Do NOT use with storable pools. A permanently installed pool is constructed in or on the ground or in a building such that it cannot be readily disassembled for storage. A storable pool is constructed so that it is capable of being readily disassembled for storage and reassembled to its original integrity. Though this product is designed for outdoor use, it is strongly recommended to protect the electrical components from the weather. Select a well drained area, one that will not flood when it rains. It requires free circulation of air for cooling. Do not install in a damp or non-ventilated location. WARNING – It is required that licensed electricians do all electrical wiring. Risk of Electric Shock. Hazardous voltage can shock, burn, cause death or serious property damage. To reduce the risk of electric shock, do NOT use an extension cord to connect unit to electric supply. Provide a properly located outlet. All electrical wiring MUST be in conformance with applicable local and national codes and regulations. Before work- ing on this unit, turn off power supply to the heater. WARNING – To reduce the risk of electric shock replace damaged wiring immediately. Locate conduit to prevent abuse from lawn mowers, hedge trimmers and other equipment. WARNING – Failure to bond to pool structure will increase risk for electrocution and could result in injury or death. To reduce the risk of electric shock, the electrician must comply with installation in- structions and must bond the heater accordingly. In addition, the licensed electrician must also conform to local electrical codes for bonding requirements.

WARNING - To reduce the risk of entrapment hazards: • When suction outlets are less than a 18” x 23” equivalent, a minimum of two function- ing suction outlets per pump must be installed. Suction outlets in the same plane (i.e. floor or wall), must be installed a minimum of three feet (3’) [1 meter] apart, as mea- sured from near point to near point. • Dual suction outlets shall be placed in such locations and distances to avoid “dual blockage” by a user. • Dual suction fittings shall not be located on seating areas or on the backrest for such seating areas. • The maximum system flow rate shall not exceed the flow rating of any listed (per current revision of ASME/ANSI A112.19.8) suction outlet cover installed. • Never use the Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not securely attached. • Replace damaged, broken, cracked, missing, or not securely attached suction outlet components im- mediately. • Install two or more suction outlets per pump in accordance with latest APSP (formally NSPI) Stan- dards and CPSC guidelines. Follow all applicable National, State, and Local codes.

Failure to follow safety and operation instruc- tions could result in violent separation of pump components. Strainer cover must be properly secured to pump housing with strainer cover lock ring. Before servicing pool and spa circulation system, manual air relief valve must be in open position. Do not operate pool and spa circulation system if a system component is not assembled properly, damaged, or missing. Do not operate pool and spa circulation system unless filter air relief valve body is in locked position in filter upper body. WARNING – Never operate or test the circulation system at more than 40 PSI. WARNING – Fire and burn hazard. Motors operate at high temperatures and if they are not properly isolated from any flammable structures or foreign debris they can cause fires, which may cause severe personal injury or death. It is also necessary to allow the motor to cool for at least 20 minutes prior to maintenance to minimize the risk of burns. WARNING – Failure to install according to defined instructions may result in severe personal injury or death.

This feature is useful for preventing unauthorized users from manually adjusting the temperature settings higher than desired. On a new heater, the maximum allowed USE ONLY HAYWARD GENUINE REPLACEMENT PARTS temperature lock settings are initially set at the factory to 90°F for POOL mode, and 104°F for SPA mode. -
Page 12: Temperature Lock-Out
TEMPERATURE LOCK-OUT: The digital thermostat in this pool heater allows the user to lock the maximum temperature setting allowed. This feature is useful for preventing unauthorized users from manually adjusting the temperature settings higher than desired. On a new heater, the maximum allowed temperature lock settings are initially set at the factory to 90°F for POOL mode, and 104°F for SPA mode. To adjust these settings, use the following procedure: 1. Use the MODE button to put the heater in STANDBY mode. 2. Press and hold both the UP and DOWN buttons at the same time. 3. After 3 seconds, the thermostat enters maximum temperature lock adjustment mode. 4. The SPA indicator light illuminates and the numeric display shows the current SPA mode maximum temperature lock setting. Both the SPA indicator light and the numeric display flashes rapidly when in adjustment mode. 5. Use the UP and DOWN buttons to set the desired maximum temperature lock setting. When finished, press the MODE button. 6. The POOL indicator light illuminates and the numeric display shows the current POOL mode maximum temperature lock setting. Both the POOL indicator light and the numeric display flashes rapidly when in adjustment mode. 7. Use the UP and DOWN buttons to set the desired maximum temperature lock. When finished, press the MODE button. 8. The heater will return to STANDBY mode. FAHRENHEIT VERSUS CELSIUS: The temperature can be displayed in Fahrenheit or Celsius. TO change the display, use the “MODE” button to place the heater in “STANDBY”. Then press and hold the “UP” and “MODE” buttons until the display shows the °F/°C selection. Press the “DOWN” button to toggle between selections. To accept the selection, press the “MODE” button. If the user does not act, the selection will be automatically accepted after 60 seconds. WINTERIZATION: In moderate climates, the heater can continue to operate during short-term cold spells. Do not use the heater to maintain the water temperature just above freezing or for freeze protection. Care must be taken to avoid freeze-up in the heater. When it is used during freezing weather, the pump must run continuously. The heater is not warranted against freeze-ups. In regions where freezing temperatures are encountered, all water must be drained from the heater when it is out of service, to prevent damage to the heater and piping. Drain- ing the heat exchanger is recommended as part of the season’s shutdown procedures. -

Questions and answers
Hayward pool heater H350 starts up no code heats the water but there’s gas escaping through the top vent. I can’t figure out what it is and why.
Gas escaping through the top vent of a Hayward H350 pool heater while heating without any error codes could indicate incomplete combustion or improper venting. Possible causes include:
1. Blocked or restricted exhaust vent.
2. Improper air-to-gas mixture.
3. Dirty or misaligned burners.
4. Insufficient air supply to the combustion chamber.
5. Heat exchanger obstruction causing combustion gases to divert.
These issues may not trigger error codes but can lead to gas venting improperly. Inspection and servicing by a qualified technician is recommended.
