Just a little more follow up. While waiting for the new pump I thought I would try purging the air out of the system better with a garden hose pushing water back to the stove thru supply and return lines. After purging for about 30 minutes on the supply I turned the 007 pump on and had water flow! I still plan to install the bigger pump since this loop will supply water for 2 HX's and DHW I will use the 007 pump for my garage loop.
Thanks guys you all really know your stuff!

I have a drain in the house that I can hook a garden hose to and push water back to the stove to get out the air. I'll try that also.

Thanks for the ideas and suggestions! I did some more figuring and decided to get a bigger pump since this line will be eventually feeding 2 heat exchangers and domestic hot water. I ordered a 2400-20-WB I hope that will do the trick.

Thanks for all the ideas!
I should have maybe givin a few more details. This is a new install with a new pump, new heat exchanger etc. I had purged the lines from the stove through the heat exchanger to the system drain and then from the furnace to the floor drain. After doing some calculations I believe the pump is infact too small, I thought it would be close and since it was not ever used and just laying new in the box I thought I'd try it first. I have ordered a Taco 2400-20WB.

Hi guys,
I built my outdoor furnace and finally got it hooked up to my house and now I can't get the water to flow
.
I'll tell you how the system is set up and hopefully someone can help me out. The furnace is 75 ft from my house and another 35 ft to the air to water heat exchanger in my duct work, the exchanger came from a outdoor wood furnace supply house. I run 1" pex and used a Taco 007 pump I had laying around and installed the pump in the house. When I fill the furnace to proper water level the water will flow slowly to the pump by gravity, from there the pump needs to push the water up to the heat exchanger which is about 6' then back to the furnace it will barely pump the water through the heat exchanger and not a chance it will go back to the furnace. I'm guessing the pump is too small but I can't imagine a pump of even twice the size working but maybe it will.
Anyone have any input on how to get this thing working?
I'm thinking about trying 1 of those 1" fresh water pumps from Northern Tool.
Thanks
Mark
