If no wall protection is used, the common radiant-type stove or heater must be spaced out at least 36 inches from the wall. This distance may be reduced considerably if asbestos millboard and/or 28 gage sheet metal is used for wall protection.
Without a backguard, a stove or range should typically be installed at least 6 inches away from a combustible back wall surface, like drywall. With a backguard, the range can usually be installed with zero wall clearance.
The following are general minimum clearances for ranges: 1 ½ inches to nearest adjacent sidewall above the cooktop on both sides. 30 inches between the cooktop and a cabinet. 0 inches for sides below the cooktop.
If you're wondering whether you can use drywall in a fireplace insert surround, the answer is: No.
Firstly, the minimum space allowed between the cooktop elements or gas burners and combustible materials directly overhead is 600 mm. Secondly, there must be at least 50 mm clearance from the back edge of the cooktop to a non-combustible wall surface or splashback.
Air gaps are sometimes specified in stove instruction manuals but often are not. Sometimes they are “recommended”. Usually recommendations for distances to non-combustibles are between 5cm and 15cm.
There are three sets of guidelines regarding cooking appliances, let's start with those surrounding a cooktop. Guidelines recommend a minimum of 12” landing area on one side of a cooking surface, and 15” on the other side.
If no wall protection is used, the common radiant-type stove or heater must be spaced out at least 36 inches from the wall. This distance may be reduced considerably if asbestos millboard and/or 28 gage sheet metal is used for wall protection.
In general, drywall can tolerate temperatures up to 125°F (52°C) without sustaining damage.
The industry's solution for heat shields
PermaBASE cement boards are the industry-preferred choice. Installation-ready and easy-to-use, PermaBASE® cement boards eliminate the need for field fabrication, saving time while allowing for enhanced performance and wood-burning stove placement closer to the wall.
The National Fire Protection Asso- ciation (NFPA) has developed standards for clearances from walls and ceilings that are the basis for many local building codes (Table 1). All combustible materials, wood- work, unprotected walls, furniture, firewood, etc., should be no closer than 36 inches to a wood stove.
A minimum clearance of 36 inches from the top of the stove to the ceiling or any combustible materials above it. Hearth Requirements: The hearth should extend at least 18 inches in front of the loading door and 8 inches on each side of the stove.
Local building codes dictate the legal minimums for clearances to combustible materials like wood framing or panels. These mandated wood-burning stove air gaps are much more significant, usually 12 to 18 inches on the sides. Building codes don't regulate gaps for non-combustibles.
Wood stoves require heat shields both under and behind them to protect your home from heat damage. While many wood stoves include heat shields in their design, some do not.
Freestanding ranges are designed to be placed against walls, while slide-in ranges are not.
When the temperature rises, the sheetrock can expand, causing it to buckle or warp. Conversely, when the temperature drops, the sheetrock can contract, leading to cracks and gaps in the walls or ceiling. The humidity levels can also affect the finish of the sheetrock.
Standard drywall resists fire for up to an hour and usually costs around $15 per sheet. If you opt instead for Type X drywall, you get 200% of the fire resistance, and your cost only goes up around 30%. Type C provides 400% of the fire resistance of standard drywall and 200% of Type X.
The type of fastener you use can also influence the amount of weight the drywall can hold. If you opt for picture hangers or simple nails, then stick to objects that are less than 20 pounds. Flat mounted hooks and anchors may be able to hold up to 50 pounds, while drywall screws can hold about 20 pounds of weight.
Gas Ranges require a 6" side wall clearance above the counter height for proper distance from combustible surfaces. Select models may only require a 3" left side wall clearance based upon the burner configuration.
The material used to build your Heat Shield must comply to CSA B365 to be in compliance. The materials listed are 29 gauge sheet metal, Ceramic Tiles or similar non-combustible material, Ceramic Tiles on 29 gauge sheet metal, brick and brick with 29 gauge sheet metal backing. Clearance reduction ranges from 50 to 67%.
A minimum clearance 'work zone' of 40” (102 cm) should be provided in front of a kitchen stove, with a larger 48”-60” (122-152 cm) clearance provided between other kitchen appliances.
600mm of vertical clearance to a combustible surface, and 200mm of horizontal distance to a vertical surface. If these measurements can't be met, the surface in question must be protected with a fire resistant material in accordance with AG/601. 600mm to a rangehood.
Household cooking appliances shall have a vertical clearance above the cooking top of not less than 30 inches (760 mm) to combustible material and metal cabinets.
