When'the'water'heater'is'installed'above'3,280'feet'
(1,000m),'the'adjustment'of'DIP'switch'is'required'for'
high'altitude'installation.
Without'adjusting'the'DIP'switch,'the'water'heater'

How'to'adjust'the'DIP'switch'on'the'PCB'for'high'
altitude'installation:
● 'Check'the'altitude'(above'sea'level)'where'the'
water'heater'is'installed.
● 'If'the'altitude'is'more'than'3,280'feet'(1,000m),'
the'adjustment'of'DIP'switch'is'required.
● 'Turn'off'the'gas'shut'off'valve'and'water'shutoff'
valve.
● Remove'the'front'cover.
● 'Find'the'two'DIP'switches'located'at'the'top'right'
hand'side'of'the'PCB.''The'switch'labeled'"DIP'2"'
is'the'bottom'switch.
● 'Change'the'DIP'switch'#3'setting'of'DIP'2'to'
“ON”'position'if'the'water'heater'is'installed'
above'3,280'feet'(1,000m)'below'6,560'feet'
