Comprehensive Guide: How to Connect a Propane Pool Heater

Connecting a propane pool heater can be a straightforward process, but it requires attention to detail and adherence to safety protocols. This comprehensive guide will walk you through the step-by-step process of properly connecting a propane pool heater, covering everything from placement and plumbing to power and gas connections.

Placement Considerations

When installing a propane pool heater, it’s crucial to choose the right location. The heater should be placed on a non-combustible surface, such as a concrete slab, with at least 2-3 feet of clear space all around. This ensures adequate airflow and prevents any potential fire hazards. It’s important to avoid placing the heater indoors or near any window openings or air intakes for the house, as this could lead to dangerous gas buildup. Additionally, the area above the heater should be clear of any overhanging structures to allow for proper ventilation.

Plumbing Connections

Connecting the propane pool heater to the pool’s plumbing system requires the use of schedule 40 PVC pipes. First, you’ll need to cut the return pipe after it has exited the filter. Then, using the schedule 40 PVC, connect the pipes in and out of the heater, ensuring a secure and leak-free connection. Finally, reconnect the exit pipe back to the return line. It’s important to note that any chlorinators should be moved downstream, after the heater and at ground level, to prevent corrosive fumes from backing up into the heater.

Electrical Power Connection

Propane pool heaters can be wired to either a 220-volt or 110-volt power source, depending on the specific model. It’s crucial to follow the instructions provided with the heater to ensure proper electrical connections. Alternatively, some propane pool heaters are designed as millivolt heaters, which do not require a dedicated power supply. These heaters can tap into the power from the pool’s timeclock or pump switch.

Propane Gas Connection

Connecting the propane gas supply to the pool heater is a crucial step. Start by contacting a local propane provider and requesting a quote for installing the necessary propane tanks and making the connection to the new heater. Be sure to provide the output in BTUs (British Thermal Units) of the heater, which can be found in the model number (e.g., a model 250 produces 250,000 BTUs, and a model 400 produces 400,000 BTUs). The size of the heater will determine the size of the propane tank and regulators required. The propane company will advise you on the best tank size for your specific needs. Once the tank and connections are in place, the delivery trucks can top off your propane tank, or you can call them for a refill as needed.

Technical Specifications

To ensure a safe and efficient installation, it’s essential to adhere to the following technical specifications:

  • Propane heaters should be placed on a non-combustible surface, with 2-3 feet of clear space all around.
  • Use schedule 40 PVC for all plumbing connections.
  • Connect the heater output line directly to the return pipe.
  • Propane pool heaters can be wired to either a 220-volt or 110-volt power source.
  • The propane tank size is determined by the heater’s output in BTUs.

DIY Steps

If you’re comfortable with DIY projects, you can follow these steps to connect your propane pool heater:

  1. Prepare a level, non-combustible surface, such as a concrete slab, for the heater’s placement.
  2. Measure and cut the PVC pipe to fit a PVC elbow joint on the water line.
  3. Connect the heater’s output line directly to the return pipe.
  4. Connect the heater to an electrical source, or hire a licensed electrician if necessary.
  5. Turn the propane valves to the “ON” position and light the heater according to the manufacturer’s instructions.

Remember, safety should always be the top priority when working with propane and electrical systems. If you’re unsure about any aspect of the installation process, it’s best to consult a professional.
