| Mike, when you return with the burner info (most likely it's an AFG), let us know what PRIMARY CONTROL is on the burner. It's the GRAY or (most likely since it's newer) BLACK box on top of the burner.
You DO need to leave the TT jumper on the burner primary control. The burner will NOT start in any case if you remove that jumper.
You don't need the priority ON... because you have a tankless coil... the priority would only be if you were using an indirect water heater. So install the jumper from P to ZC. __________________
