Is It OK for a Boiler to Operate with a Sealed Air Intake and APS Closed While Fan Speed/Gas Supply Are 0?

[bwu0518]

Basically, someone installed this NT1 TRX gas boiler in my basement recently, and ever since then, there have been so many things going on. They didn’t take the air intake cap out, the exhaust started to leak, and while I am not a boiler technician, I recently started to do my own research about how the boiler could have been running for about six weeks while the air intake cap had been hermetically sealing the system for so long.

I recently discovered on my own that when the boiler is not running, the fan speed is 0, the gas power is 0, while the APS status is 1, which, based on my research, means the air pressure switch is closed. More surprisingly, there is no error code displayed on the screen.

Is this even possible? Is it possible that they likely manipulated the wires, trying to cheat the air pressure sensor so that it is always closed? Subsequently, is it possible that they also manipulated the main control board to silence the machine from reporting errors?

Also, it is really cold outside right now, and I noticed the exhaust flue temperature is 156, which, based on my research, is a very dangerous temperature for the exhaust PVC pipe as well. Is it possible that they also bypassed something so the boiler never shuts itself down?

This company also sent me a letter saying "nothing is wrong"...... while it is temporarily working though

Right side of flue has a air opening and had to be open. Both openings are not used. Page 39 right column above bottom figure. Why didn't they run outside air?
Boiler wasn't calling for heat it was because water temps were 160° were there any failures shown?

Hey, sorry I missed your reply. I’ve been investigating this with multiple sources, and I’m about to report this to federal-level authorities. I spoke with the manufacturer and the state authorities, and I’m fairly certain that someone jumped the safety sensors inside the boiler to keep it running without reporting errors. The APS sensor must have been illegally bypassed, as the boiler is currently permanently showing APS as closed regardless of whether the boiler is idle or running.

The primary air intake port was blocked 100% on this sealed-combustion unit, yet the boiler continued running for almost six weeks. This physical impossibility strongly indicates that someone manipulated the sensors inside this brand-new boiler.

Never have seen a air pressure sensor that is either failed closed or jumped that wouldn't be in a failure once it satisfied by the thermostat then get a call for heat and not fail. The burner control is made to look at safeties both ways. When not calling and not in sequence for startup. Burner running with no air would be full of soot blocked solid and would probably fail before it got that for. Black smoke would be billowing out the flue and stink. The flame would be lazy and wouldn't think it would even support a flame. Never seen this brand but the install manual post 2 the right of the flue is a combustion air opening with a option for the left of the flue with a disk that has to be cut out with a note they ony want one opening not both.

Hey, yes, that’s exactly why I’m questioning whether someone may have done something to the control board as well. As ridiculous as it sounds, my NTI TRX120 boiler is permanently showing an APS status of 1/ON (which means closed), regardless of whether the boiler is running or idle. This has been validated by the manufacturer’s online support at least three times, yet the boiler has been running with no error codes. The APS status will never show 0/OFF (open)

I believe not only that the APS was jumped, but that someone also tampered with the board. During the installation, there was mention of “getting a board” from the manufacturer, which in retrospect sounds extremely suspicious, and I am now asking the authorities to step in.

Now, the air intake cap is indeed removed, but that piece of plastic was sealing the entire boiler for six weeks, and it still kept running.

They had heat. Post1 11°td across boiler 164° 153°. Post 2 io manual. Home owner thought the boiler was running for 6 weeks with no combustion air.
