Install Chimney Cap with Spark Arrestor
Chimney cap with spark arrestor – A chimney cap may be just the ticket if you want to keep water from entering your chimney, which can cause damage to your flue pipe and combustion chamber. A chimney cap also prevents birds and other animals from entering the flue pipe. The chimney caps also prevent downdrafts and can be used in the flue tube that is used to expel fumes from burning wood, coal, gas or oil. Some chimney caps may also have a spark arrester installed to keep embers from wood fires from landing on your roof or surrounding vegetation. The chimney cap must be securely attached to the chimney to keep the wind from blowing it.
Push the chimney cap on the chimney flue pipe until it is full. Install a chimney cap with spark arrestor strap around the bottom of the cap leg. Insert a bolt through the mounting holes on each side of the belt where they meet at the bottom of the cap. Thread a nut on the end of the bolt. Tighten the bolt clockwise with a wrench. Tight no belt as the bottom of the cap and chimney flue pipe could be crushed.
Your chimney cap with spark arrestor strap should come with all mounting hardware; If not, buy stainless steel nuts and bolts from any hardware store. Always use stainless steel or other rust-free nails in outdoor environments that use of regular steel fasteners can cause rust stripes on the chimney or roof over time.
