I purchased an outdoor wood boiler and want to plumb it directly into my home oil burner.. I have baseboard heat...

You are asking a vague question. Please provide more details. What type of outdoor furnace? Brand? Size? How will/should an over-firing condition be taken care of? Type of connection plumbing and insulation? Your ideas for hooking it up to your house and what you expect out of the system? How do you want changeover to be taken care of, manually? Automatically? How big is your house and how many heating zones does it have? Is this the primary or supplementary heat?

Just a few questions in no particular order to see if we can be of help.
