For your safety, do not store gasoline or other
flammable liquids or vapors in the vicinity of this or
any other appliance.
" symbol. Be sure to read and
WARNING
Use only #2 fuel oil or #2 diesel fuel. Heavier
fuels will not operate satisfactorily, and their use
will void the warranty.
1.3.1 Spa/Hot Tub Safety Rules
WARNING
The following Safety Rules for Hot Tubs,
recommended by the U.S. Consumer Product Safety
Commission, should be observed when using the
spa.
WARNING
The U.S. Consumer Product Safety Commission
warns that elevated water temperature can be
hazardous. Consult heater operation and installation
instructions for water temperature guidelines before
setting temperature.
1. Spa or hot tub water temperature should never
exceed 104°F (40°C). One hundred degrees
Fahrenheit (100°F [38°C]) is considered safe for
a healthy adult. Special caution is recommended
for young children.
2. The drinking of alcoholic beverages before or
during spa or hot tub use can cause drowsiness
which could lead to unconsciousness, and
subsequently result in drowning.
3. Pregnant women take note! Soaking in water
above 102°F (38.5°C) can cause fetal damage
during the first three months of pregnancy (which
could result in the birth of a brain-damaged or
deformed child). If pregnant women are going to
use a spa or hot tub, they should make sure the
water temperature is below 100°F (38°C)
maximum.
4. The water temperature should always be
checked with an accurate thermometer before
entering a spa or hot tub. Temperature controls
may vary by as much as 4F° (2C°).
5. Persons with a medical history of heart disease,
diabetes, circulatory or blood pressure problems
should consult their physician before using a hot
tub or spa.
6. Persons taking any medication which induces
drowsiness (e.g., tranquilizers, antihistamines, or
anticoagulants) should not use spas or hot tubs.
7. Prolonged immersion in hot water can induce
hyperthermia.
Hyperthermia occurs when the internal body
temperature reaches a level several degrees above the
normal body temperature of 98.6°F (37°C). Symptoms
include dizziness, fainting, drowsiness, lethargy, and an
increase in the internal body temperature. The effects
of hyperthermia include:

1.3.2 Swimming Pool Energy Saving Tips
Water Pik Technologies offers the following
recommendations to help conserve fuel and minimize
the cost of operating your pool heater without
sacrificing comfort.
1. The American Red Cross recommends a maxi-
mum water temperature of 78°F (25°C). Use an
accurate pool thermometer. A difference of 4F°
(2°C) , between 78°F and 82°F (26°C and 28°C),
will use as much as 40% more fuel.
2. Carefully monitor the water temperature of your
pool in the summertime. You can reduce heater
usage due to warmer air temperatures.
3. Set the pump time clock to start the pump no
earlier than 6:00 AM during the pool heating
season. This is the time when nightly heat loss
balances.
4. If the pool is only going to be used on weekends,
reduce the heater temperature control setting by
8 or 10 degrees during the week. Reset it to the
78°F (25°C) level a day or so before you plan to
use the pool.
5. During the winter or when on vacation for longer
than a week, shut down the heater by following
the shutdown instructions found on the inside of
the heater.
6. Where possible, shelter the pool from prevailing
winds with well-trimmed hedges or other land-
scaping, cabanas, or fencing.
7. Always use a pool cover when practical. Besides
providing a valuable safety feature, a pool cover
will reduce heat loss, conserve chemicals, and
reduce the load on filter systems.
1.4 Warranty
The Laars XL-3 heater is sold with a limited
factory warranty. Details are specified on the back
cover of this manual and the home owner's guidelines.
Make all warranty claims to an authorized Jandy
representative or directly to the factory. Claims must
include the heater serial number and model (this
information can be found on the rating plate),
installation date, and name of the installer. Shipping
costs are not included in the warranty coverage.
The warranty does NOT cover damage caused
by improper assembly, installation, operation or field
modification. Also, damage to the heat exchanger by
corrosive water is NOT covered by the warranty. See
Section 8.1 for maintaining proper pool water
chemistry.
NOTE: Keep this manual in a safe place for future
reference when inspecting or servicing the heater.
1.5 Codes and Standards
The Laars XL-3 pool and spa heater is certified
by UL (Underwriters Laboratory) as complying with
the latest standard of UL726 "Oil-Fired Boiler
Assemblies, Oil-Fired Service Water Heaters and
Swimming Pool Heaters", CAN/CSA-B140.12

