Hints & Tips on Protectors

if a finished protector is of interest to you then i need to know the following details when ordering.

1) is it one of my water gauges ? if not maybe the glass nuts can modified to suit my plates, sizes can be given if required

2) water gauge size  7 mm ,  8 mm , 10 mm or 12 mm glass

3) when the water gauge is on the boiler in its fully working state you then need to measure the visible glass that can be seen between the glass nuts. (this dimension is very important because it is the one i work to for the length of the glass panels)

4) if your are making your own protector the pillars need to be 1 mm / 1.5 mm longer than the length of the glass panels.

5) on assembly put all 4 pillars and fasten to the bottom plate which is held in a bench vice , i then put a thin bead of silicon sealer on the bottom edge of the glass panels and then place in the grooves on the bottom plate now put the silicon on the top edge of glass you can now place the top plate over the whole lot and tighten the nuts , i now push the glass to the outside edge of the plates.

6) clean off any excess silicone and leave to set overnight

7) the silicon sealer now acts as a cushion to allow for expansion of the glass panels
