Yes, and we did. Infact I could actually hear the valve. (1:09 – 1:11)

Thats cool, thinks for the heads up, does the spade you put on new module, hook directly to the old spark igniter tube (just pop it in ) and slip on spade onto your module ? Where you testing for spark at module by holding back and looking for arc and then check at module for 24 volts pv ?

Very Good, very good…. FRITZ

Funny you mentioned that.

The roll out was probably more due to the 4″ chimney liner. O.O

I did in a quick search.

Retail is about $140-160 FOR THE NEW ONE

A S8610U-3009 has an older version (w/jumper plug) that’s been/being discontinued since the newer one retrofits more easily.

Before it was harder to switch from a Fenwal or a Johnson Controls to Honeywell.

Now it’s easy peasy.
