What is the clearance for a wood stove?
36-inch
All stoves require a minimum 36-inch clearance to unprotected combustibles above and on all sides of the stove. A single wall stovepipe must have a clearance to combustible walls and ceilings, measured at right angles to the pipe of at least 18 inches. No clearance is needed to noncombustible walls (i.e., concrete).
How much clearance do you need for a chimney?
You’ll want particularly to see the California Chimney Code Section 2113.19 on Chimney Clearances. Chimneys must end at least 2 feet above any section of the building within 10 feet of them, and must be 3 feet above the section of roof it is built through.

How far does a wood stove have to be from the wall in Canada?
Allow 48 inches of clearance for an uncertified radiant stove and 36 inches for stoves with sheet metal jackets. Clearances can be reduced on certified and uncertified stoves by permanently mounting a sheet-metal, brick, stone or ceramic tile shield to the wall behind the stove.
How much clearance do you need for double wall stove pipe?
The NFPA calls for an 18″ clearance to combustible walls for single wall stove pipe. Double wall stovepipe is used when you don’t have 18″ or more clearance from combustibles. Most of the double wall stove pipe allows for 6″ clearance from wall combustibles and 8″ from ceiling combustibles.
What do you put on the wall behind a wood stove?

What is the proper height for a chimney?
The most common of these being the 2 foot, 10 foot, 3-foot rule. Roughly this means that a chimney should be 3 feet higher than the point it passes through a roof, while also being at least 2 feet taller than any part of a building that’s within 10 feet of the chimney.
How do I reduce the clearance on my wood stove?
Clearance should be three times the diameter of the pipe, e.g., a 6-inch pipe needs 18 inches of clearance. Heat shields may be used to reduce the clearance by the same ratio as for the stove. For example, with sheet metal you can reduce the clearance by two-thirds, from 18 inches to 6 inches.
Do I need a heat shield for my wood stove?
Wood stove clearances cannot be eliminated entirely, but they can be reduced significantly by using a properly constructed heat shield. It’s critical that heat shields are designed properly, and that rated clearance reductions for the type of shield are followed.
What is considered a non-combustible wall?
Non-combustible materials are building materials that do not burn or ignite when subjected to expected levels of fire or heat. Examples of non-combustible materials include brick masonry, concrete blocks, hardy backer board, calcium silicate board, cement board, metal, and certain types of glass.

What are the minimum clearances for combustible walls?
Table 1 shows the minimum clearances from combustible walls and ceilings. Wood frame walls covered with dry wall are considered combustible. If no wall protection is used, the common radiant-type stove or heater must be spaced out at least 36 inches from the wall.
What can be used as clearance reducing material?
A variety of materials can be used for clearance-reducing shields, from simple sheet metal to more decorative shields using brick, stone slices or ceramic tiles. Shields must be permanently mounted to walls. Free-standing, folding panels should not be used as shields.
What’s the maximum clearance for a masonry wall?
The reduction is specified by NFPA and most codes. For example, when required clearance with no protection is 36 inches, a 3 1/2-inch-thick masonry wall with ventilated air space used as a wall protector, reduces clearance by maximum of 66 percent, to 12 inches from the combustible wall.
