PRECAUTIONS
WHEN WOOD IS BURNED SLOWLY, IT PRODUCES TAR AND ORGANIC VAPORS WHICH COMBINE WITH
EXPELLED MOISTURE TO FORM CREOSOTE. THE CREOSOTE VAPORS CONDENSE IN THE RELATIVELY
COOL CHIMNEY FLUE OF A SLOW BURNING FIRE. AS A RESULT CREOSOTE RESIDUE ACCUMULATES ON
THE FLUE LINING. WHEN IGNITED THIS CREOSOTE MAKES AN EXTREMELY HOT FIRE.
THE CHIMNEY SHOULD BE INSPECTED AT LEAST TWICE A MONTH DURING THE COOKING SEASON TO
DETERMINE IF CREOSOTE BUILDUP HAS OCCURRED.
IF CREOSOTE HAS ACCUMULATED IT SHOULD BE REMOVED TO REDUCE THE RISK OF A CHIMNEY FIRE.
VENTING
There are two approved methods of venting your Mugnaini wood-fired oven.
1. Direct vent with a factory built chimney.
2. Direct vent with a masonry chimney using clay flue liner.
FACTORY BUILT CHIMNEY
• Per NFPA 211 wood-burning ovens are required to use chimneys listed to UL 103 HT rated for use as a
2100° F chimney system.
• UL 103 chimneys require a minimum 2” clearance to combustible materials.
• UL 103 chimneys are available in double wall or triple wall pipe and various lengths in 6” increments.
• Only 15° or 30° elbows are available.
• An anchor plate is used as the starter piece and is to be installed per Mugnaini oven
installation instructions.
• Follow chimney manufacturer’s installation instructions for proper assembly.
MASONRY CHIMNEY
• Masonry chimneys use a 8” ID clay flue liner.
• Build chimney according to NFPA 211 standard.
NOTE: Masonry chimneys need to offer support
to keep the weight of the entire chimney off of the oven.
