Just recently installed a Gentleman Janitor Steam Stoker in my house and it seems to not be burning all the coal , there is lots of unburnt coal in the ash pan. I don't beleive there is any adjustment for the worm speed what can I do to burn more of the coal.
Thanks in advance

There is a adjustment for the feed rate on the older GJ's, I'm not sure about the newer ones though. If you look closely at the pulleys on the gear box and the motor you will see allen head screws. If you loosen up tension on the belt you'll be able to loosen the allen screws on the two pulleys and spin one half of the pulley in or out depending on what your trying to accomplish. What your doing is making the v shaped notch in the pulley wider or narrower. What that does is change the ratio between the gear box and the motor. It's a crude way of doing things but it is a very simple and reliable setup. But before I try messing with the feed I always give a little extra air first. Usually you can get a good burn that way. Good luck with you GJ Boiler. I'm running one for a couple of years now and am extremly happy with it. :D

I have a GJ 6-3. I have a set of instructions from Gentleman Janitor. To increase the feed adjust motor pulley diameter larger and transmission pulley smaller. This is accomplished by loosening set screw on the outer part of the motor pulley and turning clockwise. This enlarges the diameter. Repeat on the transmission pulley, but turn counterclockwise. Each half turn will increase the feed one pound per hour. To decrease feed loosen set screw and reverse above procedure or adjust motor pulley small and transmission pully larger. Take up belt slaqck to 1/2 " only.
Before attempting final adjustment of air and feed allow fire to burn at least 3-4 hours.
Air disc should be open 3-4 turns and adjusted from there. To increase air rotate counterclockwise.

Hope this helps. Good luck

Have you tried adjusting the air?

ok adjusted the belt and got the stoker burning a heck of a lot more coal then it was. now the next question I have is what should a tripple aquastat be set for for steam heat. the problem I am having now is it is taking hours for it to heat up radiators and it seems to only ever get a pound of pressure built up any suggestions would greatly be appreciated.

What are the current settings of the triple aquastat on your boiler? What is your pressuretrol currently set at? From what I've read, 1 lb of steam should be plenty for an average home.

Something else to consider, is it possible that your reduced feed rate of coal was a band-air for reduced combustion air? Make sure the blower wheel/housing is clean and that the wheel turns in the proper direction. I don't know if it is possible with a GJ stoker, but there was a recent post by EFM to check the blower rotation if you had problems with unburned coal.

Did you open the little door on the bottom and vacumn out the fines? Be sure not to break the bolts off. Fine buildup could have you only blowing air out the top rings instead of all 11 or so. :)

I just noticed your screen name? The problem may be the coal if you got it from the breaker close to honey pot. Sometimes it's excellent other times it's not so hot (pun intended). The other thing is I'm not sure it's common practice to use a triple aquastat with steam. I'm not sure why though.

I would check efm's 520 manuel. You can go to there website or I think somebody might have a link posted on here somewhere. They give a part# for the aquastat they recomend on a steam system and recomened settings. Was your GJ used on a hot water system before? If so make sure you have a low water cut off installed if you don't allready have one. I'm not far at all from you if you ever need a hand with the old girl just send me a pm. There awesome boilers and are as trouble free as they come once you get them setup.

It dawned on me while I was in the shower before. If your using a triple aquastat It proably is shuting the stoker off on your hi limit before it makes enough steam to do any good. What should happen is with a steam system the aquastat should maintain the water temp for your domestic coil and thats it. On a call for heat the stoker will run untill either the t stat is satisfied or the hi limit of the pressuretrol is reached, the aquastat won't come into play at all. I'm not sure what the highest setting is on a triple aquastat but it might be below the point at which the water will steam. Maybe you could turn your hi limit all the way up. Your pressure trol will shut the stoker off when it is satisfied if it's wired in properly.

They have the rights to the Gentleman Janitor line of stokers and the sell parts.

You could also try Mark's Supply 570-462-0748. They sell parts for just about every coal stoker you can think of and have been doing it for a very long time.
