Checking venting on a gas water heater
I have a Rheem Fury gas water heater that was running great until two days ago. It seems that the upper surface of the heater is hotter than usual, and there is a burning smell in the same area.
Is something wrong with a heater, vent blocked or something else?
Can you help, please, I am afraid to run the water heater and I don't have hot water for shower and dishes.
