Mantel Clearance
The necessary clearance for a mantel made of combustible
materials (e .g ., wood) varies according to the mantel depth and
height . Use the following table and illustration for information on
mantel clearance requirements for mantels made of combustible
material installed less than 10" (254 mm) above the top of the
fireplace . Do not anchor any mantel or shelf to the fireplace .
Only use metal studs above the fireplace as anchor points .
Clearance to Sprinkler
In a situation where a sprinkler head is installed within proximity to a heat release, the diagram below MUST be
followed . The distance between the sprinkler head & heat release opening cannot be less than 60" (1524 mm) in
length at every point from the origin of the heat release . You must also verify the sprinkler head sensor is set to
the proper heat setting so it does not activate when the room heats up from the fireplace being operated normally .
Please follow local building code to determine what temperature setting is relevant for your installation .
Ceiling
Sprinkler Head
Vaulted ceilings can create a channel that funnels hot air directly towards a sprinkler head placed at the
proper distance from heat release, as stated above . If sprinkler head sensor is not rated for high heat, it could
potentially set off the sprinkler system inadvertently . Please work with builder & inspector to verify your sprinkler
system is properly set to accommodate higher temperatures & is not set up in a heat channel .
