the AquaStar’s outlet pipe with your hand) and at the tap.
If these two are very different, check for mixing valve or
plumbing crossover (see “MAIN BURNERS WILL NOT
IGNITE...” paragraph #6).
6. Parts in water flow valve are corroded so that the
gas passage is not fully opening.
Contact your service person or Controlled Energy.
HOT WATER TEMPERA TURE 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 notadd any flow restrictor to the shower head.2. 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.
3. Cold water is mixing with the hot water between
the AquaStar and the outlet
See #6 under “MAIN BURNERS DO NOT IGNITE WHEN
HOT WATER TURNED ON”.
4 . Insufficient gas pressure
Note required gas pressures (page 2) and consult gas
service person.
