3.3.7.1 Manifold pressure regulator adjustment
The manifold pressure regulator controls gas input and flame height, and is pre-adjusted at the
factory. No further adjustment is required. Manifold pressure can be verified only (see Figure 2)
.
3.3.7.2 Pilot adjustment
For proper operation, the pilot and main burner flames must be steady and not lifting off or floating.
The top 3/8” – 1/2” (10-13mm) of the thermopile should be engulfed by the pilot flame. The pilot
flame adjustment should be performed by a qualified service person only. To adjust the pilot flame,
turn the pilot adjustment screw counter-clockwise to increase and clockwise to decrease the flame.
Ensure that the pilot flame completely engulfs the thermopile (see below).
