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.

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.

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?!

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

That's why I guessed propane.

Propress G fittings with L tubing for the gas line. According to navien install manual and rep non-direct combustion air intake is ok.

I'm not sure about the low pressure gas cutoff I'm just learning gas this last year and I didn't do the hook up. I understand your point though and it makes sense.
As for the fiberglass, I'm not sure. Not my house and I wasn't hired as a basement re-decorater.

Gas man says low pressure cut off built into the regulator.

When you've got a bunch of these out there and start burning through warranty reserve, remember this conversation. It may save a few trips.
Professional Member
Now your worrying me, for the 15 minutes its gonna take to pipe fresh air if its gonna save me the headache.
As for the built in regulator I checked the manufacturer spec and it is built into the valve.
Only one we ever did without direct vent I guess not worth the risk to save 20 dollars.

It's good to pipe in fresh air, If there's a gas leak inside the unit or something all of it goes outdoors through the intake. There are many other good reasons but I have to go.

what did the home owner use to heat water before?
wouldn't a conventional forced air gas furnace and power vent water heater be cheaper?
i never understood hearing some of you guys talking about combi units and hydronic fan coils in condo units and whatnot...
your install looks very nice though
