      Can I use a chlorinator or chemical feeder with this heater?
      – Follow the instructions provided with any automatic or manual chlorinator and chemical feeder. If a chlorinator is used, it must be installed down stream from the heater in the pool return line. Install a check valve between the heater outlet and chlorinator to prevent chlorine from siphoning back into the heater. All chemicals must be introduced and diluted into the pool or spa water before being circulated through the heater. Do not place chlorine tablets or bromine directly into the skimmer. High chemical concentrations may result when the pump is not running. High chemical concentrations cause very rapid corrosion of the heat exchanger. Such damage is not covered under warranty.

      Can I install this heater indoors?
      – NO, this heater is for outdoor use only. No draft hood available.

      Can this be used in high altitude areas?
      – NO, it can only be used at levels of 2000 feet or below.

      What size gas piping will I need for this heater?
      – Average size piping is ½" with proper gas pressure.

      Where can I install my heater?
      – The heater must be installed at least 5 feet away from the A/G pool wall and have proper ventilation on all sides, including the top.

      Can all states use this heater?
      – NO, Texas has EPA regulations that prevent sale of this product to residents of that state.

      What type of start up does this heater have?
      – The Hayward 100,00 BTU heater has an electronic direct spark ignition.

      Energy Saving Tips
      1. Keep your pool's heater thermostat at the coolest comfortable temperature. A pool thermometer will help you find the temperature that is perfect for you.
      2. Mark your comfortable setting on the heater thermostat to avoid costly overheating.
      3. Lower the heater thermostat setting to 70 degrees when pool won't be used for 3 or 4 days. For longer periods, shut the pool heater off.
      4. Any heated pool can benefit from a solar blanket cover. Two thirds of your pool's heat escapes through the water's surface. By using a solar pool blanket, you can help keep the heat in the pool, and cut your heating costs in half! For safety, remove pool blankets before swimming.

      Helpful Hints to properly size your new Hayward Induced Draft Heater...
      For propane heater installations:

      Basic Installation:
      100 lb. Propane Cylinder.
      Capacity: 23 1/2 Gallons of Propane
      Gallons Burned Per Hour: 1.1
      Approximate Running Time*: 15 Hours

      *Must have minimum of 7 gallons of liquid propane in tank to run the heater at 60º F.

      That is why the running time is 15 hours and not 21 hours (Capacity of tank - 7 gallons/1.1 = Approximate running time)

      This size cylinder is delivered to your home and the empty tank is removed.

      Deluxe Installation:
      500 lb. Propane Cylinder
      Capacity: 120 Gallons of Propane
      Approximate Running Time: 103 Hours

      Peace of mind.
      Should last the entire season.

      There are additional size tanks available. Consult your local supplier for information.

      Helpful Hint: It is highly recommended that you purchase a solar blanket in conjunction with your new heater for your pool or spa. It does not allow your heated pool water to dissipate as quickly and is designed to utilize the sun to help to heat you pool through solar rays.
      A solar blanket will reduce your gas costs and keep your pool warmer - longer! Consult your local pool professional.
