Stovepipe is not for outside use. Stovepipe is the pipe that goes from your appliance (woodstove, oil burner, etc.) to your chimney at the wall or ceiling. You want Class-A chimney to run outside either through the ceiling and roof or out and up an exterior side wall.What should I use; single wall or double wall stovepipe? Single wall stovepipe can be used in most applications except where there are combustibles 18" or less from where the stovepipe is going to be installed or if your local codes call for double-wall stovepipe. Double-wall stovepipe allows clearances down to 6" from wall combustibles and 8" from ceiling combustibles.Which way should I make the connections; male end up, or male end down? Stovepipe connections should always be installed with the male (crimped) ends down, pointing towards your stove. We know, this doesn't make sense to many of you because you think it should point the direction the smoke flows, but the male ends should point down to allow creosote drippings to drip back down into your stove and not out of the joints, down your pipe, and on to the floor or stove. Should I seal the joints with some sort of sealant? No, it is not necessary. Since the chimney has a negative pressure and draws air up through it, any small cracks at the joints would actually draw air into them and not allow smoke to escape. Smoke may come out however if your chimney is dirty or becoming blocked. A bigger concern would be a larger crack would allow too much cool air into the chimney. Too much cool air entering the stovepipe and chimney could cool the gases and chimney down increasing creosote formation. Bottom line; if it brings you peace-of-mind to seal all the joints, then do it with a high temp sealant. Peace of mind is worth a whole lot. But sealing is not necessaryI don't see any crimps on your22 Gauge Stovepipe, why is that? Our Heat-fab 22 ga. stovepipe has expanded female ends and straight male ends. This type of joint makes for a true inside diameter throughout the stovepipe and are much cleaner and tighter joints. Crimped male ends can decrease inside stovepipe diameter down as much as 1/2". The 24 ga. DuraVent DuraBlack stovepipe is made the same way, with no crimps, welded seams.Can I reduce the size of my exhaust on my woodstove? Your woodstove was built and designed to burn at top efficiency using the size exhaust that is has. Reducing the exhaust size will most certainly cause the woodstove smoke every time you open the doors to add wood. There are a few exceptions to this rule and the height of the chimney is the main one. The higher the chimney, the better the draft. So if you have a chimney that is around 30' tall or taller, you probably can downsize. Refer to the manufacturer of your stove for advise.Can I use your rigid stainless steel reline pipe for stovepipe?You most certainly can. As a matter of fact, if you use our Heat-fab Saf-T Liner Stainless pipe, you will most likely never have to replace stovepipe again as long as you live. You can paint it with our special HomeSaver Black Paint For Stainless Steel to cover up the shiny stainless if you would like.What is a Slip Connector and how does it work? A Slip Connector has a female end on one end and the rest of the pipe is like a male connector, slightly smaller than the regular inside dimension of smokepipe. It will telescope from 4" to 16" in another pipe. For instance; You have a 24" piece of regular 6" stovepipe and you slide the 18" Slip Connector into that pipe, you now have a pipe that will telescope from 28" to 40". Using a slip connector makes easy work of installing stove pipe, there is no cutting involved.Can I install a Tee directly to my stove? If your stove outlet ID is about 1/8" larger than the size pipe you are looking at (ie: 6" pipe = 6 1/8" inside diameter outlet), then yes. If it is exactly the same size or smaller, you will need a Male-to-Male coupling or a Tee Connector where both ends are crimped.Uplink Companies / Hart's Hearth Inc.
