502 - coffee, not today

#1

Post by TSPORT »

Went out on the back deck today to try out recently acquired aluminum coffee percolator I bought for camping. Figured my trusty 502 would get it done. Nah. Only had 24 ounces of water in the pot and it still wasn’t perking after 10 minutes. I guess it was close because I moved it right inside to my gas range and it was perking in a minute. There was a slight breeze which may have contributed to the poor performance or maybe the 502 just isn’t up to the task. Diameter of pot was identical to the stove. It does work great for cooking food in a pan, though. Next time I’ll try my 530 or 425.

Seems odd. A 502 should be up to the task.

My 502 seems to need extra Fount pressure to get a flame big enough to Perc coffee in a breeze too. . But I still love the little thing. The 500 is no question.

I had 25 pumps to start and about another 25 running. Burning nice and blue but definitely not large flame circle. Fount was only about 25% full. I’ll try again with more fuel and pressure in the fount. (Love my 502, too. Looks like a rat but very reliable).

You're a very patient person when it comes to coffee. I heat the water up on a 'Born to Boil' M-1950, and once hot, switch to the 502 for the perking.

"There was a slight breeze which may have contributed to the poor performance or maybe the 502 just isn’t up to the task. "

Did he tank depressurize fairly quickly? My dad's old 502 did the same thing after sitting for a good while. In the end the fuel control rod had stuck in the down position. It would run but with very low output. With the tank depressurized you might open the fuel control valve fully and lightly tap on the stove with something like a piece of wood to see if the rod will pop up.

Thanks for the tip. I’ll check it out. Tank still pressurized an hour later.

"Tank still pressurized an hour later."

Was that with the stove still operating? Do note that with the fuel control valve closed, the tank should remain pressurized. A good running 502 will usually be able to make a little of the grate get a little bit orange if there is no wind. There are probably some show and tell pictures of a good running 502 posted in the forum.

A slight breeze is all you need to defeat a 502. Get some sort of windshield, this is ALWAYS important on smaller stoves.

And pump it up. More. Lots more. The font can take it.

Isn't the burner bowl on a 502 intended to be a wind screen? I personally find the burner bowl on a 502 to do a decent job, unlike the 500 which is very susceptible without a wind screen, even in mild breezes.

I experienced the same problem. Get a wider base coffee pot and less heat is lost escaping around the base. The wider coffee pot base allows more concentration of heat under the base.

Going with a wider base pot allowed me to get a 12 cup percolator perking in about 10 to 12 minutes using a Coleman 502 stove.

No. The tank was still pressurized an hour after I shut it off. I merely wanted to point out that there is no leak. I did not add any air after initial pumping after first lit. I will try again with a fuller (fuel) fount and no wind.

Well, that is expected from a normally operating unit. If the tank depressurizes significantly after maybe 15 min while operating, then you may have a stuck fuel control rod previously mentioned.

You need to pump that thing up. When first lighting, you lose a lot of air.

I had that problem with my 502. Coffee'd be an all day project. Especially when it is chilly. So I got a 500. Much better.

I gave it another 25 - 30 pumps after it was lit. I’m guessing maybe the low fuel level combined with breeze were the issue.

I don't drink coffee but I use a 9 cup percolator To heat water with and I've never had a problem heating it up. on average about 10 minutes at 8000 plus feet of altitude little bit faster at the lower altitudes 3000 to 5000 feet. Does take longer if there's a bit of a breeze or windy out And yes I give it about an extra 20 to 25 pumps after lighting it.

Wide bottom pots heat quickly. While this picture shows my 9 cup perculator on the 508 many times my 502 has done the same job and finished the entire pot in just 15 minutes. 8 to bring to boil, 7 to perc.

Well, decided to try the same percolator on my Exponent Dual Fuel. First time I lit the stove since acquiring earlier this year. Using the fuel it had in it when I bought it. Had the coffee water boiling (24 ounces) in about 3 minutes and throttled down for a nice slow perk. If I set my 502 next to the Exponent in a perk-off, the 502 would be blushing with embarrassment! Haven't got back to the 502 since the first try to see if more fuel in fount or pressure would help. Just having fun playing. Gives me a reason to use the stoves.

Never saw a 440. I’ve seen it mentioned in print but not the stove itself. 442 maybe? I’ve got 400a’s and b’s and a few other similar stoves with different numbers and colors. Seems like Coleman liked to “freshen” things up now and then with a new name and color but basically the same stove with different generator for dual fuel and separate flame adjustment lever like on the 400a.
