Mark .. thanks for comment - struggling to get to bottom of this ... in
original Manual it stated 1 & 2 should be removed as a pair to set to
1000,000 Btu/h and when used with a Thermal store.
Also read elsewhere that if you remove 1 & 2 .. its sets to 100.000Btu/h
and turns off modulation

Are you sure that I should have jumper 1 in place ?

Looks like Explosive ignition issue may now be resolved (earth wire
harness issue) so left 4 in




also found this on-line ... has even different recommendation:

post#5 advises
set jumpers to: 1 in, 2 out, 3 in for Thermal stores

So far convinced 2 to and 4 in are correct, still unsure about 1 & 3
