NTI Ti100 Trinity Boiler fix pressure switch replacement

NTI Ti100 Trinity Boiler fix pressure switch replacement

I am NOT a plumber or certified Tech! Working on a boiler can kill you and be destructive to your property! I am not responsible for anything that you do on your own boiler. Be safe people! This is my NTI Triinity Ti100 boiler that I installed in 2009. The other day, I had a cold shower. I HATE cold showers. So much so that I have one of the largest residential solar hot water setups in all of CT. Somehow, it was cloudy for a couple days AND the boiler had stopped igniting. It was on, but not igniting. Not good. AND it was leaking! So, the leak I kinda knew about (now it was worse) and I more or less describe in the video. The ignition issue is the main problem and reason for teardown. Boiler no heat. The boiler was trying to start, it was on, but giving error 6 ... the ignitor was glowing, but no flame inside the window, as if it didn't have gas to ignite. So, either the gas valve isn't opening, or there is no gas in the lines at all. Stove works. Therefore, gas valve isn't opening. Checked the voltage going TO the gas valve in the boiler (not in video, sorry). Gas valve has voltage. So either bad gas valve, OR one of the safeties is not letting the valve open. 3 Safety sensors. Stack sensor (UPDATE TO VIDEO: sensor is 190F overtemp sensor on stack, over 190 sensor opens the circuit so as to not melt the PVC pipe), low water presure sensor, manifold limit switch ( UPDATE to video: doesn't say in manual if this is temp or pressure). The way to check and see if the safeties are not letting the gas valve open is to jumper the safeties, and troubleshoot accordingly (described in video) This method is specifically mentioned in the book as something that you SHOULD NOT DO. Here are the reasons for determining that it as ok to TEMPORARILY do that. I have a temp and pressure gauge right outside the boiler, and a standalone low water cutoff. Though the pressure was a bit low (maybe the leak?) after adding water pressure (to 15psi) there was no change in symptoms. The objective of the low water pressure sensor is just trying to make sure I wasn't running the boiler dry. Boiler wasn't dry, so I wasn't worried about that. Stack sensor I wasn't worried about because the boiler hadn't been igniting anyway, and the manifold limit sensor (pressure or temp) I wasn't worried about either because my gauge said the temp and pressures were well within normal limits. Therefore, I determined that it was safe to temporarily electrically remove the safeties from the system. After I did so, the system fired as normal. After jumpering in and out the safeties I determined that either the pressure WAS low in the system, or the low water pressure sensor was bad. After adding some pressure to the system (sensor opens the circuit below 10psi) to above 15 psi, no change. Therefore, bad sensor (pressure switch). Thanks to Boston Heating Supply I have a new one! www.bostonheatingsupply.com NOTE: if what I have posted as helped you out enough to justify paying me back in some way, this is the best way I can think of... my amazon wish list! this products here will help support future vids! thanks in advance! http://www.amazon.com/gp/registry/wishlist/24MQI7HCK8C0B/ref=cm_sw_em_r_wsl_sKWiub1ENDS2M_wb

Understanding Differential Pressure or Delta-P

Understanding Differential Pressure or Delta-P

This video, courtesy of Ashcroft, does a great job at visualizing differential pressure, or Delta-P. Commonly, filters and strainers are positioned to capture solids and particulate. The filter will obstruct the flow through the pipe lowering the pressure on the downstream side. These effects may vary depending on the filters construction. Filter media is the material that removes impurities. The smaller the pores the larger the friction. Higher friction means greater pressure drop. Contaminants for particulates that buildup in the filter will reduce media flow. As the filter becomes clogged the downstream pressure drops. This results in an increased differential pressure, also referred to as the Delta-P. Saturated filters may also begin to shed captured particles. With the filter no longer functioning properly, the contaminants can escape into the process. This is why proper monitoring of pressure drop is crucial. So how can we measure the DP? Placing taps both before and after the filter, a differential pressure measuring instrument can be connected to detect the high side and close side pressures. the instrument will report the difference between the two sides. The saturation point will be indicated when the Delta-P value reaches a predetermined threshold. This value is derived from a calculation that factors in the flow rate, fluid viscosity, and filter characteristics. When specifying a differential pressure instrument there are two important factors to consider. The first is the DP range, which is based upon the most difference in pressure that the restriction is likely to produce. The second is the instruments ability to contain the line or static pressure level.
