Oh yeh, it's the regulator. Gotta be the regulator. HAS to be the regulator.
Wasn't the regulator. *sigh*
$60 and hassles later, a new regulator between the dual tanks, and the &^*^*(^*^( water heater and 'fridge STILL don't work. Go read the manual. Yes. I am a geek. I do support. I ALWAYS say "Read the manual." Bad Gary.
More or less "A weak or smokey flame in the heater may mean an obstruction in the heating tube..." OK. Move the air flow gizmo out of the way and run a pipe brush into the pipe. Reset the gizmo.
Light. WWWWOOOOSSSSHHHH! Ah, um, uh... guess the pipe was obstructed.
Go over to the 'fridge. The thing won't
light. Run pipe cleaner into gas tube.
Light. Cheerful little flame. Guess THAT pipe was obstructed too.
The moral? Look for the SIMPLE stuff before spending money.
