Customer Q&A with Product Specialists

Lynn from Michigan asked:
Can it be run through the crawl space to the boiler connecting pipe?
Can it be run through the crawl space to the boiler connecting pipe?
None of our liners are meant to be ran through a crawl space. They are only designed to reline non-combustible chimney flues. They were not tested for clearances to combustibles outside of a masonry enclosure.
