Frequently Asked QUESTIONS

FAQ

Can I add different makes of chimney to my existing chimney system?

No, chimney components from different manufacturers cannot be combined. Code dictates that a chimney system must be comprised of components as certified by one manufacturer. Futhermore, most components are designed in such a way as not to fit correctly if matched with another system's components,  rendering it not only uncertified but extremely unsafe.

Why can’t I use stove pipe to add some length to my existing chimney?

Chimney systems by code need to be installed once a transition through a combustible (roof or wall) is required. Once the transition to chimney is made the chimney system must be completed through to termination (chimney cap). As well, an insulated chimney serves two purposes; one is to insulate the flue gases from combustibles and second is to keep the flue gases as warm as possible. If an un-insulated pipe is fixed atop a proper chimney the warm gas are prematurely cooled and can result in poor draft and excessive creosote.
