GAS SUPPLY AND PIPING (CONT.)
2. Install a drip leg (if not already incorporated as part of the water
heater) as shown. The drip leg must be no less than 3 inches long for
the accumulation of dirt, foreign material and water droplets.
3. Install a ground joint union between the gas valve/thermostat and the
manual shutoff valve. This is to allow easy removal of the gas valve/
thermostat.
IMPORTANT
: Refer to the "Gas Pressure Testing" section on this page before
pressure testing the gas lines.
4.
Turn the gas supply on and check for leaks. Use a chloride-free soap
and water solution (bubbles forming indicate a leak) or other approved
method.
Do not use an open flame. ALL LEAKS MUST BE FIXED
IMMEDIATELY.
DANGER
DO NOT USE AN OPEN FLAME OR ANY KIND OF SPARK TO CHECK
GAS PIPING FOR LEAKS. IF LEAKING GAS IS PRESENT, AN
EXPLOSION OR FIRE MAY RESULT CAUSING PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH.
IMPORTANT
: This water heater’s gas controls and its gas connection
must be leak tested before placing the appliance in operation.
IMPORTANT:
Air may be present in the gas lines and could prevent the
pilot from lighting on initial start-up. The gas lines should be purged of air
by a qualified service technician after installation of the gas piping system.
The gas supply pressure must not exceed the maximum supply pressure as
stated on the water heater’s data plate. The minimum supply pressure is
for the purpose of input adjustment
GAS PRESSURE TESTING
IMPORTANT: Subjecting the gas valve/thermostat to pressures
exceeding 14” W.C. (1/2 psi, 3.7 kPa) may cause damage resulting in
an extremely hazardous condition.
•
If the code requires the gas lines to be tested at a pressure exceeding
14” W.C., the water heater and its manual shutoff valve must be
disconnected
from the gas supply piping system and the line
capped.
•
If the gas lines are to be tested at a pressure less than 14” W.C. the
water heater must be
isolated
from the gas supply piping system by
closing its manual shutoff valve.
A U.L. RECOGNIZED FUEL GAS AND CO DETECTOR(S) ARE
RECOMMENDED IN ALL APPLICATIONS AND THEIR INSTALLATION
SHOULD BE IN ACCORDANCE WITH THE MANUFACTURER’S
RECOMMENDATIONS AND/OR LOCAL LAWS, RULES, REGULATIONS,
OR CUSTOMS.
