Build an Insulated Chimney Pipe Build an Insulated Chimney Pipe
Insulated chimney pipes are used in buildings that encase appliances that burn wood, oil, coal or gas. Insulated chimney pipes can withstand high temperatures, even up to 1000 degree Fahrenheit. Residential homes that use stoves must have insulated chimney pipes that will carry high heat away from the house safely.
Step 1 – Read Your Homeowner’s Manual
Leaf through your manual to discover the dimensions and the location of your chimney. If there is no information in the manual, contact the chimney manufacturer directly to get the dimensions. You must determine the flue diameter for your chimney before proper installation of chimney insulated pipe.
Step 2 – Nail in Framing Lumber
Check to see that your framing lumber is equaled to the size of your ceiling joist. Check also to see that your framing lumber opening provides enough clearance from chimney to combustibles (about 1 ½ inch clearance for 6 to 8 inch diameter and 2 inch clearance for 10 to 18 inch diameter).
Step 3 – Install Connector Pipes
Depending on whether your wood or coal burning stove is separated by a ceiling only or a floor and a ceiling, you will need to pass the insulated pipes through the length of the distance that separates the stove from the chimney outside. If your pipes must pass through a ceiling, secure a ceiling support with nails. It is to this ceiling support that you will now install the insulated chimney pipes.
Step 4 – Install the Chimney Pipe
Place over the framed opening and secure using nails. Slide a trim sleeve joint cover over the pipe that will ultimately go into the house through the support. Attach a single adapter to the pipe’s female end and then attach a flush to the other end of the adapter. Install the pipe through the opening and support. Secure the support band using metal screws, but take care not to puncture the flue. Tighten all nuts in the pipe assembly.
Step 5 – Trim the Interior
Place an interior trim plate for your ceiling slope. Secure the trim plate over the ceiling.
Step 6 – Chimney Extensions
In the case that your insulated chimney pipes should run through your fireplace up the chimney, attached the pipes to the fireplace using a bed of mortar that is allows to cure and then securing an anchor plate using bolts and metal anchors. Stack the chimney pipe over the anchor plate. Use the flange bands for each flue connection. Before this, however, wrap the flue with ceramic insulation. Place the cap over the end of the pipe. Place the V-band around flanges and tighten.
