How do you mark out clips for boilers?

[ApprenticeTom]

Just wanting to see the different ways people do it when accuracy is involved

thanks!

Spirit level usually or sometimes the Dewalt lazer level if its to hand.

That's cool, what if the valves are a good 6 inch away from the wall? Just eye it up with a spirit level then?

(if close to a wall)

check wall is straight and measure to centre of each valve and mark on wall

(if not close to wall)

use a reference on the jig and measure from that or stick a bit of 15/22mm in the fitting and mark center

A pencil mark just below boiler, exactly centre
Most templates will have dimensions from centre line of boiler to supply pipes

As above I usually use the paper template as a reference and mark the wall from their, although I usually don't clip too close to the boiler to allow slight movement in the pipe work for future maintenance

i strike a line center drill flue hang boiler then measure of the center line either way for each pipe

i strike a line center drill flue hang boiler strike two horizotal ines where i want the line of clips then measure of the center line either way for each pipe

Depends on wether existing or new...

If installing new then check where joists are (if running pipes) and position boiler central between joists where possible... (makes life easier) after finding centre point then use laser level to mark a centre line and then mark where clips are going from that. After that I get the mounting template out and mark the flue centre, normally by hammering a nail into plasterboard as this pierces the paper and also acts as a nice pilot for your core bit.

If replacing an existing then its a toss up between what is more convenient, getting the flue through the same hole, or wether the pipework is exactly the same and redoing the core will be easier.


Best thing I ever bought was the laser level.. they rarely lie.
