I have a 800 Home Fires freestanding wall unit with two 3.5m flue pipes. The second flue pipe together with the rotating cowl and slip-on base have been galvanized for weatherproofing.
The fireplace is the deep unit and comes with an protection grid .
Still installed and would need time to remove for you.
New this lot would cost nearly R9 000.00 so my price is 50% off the new.
