.

4. The top white rod type brackets will be fixed along this line.

6. Each white rod type bracket will pass between the top of two sections at the back of the radiator from which the radiator will hang.

7. The distance the top brackets must be fixed is in multiple lengths of 80mm so they pass exactly between the radiator sections.

e.g If a top bracket distance of 10 sections is required to hang a 16 section radiator then 10 x 80mm= 800mm centre to centre of the top brackets or 400mm either side of the centre of the radiator.


Any tall radiator that is usually over one-metre-high that is being installed with BOE or Bottom Opposite End connections will either have a flow diverter already fitted or as with the Longo one will need to be installed on the flow inlet just prior to fitting the corner flow in tapping bush, fitting the flow diverter literally takes five seconds.

When using BOE or Bottom Opposite End connections on a tall radiator the flow of water will always take the least line of resistance across the bottom of the radiator and mostly bypass the top half making it cooler and inefficient. The flow diverter corrects the direction of flow from flowing along the bottom of the tall radiator and out to diverting the flow of water straight up, across and down the radiator.

The flow diverter is required to push the hot water up to the top of the radiator as it enters allowing the water to then cascade from the top down giving an equal distribution of hot water across the radiator from top to bottom maximising the thermal efficiency of the tall Longo radiator.

It is important that the flow diverter is fitted or situated as close to the bottom flow inlet side of any tall radiator, if the diverter is incorrectly fitted or situated on the flow out of the radiator it will restrict the water leaving the radiator and effect the efficiency of the radiator.

The Longo radiator requires the flow diverter inserting and pushing firmly into the centre of the first nipple on the bottom flow inlet into the radiator.

The diverter is not required if the connections are configured as TBOE

Top Bottom Opposite Ends as the water will naturally flow across the top of the radiator and evenly cascade down from the top leaving the radiator from the bottom corner.
