As you can see, I am new to the thread, so I apologize in advance for multiple postings.
I've run into a "vacation mode" issue with my outdoor wood boiler and gas furnace combination and would greatly appreciate any input with the problem. I have a Taylor outdoor water stove and a gas furnace. Water is circulated from the water stove with a taco pump into an exchange coil in the furnace. The blower from the furnace is used to force air through the head exchanger coil and into duct work to heat the house. The water circulation pump is wired to turn on via a relay only when the blower fan turns on. ......After 5 years of this setup, I wanted to create a "vacation mode' that will allow me to leave the house for 2-3 days and not worry about the water lines freezing. I was told my a local Taylor water stove dealer that I could wire up the circulation pump to run continuously and not worry about the lines freezing. I installed a double pole, double throw that so I can change the pump to run either from the furnace intermittantly (when the blower turns on) or by a second circuit continuously. Heres the problem................................... If my outdoor boiler is heated up to 140-160 degrees and the water circulation pump is running continuous, my gas furnace does not want to run for more than one cycle. The water to air heat exchanger is installed on the intake size of my furnace. My guess is that there must be a sensor that is sensing the heat from the heat exchanger and not allowing the furnace to re-light. It may think there is enough heat there from the heat exchanger. I think this is a furnace issue. Any ideas? I just want to be able to turn off the boiler for a few days and not worry about it freezing up in the Winter. Thanks for looking![shock !!! !!!](/talk/styles/default/xenforo/smileys/shock.gif)
