Note
High/Low Gas Pressure Switch: Low pressure switch should not be set less than 50% of manifold
pressure. High pressure switch should not be set any more than 150% of the manifold pressure.
Warning
Do not attempt to start boiler to test wiring before filling and purging the boiler. A dry fire will
seriously damage the boiler and may result in property damage or personnel injury and is not
covered by warranty.
Caution
Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper
and dangerous operation. Verify proper operation after servicing.
Note
Intake PVC piping must be assembled using cement. This will ensure that the intake is air tight
and will not allow contaminates from the boiler room into the boiler. The cement shall be free
flowing and contain no lumps, undissolved particles or any foreign matter that adversely affects
the joint strength or chemical resistance of the cement. The cement shall not show gelation,
stratification, or separation that cannot be removed by stirring.
Warning
Cements for plastic pipe are flammable liquids and should be kept away from all sources of
ignition. Proper ventilation should be maintained to reduce the hazard and to minimize breathing
of cement vapors. Avoid contact of cement with skin and eyes.
Note
Time is critical at this stage. Do not allow primer to dry before applying cement.
Note
Assembly should be completed within 20 seconds after last application of cement. Do not use
hammer to insert pipe.
Note
A Fulton Pulse boiler should not be connected to a common venting system with other types of
gas appliances.
