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 6 in the Installation section.
2. Close the main upstream shutoff valve and the
B valve (applications with a B valve only) and
wait at least 5 minutes for unburned gas to
escape from the appliance, then reopen the
valves.
3. Push the reset button and light the pilot burner.
Continue to hold the reset button for
30 to 45 seconds or until the pilot remains
burning when the reset button is released.
4. Check the millivoltage output of the thermocouple
and the milliampere dropout range of the BASO
power unit to be sure they meet the values in
Table 1 and Table 2. Step-by-step procedures for
these checks are included with the Y99AB-4
BASO Test Kit Application Note
(Part No. 24-8711-838).
5. Observe at least three complete operating cycles
to make sure that all components are functioning
properly.
6. Reset the thermostat to the desired setting before
leaving the installation.
