Thanks for the responses, it's looking like advice should have been sought before this happened.
Hindsight is such a wonderful thing but yes it always pays to research before you embark on something you may be unfamiliar with; there are all sorts of things that can catch you out with plastering & using the wrong materials around fires & tiling is another aspect altogether. Don’t be too hard on yourself, there are many “tradesmen” who seem to be completely unaware of even the basics let alone the stuff I know about, that’s why we get a constant stream of folks on this forum & in the media looking for advice after expensive failures.
Hmm, the stove is going to be about about 200mm away from the panels, so your right the temperatures may well exceed that once the stove is going, but is hard to tell.
I would say it’s a stone bonk certainty; I’ve measured temperatures into the high 90’s in the area & chimney breast around a multi-fuel stove & it was personal experience of failure that made me aware of what I now know & how I deal with them.
Got a heater inside will see if the patches dry out. Not sure if trying to remove the panels is even a sensible option, they are about a metre square, so can see them cracking into bits..?
Personally I would advise you remove them now while you easily can; being evaporative cure, the filler will still not be fully cured & it’s completely unsuitable due to the temperature restriction anyway.
The size of the granite panels can also be a problem around high heat output stoves. Hearths & surrounds for solid fuel appliances are rarely one piece, they are made up in sections (I usually use 600 x 300 x 10mm granite/stone tiles). If you have too large a tile/panel (& IMO one metre square is too large) they can crack due to different expansion rates caused by variation in temperature between the hottest & coolest parts of the panel.
If you give some details & even pics about the size the fire, details of the opening etc & what you want to achieve, I can give you detailed advice about the best way to proceed.
I would also advise you read through my standard stove blurb below, there may be further revelations awaiting you in the links;

As this comes up so often, I’ve put together this generic post; read the links but not all may apply to you.
You can DIY a stove install but you need to understand the Building Regs (which changed in October 2010), submit a Building Notice & pay a fee. Your LABC will inspect &, assuming everything is OK, issue a compliance certificate; the BI may want to witness smoke & spillage tests. No compliance certificate may lead to difficulties when you come to sell your property; if cannot produce a compliance certificate in the event of a problem, your insurance company may invalidate your policy & reject any claim.
Lots of archive threads on this, & other things you have to watch out for, here a few links for you to read:

Also get at least 3 quotes from local independent HETAS installers:

You might be pleasantly surprised & you should ask yourself if you really want all the hassle & risk getting it wrong; climbing onto the roof with an 8M stainless steel snake on your back is not for the feint hearted!
