Page 15ENGLISHJandy ® Pro Series, JXi ™ Gas-Fired Pool & Spa Heater | Installation & Operation ManualSection 4. Gas ConnectionsGas piping installation must be in accordance with thelatest edition of ANSI Z223.1 and all local codes. InCanada, the installation must be in accordance with CAN/CSA B149.1 and all local codes that apply.The heater must be isolated from the gas supply pipingsystem by closing the individual manual shut off valveduring any pressure testing of the gas supply piping systemat test pressure greater than or equal to 1/2 psi (3.5kPa).CAUTIONPermanent damage to the gas valve will occur if the installationprocedures are not followed correctly.WARNINGThe JXi pool and spa heaters are designed for use with eithernatural gas or LP gas. Check the rating plate on the front of thecombustion chamber to be sure that the heater is designed to usethe type of gas being supplied. CONVERTING THIS HEATER FORUSE WITH ANY OTHER FUEL TYPE IS NOT RECOMMENDEDBUT, WHEN NECESSARY, SHOULD ONLY BE PERFORMED BY ALICENSED AND QUALIFIED PROFESSIONAL, AND ONLY AFTERCONTACTING ZODIAC POOL SYSTEMS FOR THE PROPERINSTRUCTIONS AND CONVERSION KIT.All questions should be directed to the Zodiac customer servicecenter at 1-800-822-79334.1 Supply Gas RequirementsMaximum Equivalent Pipe LengthNatural Gas at 1050 btu per cubic footPropane Gas at 2500 btu per cubic foot3/4" 1" 1-1/4" 1-1/2" 2"Model NG LP NG LP NG LP NG LP NG LPJXi400 5 ft 20 ft 30 ft 60 ft 110 ft 260 ft 230 ft 560 ft 600 ft 600 ftJXi260 15 ft 40 ft 60 ft 150 ft 230 ft 590 ft 490 ft 600 ft 600 ftJXi200 30 ft 70 ft 100 ft 240 ft 380 ft 600 ft 600 ft• Numbers are for natural gas (0.60 Sp. Gr.) based on 1/2 inch (3.45 kPa) water column pressure drop. Check supply pressure with amanometer, and local code requirements for variations.• Check supply pressure and local code requirements before proceeding with installation.• Consider pipe fi ttings when determining gas pipe sizing. For every elbow used add three (3) feet to straight pipe length.• Table shows the minimum supply gas pipe size required. Larger pipe size can be used if required by local code or if desired.• It is critical that the incoming gas supply pressure at the heater is within the maximum and minimum pressure requirements. If the rangeof acceptable supply pressure is not provided, the gas supply system to the heater must be modified to meet pressure requirements.Table 2. Supply Gas Pipe Size Requirements• Refer to Table 2 for correct gas inlet piping lengthfrom the gas meter to the heater.• Check the gas meter to make sure it will supplyenough gas to the heater and any other appliancesusing the same gas supply. If unsure, contact yourlocal gas utility to confirm.• Install a manual gas shutoff valve outside the heaterbody for service and safety. Never install the shutoffvalve inside the body of the heater.• Install a sediment trap and union ahead of the gascontrols and outside the heater body. See Figure 6.• Do not use a restrictive gas cock.ATTENTIONDo not use fl exible appliance connectors on any gas connectionsunless the connector is CSA approved for outdoor installation, and ismarked with the BTUH capacity (which must be equal to or greaterthan the heater rated input) and the type of gas (Natural or LP). Also,any fl exible connectors, such as CSST buried underground must becertifi ed for underground installation and meet all applicable codes.Please note, use of fl exible connector still requires the installation ofa sediment trap per NFPA 54. See Figure 6.NOTE: The gas line from the meter is usually larger than thegas valve. Therefore, you will need to reduce connecting pipe asnecessary. Make this reduction as close to the heater as possible.PIPENIPPLESEDIMENT TRAPFigure 6. Manual Shut-off Valve and Sediment Trap |
