Mnile I was there, I noticed that you had installed <br />a now wood burning stove without s permit and without installation <br />Inspections. I am concerned because of several serious safety problems <br />noted as followst <br />1. Manual damper in gas vent connector prohibited (811C 7401(a)). <br />Damper closes flue and allows products of combustion to enter <br />house - asphyxiation hazard. <br />3. Vent connector installed with downward pitch prohibited <br />!SK 7407, Pitch) - does not allow gas appliance to vent <br />properly and wood burning unit can back vent into gas <br />appliance. <br />3. Vent connector passinq through wall without thimble <br />prohibited 188C 7404, Clearance). The thimble is to provide <br />proper clearances and firestops. <br />1. Gas appliance coltnected to wood burning unit flue prohibited <br />(50C 7407). <br />S. Wood burning unit does not have proper testing or certification <br />(811C 103-7) Without twisting or certification, clearances to <br />combustibles, proper installation, operstiott and maintenance <br />cannot be assured. <br />6. Clearances to combustibles (4" existing) have not e.►en slat. <br />(8K 8406) must. by 360 from unprotected combustible wall. <br />7. Chimney height is not high enough - must be 2'-00 above <br />rjAge of house (ROC/UNC 37031f)). <br />•. Permit is required for installation of furnace and woodburnine <br />unit (Orono Ordinance 4o. 20.010). <br />
