minimum of 4 feet (1.22 m) horizontally or vertically
between the heater and any door, glass opening, or
gravity inlet to a building (see Figure 3).
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 direc-
tions. 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 4). If
the heater is installed in a carpeted alcove, the entire
floor of the alcove must be covered by a non-combus-
tible panel. You can obtain a non-combustible base
from Teledyne Laars, part number 10521701-05.
Figure 3. Outdoor Heater Installation.
WARNING
United States
Do not install the heater with the top of the
vent assembly within 4 feet (1.22 m) 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.
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.
Notes:
1. Blocks must provide solid base and be braced so they
cannot slip out of place.
2. Air openings in blocks must be arranged to provide
unrestricted opening through entire width or length of
base.
Figure 4. Non-Combustible Platform.
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 sprinkler systems that could spray water on it.
Avoid locations where wind deflection off nearby
structures might cause wind loading and 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). The
addition of a vent cap may be necessary.
2D. Combustion and Ventilation Air
Supply
All indoor installations must have openings to
outside air for combustion, ventilation, and dilution of
flue gases from inside the building (see Figure 2 and
Table 1). Teledyne Laars 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.
Teledyne Laars does not recommend outdoor shelter
installations that depend on combustion air for com-
bustion.
2C-3. Flooring - Typical Installation
Do not install the heater directly on a combus-
tible wood or carpet floor without placing a non-
combustible platform between the floor and the heater.
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

6. Install a manual gas shutoff valve for service and
safety. Do not use a restrictive gas cock. DO
NOT USE GAS FLEXIBLE PIPING.
7. Disconnect the heater and its individual shutoff
valve from the gas supply system during pressure
testing of the system at pressures higher than 1/2
pounds per square inch (psi) (3.45 kilopascals
[kPa]). If the test pressure is equal to or less than
1/2 psi (3.45 kPa), close the manual shutoff valve
on the heater during the piping pressure test.
1. Gas piping installation must be in accordance
with the latest edition of ANSI Z223.1. In
Canada, the installation must be in accordance
with CAN- B149.1 or .2 and all local codes that
apply.
2. Check the rating plate to make sure the heater is
fitted for the type of gas being used. Teledyne
Laars heaters shipped from the factory are
certified to operate at an altitude of 0 to 2000 feet
(0 to 609 m), or if so ordered, at higher altitudes.
In the United States, the heater manifold is
marked with a tag or sticker indicating one of the
following high altitude operation codes:

Notes:
1. These numbers are for natural gas (0.65 Sp. Gr.) and are
based on 1/2 inch (13 mm) water column pressure drop.
Check supply pressure with a manometer, and local code
requirements for variations. For liquefied petroleum gas,
reduce pipe diameter one size, but maintain a 3/4 inch
(13 mm) minimum diameter.
2. Check supply pressure and local code requirements
before preceding with work.
3. Pipe fittings must be considered when determining gas
pipe sizing.
3. In Canada, the heater rating plate is marked for
specific altitude requirements: high altitude (H) is
2,000 to 4,500 feet (609 to 1372 m) above sea
level.
4. Use the figures in Table 3 to size the gas inlet
piping from the gas meter to the heater. Check all
local codes for compliance before installing the
heater.

use 120 Volt, 60 Hz AC requires rewiring of the
heater. This should be done by a certified electrician
only, as with all wiring. To wire the heater for 120
Volt, 60 Hz AC, follow the alternate 120V wiring
method depicted in Figure 6. Additionally, the ignition
control module must be rewired. The wire from the
terminal marked IGN/240 must be removed from that
terminal and placed on the terminal marked IGN/120.
Electrical wiring must be in accordance with the
latest edition of the National Electric Code (NEC),
ANSI/National Fire Protection Association (NFPA)
70, unless local code requirements indicate otherwise.
Caution
Permanent damage to the gas valve will occur
if the following procedures are not followed.
8. If the gas supply pressure is less than required,
check for under-sized pipe between the meter and
the heater, a restrictive fitting, or an undersized
gas meter. Gas supply pressures to the heater are
listed in Table 4.
NOTE: The maximum inlet gas pressure must
not exceed the specified value. The minimum value
listed is for the purpose of input adjustment. Refer to
Table 4.
To wire the Laars Lite heater:
1. Wire the heater to a 120V or 240V /60 Hertz
(Hz) electrical source.
Table 4. Gas Supply Pressure Requirements
2. Connect the wires from the source to the leads on
the right side of the heater in the space behind the
ignition control (see Figure 8).

