ENCLOSING THE OVEN

Your Mugnaini Oven is now ready for the final step of the construction process – which relies entirely 
on your level of creativity and desired architectural effect.  The oven enclosure protects the oven from 
atmospheric moisture, supplies ventilation to the oven (so that condensation does not occur within the 
compartment), and retains the insulating materials placed over and around the oven crown itself.

Chimney pipe length will vary depending on oven enclosure design. Consider this when determining 
your oven roof height. See page 19 & 20 for chimney pipe information.
