other installations. When using a two-pipe system,
install the bypass plug in the fuel unit. The plug is
shipped in the small plastic bag attached to the oil
burner. The location for the plug is shown on the decal
on the end of the fuel unit. Remove the large hex-head
fitting and insert the plug using an Allen wrench.
Check the instructions attached to the fuel pump for
proper fuel connections. Compression fittings are not
recommended.
See Table 3 for correct fuel line sizes. NEVER
USE TUBING SMALLER THAN 3/8" (1cm).
Water Pik Technologies provides an oil filter with
the XL-3 heater. Install this filter using the fittings
provided for convenient servicing of the oil burner and
filter (see Figure 8). Post a notice near the heater
stating filter service frequency.
Provide a code approved, high quality shutoff
valve at the oil supply tank.

5.1 Water Piping
Figure 9 illustrates typical piping for pool
equipment.
The heater must be protected from back-
siphoning of water, which can result in dry starts. If
there is any chance of back-siphoning, provide a check
valve between the pool and the filter pump inlet.
Arrangement of pool system components other
than as illustrated in these diagrams can affect the
operation of the heaters water pressure switch.
Location of the heater above or below the pool water
surface can also affect operation of the switch. In
general, the pressure switch can be adjusted to
accommodate this effect if the heater water
connections are no more than six feet below the pool
water surface and no more than 15 feet above it. See
instructions for pressure switch adjustment (Section
7.6) for more information about this.
Note that when pool equipment is located below
the pool surface a leak can result in large scale water
loss or flooding. Water Pik Technologies cannot be
responsible for such water loss or flooding or the
damage caused by either occurrence.
5.2 Check Valve Installation
For normal installations, do not install a shutoff
valve or any kind of variable restriction in the water
piping between the heater outlet and the pool/spa.
Install a check valve if there is any chance of
back-siphoning when the pump stops. Do not install any
other valve in the piping between the heater outlet and
the pool, unless it is being used as a diverter valve. For
special installations such as water connections below
the water level of the pool, or for other questions
contact the Water Pik Technologies Technical Service
department at (707) 776-8200 ext. 260.
