Heater foam?

[Pete 21]

Hi All,
The bottom vent flap on my heater had some type of thin foam pad that had deteriorated to basically a dirty fluff. I’ve stripped it out as it can’t have been serving any purpose other than putting lumpy dust into the air. I’ve never come across it in parts catalogue’s, does anyone know what it’s made of?

Replace the sponge with neoprene sponge.
Different thicknesses maybe required.

The dirty fluff is horrible, best not to breathe it in I decided ... I had had great results using the self-adhesive closed-cell black sponge profiles from Woolies https://www.woolies-trim.co.uk/ for all the seals in the heater.

This is described as "virtually non-absorbant with good resistance to weather aging and oil contamination. Self extinguishing when the source of ignition is removed". I found that it has the right amount of springiness ( technical term ! ) to get a good seal.

Hi Philip

Which sponge did you use?

Hi Bruce

It was was some time ago now, but tor the bottom vent flap I think it was probably Part No: 300-1/8-3, which is a strip 1/8 inch thick and 3 inches wide - I may have had to use two pieces side by side. I used various other size of the same material for the other flap and seals. It worked out well, good luck with yours.

I used eBay neoprene sponge… ordered various thicknesses.

Recall using evo stick contact adhesive as an extra precaution.

Its a big job.

Biggest lesson learnt was to mark up the spindles to levers orientation.

Also made spindle bearings in brass & sweated into the sides.

Original spindles to panels had no bushings at all!

Well done - I thought about it but not until I had already had the umpteen pieces of metalwork powder coated, so didn't do it. Its pretty shoddy design not to have had some sort of spindle bearing, but I took some of the rattles out by using various thicknesses of nylon washer on the spindles when I put the parts back together.
