God sent you there to save lives that day. These maintenance people out there have got to wake up. Went to a new contract customer not to long ago and they jumped out terminals 5 and 6 on M&M 150 head causing continuous burner operation during a low water condition. The excuse they gave me was the new micro switches on the newer 150s don’t hold up like the mercury ones. 😂 Luckily they keep the column clean. Great work Ray.

Fantastic explanation of how the weight of water works against pressure and the other way around. Our tech advisor has classes about the physics of this process religiously and some people just can’t grasp the concept .43 exerting 1psi rule. This factor is also key when troubleshooting pressure related issues in a hydronic system in tall buildings hence the reason for the HW boilers installed near the top floor. Great video Ray.

@@boilerroomdetective it does not. The little bit of condensate in the brass trap keeps the swing check pushed closed when under pressure. I’ve used Hoffman #26s in the past and they usually bite the dust after a few years especially in an application that has an automated steam valve on steam supply causing the boiler to go into vacuum frequently.

Just a comment, only from my experience of course, since building operators or owners started getting rid of vacuum pumps the amount of condensate tanks has increased. I think a lot of it was guess which left cool water in the pipes and the dreaded steam hammer when they mix. I think that the vacuum pump systems were better because it required you to check the actual piping and be honest! Good video. Thank you

As a young pipefitter, I had the pleasure of working with an old Master Fitter who excelled at replacing the Push Nipples between sectional boilers. Building the boiler back up and carefully tuning the connecting rods so as to allow for expansion was his specialty. And while it was labor intensive, and rarely done today, it was the way things were done back then. A quick little side story with the same Master. We enter a basement to work on an H.B. Smith boiler and as this cellar had no suitable drain we had to drain the boiler into a pail and carry the pail up and out the bulkhead to dump outside. My mentor looked at this boiler and told me to take the first 17 pails outside and then he would take the next 17. I never even considered that he knew exactly how much water this boiler would hold, and sure enough, the 17th pail only filled about half-way. And he was ready to begin working on the return piping.

As a young 19 year old I worked with my Dad, he was a plumber and his friend is a boiler guy and oil burner tech. Well, his friend needed someone to help him on a job and he asked my dad if he could borrow me for the day to help him on a job and of course he obliged. On this job was exactly the same, we put the boiler sections together in the basement and then piped and wired everything etc. Back in those days the boilers didn't come as packaged boilers, we had to put the whole thing together. Well, I liked doing the boiler / oil / gas burner work much more and my dads friend a few days later wanted to borrow me again and he did and I was eager to go on another boiler job. This happened half a dozen times or so and I told my dad that I was going to go work for his friend. My dad had no problem with it because he had my brother working for him too. I ended up working for his friend for the next 15 years or so and got my masters license. Now it's all package boilers unless it's commercial jobs and we did plenty of schools and churches etc over the years back then.

Had something similar involving a natural gas line but at least easier to troubleshoot as the problem was consistent. Two 1950's vintage high pressure steam boilers side by side with the original Ray burners. 2# gas, no regulators, just globe valves with the stems drilled and safety wired. 4" common gas pipe to a 3X3X4 bull head tee. The one boiler fired fine, the other would light the pilot but lock out on main flame ignition. All gas valves functioned properly. Determined that the gas company had just recently replaced the gas meter. The 3" meter's plastic dirt guard had not been removed and ended up in the bull head tee.

I got the L404F shown at the beginning of the video and the L4079B towards the back of the video. Both are on the boiler and its a low/high/off or low/high/low. Supposed to cut steam off at 12 psi, which I'm actually close pretty consistently at 12.5 psi. But want to get the boiler to to fire back up at 10 psi. However I cannot get the L404F to get programmed right. At one point I was fairly close, with a heat call at 9 psi and fuel call at 7psi, but its been all down hill after that. Any suggestions? I want to get some gauges and put on there with them but something ain't right. A few times I had to hit the reset button on the 4079b to get the call for heat to come up (showing less than 5psi on gauge when this happens and one time dropped to 0 with still no heat call).
@boilerroomdetective
@boilerroomdetective 3 ай бұрын
When Im setting these up, I set the manual reset limit control for 15 psi. If it has a low high low burner, I set the operating control for about 1-2 psi above the firing rate control. I set the firing rate control for my desired operating pressures. For example, If Im trying to operate between 10 and 12 psi, I will use the following settings. Manual reset limit control is set for 15 psi. The operating control to shut off around a pound less. 13.5-14 with a 2 psi differential. The firing rate control is set to shut off at 12 psi with a 2 psi differential. Good luck

Something like that can make for a very bad day. I had the exact same start up experience once years ago with a mis-wired gas valve, but fortunately for me, I discovered it before it could do damage. Luckily, the boiler room was quiet when I energized the power to the boiler and I heard the gas valve open. Not something you can hear with the blower motor running. From that day forward, I always kept the manual gas cock closest to the burner closed and never opened it until I had established a pilot and watched for proper operation.
