there is a shield which has the ul label and the testing data , also the clearance info etc. which sortof covers the secondary intake i guess. I will know more when i pick the thing up. dealers near me are pricing the 602 at 800 bucks on sale so i figure i am ok. i neglected to say i usually inventory 6 to 8 stoves at a time. i am linked to a logging / firewood business. 800 plus firewood customers. approx 7 to 8 thousand face cords of fire wood in sales. some where along the line someone always needs a stove.
