Just why you did not pipe for combustion air? Or is that a concentric?

Not a confined space, also louvered vent on opposite wall, adequate combustion air. Tanks being set this week. At that point we will do more testing to determine if we pipe outside.

Good looking job. Thanks for the explanation.

As long as there is no negative pressure we will most likely leave it as is. Also the way it was explained to me, if possible the unit will run better using a steady temperature for intake air. I didn't understand but the more I think about it I guess it makes sense. Pull anywhere from -10 - 105 degree air from outside or a steady 50-60 degree air from inside year round.

Looks nice but a valve and a drain on exp tank is great for service.

Nice looking install. If your water temperature is above 140 degrees that PVC needs to be replaced with polypro or schedule 80pvc. The Propress fittings look great.

[jlanesey]

What PVC? The vent?

Yes, the vent.

Be good idea to call your Navien rep about the intake as well.

Propane? Be wise to put in low pressure cutoff. Soot that thing and nobody will be smiling.

Dark board looks awesome. Whats with the fiberglass in the window?!

[Joehvac25]

Is that gas line copper? I've never seen that before Exept soft copper with flares.

That's why I guessed propane.
