AA260 New Boiler Hot Water Install

Ordered fittings, looking at the directions I am still looking through my parts drawers for asbestos as required in the manual . The plumbing directions are a bit vague. On a hot water system it does not specify a low water cutoff. Now I have it in my kit, any downside to using it in my application? Also the glass water level I assume would be plugged for hydronic. Lastly for this post I have a 135' run from barn to manifolds. Circulator pump will be in manifold room at house and expansion take and air vent at boiler. Looking for any cautions or suggestions.

Use big enough pex. Insulate it properly and don't insist on putting it 4' deep

Look for a deal on anti-freeze.

Or a generator...antifreeze does provide protection against freezing, but if the radiation is marginally sized to begin with the end result may be an extra layer of clothing. Pesky leaks and chemistry monitoring are also "cons", but manageable.

Everything else sounds good...did you run some control wires with the pex?

Make sure you have a drain to light for the ditch so it cant collect water and use #2 washed native(not crushed) stone to bury the pipe. It will keep water away and provide some added insulation with all the little air pockets between the stones.
