12.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.

CAUTION

Some leak test solutions (including soap and water) may cause corrosion or stress cracking. Rinse the piping with water after testing.

2G-2. Special Precautions for Propane Gas

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.

2H. Electrical Power

2H-1.General Information

Wiring connections must be made exactly as shown in the wiring diagram found on the inside of the heater (see Figure 8 ). Grounding must be provided as required by the prevailing electrical code. A separate bonding wire MUST be provided as indicated in the following section

The heater comes factory-wired intended for use with 240 Volt, 60 Hz AC field electrical supply. To convert to 120 Volt, 60 Hz AC requires the changing of the fifteen- pin connector assembly on the component raceway. Remove the fifteen-pin connector from the receptacle located directly below the fan intake on the raceway. All the wires on the connector are red and the connector is marked "240V". The fifteen-pin connector will have two

wires that lead to a two position terminal block located next to the connector. Remove the two wires from the terminal block. Take the fifteen-pin connector assembly with the black wires from the installation and instructions box. It is marked "120V". Connect the two long wires to the two position terminal block. Either wire may be connected to either tab on the terminal block, the connections are not polarity sensitive. Plug the fifteen-pin connector into the receptacle. The connector is keyed so it will fit in only one orientation.

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

DO NOT connect power to the LX or LT pool heater from the load side of a filter pump relay or time clock.

To wire the Laars LX or LT heater:

1.Wire the heater to a 120V or 240V /60 Hertz (Hz) electrical source.

2.Connect the wires from the source to the leads on the right side of the heater in the space behind the raceway (see Figure 9).

NOTE: No external junction box is required.

2H-2. Bonding

The National Electrical Code and most other codes require that all metallic components of a pool structure, including reinforcing steel, metal fittings and above ground equipment be bonded together with a solid copper conductor not smaller than a number 8 wire. The heater, along with pumps and other such equipment must be connected to this bonding grid. A special labeled bonding lug is provided on the right side of the heater to accommodate this requirement.

2H-3. Auxiliary Time Clock Wiring

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 circuit, follow these instructions (see Figure 10):

1.Remove heater door.
