ADJUSTMENTS AS MAY BE REQUIRED
WARNING
DISCONNECT MAIN POWER SUPPLY PRIOR TO ADJUSTING ANY ELECTRICAL COMPONENTS .
Hydro/Fuel Safety Modulator (Reference Figure III, item 26, Page 6)
The Hydro/Fuel Safety Modulator has been factory adjusted at 80-100 PSI. Should You desire a higher
or lower steam pressure, proceed as follows:
9.1.1
With unit operating at factory adjusted pressure, turn Hydro/Fuel Safety Modulator hex cap clock-
wise for more pressure, counter-clockwise for less pressure. Allow approximately two (2) minutes
for unit to attain new setting before readjusting the modulator again. Once desired pressure is
obtained, the Hydro/Fuel Safety Modulator will automatically maintain the pressure,
Burner Electrode Adjustment (Reference Figure A, Page 24)
9.2
9.2.1
The automatic electric ignition is preset at the factory and should not require further adjustment.
However, if electrode insulation should crack or electrode tips wear, adjustment or replacement may
be necessary. Please refer to Figure A for proper alignment of electrodes. NOTE: Electrode tip
height and position away from burner nozzle is critical for proper ignition of fuel and should be
maintained for satisfactory operation.
9.3
Float Valve Adjustment (Reference Figure VII, item 2, Page 38)
9.3.1
The float valve should be adjusted to maintain a water level of approximately three inches below water
If water level is too high or low, loosen wing-screw on ratchet float rod
tank overflow outlet.
If the selected notch lo-
mounting arm to the next notch according to the water level required.
cates the float ball too high or low, gently bend float rod until proper setting is obtained.
Pump V-Belt Adjustment (Reference Figure IV, item 22).
9.4
9.4.1
With unit in an "off" condition, loosen the four pump or motor mounting nuts and slide either for-
ward or backward until proper belt tension is acquired. Be sure to check Motor and Pump pulleys for
proper alignment. Straighten as required
Burner, Flame Detector (Figure XVII, items 41 & 42, Page 48)
9.5.1
The burner is equipped with a flame safety device which terminates burner operation in the event of
flame failure and consists of a Cad-Cell, item 42, and Main Control Switch, item 41.
9.5.2
The Cad-Cell, item 42, is mounted on the inside of the hinged transformer cover, item 5 . Remove
the Cad-Cell from its socket assembly (grasp end of cell, push in and turn counter clockwise). If
Cad-Cell has soot accumulation, wipe clean with a soft cloth and. reinstall into socket assembly.
NOTE:
The Cad-Cell clip assembly must be positioned to allow face of Cad-Cell to point directly
through the hole in the Air Tube Assembly to sight flame (See Burner Safety Control, Page 24).
Fuel Pump Pressure Adjustment (Reference Page 23)
The Fuel Pump, item 10, is factory preset at 125-135 PSI and should require no further adjustment.
9.6.1
If, for any reason, adjustment is necessary, the slotted Adjusting Screw, item 11, is located at
the upper right of the pump when viewed from the rear of the burner assembly.
To increase pressure turn slotted Adjusting Screw, item 11, clockwise. To decrease pressure, turn
9.6.2
counter-clockwise. Maximum pressure should not exceed 145 PSI. Pump will "lock out" at 150+ PSI.
Air Mixture Adjustment (Reference Figure XVII, Page 48)
9.7.1
The air intake is located on the left side of the Blower Housing and consists of two interlocking
bands, item 11. To adjust, loosen the screw on the outer band and rotate to desired position.
Retighten screw to assure permanent adjustment.
