Teledyne Laars Lite 2 Pool Boiler

[GforceJames]

Just a quick one does anyone happen to know the voltage that i should expect to be generated by the pilot generator/thermopile on the above boiler.

I don't mean the thermocouple, and yes I do hold the relevant acs certificates to work on these appliances.

Many thanks

Dont know the boiler in question.

Though do know that if it has a Robert Shaw gas valve then thermopile should give between 750 and 900 milivolts.

If that helps

It uses a variation of the red/white button honeywell gas valve, I could only read around 2 millivolts.

New thermopile then I think.

The thermopile is used to generate evough power to allow the gas valve solenoid to be directly operated by the thermopile with using any mains supply.

A thermostat is used in series with an o/h stat and the whole device then operates without the need for any mains power.

Some of the water cylinders with integral gas boiler operate this way. Its quite popular on American units.

I am aware of what thermopiles are, in fact they are fitted to a lot of commercial appliances i,e. Fryers/catering in general, Storage water heaters, Laundry equipment etc.

So not a stranger to them just wasn't sure what is should expect on this particular appliance, no mi's on site.

I do mainly ComCat James, By rule of thumb 750Mv is what I look for on thermopiles,

in fact they are fitted to a lot of commercial appliances i,e. Fryers/catering in general, Storage water heaters, Laundry equipment etc.

I agree

Have somewhere in the study some info on thermopiles, red/white lead, black/white lead, Ill try and find it in morn but dont hold your breath

Many thanks again, We specialize mainly in commercial work. We have to do the whole commercial and domestic scope , at renewal time it takes 2 weeks to get through it all.

Dont you find the catering regs to be the most confusing out of everything, theres so many different dates to remember and old regs, new regs.

Does my head in

Find Com Regs easy, Dom regs easier. Also find Com customers seem to think your pushing on them more legislation, take HSE CAIS 23 for instance. Many say that does,nt apply to me, well forgive me for being the one in the know but have a copy of this and you tell me, FFS

Anyway off too flop now