9. Before operating the heater, test the complete gas
supply system and all connections for leaks using
a soap solution. Do not use an open flame.
2F-2. Auxiliary Time Clock Wiring
(LLD or LLG)
If you install a time clock to control the filter
pump operation, it is recommended that the time clock
have its own low voltage (Fireman’s) switch to turn off
the heater before turning off the pump. The switch
should shut off the heater about 15 minutes before the
filter pump shuts off. This will allow for a more
efficient operation by removing any residual heat
contained in the heat exchanger back to the pool.
To install a time clock auxiliary switch into the
heater wires (see Figure 9):
Caution
Some leak test solutions (including soap and
water) may cause corrosion or stress cracking.
Rinse the piping with water after testing.
2E-2. Special Precautions for Propane
Gas (LLG Only)
1. Remove heater door.
Liquefied petroleum (LP) gas is heavier than air.
Therefore, do not install pool heaters using LP gas in
pits or locations where gas might collect. Locate
heaters a safe distance from LP gas storage and filling
equipment. Consult local codes and fire protection
authorities about specific installation restrictions.
2. Remove the factory installed wire between
terminals 1 and 2 on the terminal strip (see Figure
9).
3. Connect the wires from the time clock auxiliary
switch to the two terminals. Use American Wire
Gage (AWG) No. 14 gauge stranded copper wire
with a temperature rating of 221°F (105°C) or
greater.
2F. Electrical Wiring
2F-1. General Information (LLD Only)
Wiring connections must be made exactly as
shown in the wiring diagram found on the inside of the
heater (see Figures 6 and 7 for typical examples) and
must include a definite means of grounding. There is a
bonding lug on the right side of the heater, where a
bond wire must be attached.
The length of the wire between the heater and the
time clock should not exceed 10-15 feet (4.57 m). The
contact points of the time clock switch should be silver,
or a low resistance alloy.

be wired for remote operation. The CS-02 remote
control permits switching from one temperature
controller to the other and turning the heater on and
off from a remote location. The CS-04 includes the
same features as the CS-02 plus a remote tempera-
ture controller. Contact Teledyne Laars for further
information. Reference part numbers CS-02 and
CS-04.
An interrupt (on/off) type remote can be
connected by removing the jumper wire on the terminal
block located in the control compartment (see
Figure 6) and connecting the two wires from the
remote to the two terminals on the terminal block. This
type of remote control will turn the heater on or off,
but will not switch between the two temperature
controllers on the Flex-Temp control panel.

Laars Lite heater, except in Canada, however, it is
recommended and may be required by local codes.
To install a pressure relief valve, remove the 3/4
inch (19 mm) brass plug on the in/out header with the
valve (see Figure 16). The setting of the valve should
be at or below the lowest working pressure of filter
systemcomponents.
27. Attach the flue collector holddown clamps to the
clips located under the two center header bolts.
28. Replace the gap closures and tighten the screws
securely.
29. Re-cover the header sensors with fiberglass
insulation, and replace the insulation retainer.
2G-6. Adjusting the Pressure Switch
30. Double-check to make sure the wiring is not
pinched against sharp edges, or resting on the flue
collectorassembly.
Caution
The pressure switch should be adjusted to turn
the heater off when the pump is off. Setting
the switch to close at too low of a flow can
damage the appliance. Adjust the switch to
turn the heater off, not on.
31. Re-install rainshield assembly.
32. Replace the top assembly. Make sure the tabs are
outside the heater jacket. Fasten the top assembly
with the hex-head screws.
The pressure switch is preset at the factory for
activation at 2 psi (14 kPa). Adjust the pressure switch
only if any part of the filter system piping is 3 feet
(0.91 m) or more above the top of the heater jacket.
Do not adjust the pressure switch if the heater is
installed more than 15 feet (4.57 m) below or 6 feet
(1.83 m) above the pool surface. Consult your local
Teledyne Laars representative for recommendations.
On some installations, the piping from the heater
to the pool is very short. The back pressure could be
too low to trigger the pressure switch. If this happens,
it may be necessary to install a directional fitting or
elbows where the return line enters the pool. This will
increase back pressure enough for the heater to operate
properly.
33. Install plastic tie wraps on wiring.
34. Install heater door.
35. Reinstall the vent cap or drafthood, if one was
removed.
2G-3. Check Valve Installation
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.
2G-4. Chlorinators, Ozone Generators,
and Sanitizing Chemicals
Make sure the pool filter is clean before making
any pressure switch adjustment: A dirty filter will
restrict the water flow and the pressure switch cannot
be adjusted properly. To adjust the pressure switch:
The Teledyne Laars Lite heater is manufactured
with materials that are not compatible with high
concentrations of ozone, chlorine, bromine, or other
sanitizing chemicals. Heater damage caused by exces-
sive chemicals or improper ozonation is not covered by
the Teledyne Laars warranty. Be sure to adhere to the
following:
1. Turn the control panel rotary switch to OFF (see
Figure 17).
2. Turn filter pump on. If a two-speed pump is used,
make sure it is at high speed.
•
When ozone is injected upstream of the heater,
install an offgas mixing chamber, or an ozone

2G-7. Automatic Flow Control Valve
The automatic flow control valve maintains the
proper flow through the heater at rates up to approxi-
mately 125 Gallons Per Minute (GPM) (474 liters per
minute [LPM]). If the system filter-flow rate is higher
than approximately 125 GPM (474 LPM), install a
manual bypass valve (see Figure 18), then perform a
temperature rise test (see Section 2G-8) and adjust the
flow with the bypass valve until the proper temperature
rise is obtained.
Figure 17. Thermometer and pressure relief valve.
10. Subtract the first temperature reading (cold
water) from the second temperature reading
(heated water). The difference between the two
readings is the temperature rise. The temperature
rise should be within the range shown in Table 6.

