SAFETY

This product must be installed and serviced by authorized personnel, qualified in

pool/spa heater installation. Improper installation and/or operation can create carbon

monoxide gas and flue gases that can cause serious injury

, property damage, or death.

For indoor installations, as an additional measure of safety, Hayward strongly recom-

mends installation of suitable Carbon Monoxide (CO) detectors in the vicinity of this appli-

ance and in any adjacent occupied spaces. Improper installation and/or operation will

Section II. Heater Sizing Selecting the correct size heater: Factors influencing heater sizing include pool/spa size, average wind velocity, ambient temperature, and desired increase in temperature over ambient temperature, and desired increase in temperature over ambient. A pool/spa in a warm area with little or no wind will not require as large a heater as one in a cool windy location. Detailed sizing information is provided below. For a swimming pool: Section III. Installation 5.

Reversible Water Connections Heater Top Figure 5 Indoor installation and venting: The following installation and service clearances must be maintained from combustible materials. Indoor Installations Left Access Panels Top - 36” Front - Unobstructed Back - 6” Right side (Water side) - 12” Left side - 6” ROTATE HEAT EXCHANGER 180° For use on combustible floors. Do not install in a closet. DO NOT FLIP Figure 8 Air supply: Right Access Panels 12.

F Indoor Installation Vertical Venting—Negative Pressure: Figure 12 Locate the pool/spa heater as close as practical to a chimney and gas supply according to the Figures 12 and 13. Size vent according to the venting tables. The maximum vent height should not exceed 50’. The total vent length should not exceed one half of the total vertical vent height.
PAGE 6
Horizontal or Vertical Venting—Positive Pressure: The heater can be vented either horizontally or vertically with positive pressure vent system if one of the Special Gas Vent Systems listed in Figure 17 is used. Do not use a draft hood with this heater. The vent system must be installed in accordance with the National Gas Code ANSI Z223.1 or the CAN/CGA B149 Installation Codes, Local Codes and the Vent Manufacturer’s Instructions. See Figure 17 for permissible vent diameters for these heaters.

Gas supply and piping: Refer to the charts on Figure 25 for gas pipe sizing for low pressure natural gas, low pressure single state propane gas, and high pressure two stage propane gas systems. Sediment Trap Figure 26 All gas installations: The H-series heater is to be installed with a gas connection located on the left side. Insert the pipe to the gas valve through the grommet in the cabinet side.

exception of a three-way switching valve and an in-line chlorinator and associated check valve. Blockage of water flow from heater return to pool may result in fire or explosion causing property damage, personal injury, or loss of life. 1. The H-Series heater is equipped with CPVC SCH-80 flanged pipe nipples, union nuts, nitrile O-rings for use with 2” pipe connections. Figure 27 shows the method for installing these parts on the header.
PAGE 9
Installation above pool/spa surface: If the heater is installed less than three (3) feet above the surface of the pool/spa water, install eyeball fittings or directional flow fittings on the end of the return water line to the pool/spa to create adequate backpressure at the heater to operate the pressure safety switch when filter pump is running.
PAGE 10
Remote control connection: The heater is equipped for connection to an external 2-wire remote thermostat or a 3-wire remote switch. A 2-wire thermostat has its own temperature sensor for regulating water temperature. A 3-wire remote switch allows the “Pool” or “Spa” modes to be remotely selected. Connect remote wiring to the terminal block on the Control Module. For a 2-wire remote thermostat, connect one wire to the Pool terminal and the second wire to the 24 VAC terminal.

Section IV. Installer Check-out And Start-up General: Some of the following procedures will require the heater to be operating. Full lighting and shutdown instructions are included on the lighting instructions label secured inside the cabinet. The heater is automatically lit on each call for heat. Water must be flowing through the heater during operation. Check that the pump is operating and the system is filled with water and purged of all air prior to starting heater.
PAGE 12
Section V. Consumer Operation & Maintenance Procedures Installation below pool/spa surface: 1. Clean filter thoroughly. 2. Set heater thermostat to highest setting 3. Start filter pump. Make sure all air is out of water lines and complete system is full of water. 4. Turn filter pump off, adjust pressure switch control. (See “Water Pressure Switch” on Page 33). 5. Check pressure switch function by turning filter pump on and off causing heater to respond on or off.

Warning: Do not ingest alcohol or drugs during use or prior to using pool, spa, or hot tub. Ingestion of such intoxicants can cause drowsiness which can lead to unconsciousness, and subsequently result in drowning. Do not heat pool, spa, or hot tub water in excess of 104°F. A temperature of 100°F is considered safe for a healthy adult. Hotter water increases the risk of hyperthermia. Special caution is suggested for younger children.

5. 6. 7. 8. The igniter is turned off when flame is sensed or after 4 seconds. If flame is sensed for more than 60 seconds the control switches the blower to high speed. The blower prover switch, the temperature limit switches, the vent pressure switch, the water pressure switch, the water temperature sensors, and the flame sensor are constantly monitored during a call for heat to assure the heater is operating properly.

Section VI. Qualified Technician - Maintenance/Servicing General: IMPORTANT: Only qualified service technicians, having appropriate test equipment, should be allowed to service the heater. Bear in mind that all of the components that comprise the system have an effect on the heater operation.
PAGE 16
Burner inspection and cleaning: With the heater on, remove the front door and make a visual inspection of the main burners through the inspection window. The main burner flames should be about 1⁄2 to 2 inches in height and should not “lift” off the ports of the burners. See Figure 47. A normal flame is blue, without yellow tips. Yellow tips or a totally yellow or “lazy” flame may be an indication of a fuel-rich mixture due to restricted air openings, including spider nests in the burner and/or orifices.

PAGE 18
By-pass valve: The header houses an automatic by-pass valve. The valve provides proper water flow through the heat exchanger as the filter system water pressure varies. The valve assembly consists of a plunger, a spring, and a shaft. The plunger glides along the shaft as system water pressure compresses the spring. Very high acid or chlorine concentrations may damage the valve parts or very hard water may leave deposits on the shaft causing the valve to stick.

Section VII. Troubleshooting General: NOTE: These instructions are intended for the use of qualified personnel trained and experienced in the installation and servicing of this type of heating equipment and its related system components. Some states may require installation and service personnel to be licensed. Persons not qualified should not attempt to repair this equipment according to these instructions. WARNING: Never leave a jumper wire connected to keep a heater running.
