Gas$Supply
The'supplied'Manual'Gas'Appliance'Shutoff'
Valve'must'be'installed'at'the'gas'connection'of'
the'water'heater'at'the'time'of'installation'(see'
diagram'to'the'left).
The'branch'gas'supply'line'to'the'water'heater'
should'be'a'minimum'of'3/4”'black'steel'pipe'
or'other'approved'gas'piping'material.
A'ground'joint'union'or'ANSI'design'certified'
semiErigid'or'flexible'gas'appliance'connector'
should'be'installed'in'the'gas'line'close'to'the'
water'heater.'The'National'Fuel'Gas'Code'
(NFGC)'ANSI'Z223.1'and'CAN'B149'code'
mandates'a'manual'gas'shutEoff'valve:'See'
NFGC'&'B149'for'complete'instructions.
If'flexible'connectors'are'used,'the'maximum'
length'shall'not'exceed'36”'(91'cm).
If'lever'type'gas'shut'offs'are'used,'they'shall'
be'approved'/'certified'gas'cocks.
Compound'used'on'the'threaded'joints'of'the'
gas'piping'must'be'of'the'type'resistant'to'the'
action'of'LP'gas.'Use'compound'sparingly'on'
male'threads'only.'
A'sediment'trap'should'be'installed'at'the'
bottom'of'the'gas'line.
Do'not'use'excessive'force'(over'31.5'ft'lbs.'
[42.7'Nm])'in'tightening'the'pipe,'particularly'if'
teflon'pipe'compound'is'used,'as'the'unit'may'
be'damaged.
The'inlet'gas'pressure'to'the'water'heater'must'
not'exceed'10.5”'w.c.'(2.6'kPa)'for'natural'or'
14”'w.c.'(3.5'kPa)'for'LP'gas.'For'purposes''
of'input'adjustment,'the'minimum'inlet'gas'

for'correction.
NOTICE:'To'ensure'proper'operation'of'the'
heater'the'gas'pipe'and'gas'meter'must'be'sized'
correctly.

Leak$Testing
The'water'heater'and'its'gas'connections'must'
be'leak'tested'at'normal'operating'pressures'
before'it'is'placed'in'operation.
$$'Turn'on'the'gas'shutEoff'valve(s)'to'the'

$$$Use'a'soapy'water'solution'to'test'for'
leaks'at'all'connections'and'fittings.'
Bubbles'indicate'a'gas'leak'that'must''
be'corrected.$
The'factory'connections'should'also'be'leak'
tested'after'the'water'heater'is'placed'in'