2.2. Field Assembly
The Laars XL-3 heater can be installed in a
variety of ways, some of them requiring preparation or
assembly in the field. The XL-3 is shipped with the
inner stack packaged on top of the control panel door
in the box with the heater. The inner stack must be
assembled and installed before mounting the vent cap
or vent pipe. To assemble the inner stack, remove the
tape and small envelope from the sheet metal coil.
Expand the coil until the holes on each end are aligned.
Use the two screws supplied in the small envelope to
secure the ends together. Install the inner stack, 7"
(18cm) diameter, on the collar of the flue collector
before attaching the vent cap (outdoor installation) as
shown in Figure 2. The Laars XL-3 heater is also
designed for "Indoor" installations in the United States
and "Outdoor Shelter" installations in Canada when

equipped with a barometric draft control and the
appropriately sized exhaust vent.
Check the Parts List (Section 10.2) of this
manual for the correct Jandy vent cap part number.
For specific installation information see Section 2.3.5
"Indoor and Outdoor Shelter Installations".
Water connections are provided on the right side
of the heater but can be changed to the left side by
reversal of the heat exchanger. It is best to handle
these preparations before the heater is installed in its
final location. See Section 5.4 "Reversible Water
Connections" of this manual for instructions.
2.3 Location Requirements
2.3.1 Introduction
CAUTION
When pool equipment is located below the pool
surface, a leak from any component can cause large
scale water loss or flooding. Water Pik Technologies
cannot be responsible for such water loss or flooding
or resulting damage.
The Laars XL-3 heater may be installed indoors
or outdoors as outlined in later sections. Location of
the heater below or above the pool deck affects
operation of its water pressure switch. See Section
5.1 water piping for more information about this.
Avoid placing the heater in locations where it can
cause damage by water or condensate leakage. If this
is not possible, provide a suitable drain pan to catch
and divert any leakage. The pan must not restrict the
air flow around the heater.
All criteria given in the following sections reflect
minimum clearances as stated in the national
standards. However, each installation must also be
evaluated, taking into account the prevailing local

conditions such as wind speed and direction, proximity
and height of walls that may block ventilation, and
proximity to public access areas.
2.3.2 Clearances
The heater must be placed to provide clearances
on all sides for maintenance and inspection. There
must also be minimum distances maintained from
combustible surfaces (see Table 1).
At least 24" (457mm) access must be available in
front of the heater for burner removal.
If the heater is to be installed in a garage, or
similar structure, all burners and burner ignition
devices must have a minimum 18" (457mm) clearance
above the floor.
This heater must be installed at least 5 feet
(1.52m) from the inside wall of a pool unless the
heater is separated from the pool by a solid fence, wall
or other permanent solid barrier.
NOITALLATSNIROODTUO
Note: Clearances listed in Table 1 are
manufacturer's tested values. These are
given as minimum values. Where local
and national codes apply, and values
are different than those listed in Table 1,
use the greater value to ensure safe
operation.
As an alternative to the Jandy noncombustible
base plate, in the United States, the National Fuel Gas
Code allows a heater to be placed on a combustible
surface when there is a platform under the heater
made of hollow masonry no less than 4 inches (102
millimeters [mm]) thick, covered with sheet metal at
least 24 gauge thick and extending beyond the full
width and depth of the heater by at least 6 inches (76.2
mm) in all directions. The masonry must be laid with
ends unsealed, and joints matched to provide free
circulation of air from side to side through the masonry
(see Figure 3). If the heater is installed in a carpeted
alcove, the entire floor of the alcove must be covered
by a noncombustible panel.
2.3.3 Flooring
The heater must be installed on a floor of
noncombustible construction or on fire-resistant slabs
or arches. Noncombustible flooring is defined as
flooring material and surface finish not capable of
being ignited and burning and with no combustible
materials against the underside. Acceptable materials
are those consisting entirely of a combination of steel,
iron, brick, tile, concrete, slate, glass or plaster. Do not
install the heater directly on a combustible wood or
carpet floor without placing a noncombustible platform
between the floor and the heater.
The heater can be installed on a combustible
floor if a noncombustible base assembly, available
from Jandy, is used. See the Parts List (Section 10) of
this manual for the appropriate base part number.
Heaters must never be installed directly on
carpeting.

