Things to tell the gas customer:
1. Show the customer the vent or vent assembly or vent
tube. Stress that this opening must remain unobstructed
at all times. Tell the customer to check the vent opening
after a freezing rain, sleet storm or snow to make sure
ice has not formed in the vent.

The customer should close this valve immediately if gas
is smelled, appliance pilot lights fail to stay on or appear
higher than usual or any other abnormal situation occurs.
3. Tell the customer to call your company to service the
regulator if the regulator vents gas or a leak develops in
the system. Only a qualified gas service person should
install or service the regulator.
4. Tell the customer to call your company to have a leak
check performed if the gas supply has been shutoff
or interrupted for any reason. A leak check must be
performed by a qualified gas service person on the piping
system immediately after turning on the gas supply.
