Page 12 2K-4. Pressure Relief Valve A pressure relief valve is mandatory in any installation in which the water flow can be shut off between the heater outlet and the pool/spa. A pressure relief valve is not supplied with the Hi-E2 in the United States; however, it may be required by local codes. A pressure relief valve must be provided in Canada. [...]

Hi-E2 Page 13 IMPORTANT : If an automatic chlorinator is being used, equip the chlorinator with an anti- siphoning device so that chlorine will not siphon into the heater after the pump shuts off. Wire an electric chlorinator so that it cannot operate unless the filter pump is running. If the chlorinator has an independent clock control, synchroniz[...]

Page 14 continued water flow and satisfactory operation of the system. 9. When the FlexTemp control stops calling for heat, the ignition control shuts off the gas valve and the flame goes out. 10. The ignition control continues to operate the combustion blower for a “post-purge” period, after which it is turned off. The process is repeated upon[...]

Hi-E2 Page 15 To adjust the pressure switch, proceed as follows (see Figure 23). The pool filter must be clean before making this adjustment. The heater does not have to be firing. 1. Turn the Flex Temp switch to OFF, and make sure the pressure switch is at its lowest setting. This is done by rotating the adjuster counterclockwise as far as it will[...]

Page 16 WARNING Do not attempt repairs on the gas control or appliance. Tampering is dangerous and voids all warranties.
