CHAPTER 4 - WATER HEATER START-UP
• Household water usage patterns will af-
fect water temperature at any faucet or
shower. Occasionally check temperature at
each point of use, then adjust thermostat
accordingly. Always recheck temperature
after adjusting thermostat.
• When hot water is used in repeated small
quantities, a “stacking” effect can develop
in the water heater. The upper layer of wa-
ter in tank can be hotter than lower layer,
resulting in very hot water coming out at
the faucet.
• It is therefore recommended to either lower
the thermostat setting or install automatic
mixing valves as indicated in these instruc-
tions in order to reduce water temperature
levels. Consult your installer or service tech-
nician.
NOTICE
4.3. Adjusting the Water Heater Thermostat
Water heater thermostat is factory set to its lowest
temperature. This may or may not be suitable for your
needs.
• Turn thermostat knob
clockwise to in-
crease water temperature.
• Turn thermostat knob counter-clockwise
to decrease
water temperature.
Bacteria can develop in the domestic water
system if certain minimum water tempera-
tures are not maintained. Failure to maintain
at least 140°F [60°C] domestic hot water tem-
perature (using the Antilegionella function
of your boiler, if any) can result in bacteria
development, which can result in serious in-
jury, or death.
• Check water temperature at a hot water faucet im-
mediately after first heating cycle. Further tempera-
ture adjustment may be necessary as water heating
system is used. Recheck water temperature at fau-
cet after adjustment.
• When adjusting thermostat, be sure boiler limit
control is set a minimum of 20ºF higher.
