1. Loosen the inlet (IN) pressure tap by turning screw
counterclockwise. See (A).
2. Attach manometer using a 1/4 in (6 mm) I.D. hose. Light
pilot and burner. Check pressure to ensure it is between the
minimum and maximum recommended pressure settings.
3. Turn off burner and pilot.
4. Disconnect hose and tighten the inlet (IN) pressure tap by
turning screw clockwise. Screw should be snug. Do not over
tighten.
5. Relight pilot and burner. Then reattach manometer to the
inlet pressure tap (A) to verify the tap is completely sealed.
Manometer should read no pressure.
Manifold Pressure Test
1. Light pilot.
2. Loosen manifold (OUT) pressure tap by turning screw counter-clockwise. See (B) in Figure 11.1.
3. Attach manometer to pressure tap using a 1/4 in (6 mm) I.D. hose.
4. Light burner. Check manometer reading.
5. Turn burner and pilot off.
6. Disconnect manometer hose and tighten the manifold (OUT) pressure tap by turning screw clockwise. Screw should be
snug. Do not over tighten.
7. Attach the manometer to the manifold pressure tap (B) to verify it is completely sealed. The manometer should read no
pressure when pilot and burner are on.
Make sure to apply these incoming pressure test with all other gas fireplaces on, or at full capacity in the house for
proper pressure reading.
Inlet Pressure Test
If the inlet pressure reading is too high or too low, contact the gas company. Only a qualified gas service
technician should adjust incoming gas pressure.

Burner Flame Adjustments
Burner flame appearance and characteristics are affected by altitude, fuel quality, venting configuration, and other factors.
After installation, additional adjustments may be required to achieve optimum flame appearance and visual aesthetics.
Gas Flame Adjustment
To avoid property damage or personal injury, allow ample time to cool before making any adjustments.
VENTURI ADJUSTMENT MUST BE DONE BY A QUALIFIED SERVICE TECHNICIAN.
