Clean Heating Coil - Remove burner from coil by removing the four flange mount nuts. Inspect inside of

combustion chamber and if it is heavily sooted so that air passage could be a serious problem, clean the air

passage with a heavy duty vacuum. Run machine at full pressure and check the inside coil for leaks.

Check Oil Filter - Loosen nut cap of oil filter until cup and filter element can be removed. Replace the filter

element. At this time, check for water and sediment in the filter cup. Finally, clean the cup with fuel oil.

Check Oil Pump Screen - (ONLY if pump is not working properly): Remove the back of the oil pump taking care

not to lose any of the small pieces from inside the pump. The screen is a steel mesh cylinder inside the pump.

Check for water and sludge. Clean with fuel oil and replace.

Coil Maintenance - Liming of the coils is caused by mineral deposits from the water and occurs in hard water

areas. The deliming procedure requires special caution and tools to perform. We recommend that you call your

local service person if problems arise.

CHECKING FOR SCALE OR LIMING IN THE COIL

Remove outlet orifice and check for any liming. Clean the orifice if needed.

Remove outlet gun and hose.

Install a pressure gauge between the unloader and coil inlet.

Turn on the pump without the water outlet gun or outlet orifice. If the pressure reading is above 50 psi, have

your machine descaled. Else, reassemble the machine.

DESCALING

If pressure drop in the coil is over 50 psi - descaling is recommended. Descaling requires the use of highly

corrosive chemicals. It also requires the use of goggles and special protective clothing.

This procedure requires a 20L pail of descaling chemical.

Plumb the pump suction into the pail of descaling compound with a screen on the end of the suction line.

Plumb a hose from the machine outlet back in the pail of descaling compound.

Turn the pump on and circulate the compound through the machine for about 20 minutes.

After that time the chemical being pumped out of the coil should be running thin and dirty rather than foaming

heavily.

Remove the extra plumbing and reconnect machine together and run clean cold water through the machine

for five minutes.

SETTING THE COMBUSTION EFFICIENCY OF THE BURNER

Remove the flame tube assembly from the burner.

a. Remove any heavy sooting on spinner head.

b. Change oil nozzle.

c. Change electrode insulators if cracked.

d. Check electrode points for excessive wear and replace.

Check spark gap of transformer.

Ensure that the fan moves freely.

Fire the burner and check the exhaust gas with a smoke tester. Using the suitable test instruments for smoke

and CO

or O

set the air settings to obtain a trace of smoke. Measure the CO

add sufficient air to reduce the CO

otherwise specified by the appliance manufacturer's instructions EXAMPLE: 13% CO

reduced to 12% CO

Tighten all locking screws after the final adjustments are made.

Start and stop the unit several times to ensure that there are no significant rumbles or pulsations.
