So our exhaust pipe from our hot water heater goes up from the unit, then turns a 90 degree angle to exit the room through a hole in the drywall of the back wall, to the next room. In the next room it turns a 90 degree angle upwards and exits through the ceiling. The hole in the wall from the room the unit is in, is larger than the exhaust pipe. The previous owner had insulation stuffed around the pipe to clog the gap, and a service man said that may be a fire hazard. I'm looking to completely full this gap without causing a hazard. Please coups someone link me to the proper solution to this problem? Thanks!