2.3.4 Outdoor Installation
For outdoor configuration, the XL-3 heater must
be installed with a factory authorized vent cap installed
over the inner stack. See Section 2.2, "Field Assembly"
for installation of the inner stack. See Section 10,
"Parts List" for instructions on ordering a factory
authorized vent cap.
Locate the heater in an open, unroofed area.
Do not install the heater under a deck. Do not locate
the heater below or adjacent to any doors, glass
openings, louvers, grills, etc., which connect in any
way with an inhabited area of a building, even though
the access might be through another structure (e.g., a
garage or utility room). In the United States there must
be a minimum of four (4) feet (1.22 m) horizontally
and four (4) feet (1.22 m) vertically between the
heater exhaust point and any door, glass opening, or
gravity inlet to a building. In Canada, the heater must
be installed so that the exhaust point of the heater is at
least ten (10) feet (3.0 m) from any building opening
(see Figure 4).
WARNING
United States
Do not install the heater with the top of the vent
assembly within 4 feet (1.22 m) horizontally and 4
feet (1.22 m) vertically of any opening into a building.
Canada
Do not install the heater with the top of the vent
assembly within 10 feet (3.05 m) of any opening into
a building.
The top surface of the heater must be at least
three (3) feet above any forced air inlet, or intake
ducts located within ten (10) feet horizontally.
If the heater is installed under an overhang, there
must be a minimum clearance of 5 feet (1.5 m) above
the top of the heater and the structure should not
overhang the heater more than 12 inches (0.30 m). The
area under the overhang must be open on three sides.
This prevents combustion gases from being diverted
into living areas through doors, windows, or gravity
inlets.
If the heater is installed close to a structure,
protect it from rain water runoff with rain gutters on
the roof or other measures. Do not locate the heater
near irrigation sprinkler systems that could spray water
on it. Water from sprinklers may cause damage to
controls and electronic components.
Avoid locations where wind deflection off nearby
structures might cause downdraft conditions. Where
downdraft conditions exist, locate the heater at least 3
feet (0.91 m) from vertical surfaces (e.g., nearby
buildings and walls).
2.3.5 Indoor and Outdoor Shelter
Installations
An outdoor shelter (Canada only) is an
unoccupied enclosure which does not communicate
directly with occupied areas. All indoor installations
and outdoor shelter installations require the addition of
a factory approved barometric draft control. The
barometric draft control must be installed without
modification and in accordance with the instructions
provided by the manufacturer.
These codes, standards and Water Pik
Technologies require that the heater be properly
vented as outlined in this manual. Proper ventilation of
exhaust and combustion air are essential for the safe
and efficient operation of the heater (See Section 3
"Venting").
Figure 4. Outdoor Heater Installation.
2.3.5.1 Installing a Barometric Draft
Control
A barometric draft control must be installed
between the heater and the vent pipe with a minimum
13 inch clearance between the chimney connector and
any combustible material. Observe NFPA Standard
No. 31 and all national and local ordinances. See
Section 3 "Venting" for the proper location of the
barometric draft control when constructing the stack.
For more information on the correct barometric draft
control for your heater, contact your local Jandy Pool
Products dealer.
Model DP Oil-Fired Heater Page 7
SECTION 3.
Venting
3.1 Combustion Air Supply
The heater location must provide sufficient air
supply for proper combustion and ventilation of the
surrounding area as outlined in the latest edition of
ANSI standard Z223.1 or in Canada, CAN/CGAB149.1 or .2, and any local codes that may be
applicable.
In general, these requirements specify that the
room in which a heater is installed should be provided
with two permanent air supply openings; one within 12
inches (305mm) of the ceiling, the other within 12
inches (305mm) of the floor. All indoor installations
must have openings to outside air for combustion,
ventilation, and dilution of flue gases from inside the
building (see Figure 5 and Table 2). Water Pik
Technologies does not recommend indoor installations
that do not provide combustion air from outside the
building.
All outdoor shelter installations (Canada only)
must have uninterrupted openings to outside air for
combustion and ventilation. The installation must be in
accordance with the latest edition of CAN/CGA B149.
Water Pik Technologies does not recommend outdoor
shelter installations that depend on internal air for
combustion. Combustion air should be ducted to the
heater from outside the structure.
Outside Air Supply: When combustion air is
supplied directly through an outside wall, each opening
should have a minimum free area of one square inch
per 4,000 BTU/Hr (1.2kW) input of the total input
rating of all appliances in the enclosed area. If air is
provided through horizontal ducts, each opening and
duct must provide one square inch of flow area for
each 2000 BTU/Hr (0.6 kW).
The XL-3 model DP3000 has an input rating of
315,000 BTU/Hr. The vent opening requirements for
the XL-3 heater are summarized in Table 2. Note that
the areas specified are net free areas and should be
increased when the openings are covered by screens,
louvers, grills or other protective covers (see Figure 5
and Table 2 notes).
Note: In Canada, follow Canadian Standard,
CAN/CGA-B149.1, .2 or local codes.

CAN1-B149.1 or .2 which differs from this table.
Note: If using screens and/or metal louvers, compensate by adding
50% additional area to each opening
If using wood louvers each opening must be at least four times
the area indicated in the table above.

