INOV8 Model F240 – Edited September 2008
40
Oil Temperature & Pressure Settings
The INOV8 burner has been tested to burn fuel oils up to #6, and a variety of used
petroleum based shop and vehicle oils. Testing has also been done on a variety of
vegetable based oils, such as corn, soybean, and canola oils – both used and new. All of
these oils make potential fuels but have different BTU values and flashpoints that require
adjustments to the burner pressure and preheat temperature. It’s also important to be
aware that the preheat temperature showing on the LED readout is the temperature of
the steel block in the module and not the direct temperature of the oil – which can be 30
o
to 50
o
F higher than the steel block temperature. If the oil being burned is not standard
waste crankcase oil, oil analysis will determine the flashpoint and BTU value for proper
setting of the oil temperature and pressure settings. The settings below are typical:

* Flashpoints and BTU values have been obtained from US Oil Chek analysis, data
available from NFPA, and various MSDS publications and may not accurately represent
all samples. ** When adjusting oil pressure refer to instructions found on page 26.
Adjusting the Temperature Controller
Two temperature settings control the preheat function; OUT1 maintains the temperature
within 5 degrees of the set point, and OUT2 prevents the burner from firing with oil that is
not yet at the set point temperature ( also know as interlock). There are two basic factory
set points based on the type of oil specified to be used as fuel.

When making adjustments follow this procedure:
1. Press and release the SET button. The current value of OUT1 is displayed and the
SP1 and the LED for the OUT1 lights blink. Press UP or DOWN to increase or
decrease the value. The range of OUT1 temperature is 120
o
F to 180
o
F. Press SET
to confirm the new value. This will then cause SP2 and the LED for OUT2 lights to
blink.
