[RE-wrenches] Wood boiler ignition issue

Kris:

This anecdote may not help, but maybe it will amuse:  I had the unfortunate 
circumstance to reverse a hot and a neutral after rewiring an SW Plus 
inverter system.  I destroyed a bunch of appliances, including a brand new 
gas furnace.  The HVAC contractor replaced the control board for the 
furnace but although the previous control board had operated on inverter 
power, the new one would not.  I ended up buying an entire new furnace (and 
refrigerator, and on-demand water heater and some very expensive LED light 
bulbs...).

The take-away here is some appliances are on the border of 
working/not-working when powered by an inverter.  Even an exact replacement 
control board will act differently than the unit it replaced.

Good luck.
