Natural Gas Water
- Safety and Maintenance
Your natural gas water heater requires very little
maintenance to keep it running safely and reliably for many years.
Reading the manufacturer’s instructions for specific operating and
maintenance procedures is essential.
Know where your water supply valve and gas valve are
on your water heater. In case of a leak you can turn the water and gas
burner off promptly. Ensure your gas valve is turned off whenever you
turn the water supply off.
Hint: the water supply valve is usually on the cold
water pipe near the top of the tank. The valve looks like a tap and may need
to be turned several times to shut off the cold water. The gas valve can
usually be found on the gas black or copper piping that comes vertically
down to the bottom of the unit. A small wrench will be needed to give the
valve a ¼ turn.

the tank as it could slip and cover a control or air intake

heater or a thermostatic valve on each hot water tap and showerhead in
