Racnruss, Thank you for your purchase, if you are interested here is a simple drawing of the way I like to add a second aqua stat to the supply to shut off the blower when you run out of wood in the firebox, it is actually for the 250 but simply delete the actuator for those who do not have it on their other units, this helps to keep the heat in the boiler. Start by finding the power wire coming from the existing Aqua Stat and taking off the wire nut, the power wire then goes up to terminal R on the Honeywell strap on and then comes off the W terminal back to the blower and actuator power wires, this is set to about 160 degrees F, it will break connection shutting off the blower below 160 degrees F, A simple 60 minute timer can be wired in parallel to bypass the strap on Aqua Stat for firing up the unit
