13. Replace the oil nozzle once each season (see the
oil burner manual).
14. Oil the burner motor every three months. Use
non- detergent #40 motor oil at both oil holes.

Troubleshooting
9.1 Home Owner Heater Troubleshooting
Problems which may come up with the pool
heater operation or performance will require a trained,
professional technician. There are a few preliminary
symptoms the pool owner should check before calling
a technician:
9.1.1 Oil Burner Does Not Fire
1.
Is the pool temperature control set high enough to
call for heat?
2.
Is the pool heater switch ON? Are all circuit
fuses and remote switches ON?
3.
Is the pool filter clean?
4.
Is there enough fuel in the tank? Is the fuel valve
turned ON?
If the answer to all of these questions is yes, try
the manual overload reset switches on the burner
motor and primary control. If burner does not fire, turn
the heater switch OFF then ON, and try the reset
switches again. If the burner still refuses to fire, call
the service technician.
9.1.2 Heater Does Not Maintain the Desired
Water Temperature
1.
Is the temperature control set high enough?
2.
Is the filter cycle setting on the time clock long
enough to permit the heater to raise the
temperature?
3.
Is the heater the right size for the pool?
If these conditions are satisfactory, the heat
exchanger could be fouled, or the heater controls may
not be functioning properly. Call a service technician.
9.1.3 Burner Operates, But There is Smoke or
Pulsating Combustion
This is usually caused by improper combustion
adjustment, fouled heat exchanger or a fuel supply
problem. Call a service technician.
9.1.4 Pool Water Overheating
Turn the heater switch OFF and call a service
technician.
9.2 Professional Troubleshooting Guide
9.2.1 Introduction
A qualified oil burner technician must service this
equipment. Frequently, this service is available through
the fuel oil supplier.
WARNING
Some of these procedures involve exposing the line
voltage circuit. There is considerable danger of
electric shock.
The XL-3 is an oil-fired pool heater designed to
burn No. 2 fuel oil or No. 2 diesel fuel. Do not use
other fuels. The burner assembly comes standard with
a two-stage pump. This allows the heater to be
installed a relatively long distance from the fuel tank.
9.2.2 Initial Checks
1 . Is the oil burner connected to a one- or two-pipe
system? All units are factory set for one-pipe
systems. To convert a unit to a two-pipe system,
a bypass plug must be installed in the fuel pump.
The plug is supplied with the oil burner. There is
a decal located on the fuel pump showing where
the bypass plug goes.
If a fuel unit is set up for a two-pipe system, but
is actually connected to a one-pipe system, the
pressure in the fuel pump builds up to over 300
psi when the burner turns on. This will cause the
motor to bind and stop running or ruin the pump
seals, or both.
2.
An oil filter must be installed on the inlet line. A
very small amount of dirt in the oil can plug the
nozzle. A properly sized oil filter is shipped with
the heater (see Figure 8).
3.
Is there oil in the storage tank?
4.
Are all of the shut-off valves on the oil lines
open?
5.
Are the fuel lines adequately sized according to
the Table 3 on page 10?
6.
Are there any leaks in the fuel line? A very small
leak can cause the fuel pump to suck air into the
system, resulting in failure to operate or a
pulsating, noisy fire.
7.
Is the unit properly grounded electrically? This is
extremely important. Use of PVC piping in the
pool filter system prevents grounding through the
piping.
