Warranty –
Factory warranty (shipped with unit) does not apply to units improperly installed or improperly operated.
Experience has shown that improper installation or system design, rather than faulty equipment, is the cause of most operating problems.

1. Improper maintenance of pool water chemistry resulting in high water hardness and high alkalinity that results in a lime scale build up in the copper tube is not the fault of the equipment and is not covered under the manufacturer’s warranty (see Facts About Water Chemistry in the EnergyRite Service Manual).
2. Excessive pitting and erosion on the inside of the copper tube may be caused by too much water velocity through the tubes and is not covered by the manufacturer’s warranty (see Water Connections in the Energy Rite Installation and Operation Manual).

Improper installation, adjustment, alteration, service or maintenance can cause injury or property damage. Refer to this manual for assistance or additional information, consult a qualified installer, service agency or the gas supplier.

Maintenance procedures
Pool heater must be serviced and maintained

The pool heater must be inspected and started annually at the beginning of the heating season by a qualified service technician. In addition, the maintenance and care of the pool  heater designated on page 5 of this manual and explained on pages 6 and 7 must be performed to assure maximum pool heater efficiency and reliability. Failure to service and  maintain the pool heater and system could result in equipment failure, causing possible severe personal injury, death, or substantial property damage.

The following information provides detailed instructions for completing the maintenance items listed in the maintenance schedule on page 5. In addition to this maintenance, the pool heater must be serviced and started up at the beginning of each heating season by a qualified service technician.

Check pool heater area

To prevent potential of severe personal injury, death, or substantial property damage, eliminate all materials discussed below from the pool heater vicinity and the vicinity of the pool heater combustion air inlet. If contaminants are found:
Remove products immediately from the area. If they have been there for an extended period, call a qualified service technician to inspect the pool heater for possible damage from acid corrosion.
If products cannot be removed, immediately call a qualified service technician to re-pipe vent and air piping and locate vent termination/air intake away from contaminated areas.

1. Combustible/flammable materials — Do not store combustible materials, gasoline or any other flammable vapors or liquids near the pool heater. Remove immediately if found.
2. Air contaminants — Products containing chlorine or fluorine, if allowed to contaminate the pool heater intake air, will cause acidic condensate in the pool heater. This will cause significant damage to the pool heater if allowed to continue.

Be sure to shut the pool heater OFF when backwashing the filter.

Check vent piping

1. Visually inspect the flue gas vent piping for any signs of blockage, leakage, or deterioration of the piping. Notify your qualified service technician at once if you find any problems.

Failure to inspect the vent system as noted above and have it repaired by a qualified service technician can result in vent system failure, causing severe personal injury or death.

Check air inlet piping (if applicable)

1. Visually inspect the air inlet elbow to be sure it is unobstructed. Inspect the entire length of air piping to ensure piping is intact and all joints are properly sealed.
2. Call your qualified service technician if you notice any problems.

Check relief valve (if applicable)

1. Inspect the pool heater relief valve and the relief valve discharge pipe for signs of weeping or leakage.
2. If the relief valve often weeps, immediately contact your qualified service technician to inspect the pool heater and system.

Test low water cutoff (if installed)

1. If the system is equipped with a low water cutoff, test the low water cutoff periodically during the heating season, following the low water cutoff manufacturer’s instructions.

Reset button (low water cutoff)

1. Testing the low water cutoff shuts the unit off. Press the RESET button on the low water cutoff to turn the unit back on.

Check pool heater piping (gas and water)

1. Remove the pool heater front access door and perform a gas leak inspection per steps 1 through 6 of the Operating Instructions on page 8. If gas odor or leak is detected,  immediately shut down the pool heater following the procedures on page 8. Call a qualified service technician.
2. Visually inspect for leaks around water piping.
   Also inspect the circulators, relief valve, and fittings. Immediately call a qualified service technician to repair any leaks.

Have leaks fixed at once by a qualified service technician. Failure to comply could result in severe personal injury, death, or substantial property damage.

3. Replace the front access door.

Operate relief valve (if applicable)

1. Before proceeding, verify that the relief valve outlet has been piped to a safe place of discharge, avoiding any possibility of scalding from hot water.

To avoid water damage or scalding due to valve operation, a metal discharge line must be connected to the relief valve outlet and run to a safe place of disposal. This discharge line must be installed by a qualified heating installer or service technician in accordance with the instructions in the Energy Rite Installation and Operation Manual. The discharge line must be terminated so as to eliminate possibility of severe burns or property damage should the valve discharge.

2. Read the pool heater pressure/temperature gauge to make sure the system is pressurized. Lift the relief valve top lever slightly, allowing water to relieve through the valve and discharge piping.
3. If water flows freely, release the lever and allow the valve to seat. Watch the end of the relief valve discharge pipe to ensure that the valve does not weep after the line has had time to drain. If the valve weeps, lift the seat again to attempt to clean the valve seat. If the valve continues to weep afterwards, contact your qualified service technician to inspect the valve and system.
4. If water does not flow from the valve when you lift the lever completely, the valve or discharge line may be blocked. Immediately shut down the pool heater, following the operating instructions on page 8 of this manual. Call your qualified service technician to inspect the pool heater and system.

Shut pool heater down

1. Follow “To Turn Off Gas to Appliance” on page 8 of this manual.
2. Do not drain the system unless exposure to freezing temperatures will occur.
