Step 1 – Dressing The Radiator

 

Before you can start installing your new radiator you will have to dress it to make sure it’s ready to go.

So first thing’s first – take your radiator valve and apply PTFE tape to the tail of the valve.

Wrap it around clockwise about 17 times. Do this for both valves and remove the radiator bung.

Step 2 – Attach The Air Vents

 

Screw in the air vents, being careful not to over-tighten too much – you don’t want to damage the O-ring.

Step 3 – Find The Centre Of The Brackets

 

When you have marked your centre-point, you will then have to measure the centre between the left and right brackets.

It is best to do this with the radiator led flat on its back.

Step 4 – Measure Between The Brackets

 

When you have measured the centre, you will need to work out the height of your radiator.

You can do this by measuring from the top of the top bracket to the top of the bottom bracket. Again, it is best to do this with the radiator flat on its back.

Step 9 – Begin To Solder Pipework

 

You are now ready to solder. Using a blowtorch, heat the join until it is hot enough for the solder to melt.

When applying the solder you must ensure that it runs around the whole fitting. Allow the solder to set and then using a wet cloth wipe away any flux residue and clean with wire wool.

Step 10 – Fit The Valves

 

Using your adjustable spanner, affix your valves to the radiator on both sides.

Once you are happy that the radiator and the pipework are sound, fire up your boiler and check that your radiator is warming up.

If it is you can then put your floorboards and carpet back down.
