]316 is not just for gas and is perfectly fine for solid fuel.
Its ok for smokeless coal and occasional smokeless fuel use only. Burning man made smokeless fuel on more than an occasional basis the fumes contan sulpher gas which is highly corrosive, it will go through 316 in about 18 months, in that situation just fit 904.
You don't actually need a register plate if your fitting a liner.
So what stops the heat rising up the chimney ?, without a register plate you might as well leave it as an open fire.
There for open chimneys to stop hot ash falling back down the chimney. With a liner you use one just to stop the usual crap coming down like rain. The stove fitters manual online is free and gives you step by step guide to fitting a stove. The Stove Fitter's Manual | How to fit a wood burning stove
The chap from building control who signed my last one off was an ex brick layer who told me he knew nothing about stove fitting. He said use common sense and they have been fitting them for more years than he had been alive without regulations and it was a waste of time him looking.
Not surprised to be honest , I have had a building inspector sign off a self install with a cap on the top that you use to close off a disused chimney.
Vermiculite is for insulation of the liner in a cold chimney, ie a chimney that runs up the outside of a house to stop condensation in the chimney. The flue liner, cowl and flue adaptor can be had for less than £200. (6") 316/316 Solid Fuel/Multi Fuel Flue Liner FlexiFlueDirect.com
If your house burns down and its fitted correctly your insurance will have to pay out.
The insurer passes the claim to a loss adjuster, its his job to get the insurer out of paying. No sign off and no insurance. Dont forget that the sign off is registered at your local town hall so you cant say the cert went up in the fire.
If it's been fitted by a professional incorrectly and your house burns down, your insurance won't pay out.
Your insurer would pay out in that situation but would then be suing the installer.
It's easy to do and do it properly and you won't have any issues.
Agreed, but get it signed off.
