Theinstallationmustincludeaclean-outteetoenablecollectionofyashandtopermitperiodiccleaningoftheexhaust
system.90-degreeelbowsaccumulateyashandsoottherebyreducingexhaustowandperformanceofthestove.
Eachelboworteereducesdraftpotentialby30%to50%.
Alljointsintheventsystemmustbefastenedbyatleast3screws,andalljointsmustbesealedwithHi-TempRTV
siliconesealanttobeairtight.Theareawheretheventpipepenetratestotheexteriorofthehomemustbesealedwith
siliconeorothermeanstomaintainthevaporbarrierbetweentheexteriorandtheinteriorofthehome.
