Hi Tracy, I have both of those
ports plugged and the smaller one ¼" is the one I was discussing with Lynn
… I've seen some installations where this is plumbed back into the water
pump … my expansion tank is plumbed from top of water pump outlet to
bottom of the expansion tank … see attached.
Should I run the rear iron
¼" hose directly to bottom of expansion tank, or can this be done via the
interconnection to water pump?
If direct, I'll certainly not
use the clear plastic hose.
Thanks … Jeff

Jeff, there are two ports on the rear
iron. Not sure which one you are talking about. One is on the side
(5/8" heater port which should be blocked ) and a smaller one on the top
which should go to your coolant expansion tank through a small diameter
hose. This is the primary point where the block purges air. If you
have this one blocked off, your coolant system is not configured as well as it
could be.

Lynn, there is an unused water
connection on my rear iron. At present I have a short hose on it and it's
plugged.
What about extending the hose a
bit and replacing the plug with a snifter valve, or keeping the plug and using
this hose as an auxiliary water filing point? It could easily be elevated to
the highest point in the system and used as an air burping point on the ground.
Any scheme at all that bleeds
off the trapped air is a good idea.
