NTI Gas combi boiler do they need to be inspected annually

jrlang63

I have new gas NTI FTVN Combi boiler installed in home. What is the recommendation for maintenance / inspection. Prior to this new boiler was i had an oil fired condensing Combi boiler and I did have it inspected annually just want to know if new gas fired boiler needs annual inspection.

Yes and maintenance information starts at page 100 in your manual so you know what to expect.

Gas is more forgiving than oil but problems will arise if it is neglected

ALL fuel burning equipment should be atleast examined annually, cleaned if needed. Mad Dog 🐕

Thank you for the feedback much appreciated.

the manufacturer will have maintenance guidelines in the manual.

Personally if I opened my boiler after the first year and it was clean, no corrosion on the flame rods, combustion numbers still in spec I’d go two or three years.

I ignored one of my mod cons for 6 or so years, it was still amazingly clean when I did open it.

Burner adjustment, and quality of combustion air has a to do with the condition of the combustion side. Keep intake and exhaust separated to avoid recycling exhaust gases.

Dust, pollen, bugs getting sucked inside can be the biggest issues.

Cleaning the heat exchanger (HX) is not an easy chore and it helps to have removable panels on the top of the outer cover, but I don't see any in their diagrams. Have a replacement igniter, flame probe, HX gasket and refractory (insulation) available in case they are damaged or need to be replaced.

For the many fire tube HX's that I've inspected, very few have built up any debris - next to none - as they are self-cleaning. So I don't clean them anymore.

Their brochure says a fire tube HX, but the technical spec's. says it's a water tube HX. NTI boilers are rare here, so I have limited experience with them.

@hot_rod It seems like nearly all of the backyard pipe-pairs Ive casually seen appear to be at some minimum separation, with the required angle deflection etc. Thanks to your highlighting this, I will put our intake down the wall further (suspended ceiling space, so can go nearly anywhere).

“Dust, pollen, bugs getting sucked inside can be the biggest issues.”

I’ve found that natural gas leftovers (aka coffee grounds) on Giannoni HX’s to be the biggest issues with low temperature systems as they will absorb acidic condensate that eats away at the HX and promotes failure.

I'm not a fan of the concentric vent caps, and I would also go more than the 12" separation if possible.

Some suggest vent through the roof, intake through the side wall. Or air from inside the space, vent through the side or roof, as the manufacturer, or code allows..

Some mod cons are fairly noisy for neighbors when vented out the side wall.
