HOT WATER TEMPERATURE FLUCTUATES
1. Unbalanced pressure in waterlines
The added restriction caused by the Aquastar in the hot water system can result in uneven pressures between the cold and the hot. In such cases when mixing cold water at the tap, the lower hot water pressure may be overpowered by a much higher cold water pressure, which may cause the Aquastar burners to shut down. Make sure faucet aerators or shower heads are free of minerals. Do not add any flow restrictor to the shower head.
2.Cold water is mixing with the hot water between the AquaStar and the outlet
See #4 under “NO SPARK AT THE PILOT”.
3.Inlet water pressure is erratic due to inadequate supply water pressure or saturated pressure tank on well system
Check the inlet water pressure. On a private well, raise minimum pressure setting to 30 psi. Confirm that the pressure tank is not water logged.
4. Gas pressure is too low
See page 2 for correct specifications.
