Gas Pressure Testing
Important: This water heater and its gas connection must
be leak tested before placing the appliance in operation.
• If the code requires the gas lines to be tested at
a pressure of 14” W.C. or greater, the water heater
and its manual shut-off 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 shut-off valve.
Nationally listed/recognized fuel gas and carbon
monoxide(CO) detectors are recommended in
all applications and should be installed using the
manufacturer’s instructions and local codes, rules, or
regulations.
Note: Air may be present in the gas lines and could prevent
the burner 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.
