WARNING
 DO NOT adjust any other DIP switches other than the ones that are indicated below.
 Turn off the power supply to the water heater before changing the DIP switch
settings.
 Failure to observe these warnings could result in carbon monoxide poisoning, severe
personal injury, or death.

Household Flow Rates
Taken from UPC 2006
 The flow rate through the water heater is limited to a
maximum of 6.6 GPM for the 110 model, 8.0 GPM for the 310
model, and 10.0 GPM for the 510 model.
 The temperature setting, along with the supply temperature
of the water will determine the flow rate output of the unit.
 Please refer to the temperature vs. gallons per minute charts
on p. 56 to determine the likely flow rates based on your local
ground water temperature and your desired outlet water
temperature.
 Refer to the right table for typical household plumbing fixture
flow rates to determine what the water heater can do in a
household application.
