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
soap solution.
2. For models H43A_ and H43B_, close the shutoff
valve and wait at least 5 minutes for unburned
gas to escape from the appliance. Reopen the
shutoff valve.
For Model H43G_, close the valve. Pilot and the
main burner gas are shut off when the valve is in
the Off position. To turn the valve off, push in the
handle and turn it to the Off position while holding
the handle in (see Figure 2 for handle positions).
Wait at least 5 minutes for unburned gas to
escape from the appliance.

3. Turn the handle to the pilot position (see handle
on the valve).
4. Push the reset button down and light the pilot
burner. Continue to hold down the reset button
for 30 to 45 seconds or until the pilot remains
burning when the reset button or handle is
released.
5. Turn the handle to the On position. The main
burner should be ignited by the pilot burner.
6. Throttle between On and Pilot position only (if the
H43 manual valve is used to throttle the main
burner).
Note: In the Off position, the valve shuts off
both the pilot and the main burner gas. For
Models H43A__ or H43B_, turn off by pulling the
lock button and the handle to Off. H43G_ models
do not have a lock button.
7. Adjust the pilot flame (on valves that provide pilot
adjustment) by removing the slotted pipe plug
and turning the inner screw to the right to
decrease, or to the left to increase, the pilot
burner gas. Replace the slotted pipe plug and
tighten it securely to avoid any gas leakage.
8. Check the millivoltage (mV) output of the
thermocouple and the milliampere (mA) dropout
range of the BASO power unit to be sure the
meet the values in. Step-by-step procedures for
these checks are included with the Y99AB-4
BASO Test Kit Application Note.
9. Observe at least three complete operating cycles
to make sure that all components are functioning
properly.
10. Reset the thermostat to the desired setting before
leaving the installation.
