Insert 6 - Metalfire Optimum - enclosure partly demolition

The old stove needs removing to make room for the new one. Very important: what size pipe is the chimney channel? The Metalfire needs an 18 cm diameter flue pipe, the existing channel is a 20 cm galvanized pipe. Two problems: 20 cm is too wide, and galvanized steel is not suitable as a flue pipe.

The engineer hopes there is a second tube inside this 20 cm one, that is 18 cm. 15 cm would be trouble. (15, 18 and 20 are standard sizes)

As it was...

Roasting Papaya and Tex

Take the front of the enclosure off:





Removed the old stove, there is a raised platform there, ladrillo and cement:


Also note: no insulation whatsoever.  That is bad. Walls and pillars need to be protected from a stove's heat.

Brittle cement, pebbles, and thus a hole in the floor:


The chimney flue pipe is a single 20 cm pipe, galvanized steel. Rubbish!

The good news is that there is no 15 cm channel in there, so we can just put a new 18 cm flue pipe in there, Engineer Jansen already is assembling a shopping list for 18 cm wide inox pipe materials. 

Also, the inside of the enclosure needs insulating the walls. Rockwool Firerock seems nice, semi-rigid rockwool panels 100x60x3cm. Comes in boxes of 10, for ca. €150. But more on that later.


Fill the gap in the floor with cement for an even level floor:

Leftover bits:





Oooh!
