Example, Metric units: If the heater’s
temperature control is set to 55°C, and the
temperature rise through the heater is 14°C, the outlet
temperature will be 69°C (55°C + 14°C). Set the
automatic reset high limit to 80°C (69°C + 11°C) and
set the manual reset high limit to 83°C (80°C + 3°C).
3.4 Adjustment for Minimum Input Rate
(models with modulating gas valve)
Adjust the red knob on the modulating gas valve
to the dial number for the desired water temperature
(see Table 7). Adjusting the red knob to number "1"
sets the gas flow rate to minimum. The control is
factory set at "2" which is satisfactory for most
installations.
