Clearances to Combustible Materials
A major cause of oven-related property fire is failure to maintain the required clearances (air spaces) between
the oven and combustible materials. When planning the location for your oven, ensure that you maintain
clearances to all combustible materials, including but not limited to nearby walls, posts, ceiling structures and
vegetation.
If the oven is being built in close proximity to a structure (eg� beneath a pergola), the clearance from
combustible materials to the flue can be reduced by using a twin or triple skin ventilated flue system. If you're
planning to do this the flue must be specified and installed by a licensed professional to ensure that the flue
system is compliant with the relevant standards and local laws for your area.
If in doubt, contact a qualified plumber or your local fire authority for more information.
