an explosion or fire, and may result in severe
personal injury or death.

Setup and Adjustments

WARNING: Risk of Explosion or Fire. Do
not damage the regulator diaphragm if it is
necessary to replace the original gasket. Improper
installation or damage to the regulator diaphragm
may result in gas leaks, which can lead to an
explosion or fire and may result in severe personal
injury or death.

4. Carefully remove the regulator lid while gently
freeing it from the diaphragm and gasket. If the
gasket is damaged, carefully separate the gasket
from the diaphragm and use the new gasket
provided in the kit.

5. Use the original screws, or the screws provided in
the kit, to fasten the plate in position over the
diaphragm and gasket. Ensure the diaphragm is
smooth and not wrinkled at the mating surfaces.

6. Tighten the screws sufficiently to compress the
gasket. The regulator will be held open by the
plate.

7. Turn on the gas and electrical power supply.
Check for gas leaks using a soap solution.

8. Perform the Checkout section before leaving the
installation.
