WARNING
DO NOT USE SELF CONTAINED, NON ELECTRIC ZONE VALVES IN THE ZONE
CONTROLLED BY THE OVERHEAT CONTROL! SUCH VALVES WOULD PRE-
VENT THE OVERHEAT CONTROL SYSTEM FROM COOLING THE BOILER
WHEN NECESSARY.
NOTE
When the Solo Plus is being fired, the possibility of boiler overheating does exist. Should this
happen, the overheat aquastat, set to 200 ºF (93 ºC), must turn on an overheat zone and the C-3
circulator to dissipate heat through the heating radiation to cool the boiler. IF MORE THAN
ONE ZONE EXISTS, THE OVERHEAT CONTROL MUST BE CONNECTED TO THE RE-
LAY OR ZONE VALVE THAT CONTROLS THE CIRCULATOR FOR THE LARGEST
ZONE.
Bleeder Valve is located in tapping #22 (front left). Air should be purged
from the boiler during the start-up phase. Verify that the valve is closed.

Open the lower ash removal door and inspect the refractory chamber
bricks for damage or cracks (hairline cracks are ok and normal). Check
to make sure the combustion tunnel brick is slid fully to the rear as it
may have shifted out of place during shipping
(A).
It is not necessary to
remove the plastic and wooden shipping wedges
(B)
in the combustion
chamber. They will burn up within a few hours of initial firing.
If not installed, install a ½‖ plug in tapping #10 (front of boiler, just left
of the ash door).
There must be no valve used in this tapping. A valve or other fitting
could accidently be damaged by a dropped piece of fuel.
