Installing a gas fire insert and cast iron fireplace
We have levelled the hearth and present drilled holes ready to attach Carron cast iron fireplace to wall. We now need someone to connect the Nu Flame Gas Insert to the existing capped supply. We also need someone to do a flue test. Do we require fire cement to seal the cast iron fireplace? Thanks
Expert Trade Answers
"Most fires will need a seal,, you are always better off ringing the manufacturer of the Fire, as a manufacturer instructions will always override anything from gas safe or any other platform"

"Refer to the manufacturer instructions. However most fires with a flue duct will require some sort of sealing with fire proof substance."