11. If the temperature rise is below the minimum
range indicated, two possibilities arise:
1. Make sure the pool filter is clean.
2. Set the rotary switch on the temperature control
panel (see Figure 17) to OFF.
a. The supply gas volume is too low.
b. The system's water flow exceeds 125 GPM
(474 LPM), and requires a manual bypass
valve for proper operation (see Figure 19).
3. Turn the filter pump off.
4. Remove the drain plug located on the right-hand
side of the heater and replace it with a Pete's plug
(see Figure 16).
12. If the temperature rise is above the maximum,
there is not enough water flowing through the
heater. Check for clogging in the water filter or
restriction in the water pipes.
5. Insert a pocket thermometer (see Figure 16)
through the Pete's plug into the header.
6. Turn the filter pump on and wait 3 minutes. The
heater is turned off.
Caution
Operation with the temperature rise above
maximum or below the minimum can damage
the heater and may void the warranty.
7. Record the temperature indicated by the ther-
mometer (cold water).
8. Turn the heater ON following the lighting in-
structions found on the inside of the heater.
13. If the temperature rise is within the correct range,
complete the procedure as follows:

SECTION 3.
a) Model LLD Temperature Control
Operating Instructions
3A. General Information
With any new pool or spa installation, operate the
filter pump with the heater off long enough to com-
pletely clean the water. This will remove any installation
residue from the water. Clean the filter at the end of this
operation before starting the heater. When raising the
temperature of a cold pool, remove all time clock
settings. This lets the filter system and heater operate
continuously until the water reaches the temperature
setting on the temperature control. When that happens,
the heater will automatically shut off, but the filter pump
will keep running.
b) Model LLG Temperature Control
Figure 18. Temperature controls.
WARNINGS
Vent pipes, drafthoods, and heater tops get hot!
These surfaces can cause serious burns. Do not
touch these surfaces while the heater is in
operation. Adding a vent cap reduces the
temperature on the top.
For your safety, when starting the heater, keep
your head and face well away from the lower
firebox opening to prevent any risk of personal
injury.
Keep all objects off the top of the heater. Blocking
air flow could damage the heater, and may void
the warranty.

b. Wait 3 minutes, turn filter pump off.
c. Remove thermometer and Pete's plug.
d. Replace the drain plug.
3B. Lighting and Shutdown Procedures
NOTE: If your LP tank runs out of fuel, turn off
gas at the heater. After the tank is refilled, the heater
must be re-lit following the instructions found on the
inside of the heater. DO NOT attempt repairs on the
gas control or heater. Tampering is dangerous and
voids all warranties.
2G-9. Adjusting the Manual Bypass Valve
After the manual bypass valve is installed, use
the following procedures to adjust the bypass valve:
1. Clean pool filter.
2. Remove drain plug located on right-hand side of
heater and replace it with a Pete's plug.

3D. Seasonal Care
6. Use compressed air to blow out any standing
water remaining in the heat exchanger.
3D-1. Spring and Fall Operation
During periods when the pool is only going to be
used occasionally, turn the temperature control down
to the MIN setting. This prevents the pool from water
from becoming chilled, and maximizes the time re-
quired to raise the pool water back up to the desired
temperature.
7. Grease the threads in the drain plugs and reinstall
plugs, but do not tighten.
8. Disconnect the pressure switch copper tubing (see
Figure 21).

2. The drinking of alcoholic beverages before or
during spa or hot tub use can cause drowsiness
which could lead to unconsciousness, and subse-
quently result in drowning.
3D-3. Spring Start-up
To restart the heater in the Spring, have a profes-
sional service technician reassemble the heater as
follows:
1. Attach the copper tubing to the pressure switch
and fill the loop with SAE 50, non-detergent oil
(see Figure 21).
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) maxi-
mum.
2. Tighten the drain plugs.
3. Turn on the main gas supply valve to the heater,
outside the heater jacket.
4. Turn on the heater following the lighting instruc-
tions found on the inside of the heater.
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 4°F (-16°C).
3E. Water Chemistry
Proper chemical balances are necessary for
sanitary bathing conditions as well as ensuring your
heater's long life. Be sure to keep your chemical levels
within the values indicated in Table 7. Teledyne Laars
does not warrant heat exchangers damaged by corro-
sive chemical levels or excess dissolved solids in pool
or spa water.
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
For spas, it is also necessary to perform water
changes in addition to chemical treatment. It is recom-
mended to change the spa water every 60 days for light
usage and every 30 days if usage is heavy.
3F. 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.
1. Spa or hot tube 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.

anticoagulants) should not use spas or hot tubs.
discourage further adjustments.
4. Set the filter 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.
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:
5. 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.
6. During the winter or when on vacation for longer
than a week, shut down the heater by following
the shut-down instructions found on the inside of
the heater.
