FUEL - VARIATIONS

It is unlikely that the fuel you are using is the same viscosity as the fuel used to calibrate the oil-metering valve.

Fuel viscosity differs on a routine basis even though you purchase the same grade of oil from the same supplier.

Factors influencing oil viscosity :

The oil metering valve is calibrated for #2 diesel (unless you requested otherwise.) Burning diesel #1 (stove oil)

will allow 25% more fuel and burning kerosene will allow 50% more fuel to flow through the oil-metering valve.

IT IS IMPORTANT TO BURN THE FUEL FOR WHICH THE VALVE WAS CALIBRATED

By studying the burning characteristics (see Operation) it can be determined whether the fire is too high or too

low.

FUEL - FLOW MEASUREMENT

If your heater is burning too hot or not hot enough you can measure the oil flow and adjust the flow to obtain

the fuel consumption rates shown above. The procedure for this is as follows:-

Unscrew the flare nut and remove the fuel line. The brass coupling should be held with a wrench when

unscrewing the nut to prevent the copper line from twisting

Turn the valve knob to the 1 setting.

Measure the oil quantity of oil dripping slowly from the outlet. The following measurements should be

obtained

Knob Setting 1

Knob Setting 5

If these flow rates are not correct the grade or viscosity of the oil will be the most likely cause. (See Oil Flow
