Warning: The clearances
below are also applicable
to items that may be
stored below heaters.
These clearances apply to
both natural gas and
propane heaters.
Clearances & Safe Mounting Practices.
Each heater must be installed so that the following “minimum clearances to combustibles”
are maintained. Combustible materials are considered to be wood, compressed paper,
plant fibers, or other materials capable of being ignited and burned. Such materials shall
be considered combustible even though flame proofed, fire retardant treated or plastered.
Additional clearances may be required for glass, painted surfaces, plastics, vinyl and other
materials which may be damaged or melted by radiant or convection heat. A minimum
clearance of 24 inches (above the heater) must be maintained to plastics, vinyl or any
other materials that may be adversely affected by radiant or convection heat.
