Core Knowledge Reference Manual, First Edition, published Fall 2018. The manual covers combustion, heat transfer, construction, safety principles, and installation knowledge. This includes regulations and instructions, venting, ventilation, and basic electricity.
New in 2018!  The new NFI exam format makes it easier and less expensive to obtain multiple certifications by eliminating the redundancies between the Woodburning Gas and Pellet certifications.
To get your first certification you must pass the Core Knowledge (60 questions) and the fuel type (40 questions) of your choice.  To get subsequent certifications you simply must take the additional fuel-type exam.
Please call the NFI office if you have any questions. 703-524-8030
