I am installing an outdoor wood furnace, that works on a non-pressurized system of water heating with pipes under ground to the designated buildings, then connected through manifolds to radiant floor heating pipes. I would like to know the publications available to guide me through the whole installation, from furance hook-up to the radiant floor tubing. The plumbers in my region are only familiar with pressurized or steam systems, and are unwilling to install this system, and those that do the installations, all have a different opinion on the way to install this system, and are usually not licenced plumbers.

I would think, that unless you have one heck of a gravity feed, that you will have to have circulation pumps. These operate at about 12 psi. Without circulation pumps I do not know how you intend to push the water thru the tubing. A little more info is needed IMHO.
The outside boiler already comes with circulation pumps. Thanks to COREYSNOW for the info on the hydronics manual. Its what I was looking for.
The system needs to be under pressure to bleed the air. 12-15psi.
For the parts not directly related to the wood boiler itself...
If you are serious about acquiring the hydronics knowledge to do it yourself, this is THE book to have:
