Installation, Operation, And Service Instructions 

 

PRECAUTIONS 

 

Waste oil may contain many foreign materials. Waste oil may also contain 
gasoline. Therefore, specific precautions on the handling and storage of waste 
oils are to be observed when using, cleaning, and maintaining this heater. 

Use a 

screen in a funnel when pouring oil into storage tank to catch foreign 
material, i.e., gasket material and sealant fibers, etc. WARNING: This 
appliance is not designated for use in hazardous atmospheres containing 
flammable vapors or combustible dust, or atmospheres containing 
chlorinated or halogenated hydrocarbons. Do not expose this unit to rain 
or moisture. If installed in high moisture atmosphere, a special cover for 
the integrated air compressor must be obtained from factory to avoid 
rusting of internal raw metals. If this occurs, see trouble-shooting guide for 
remedy.

 Uses only crank case oil, gear oil, hydraulic oils, auto trans. Fluid, or #1 

and #2 furnace oil. Do not use old, contaminated oils that have been stored in 
underground tanks or outside barrels for long periods. Excessive water and 
sludge may be present, causing quick filter plugging.  
 

NOTES: 

The instructions contained in this manual apply to the installation, 

operation, and service of Omni Waste oil fired heaters. The following instructions 
should be carefully followed for obtaining the best possible installation, operation, 
and service conditions. Specifications are subject to change without notice. This 
heater was designed to be a primary or auxiliary heat source, but not the only 
source of heat. And provide economical disposal of waste oil. Proper operation 
depends on the consistency of the oil. Any water or foreign material in the oil may 
cause the unit to shut down. If a continuous stream of oil cannot be guaranteed 
at the heater, the main heating system should be set above freezing which will 
prevent any building damage if the waste oil heater were to become inoperative 
during subfreezing weather, i.e. supply tank empty, filter plugged, etc.  
 

UNCRATING: 

Immediately upon uncrating units, check rating plate for certainty 

of electrical and mechanical characteristics. Also, check the unit for any damage 
that may have been incurred in shipment, if any damage is found, file a claim 
with the transporting agency. The unit has been tested and inspected at the 
factory prior to crating and was in perfect condition at that time.   If anything is 
missing, check packing slip for indications of possible backorder of those parts or 
components.  Otherwise, a claim must be filed for those missing parts.
