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.

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.

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.

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.

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.
