NOTICE:'The'water'heater'may'not'
operate'unless'the'above'procedure'is'
followed'correctly.
WARNING:$Failure$to$
follow$these$instructions$
while$draining$the$water$
heater$can$cause$serious$
damage$to$the$water$heater$
as$well$as$personal$injury,$
including$scalding.
NOTICE:$DO$NOT$
unplug$the$electric$
power$supply$cord$for$
freeze$protection.
Care$and$cleaning$of$the$water$heater:
Freeze$Protection
Where'the'water'heater'may'be'exposed'to'
freezing'conditions,'even'for'a'short'period'of'
time,'be'sure'to'drain'all'water'from'the'unit'
as'instructed'above.
Exposure'to'freezing'conditions'can'occur'
from'down'draft'of'venting'system'or'from'
installation'in'areas'exposed'to'cold'air.
The'water'heater'is'equipped'with'a'Freeze'
Protection'Electric'Heater.'As'long'as'electricity'
is'supplied'to'the'water'heater,'it'prevents'
freezing'inside'the'water'heater'down'to'an'
ambient'temperature'of'approximately''
minus'E30°F'(E34°C)'(without'wind'
conditions).
This'device'only'protects'the'internal'
components'of'the'water'heater.'It'does'NOT'
protect'piping'and'valves.'Therefore,'piping'
and'valves'should'be'wrapped'with'insulation'
material'as'instructed'on'page'23.
Another'method'of'freeze'prevention'is'by'
running'a'small'volume'of'water.'Running'
water'will'protect'the'water'heater,'piping''
and'valves.
Follow'the'steps'below'to'ensure'proper'water'
flow'through'the'water'heater'and'piping:
$$Turn'off'the'switch'on'the'remote'control.
''Close'the'gas'shutEoff'valve.
''Open'the'hot'water'faucet'slightly'until'a'
stream'of'approximately'1/8”'(.32'cm)'is'
flowing.'Be'sure'to'check'the'flow'
periodically.
