What Size Stove Jack Do You Need?
If you're installing a wood stove, chef range, or flue with a wall, ceiling, or tent, among the very first questions you'll face is what size range jack to acquire. Get it wrong and you're taking a look at a fire hazard, a great smoky mess, or a return trip to the equipment store. Get it ideal and the setup is quick, safe, and code-compliant. Below's how to figure out the proper dimension for your configuration.
Start With Your Stove Pipeline Size
The single most important measurement is the external size of your oven pipe or smokeshaft pipe. Range jacks are sized to match this pipeline, not the stove itself, so determine the pipe that will in fact travel through the jack rather than guessing based upon the cooktop's firebox dimension.
Usual property and cabin range pipes run 4, 5, or 6 inches in size, while larger wood stoves and some outdoor timber heating systems make use of 7 or 8 inch pipe. Canvas wall camping tents and warm tents normally use 4 to 6 inch stovepipe, considering that the stoves entailed are small and portable. Constantly gauge your actual pipeline with a measuring tape as opposed to trusting the cooktop's listed specs, given that makers in some cases round or utilize slightly various pipe criteria.
Suit the Jack to the Pipeline, Not the Hole
A cooktop jack isn't just a hole cutter; it's a heat-shielding collar that keeps flammable product away from the warm pipeline. The majority of jacks are developed with an inner collar sized to the pipe size and an outer flange that extends a number of additional inches on all sides. This space is willful. It produces the clearance-to-combustibles that building and fire codes call for, so an oven jack is always going to look larger than the pipeline alone.
For instance, a jack constructed for 6 inch pipeline may have a total footprint of 12 to 14 inches throughout, even though the collar opening itself is 6 inches. When purchasing, examine both numbers: the collar dimension, which must match your pipe exactly, and the general jack measurements, tent durability which need to fit the wall or roofing system room you have available.
Think about the Material You're Cutting Into
The ideal oven jack dimension can additionally rely on what surface area it's travelling through.
Canvas or Textile (Outdoors Tents)
For wall camping tents and warm camping tents, cooktop jacks are generally a fire-resistant silicone-coated fiberglass spot stitched or grommeted into the canvas. These are sized nearly specifically to the stovepipe size with simply an inch or 2 of margin, since the surrounding fabric currently provides flexibility. A 5 inch stovepipe typically pairs with a jack ranked for 5 inches, sometimes listed as "4.5 to 5 inch" to accommodate mild pipeline variation.
Wood Framing (Cabins and Residences)
For a wall surface or roofing system made from timber framing, you'll want a rigid, insulated pipeline assistance or thimble in addition to a jack that provides at the very least 2 inches of clearance from the pipe to any combustible framing participant, though lots of codes and oven manufacturers ask for more. Constantly examine your specific stove's manual and regional building regulations, because required clearances vary based on whether the pipe is single-wall or double-wall protected.
Metal Roofing
Roof-mounted cooktop jacks (often called roofing flashing or a roof covering jack) require to match both the pipeline diameter and the pitch of your roof. These are usually flexible or been available in dealt with pitch increments, so determine your roofing system incline along with the pipe size before buying.
Do Not Forget the Storm Collar and Flashing
As soon as you've matched the jack to your pipe size, you'll usually also need a storm collar, which fits comfortably around the pipeline simply over the jack to maintain water from running down into the wall or roofing system tooth cavity. Tornado collars are sized to the same pipe diameter as the jack itself, so if you're purchasing a 6 inch jack, get a 6 inch tornado collar to match.
Quick Sizing List
Prior to you order, gone through this list.
Action the outdoors size of your real oven pipe, not the range's firebox opening. Verify whether you need single-wall or double-wall (protected) clearance specs. Check the overall footprint of the jack against your available wall, roofing system, or tent panel space. Match the storm collar size to the pipeline size also. If you're roof, determine your roofing pitch for an angled jack.
All-time Low Line
Oven jack sizing boils down to one core rule: match the inner collar to your stovepipe size, after that make certain the bordering product and clearances satisfy the requirements for whatever surface you're passing through, whether that's canvas, wood framework, or a steel roofing. When in doubt, measure twice, examine your oven's handbook for precise clearance requirements, and choose a jack ranked for your details pipeline size rather than estimating.