(cm2)in2(cm2)
Exhaust Fans or Vents: Any equipment which
exhausts air from the room where the heater is
installed can deplete the combustion air supply or
reverse the natural draft action of the venting system.
This could cause flue products to accumulate in the
room. Additional air must be supplied to compensate
for such exhaust.
The information in Table 2 is not applicable in
installations where exhaust fans or blowers of any type
are used. Such installations must be designed by
qualified engineers.

The heater must be completely isolated and
protected from any source of corrosive chemical
fumes such as those emitted by trichlorethylene,
perchloroethylene, chlorine, etc.
WARNING
Do not store any chemicals, cleaners, or other
corrosive material near combustion air openings or in
the room. Avoid locating dryer vents in the vicinity of
combustion air openings. Failure to prevent corrosive
materials from mixing with combustion air can result
in reduced heater life and unsafe heater operation.
3.2 Exhaust Venting
The XL-3 heater has a vent collar fitting as part
of the heater's top panel. The diameter of the vent
collar and, thus, the minimum diameter of the vent pipe
to be used is 9 inches. The only correct procedure
for vent pipe sizing is to do so in accordance with
these instructions and the applicable installation
code as stated in the following "Danger"
warning.
DANGER
Vent pipe diameter must be as required by the
National fuel Gas Code Z223.1 or the Canadian
Installation Codes for Gas Appliances CAN 1-B149.1
& 2. Undersize pipe can result in inadequate venting
and oversize pipe can result in vent condensation. In
either case the result can be release of combustion
products to the indoors. This can cause serious
injury or death by carbon monoxide poisoning or
asphyxiation.
3.2.1 Outdoor Installations
For outdoor installations, a factory authorized
vent cap with a 9 inch diameter must be installed and
secured to the vent collar fitting on the top panel of the
heater. Exhaust venting considerations will determine
the placement of the heater (See Section 2.3.4). If the
heater cannot be placed so as to meet the
requirements stated in Section 2.3.4, a vent pipe may
be added to the heater to move the exhaust vent
opening to a position that complies with the
requirements. In all cases, vent pipes must be of the
same diameter as the exhaust outlet of the heater.
Approved vent pipes may be obtained through your
Jandy distributor.
3.2.2 Indoor and Outdoor Shelter
Installations
All indoor installations and outdoor shelter
installations require the addition of a factory approved
barometric draft control. The barometric draft control
must be installed without modification.
All vent installations must be made in accordance
with all local, state or provincial codes and with:
1. Chapter 7, " Venting of Equipment" of the
national Fuel Gas Code, ANSI 223.1 latest
edition, or the applicable provisions of the local
building codes.
2. In Canada, CAN/CGA B149.1 or .2.
Avoid terminating heater vents near air
conditioning or air supply fans. The fans can pick up
exhaust flue products from the heater and return them
inside the building, creating a possible health hazard.
Do not locate the vent terminal where flue
products could strike against building materials and
cause degradation.
Vent opening should be well away from trees or
other obstructions that would prevent free air flow to
and from vent terminal. Do not terminate the vent
under decks, stairways, or carports.
Be sure to support all venting so that connections
will not separate and so that the weight of the vent
pipe does not rest on the heater vent collar. All
connections should be made with rustproof sheet metal
screws. Do not weld or fasten the vent pipe to the
heater vent collar. The heater top must be easily
removable for normal heater service and inspection.
The vent collar outlet is to be connected to an
unobstructed barometric draft control and vent pipe of
the same diameter, terminating in a chimney or directly
outside the building. The vent must terminate at least
two (2) feet (0.6 m) above the highest point of the roof
or other object that is within ten (10) feet (3.0 m) of
the vent termination. The vent pipe must have a listed
vent cap which allows a full equivalent opening for flue
products (see Figure 5).
Install all venting as specified in the latest edition
of the National Fuel Gas Code ANSI Z 223.1 or in
Canada CAN/CGA-B149.1 and B149.2
Run the vent pipe as directly as possible with
minimum turns. Never use a vent smaller than 9"
(23cm). On lateral runs, maintain a minimum pitch of
1/4" (.6cm) per linear foot. If a chimney is used, the
total equivalent straight length of flue piping between
the heater and the chimney should not exceed 75% of
the vertical height of the chimney above the flue pipe
connection. The chimney should be at least 9" (23cm)
diameter. Maintain adequate clearances between the
vent pipe and combustible materials. Check local
codes and the vent manufacturers instructions for
proper clearances. The 7" (18cm) dia. inner stack
must be in place.
Any change in the amount of draft in the
combustion chamber can affect the flame
characteristics. An approved barometric draft control
must be used on all indoor installations to maintain a
clean and consistent flame (see Figure 6). When the
system is properly adjusted, the pressure in the stack
below the draft control will be approximately minus
.03" W.C. If this draft pressure cannot be achieved,
the chimney is too short or too small. Take corrective
action.
