III.) Getting Started  
V.) Oil Burner  
Burner Air Adjustment: The oil burner is preset and  
performance tested at the factory (elevation 1100 feet).  
A one-time initial correction of the burner for your  
location will pay off in economy, performance, and  
extended service life.  
IMPORTANT: Proper initial installation of equipment  
will assure more satisfactory performance, longer  
service life, and lower maintenance cost.  
Make sure the water heater is on a level surface and in a  
protected area where it is not readily influenced by  
outside forces such as freezing temperatures, strong  
winds, rain, etc. Locate the water heater for easy access  
to fill fluids and make adjustments. It is recommended  
that a partition is made between the wash area and the  
water heater to prevent direct nozzle spray from coming  
in contact with the water heater. Excessive moisture will  
reduce the water heater’s service life.

1.) Turn the pump and heat switches on (Refer to  
Operation” for details). Have someone operate the  
spray gun so the burner fires.  
2.) Loosen the locking screw and close the air band  
until black smoke appears from the burner exhaust  
vent. Note the position of the white arrow on the air  
band.  
3.) Slowly open the air band until white smoke just  
starts to appear.  
4.) Turn the air band half way back to the black smoke  
IV.) Venting  
DANGER: Do not run machine indoors or in an  
enclosed area without adequate ventilation, or in  
areas where flammable vapors, (gasoline, solvents,  
etc.) may be present. Do not vent exhaust gases into  
a wall, a ceiling, or a concealed space.

Tighten the locking  
5.) Fine tune the burner air by loosening the shutter lock  
screw and turning the shutter until the exhaust is  
cleanest. Tighten the shutter lock screw.  
CAUTION: All venting must be in accordance with  
applicable federal and state laws, and local  
ordinances. Consult local heating contractors.  
Shutter  
If the water heater is to be used in an enclosed area, a  
flue must be installed to vent burner exhaust to the  
outside atmosphere. Be sure the flue is the same size  
as the burner exhaust vent on the water heater lid. Poor  
draft will cause the water heater to soot and not operate  
properly. When selecting the location for installation,  
beware of poorly ventilated locations or areas where  
exhaust fans may cause an insufficient supply of  
oxygen. Proper combustion can only be obtained when  
there is a sufficient supply of oxygen available for the  
amount of fuel being burned. If it is necessary to install  
a unit in a poorly ventilated area, outside fresh air may  
have to be piped to the burner and a fan installed to  
bring sufficient air into the unit. Locate the water heater  
in such a manner that the flue will be as straight as  
possible and protrude through the roof at a proper height  
and location to provide adequate draft. This oil fired unit  
must have a draft controller installed in the flue (Part  
#18007 call 1-800-270-0810 to order). A draft controller  
will permit proper upward airflow of exhaust flue gases.  
Shutter  
Lock Screw  
CAUTION: If white smoke appears from the burner  
exhaust vent during start-up or operation,  
discontinue use and readjust air bands.  
NOTE: If a flue is installed, have a professional  
serviceman adjust your burner for a #1 or #2 smoke  
spot on the Bacharach scale.

Follow these instructions every time you use the water heater.  
I.) Pre-Operation  
1. Connect electrical cord to NEMA receptacle, 5-15R.  
2. Connect outlet of your pressure washer to inlet of the  
water heater. Your NorthStar Water Heater is equip-  
ped with quick connect fittings, as are all NorthStar  
pressure washers. Slide the collar back on the inlet  
hose and push it over the outlet nipple of the  
pressure washer. Pull on hose to assure a good  
connection.  
2a.If your pressure washer does not have quick connect  
fittings, you can order them at 1-800-270-0810.  
2b.If you do not want quick connect fittings, the quick  
connect coupler on the inlet hose can be removed.  
The inlet hose can then be threaded directly into any  
female 3/8” NPT port.  
; A.) Position the machine for easy access to all  
controls.  
; B.) Position the machine on a solid surface, with  
less than a three degree slope, and so it is  
protected from external damage.  
; C.) Position the machine so that ambient lighting is  
sufficient for the surface you are cleaning to be  
seen with ease. Use artificial light if needed.  
; D.) Check hoses, fittings, and fuel connections for  
signs of wear, cracks and looseness, and  
replace as required.  
; E.) Read entire manual, especially the important  
safety instructions listed on page 2.  
3. Connect your existing high pressure hose and gun to  
the water heater outlet using quick connect fittings.  
3a.If your high pressure hose does not have quick  
couplers, you can order them at 1-800-270-0810.  
3b.If you do not want quick connect fittings, the quick  
connect nipple on the water heater’s outlet can be  
removed, leaving a male 3/8” NPT fitting.  
4. Fill the burner fuel tank. The tank’s capacity is four  
gallons. We recommend kerosene because it burns  
cleanest. #1 grade home heating oil, #1 or #2 diesel  
can also be used. DO NOT USE GASOLINE OR  
CRANKCASE OIL DRAINING.  
II.) Check Your Water Supply

VII.) Coil Descaling  
VIII.) Coil Desooting  
In hard water areas, scale build-up within the  
heating coil will occur. Scale deposits will decrease  
the water temperature rise and may eventually clog  
the heating coil.  
1. Mix scale remover in a 5 gallon bucket and  
elevate the bucket so it is higher than the pump  
on your pressure washer.  
2. Attach water heater’s inlet hose to the high  
pressure outlet of your pressure washer.  
3. Attach high pressure hose to the outlet of the  
water heater, but do not hook up the spray gun.  
4. Place the other end of the high pressure hose in  
the 5 gallon bucket.  
Poor grades of fuel oil or inadequate combustion  
air will cause heavy soot build-up on the outside  
surface of the heating coil. These deposits will  
insulate the coil. This will restrict the air flow  
through the coil, further aggravating the soot build-  
up.  
Most coils will never require desooting. However,  
to desoot a coil...  
1. Wear protective clothing, goggles, and gloves.  
2. Remove the flow switch from the inlet of the  
heating coil and remove the thermostat from the  
outlet of the heating coil.  
3. Remove the lid and insulation cap from the  
heating chamber and hoist the coil out. Be  
careful, the coil is very heavy.  
5. Attach a short length of hose to the garden hose  
inlet on your pressure washer.  
6. Prime the pump by filling the short length of  
hose with water, then place the end of the hose  
in the 5 gallon bucket.  
Important: Be careful not to damage the threads  
on the coil inlet and outlet. If the threads get  
damaged, it will be hard to reconnect and seal  
the fittings on the coil inlet and outlet.
