DC OIL BURNER ELECTRICAL CONSIDERATIONS
* Not all generators are equally capable. A minimum of 13.0 volts must be provided at the battery.
* Generators should be operated at the maximum rated RPM during burner operation.
* Good quality batteries are strongly suggested. Batteries with higher Cold Cranking Amp (CCA) rating and deep
draw/marine type batteries are recommended.
* Use automotive rated battery cabling. All other wiring should be OEM suggested wire type and gauge.
* Protect all wiring connection points with dielectric grease.
* Ambient temperature impacts electrical requirements. Higher temperatures will result in higher amp draws.
* Increased pump operating pressure settings will increase amp draw.
* Higher gallon rate nozzles and accompanying wider air band openings will increase amp draw.

TO THE CLEANING EQUIPMENT OWNER
Since 1970, Wayne has supplied the hot water pressure washer cleaning equipment industry with oil burners. You
are obtaining a quality burner unsurpassed in engineering design and product development. It will provide you with
many years of efficient trouble-free operation, if properly installed and serviced. Please read this manual carefully.
Wayne warrants its burners specifically to those who have purchased it for resale, including your dealer. If, in any
case, you have a problem with your burner, or its installation, you should contact your dealer or the cleaning equip-
ment manufacturer for assistance.
FUEL UNITS AND OIL LINES
The model MSR-DC oil burner is provided with a single stage 3450 RPM fuel unit with by-pass plug removed for a
single pipe installation; the by-pass plug for two pipe (inlet and return) is provided in the plastic bag attached to the
fuel unit.
The installation of fuel filters are recommended. Check supply tank for sludge accumulation and leakage. Use only
flare fittings on all piping and connections since compression fittings will eventually leak. With the system running,
the vacuum should not exceed 12” mercury for single stage units. For ease of servicing, install a shut off valve near
burner.
WIRING
The MSR-DC oil burner must be electrically wired and GROUNDED in accordance with local codes or in their
absence, with National Electric Code ANS/NFPA No. 70-latest edition.
This oil burner requires a 12-volt DC power source. Use copper wire only not lighter than #12 awg. If a fused dis-
connect is used, it should be fused for a minimum of 20 amps. Refer to the wiring diagram in this manual or clean-
ing equipment manufacturers manual making sure the burner and controls are wired correctly.
AIR SUPPLY FOR COMBUSTION
The oil burner fired hot water pressure washer shall not be installed in an area where facilities for normal air circula-
tion or infiltration are so limited as to interfere with ready attainment of all necessary for proper combustion and vent-
ing. When the heating appliance is installed in a confined space, two permanent openings shall be provided. One
near the top of the enclosure and one near the bottom. Each opening shall have a free area of not less than one
square inch per 1000 BTU per hour (140 square inch per gph) of the total input rating of all the appliances in the enclo-
sure. When the building is of unusually tight construction, has an air ventilating system, exhaust fans, process dryer
or vented fireplaces, it is recommended that combustion air be supplied through two permanent openings. The open-
ings shall communicate directly, or by means of ducts, with outdoors or such spaces (attic or crawl) that freely com-
municate with outdoors. Avoid linty environments. For additional venting information, refer to the regulations of the
National Fire Protection Standard for oil burning equipment, ANSI/NFPA N0. 31-latest edition, or the cleaning equip-
ment manufacturers recommendations.
NOZZLE AND AIR HANDLING PARTS SELECTION
IMPORTANT: Thorough combustion and performance testing was done to establish the correct nozzle type and air
handling parts on this MSR-DC oil burner. Under circumstance attempt to replace or alter the oil burner nozzle type
or air handling parts (stainless steel flamelock, air cone, electrode support style static disc, blower wheel or slotted air
circumstances attempt to fire the MSR-DC oil burner under its 1.00 gph minimum or over its 2.75 gph maximum input
rating.

