Leon, what purpose does the L6006 do? Is it the high limit?

I have same question as Scott.
And does it have a total of 3 termination screws and 1 screw is not used?

Hello Scott, Hello McGeiver,

The L6006A is at the cold end of the boiler and plumbed
into the top of the steam chest. with the bulb in the dry well
I guess from the looks of it
===================================================================
Pulling the cover off the L6006A and looking at it:

One terminal is marked R the other W and there is a
male shovel connector at the very end.

The instructions on the inside of the cover state the following;

R-B opens, R-W closes on temp increase

I do not know what the white wheel with numbers under the
mechanism is for and I have no reason or need to mess with it.

SO its set for 120 Degrees Fahrenheit and everything works.
I have heat and abundant hot water with the anti scald mixing valve in the system.

According to Honeywell; the L6006 is used for limiting or regulating the temperature of liquids
in boilers, storage tanks and other applications where temperature control is required

As long as it works.

There, I fixed my typos :)

I believe the purpose is to shut off the stoker in the event of an outfire, so the combustion chamber doesn't fill with coal.

It certainly filled the ash basket with un burned coal
prior to the electrician finding the problem with the miss
wired thermostat wire runs.

As long as it works and I have heat that is all I care about.

I will presume that Suburban Propain will be calling me and asking why I have
not been using any kerosene. I plan on using kerosene when the
weather gets warmer anyway so...........
-----------------------------------------------------------------------------------------------------------------------------
I also found out yesterday why the probe for the Mark II Manomometer from Dwyer Instruments
has not shown up yet. They did not release it for mailing because it was not paid for in full.

I told the young woman I talked to at Dwyer Instruments that I sent a letter to her fine organization with the personal check for the exact amount requested in the E mail notification that was sent to me about my desire to purchase a probe for my Mark II manomometer.

After tracking down the sales order number she had the order released and it should be here
by the end of the week and an invoice for the small balance will be mailed to me so I can send them
a money order for the small balance.

SO I hope the shakedown cruise is over and I can get on with heating the place now.........

Hello Scott,

The hydrostat is set at 160 degrees low, 180 degrees for the high limit.

I was going to change the ash basket this morning @8:30 AM but it was only half full!!!!!!

So far, so good, the shakedown cruise continues.

What system is in place for over temp protection?

Hey Leon! You might want to re-wire the L6006 to be in line with your wire that goes to your stoker. Keeps the stoker from running if you lose a fire. As it sits, it is doing nothing.

Hello Scott,

That is where all the trouble started.

I should have called the electricians last month!!!!!!!!!!!!

At 5 threads it was too hot. I have the stoker at about 7+ threads out now and I have not
had an outfire in 36 hours or a high temp above 195 which is the internal limit on the hydrostat.

Hello Olliotj, The manual high limit setting on the Hydrostat stops the stoker from operating
and the boiler cools down unless there is a heat call.

I did not burn much coal last night with the thermostat set at 68.

Now I know the money I have spent and am spending for debt service is not :flush: :no2: :woot:

If you lose a fire, like if the power goes out for an hour and your not home, you will just start dumping raw coal into the firebox. You have a bad experience because the unit wasn't wired properly to begin with. Doesn't mean that it should be all hands off now. At least adjust it closer to the low limit temp so it can do what it is designed to do.

Hello Scott,

True, very true.

Are you saying I should bump up the L6006 from 120 degrees to 130 degrees??

The fire bed looks exactly as it should when there
is a heat call and when the stoker is idling.

I am going to see about getting some pictures taken
and doing the wiring diagram up and posting them here.

I guess since we are hardly ever gone during the week I have
not thought about it anymore.

I have been happy to have heat and I now sleep during the night.

When all this mess started; We or I were gone on the weekends taking care
of my father and is when we lost the fire and dumped the raw coal into the
ash basket.

I have to change the wiring for the stoker in the off season so that I can use a
generator if needed to run it and add the three outlets for a work light and
extension cords to keep the firebox warm in the off season.

I have to put the snowshoes on the mule and finish installing the snow caster.

Not to Rain on your Parade, but...

The true test of NOT having any out-fires is not when the heat calls are close together (as it is now colder), but when heat calls are further apart, like all the prior out-fires you had experienced.

And your electrician's recent wiring corrections have no bearing on changing what has originally caused all your prior out-fires.
You don't have to take my word for it...you will see soon enough when we have the next warming trend and the boiler has to go back into idle for some longer duration's of time. :)

Not that I have been following this closely, and, i'm just a new guy/ amateur, but I don't understand. Keystoker ships these out pretty much pre wired. And what's not already done, there is a diagram that should be followed.

Do you have a 4006b setup for a overtemp protection like they tell you to?

So which terminals are you using? R-B or R-W? This is what I was trying to figure out in previous posts when I asked which 2 out of the 3 terminals were in use, and what they were connected to.

A 6006A can be used to limit the unburned coal in the ash pan from an outfire, high limit control, or to activate a dump zone. A very versatile control, but it needs to be hooked up properly.

Keystokers typically come with a 4006B (makes on rise) aquastat. You can do the same thing with terminals R-W in your 6006A.

I almost hate to ask, but did your installers have a copy of the wiring diagram for the boiler??
