So I am burning coal but I don't have any control response for the stoker and fan. Its burning but I am not sure if it is going to keep going or if it is going to get going too much. Do I need to make adjustments inside the box?

Did you follow the detailed instructions in the manual?

I did. The fire went out so switched back to oil while I do more studying.

Any tips that the manual doesn't cover?

Please tell what all controls you tried that didn't respond.

The rheostats for the stoker and fan are not responsive. No variability and they don't turn off either.i didn't move anything inside the box.

According to the manual...The rheostats only work for the idle fire timer operation...not for normal operation. ;)

I read that. I guess I'm not clear on how to adjust or what should be adjusted. I think I understand the feed screw. Just figure out how much to screw it in to keep coal feeding but not push the fire off the grate.quote="McGiever"]According to the manual...The rheostats only work for the idle fire timer operation...not for normal operation. ;)[/quote]

Code: Select all

Boiler Concept of Operation and General Information

1. The Axeman Anderson WL110 pressure Vessel holds 12 gallons of water which makes it very 

responsive during the coal fired mode, this small amount of water requires the use of a 

dump zone high limit control. The L6006 Aquastat provided with your boiler contains both 

close on rise and open on rise contacts, the common terminal R is connected to the power in 

from the circuit breaker panel/fused switch, terminal B will be connected to the Red wire 

in the Coal/Oil switch box to provide power to the boiler. This circuit will open at the 

set point of the Aquastat removing power from the boiler. Terminal W will be connected 

directly to the circulator that will dump heat from the boiler in the event the unit is 

over the set point, typically this works very well on radiant heat zones or fan coil units 

located outside the living space such as a garage or basement.
2. The L7224 triple Aquastat provides control of normal boiler high and low limits and can 

be used to run one circulator pump. The output of the burner circuit provides full power to 

the stoker motor and combustion fan and bypasses the idle circuit designed to keep the 

boiler running. For this reason it is important to set the full burn adjustment using the 

screw adjuster on the feeder prior to setting up the idle circuit. A full explanation of 

how this control works is found in the Honeywell instruction manual found with the 

documentation envelope or on our website.
3. The relay box with two rheostats on top provides an asymmetrical cycle timer and speed 

control of the stoker motor and combustion fan to keep the boiler running between burn 

cycles. The factory setting for the timer is 4 minutes off (this is the first cycle) and 2 

minutes on, the combustion fan rheostat is set for full speed and the stoker rheostat is 

set for half speed. When the burner circuit is de-energized two relays isolate the stoker 

and combustion fan from the L7224 triple aquastat and allow direct control by the timer and 

rheostats.
4. The combustion fan mounted under the feeder motor is run at full speed all the time when 

the L7224 triple aquastat calls for heat and runs by the rheostat and timer when it is not 

calling for heat.
5. The feeder motor is run at full speed all the time when the L7224 triple aquastat calls 

for heat and runs by the rheostat and timer when it is not calling for heat. The coal feed 

is adjusted by way of a adjustment screw on the back of the feeder. This adjustment must be 

accomplished prior to setting the idle fire settings using the rheostat and timer.
6. The DWYER Air Meter 460 draft gauge supplied with the boiler is designed to monitor 

draft in the base and ensure that the fly ash accumulation in the fire tubes is not 

excessive so as to effect efficiency and proper operation.
7. The oil gun is designed to hang on a bracket during coal operation and is either 

unplugged from power or disabled by a limit switch when in the stowed position.
8. There is a glass view port which covers the hole left open when the oil gun is removed, 

this glass is held in by a plate and the three screws that mount the oil gun.

8. Allow the boiler to run with the burner circuit disabled (kill power at service switch and lift B2 wire in L7224 A-stat...then turn power back on at service switch) for at least an hour and adjust the asymmetrical timer and rheostats to obtain a 1/2” fire all the way across the (Upper/Top edge of) grate. Verify the setting by allowing the boiler to run at least ½ hour after the last adjustment. Refer to the idle circuit detail on the next page for more information.
9. Remove power from the boiler (at service switch) and re-install the burner circuit wire (B2) inside the L7224 triple aquastat and take note of the timer and rheostat settings, retain information for later use.

There is no wire hooked up to B2 in the L7224 aquastat. B1?

Great, thanks. I am going to disconnect now. So I want to adjust this to get just a half inch of fire at the top on the grate?

This is how I look right now.
