wouldnt even do flue flow or spill, its arMy take on it.
I cannot remove coals as I cannot confirm they are correct position. I do not even know if they are all present. I also cannot confirm safe operation of appliance as do not know BP/gas rate figures.
Flue flow ok, spill good.
I must then leave it At-risk as I cannot confirm it is operating within safe limits.
imo
