How about a fairly close photo?They designed the unit perfectly. The vent is located in just a way so that no tool can get into position to grab onto it and twist.

Hi, Reach,
Sorry, I didn't know you responded. Otherwise, I would have responded back sooner!
Here is the picture.. The red circle is the size of what needs to be replaced. You notice it's behind a copper pipe..actually several pipes.
Any ideas?
I was thinking you were just trying to remove a plug -- not a big assembly.
It looks like the pipe to the left of the red circle has unions.
There are two styles of recirculation pumps depending on the age of your unit.
Older Pump with black cap has a metal wire retention clip you pull out to release the air purge valve and it pulls straight out. Be careful as it's easy to damage the O ring when replacing it. I suggest having a replacement on hand. This is the one I have.
Pump with Red cap are newer. I'm not even sure if this model needs to be removed for cleaning.
I have 6 year old Navien tankless water heater and am getting condensation on the "outside" of the black condensation collector at the bottom of the burner assembly, any ideas of the cause? It is slowly dripping out of the bottom of the unit. Could it be from check valve failure allowing cold water back through the recirculation line? I just ordered the check valves as my installer is not returning my calls. Any ideas would be great as the tech guys blew me off and no help from my installer need some place to start.

This being a DIY forum, prices are not usually discussed as prices can vary by area and also due to installation and material considerations unique to every installation.Maybe someone here has a current cost figure for the NPE-240, installed.
Was that model recommended by the dealer, or only quoted at your request?I only have the written quote for the NPN-199u
Do Navien Heaters have Anode Rods ?
This is awkward, but...
