well i cleaned my first hood last friday and i did alot of research before i got in to this field.let me know what u think. i read phil acklands book(thick book)lol.it was a very easy job i thought and went very smooth, but i had one question that i couldnt find the answer to im my previous book.the fire link inside the exhaust duct,do i need to cover it?i dont beleive i need to because there usually rated for 165 or higher but i would hate to make a stupid mistake that would cost me dearly.i imagine that the link would half to be heated for a few minutes or longer at the rated temp. to melt but you never no.a little history bout my company. we are a hvac/r service company in missouri which ive been doing for bout 15 years.in bussines for myself about a year.we also work on comm. kit. equip. and i found that theres nobody around here that does kit. hoods.all these rest. have companies come from 2 hours away to clean their hoods.so it didnt take me long to figure out this could get me in the door to alot of rest. that might lead to alot of work.in fact ive already got 3 rest. and this is my first week.plus i would like to do other powerwashing stuff to. so well see how it goes.i appreciate any help thanks. chris

Links go from 165 to 500 . Mc D uses 165 for electric fryers. MCD also has unwanted discharges becauses of the low temp links. your pw can set off the 165 links, especially if the company servicing the Ansul system does not change the links. When that happens, guess who gets to pay the recharge bill? Got a mirror handy?

thanks douglas.i will do a better job of checking each limit.i made up a simple cover on the last hood we did and it seemed to work fine.im still having an issue with my pricing.im either being lied to about what the comp. is charging or there not doing a very thourough job since they are so cheap.all i no is almost every customer ive talked to is unhappy with the "out of town guys"lol, but im not sure they are willing to pay to really have their hoods cleaned properly. it will be like everything else ive ever done. ill get tired of barely gettn by and i just wont do the work unless they are willing to pay me decent money to do a decent job.thanks for all the help.

why would any tech in his right mind install 165 degree links in a restaurant system . back in @1986 was the one and only disharge that I'm guilty of and it was caused by a 165 link that was actually in the pak of 360F that was accidently placed in the packaging when shipped . any real techs know that ambient temperature in the plenum easily runs min.165F with the appliance line at idle . imagine when they fire up to prep food . lol . my 165F link lasted as long as it took to warm up the cooking line , it was down stream from a salamander of all appliances. as for 450F in the ducts . hmmmmmmm ! , a damn good fire starting before the link even touchs its seperation temp of @ 420-430F . thats just my 2 bits , eh , Douglas. when we do our greasebustin in the hoods the links are not sprayed with chemicals , just hot water. sometimes , just cuz I have fire suppression knowledge will we disconnect and thoroughly clean the link line conduit , brkts , etc.Douglas Hicks said:Links go from 165 to 500 .

more on links please...
Globe tech states fusible link are not to be sprayed with chemicals, if so they must be replaced...any thoughts on this.
I have seen alot of links sprayed with foam/degreasers during cleaning.
"Fusible Links shall not be painted or coated. Fusible Links shall be replaced immediately if painted or sprayed with chemicals. "

NFPA 96 says not to disarm the system when cleaning, unless the cleaner is trained and certified in suprresion system service. Ansul says to have the system inspected after cleaning. Globe says not to get chemical on the links. I do not know how to clean w/o getting chemical on the links. Everybody seems to want to point fingers at the dumb azz hood cleaner. My experience is the hood cleaning is more difficult than system service.
I have had competitors that have not changed links for 10 or 15 years. I have seen techs put ML in Amerex systems w/o problems though Amerex only allows K links. I have seen everybody use ML & not A links in RG/Badger. I install new links after cleaning, so none of this is an issue to me. I have dumped links in the mild degreaser I use to soak nozzles in. No apparant problem. I shoud toss some in my foam tank also. If I do, I'll report on my findings.

Thank you for the kind words, Captain. And thank you for the reminder to save some links for the upcoming scientific test.

Forget the links
I changed over to the Amerex pnumatic actuation a couple years ago, and never looked back. So if any of you guys run into a plenum with a red tubing running the entire length, spray and clean away. Wont bother it at all.

It's pretty durable stuff, bumping it with a nozzle wont hurt it, but slicing it with a blade will. The tubing has 70 psi air.
