bleeding the pump through a clear tube. There must be
no froth visible. There are various test kits available to
enable you to look at the oil through clear tube. There
must be no froth visible. There are various test kits
available to enable you to look at the oil through clear

tubing adapted to the supply line at the pump fitting.
Air eliminators are on the market that have potential.
Also, electronic sight glasses are being used with good
success. At times, new tubing must be run to the tank

or new fittings put on. Just make sure you get the air
out before you leave.

Any air leaks in the fuel line will cause an unstable

flame and may cause delayed ignition noises. Use only

flare fittings in the fuel lines.
4. GASKET LEAKS — If 11.5 to 12.5% CO

with a

#1 smoke cannot be obtained in the breeching, look
for air leaks around the burner mounting gasket,
observation door, and canopy gasket. Such air leaks
will cause a lower CO

reading in the breeching. The

smaller the firing rate the greater effect an air leak
can have on CO

readings.

5. DIRT — A fuel filter is a good investment.

Accidental accumulation of dirt in the fuel system
can clog the nozzle or nozzle strainer and produce a
poor spray pattern from the nozzle. The smaller the

firing rate, the smaller the slots become in the nozzle
and the more prone to plugging it becomes with the
same amount of dirt.

6. WATER — Water in the fuel in large amounts will

stall the fuel pump. Water in the fuel in smaller
amounts will cause excessive wear on the pump,
but more importantly water doesn’t burn. It chills

the flame and causes smoke and unburned fuel to
pass out of the combustion chamber and clog the

flueways of the boiler.

7. COLD OIL — If the oil temperature approaching

the fuel pump is 40°F or lower poor combustion or
delayed ignition may result. Cold oil is harder to
atomize at the nozzle. Thus, the spray droplets get

larger and the flame shape gets longer. An outside
fuel tank that is above grade or has fuel lines in a
shallow bury is a good candidate for cold oil. The
best solution is to bury the tank and lines deep
enough to keep the oil above 40°F.

8. FLAME SHAPE — Looking into the combustion

chamber through the observation door, the flame
should appear straight with no sparklers rolling up

toward the crown of the chamber. If the flame drags
to the right or left, sends sparklers upward or makes
wet spots on the target wall, the nozzle should be
replaced. If the condition persists look for fuel leaks,
air leaks, water or dirt in the fuel as described above.

9. HIGH ALTITUDE INSTALLATIONS

Air settings must be increased at high altitudes. Use

instruments and set for 11.5 to 12.5% CO

10. START-UP NOISE — Late ignition is the cause of

start-up noises. If it occurs recheck for electrode

settings, flame shape, air or water in the fuel lines.

11. SHUT DOWN NOISE — If the flame runs out of air

before it runs out of fuel, an after burn with
noise may occur. That may be the result of a faulty
cut-off valve in the fuel pump, or it may be air

trapped in the nozzle line. It may take several firing
cycles for that air to be fully vented through the

nozzle. Water in the fuel or poor flame shape can also
cause shut down noises.

NOTICE

CHECK TEST PROCEDURE. A very good test for
isolating fuel side problems is to disconnect the
fuel system and with a short length of tubing,

fire out of an auxiliary five gallon pail of clean,
fresh, warm #2 oil from another source. If the
burner runs successfully when drawing out of the

auxiliary pail then the problem is isolated to the

fuel or fuel lines being used on the jobsite.

ATTENTION TO BOILER WHILE NOT IN

OPERATION

1. IMPORTANT

IF BOILER IS NOT USED DURING WINTER
TIME, IT MUST BE FULLY DRAINED TO
PREVENT FREEZE DAMAGE.

2. Spray inside surfaces with light lubricating or

crankcase oil using gun with extended stem so as to
reach all corners.

3. With steam boilers, at end of season add sufficient

water to fill boiler to top of water column and leave
it that way until fall when water should be drained
again to proper level. If, at this time, boiler water

is dirty, drain water, flush out boiler, and refill with
clean water to prescribed water level.

4. Always keep the manual fuel supply valve shut off

if the burner is shut down for an extended period of
time.

5. To recondition the heating system in the fall season

after a prolonged shut down, follow the instructions
outlined in Section IV, Paragraphs A through K.

WARNING

This boiler contains controls which may cause the
boiler to shut down and not restart without service.

If damage due to frozen pipes is a possibility, the
heating system should not be left unattended
in cold weather; or appropriate safeguards and
alarms should be installed on the heating system
to prevent damage if the boiler is inoperative.
