Instructions for a Chimney Pipe
A chimney pipe is the lining inside a chimney that prevents creosote from accumulating on the chimney. A homeowner will occasionally need to replace the chimney pipe as it wears out. This process is similar to that of installing air ducts.
- Measure the height of the chimney from the termination plate to the top of the chimney. Ensure the length of the assembled chimney pipe is at least equal to the height of the chimney.
- Assemble the chimney pipe if it has sections. This generally involves lining the female and of one section over the male end of another section. Fasten the screws into the holes in each in joint wound. Ensure you do not overtighten the screws. A flexible chimney pipe does not require assembly.
- Fasten the bottom collar to the bottom of the chimney pipe according to your assembly instructions. This generally requires you to attach the bottom collar with screws and tighten them with a screwdriver.
- Insert the bottom of the chimney pipe into the top of the chimney and slide it down the chimney shaft until the bottom of the pipe reaches the termination plate of your chimney.
- Fasten the bottom collar of the chimney pipe to the chimney's termination plate, as indicated by the chimney pipe's installation instructions. This generally involves tightening connector screws or some other type of hardware on your termination plate.
- Slide the top chimney cap over the top of the chimney pipe until it is flush with the chimney's crown. Fasten the chimney cap to the chimney crown, usually with concrete screws or anchor bolts. Seal the chimney cap to the chimney crown with caulking.
- Attach one end of a length of flexible pipe to the termination plate with a collar bracket if you have an open stove. Attach the other end of the flexible pipe to the stove if necessary to vent the heat from the stove out of the house.
