SAFETY COMPONENTS

FLOW SWITCH

The flow switch prevents the burner from being turned on if there is insufficient water. Proper water flow causes

the magnetic core to be pushed up, closing the reed contact. This contact is interlocked with the fuel solenoid

valve in the oil pump.

SAFETY RELIEF VALVE

The Relief Valve prevents the machine from being subjected to abnormally high pressures. If this situation occurs,

the valve will blow off relieving the pressure in the coil. This valve may also operate if the unloader is adjusted too

high.

THERMOSTAT

The built-in thermostat stops the unit from overheating. Maximum temperature of the unit is 212°F.

HIGH LIMIT SWITCH

The High Temperature Limit Switch is a thermostat which is set to 230°F. This switch is not adjustable and will

only operate when other controls fail to keep the water temperature within the normal operating range. This

switch cuts the power to the fuel solenoid
