WARNING: Fire or Explosion Hazard. Avoid accumulation
of unburned gas and resulting personal injury or
property damage by making sure the main burner
lights under all pilot burner flame conditions that
maintain the BASO in the On position. Follow the
procedure below to assure the location of the pilot
with respect to the main burner is acceptable.
To perform the turn down test with the Y99AB Test Kit (purchasable
from your BASO Gas Products authorized wholesaler):
1. Disconnect the thermocouple from the BASO safety shutoff device
and connect it to the test kit (see Figure 2). Hold the BASO in the
open position during this test using battery power from the test kit.
