“OFF’* *, and never turn the gas “ON” before the tank is

Ф Combustion products contain water vapor which can con­
dense on the cooler surfaces of the tank. Droplets form and
drip into the fire or run on the floor. This is common at
the time of startup after installation and when incoming
water is cold.
Water in the water heater bottom or on the floor may be
from condensation, loose connections, or the relief valve.
DO NOT replace the water heater until a fiiU mspection
of all possible water sources is made and necessary correc­
tive steps taken. Leakage from other appliances, water
lines, or ground seepage should also be checked.
NOTE: To check where threaded portion enters tank,
insert cotton swab between jacket opening and fitting.
If cotton Is wet, follow “Draining” instractions in the
"Service and Adjustment” section and then remove fit­
ting. Put pipe dope or teflon tape on the threads and
replace. Then follow “Filling the Water Heater”
instructions in the “InstaUation Instructions” section.
