Step 11:
Make Gas Connec ons
The Gas Water Heater Hook-Up Kit
(available at Lowe’s®) includes a fl ex-
ible gas connector with compression
fi  ngs to connect the home’s gas line
to the water heater’s gas control valve.
Follow the kit’s installa on instruc ons
to a ach the fl exible gas connector.
Figure 31 - Flexible gas line connector.
Once you’ve made the gas connec-
 ons, use a small, so -bristled brush
to apply a hand dishwashing soap
and water mixture or children’s soap
bubbles (1 part soap to 15 parts water)
to all connec on points of the gas line
and fl exible gas connector (if used).
Make sure to generously coat all the
connec ons and check for gas leaks
(which will appear as small bubbles).
If any leaks are detected, turn the gas
supply off ,  ghten the leaking connec-
 on and re-check.
