After several years of working flawlessly, My original Bowen
water heater has began a new trick. The pilot light seems to work fine. BUT when I turn up the temp dial, I get a large flame shooting out at me and it starts the air adjustment venturi a blazing!! The only way to control this is to shut down the temp.
For years it would simply shoot a nice jet deep into the heater
and worked just fine. On and off as needed to mantain the temp.
I suspect that the main burner has become rusted to the point
that the flame would rather head south toward the air adjustment window insted of north into the tank.
Any suggestion beyond the obvious of "take it to a qualified tech"
and bring wads of cash?
What are some easy, safe ways to deter spiders from nesting in the hot water heater? Additional screening? Mothballs? I'm in my trailer full-time so the spider-attracting propane is running daily. I just had my 10 month old heater repaired after a web caused a back-flame which melted the t-set diode and another wire.
