! WARNING

Non-Fulton product information is for

reference purposes only. No Fulton

document should substitute for full

review of documentation available

from the component manufacturer.

4 CAUTION

After checking controls by manual

adjustment, make sure they are always

reset to their proper settings.

When making changes to the controls

pro le, a combustion analyzer is

required.

Check daily that the equipment area

is free and clear of any combustible

materials, including  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 butter y gas valve

and butter 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 butter y

valve shuts o . Conversely, the shorter the radius the slower the gas butter y

valve shuts o . The longer the radius on the gas valve pivot arm, the slower the

gas butter y valve shuts o . Conversely, the shorter the radius the quicker the

gas butter y valve shuts o .

} EXHAUST BUTTERFLY VALVE SIDE

1. The longer the radius on the mod motor pivot arm, the quicker the exhaust

butter y valve shuts o . Conversely, the shorter the radius the slower the

exhaust butter y valve shuts o .

2. The longer the radius on the exhaust valve pivot arm, the slower the

exhaust butter y valve shuts o . Conversely, the shorter the radius the

quicker the exhaust butter y valve shuts o .

3. At High Fire the linkage arms should NOT begin or  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  re values. After the boiler is operated at High Fire to the

desired settings, proceed to operate at Low Fire.

5. Before the boiler  res at high  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
