Laars 40000 Installation

Measure the width and depth of the heater, with the tape measure. Make a note of the measurements on a piece of paper. Multiply the width by the depth, to find the square footage of the base.

Measure the width and depth of a concrete block. Multiply the width by the depth, to obtain the square footage for an individual block.

Divide the square footage of the heater base by the square footage of the concrete block. The result is the number of cinder blocks needed for the base.

Arrange the cinder blocks on the floor, to create the base for the heater. Place your Laars pool heater on the cinder block base.

Connect the gas line from your home to the gas inlet valve on the heater. A licensed plumber should be hired to properly connect the gas line to the heater.

Run an electrical wire from your home's circuit panel to the heater. Open the back panel of the heater to access the electrical connections. Attach the electrical wire to the screw terminals, with the screwdriver.

Turn off the main breaker on the circuit panel. Attach the electrical wire to an available circuit inside of the panel. A licensed electrician should be hired to wire the heater to your circuit panel.

Attach the ends of the drain and supply pipes to the heater. Place a coupling nut on the end of the PVC supply and drain pipe. Insert the PVC coupling into the end of your supply pipe and drain pipe. Secure the PVC coupling by using PVC cement. Allow the PVC cement to set for at least 1 minute.

Place the O-ring into the groove of the PVC coupling. Attach the end of the PVC coupling onto the end of a threaded connection on the heater. Tighten the coupling onto each connection.
