The back boiler is sooted up and is extremely dangerous.The flueways will be carbonned up and a complete stripdown will be needed.Do not attempt to use it as the flames could burn thro the wiring that feeds power to the boiler causing even more damage.Get someone out asap.Transco will only make safe,so ring someone Corgi Regd as quick as you can before the snow comes.
