WL110 Stoker and Fan Adjustment
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?

Please tell what all controls you tried that didn't respond.Z10396 wrote: I don't have any control response for the stoker and fan.
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.

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.
