CAUTION: Always use one 7/16” open end wrench and one large pliers or vice grips tool to hold, loosen and
tighten pilot hood base to prevent damage to pilot mount bracket.
7. While holding the pilot base body with large vice grips tightly, loosen the pilot’s hex-shaped base using a 7/16” open end
wrench. Rotate counter clock-wise ¼ turn to loosen.
8. Pilot arrives from the factory set for natural gas. Push natural gas/LP adjustment clip inward all the way to set it for LP. See
detail view, below. If you see “NAT” printing on the adjustment clip, this indicates that the pilot is set to burn natural gas. Push
the clip in so that “NAT” is not visible.
9. Tighten down hex-shaped base of pilot using a 7/16” open end wrench.
10. Install the airbox and both rear and front burners in their original locations and positions and secure down using screws you
removed earlier.
11. Make certain front burner is running parallel to front face of unit positioned properly so that the pilot hood pointing to the left
is pointed properly toward the burner’s flame propagation ports.
12. Make certain rear burner is positioned properly so that the pilot hood pointing to the back is pointed properly toward the
burner’s flame propagation holes.
13. Next, the pressure regulator will be changed. To do this, first remove the left-side access panel mounted to the left outer skin
of the unit and lay down gently without disconnecting any wires of internal components.
Warning: Do not force. Excessive
force may damage internal wiring components.
14. See diagrams below and identify the pressure regulator on the valve body. Remove the left side controls access panel. Gas
valve and the pressure regulator mounted on the gas valve are accessible through the opening on the left side.
15. Shut off the gas supply to the valve and shut down the electric supply.
Note: Be careful when removing or tightening the screw on the back of the pressure regulator. The screw location is difficult
to access and care must be taken to ensure a proper seal when tightened
