A general clearance of 18” (0�5 m) in every direction is recommended for servicing around each Burner� This ensures adequate
air flow in and around the Heating System�
In addition to this it is very important to observe the minimum clearance to combustibles at all times to avoid any
possibility of property damage or personal injury.
Table below lists the minimum clearance to combustible materials for various installation configurations� Additional clearance
may be required for glass, painted surfaces and other materials which may be damaged by radiant or convective heat�
Combustible materials are considered to be wood, compressed paper, plant fibres, plastics, Plexiglas or other materials
capable of being ignited and burned. Such materials shall be considered combustible even though flame-proofed,
fire-retardant treated or plastered.
Adequate clearance to sprinkler heads must be maintained� NOTE: Sprinkler head heat fuse link performance may alter with
age�
The stated clearance to combustibles represents a surface temperature of 90°C (50°F) above room temperature� Building
materials with low heat tolerance (such as plastics, vinyl siding, canvas, tri-ply, etc�) may become subject to degradation at
lower temperatures� It is the installer’s responsibility to ensure that adjacent materials are protected from degradation�
