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 8 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 at least three
times.
5. Return the thermostat to a normal setting before
leaving the installation.
