WARNING: Risk of Explosion or Fire.
Follow this or an equivalent checkout procedure
after installation. Before leaving the installation,
verify that the gas valve functions properly and that
the system has no gas leaks. Gas leaks can lead to
an explosion or fire, and may result in severe
personal injury or death.
Make sure all components are functioning properly by
performing the following test.
1. Test all joints and connections for leaks with a rich
soap and water solution. If leaks occur, see Step
11 in the Installation section.
2. Close the main manual shutoff valve and wait at
least 5 minutes for unburned gas to escape from
the appliance, and then reopen the shutoff valve.
3. Turn on the main electrical power switch and close
the thermostat contacts. The appliance should
operate in accordance with the manufacturer’s
specified sequence of operation.
4. Turn the thermostat to a low dial setting to open
the contacts. All burner flames should be
extinguished. Repeat Steps 3 and 4 in this section
at least three times.
5. Return the thermostat to a normal setting before
leaving the installation.
