CAUTION
After checking controls by manual
adjustment, make sure they are always
reset to their proper settings.
When making changes to the controls
profi le, a combustion analyzer is
required.
Check daily that the equipment area
is free and clear of any combustible
materials, including fl ammable vapors
and liquids.
Water chemistry in the boiler must be
kept within required limits. Failure to
do so may cause premature pressure
vessel failure and will void the warranty.
LINKAGE RELATIONSHIPS
The location of the linkage rods and the speed at which the butterfl y gas valve
and butterfl y exhaust valve opens or closes will determine whether the unit
operates smoothly or not.
GAS BUTTERFLY VALVE SIDE
The longer the radius on the mod motor pivot arm, the quicker the gas butterfl y
valve shuts off . Conversely, the shorter the radius the slower the gas butterfl y
valve shuts off . The longer the radius on the gas valve pivot arm, the slower the
gas butterfl y valve shuts off . Conversely, the shorter the radius the quicker the
gas butterfl y valve shuts off .
EXHAUST BUTTERFLY VALVE SIDE
1. The longer the radius on the mod motor pivot arm, the quicker the exhaust
butterfl y valve shuts off . Conversely, the shorter the radius the slower the
exhaust butterfl y valve shuts off .
2. The longer the radius on the exhaust valve pivot arm, the slower the
exhaust butterfl y valve shuts off . Conversely, the shorter the radius the
quicker the exhaust butterfl y valve shuts off .
3. At High Fire the linkage arms should NOT begin or fi nish travel in the
vertical position. If this occurs there is a possibility that the gears will bind
and cause damage to the mod motor.
4. The gas pressure regulator is the only means for adjusting High Fire input
to the factory test fi re values. After the boiler is operated at High Fire to the
desired settings, proceed to operate at Low Fire.
5. Before the boiler fi res at high fi re:
Access Status screen on SOLA Control and press Operation.
Press yellow box next to Firing Rate.
Change Automatic to Manual in Run, and key in 100%. Press OK. Refer to
Figure 25.
