INSTALLATION
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.
