Honeywell Q340A 30mV thermocouples

Page 3 of 3  


Well, the furnace in question is 30 years old. Home Depot, Lowe's etc. stock these Honeywell thermocouples in abundance so I'm not the only idiot leaving well enough alone.

Then upon further examination wouldnt it just be a whole lot simpler to change your next one on Thanksgiving 3 yrs from now? Let me lite a pilot, stick it on your ass and see how long you last. Bubba :-)

Keep that pilot flame adjusted to minimum... That way there's just enough heat to keep the Millevolts moving & just enough space for the soot to coat the thing & cause premature failure. Maybe a stronger flame on the thermocouple will extend it's life.?? Maybe buying a spare & testing the operational unit will keep you out of trouble. Maybe a cross ref to a different mfgr??? Sand paper can keep them going, but the first failure/revival won't be the last...

p.s. Don hO. Do you have a big call for national & statewide codebooks in SD? Where are you finding them on line? Most state codes are routed through a book store & what's on line doesn't hold water until you purchase (& read) the entire text from the state bookstore or their selected vendor...

Where have you been.. They are and have been for years, called International Code books. My state, and Minnesota accepts them in their entirety. I do work 3 states on a regular basis and 5 intermittently. Licenses to match.. I thought you also worked a number of states. The CD of codes is on line, if you have a subscription. I also keep that CD on my laptop and main computer network. Who in the business doesn't? I am also online to the Code enforcement folks and their daily reminders of things they don't like. Saves a Helluva a lot of money on repeat calls and inspections.

Whats your point? Are you not required to attend code classes every year? I attend the one in your state without fail each year. I am also required to have copies of the codes available for each job. The only digression for this is on Federal reservations, where they spell out on the contract exactly how it is to be done.

Minnesota just adopted the IMC 2001 a couple years ago... Thank heaven they defer to ASHREA 62.1 addendum N (2001) for ventilation. Prior to that MN was UMC 1991. (We're slow to adopt the latest.) Even though most states have the IMC as a basis, many have amendments. Come to MN with a standard IMC system, say an underground parking garage, & you'll be spending a ton to upgrade. Go to WI with the same system & there will be different issues rejecting the system. ND & SD are pretty straight forward & follow the code to the letter. Iowa has it's own batch of FUBAR. As for required code training, I've never heard of any. Most offered, is for info only & usually a waste of time. I attended a seminar for inspectors a few years ago, & none of them had a clue regarding the mechanical code changes & the "new" IMC. I've done quite a few WI reservation jobs, Casinos & such. Most require no code compliance at all, but usually default to the states requirements unless, as you stated, they spell everything out. Some, though not required, even have the state code officials sign off on the plans. I guess they're trying to calm the waters.