To remove the gun assembly once the burner has been installed on the appliance remove the ignitor/housing cover
screw and loosen the screw in the hold-down clip and swing open the transformer. Next, disconnect the copper oil
line where it attaches with a 7/16” hex flare nut on the gun assembly oil line adapter fitting and remove the 9/16” hex
gun assembly locknut. Now, grasp the rear of the gun assembly where the oil line fitting adapter exits through the
housing and pull oil line fitting adapter to the right out of the housing slot and slot plate cover. Gently lift, do not force,
the rear of the gun assembly, rotating the oil line fitting adapter up a 45 degrees pulling the entire gun assembly out
of the air tube and housing opening.
The recommended can be installed into the nozzle body adapter using the following steps. With the gun assembly
removed from the burner, loosen the electrode clamp screw and rotate the electrodes up, out of the way of a nozzle
wrench. Now, thread the nozzle into the adapter finger tight then tighten securely with a nozzle wrench. CAUTION:
Do not over tighten. Next, reposition the electrodes as shown in figure 1. At this time reinstall the gun assembly into
the burner using the preceding steps in reverse order. Position the nozzle face forward to a 5/16” setting behind the
stainless steel air cone as shown in figure 1. Once in the required position, replace the 9/16” hex lock nut and the
7/16” hex flare nut on the gun assembly and tighten the slot cover screw (see figure 2).
CAUTION: Close the ignitor and observe for spring contact with the brass buss bars, taking care not to pinch the igni-
tion transformer lead wires between the housing and cover plate. Reinstall the ignitor/housing cover screw and tight-
en the screw in the hold down clip (see figure 2).
STARTING PROCEDURE
PREPARATION STEPS
1. Calibrate and check operation of combustion analysis equipment, CO2(carbon dioxide) or O2(oxygen) analyzer,
smoke pump tester, fuel gas thermometer and oil pressure/vacuum gages. Follow the manufacture recommen-
dation for proper calibration and check out.
2. Install oil pressure gage and vacuum gage in the outlet pressure and inlet ports of the fuel unit.
3. Set oil burner slotted air band shutter 25% open.
STARTING BURNER
1. Turn off the main power switch to the burner and appliance.
2. Be sure main fuel tank is filled and all manual valves are open between the fuel tank and the burner.
3. Turn on the main power switch to the burner and appliance.
4. Prime the fuel pump per its manufacturers recommendations, check fuel unit for 100 psi delivery pressure and
check system vacuum (see paragraphs under Fuel Units and Oil Lines).
CAUTION: Do not run fuel unit dry for more than five minutes or damage to the fuel unit could result.

5. Once the fuel unit is primed (no signs of air in oil bleeder port discharge), close the bleed port. Burner will
ignite.
6. When flame is established, make a temporary air adjustment to the slotted air band for a visually clean combus-
tion smoke observed from the appliance vent. Allow the appliance to warm up approximately five minutes or until
the water temperature reaches that recommended by the cleaning equipment manufacture.
7. Adjust the slotted air band shutter until a #1 to #2 smoke (Shell Bacharach scale) is obtained at the appliance
vent.
8. Check CO2(carbon dioxide) and/or O2(oxygen) percentages and smoke in the flue gas at the appliance vent. In
general, CO2readings should be in the 10% to 12% range and O2readings in the 7.4% to 4.7% range.
9. Once the desired combustion results are attained, securely tighten slotted air band screw and check that controls
on the appliance are adjusted per the cleaning equipment manufactures instruction sheets. Remove oil pressure
and vacuum gages from the fuel unit and reinstall pipe plug fittings.
10. Check burner lighting with hot chamber, then allow burner and appliance to sufficiently cool. Then check burner
lighting with a cold chamber.
SUGGESTION: all new installations should be reinspected after one or two weeks of normal operation.
MAINTENANCE
OILING MOTOR – The MSR_DC oil burner is provided with a ball bearing shaft motor. Ball-bearing motors do not
require oiling under normal service conditions.
FILTER – The oil filter cartridge should be replaced, or sediment cleaned, periodically so the fuel oil will not become
contaminated and plug up the fuel pump and nozzle of oil burner.
NOZZLE – The nozzle should be changed at least once each year or twice a year if the cleaning equipment is used
daily through the year and should poor combustion occur. Replace with the proper nozzle.
COMPONENTS – If for any reason any of the burner parts have to be replaced, always use parts recommended by
the manufacturer. Specify part numbers and description when ordering. (IN ALL COMMUNICATIONS STATE BURN-
ER MODEL AND SIX DIGIT SPECIFICATION NUMBER).
ELECTRODE SETTINGS – This is very important for reliable ignition of the oil; check these once a year in accor-
dance with the instructions provided in this manual. Replace electrodes if worn excessively or if porcelain insulator
is oil soaked or cracked (See Figure 1).
FAN & BLOWER HOUSING – This must be kept clean, free of dirt and lint; open transformer to check fan blades
from above. Be sure the electric power is off on burner when the transformer is opened up for this inspection. Should
the blower wheel be removed for replacement or cleaning, reinstall as shown in figure 3.
