1. Loosen the inlet (IN) pressure tap by turning screw
counterclockwise. See (A).
2. Attach manometer using a 1/4” (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” (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.
INLET PRESSURE TEST
NOTE: 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.

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
WARNING: VENTURI ADJUSTMENT MUST BE DONE BY A QUALIFIED SERVICE TECHNICIAN.
WARNING: To avoid property damage or personal injury, allow ample time to cool before making any
adjustments.
CAUTION: 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.
During the initial installation, the air shutter opening should be checked to be certain that the shutter is set
correctly at 0” to 1/8” natural gas or 1/8” to 1/4” LP gas. NOTE: For altitudes above 5,000 ft., some variations may
be required.
Be sure burner and logs are properly installed. After burner has been properly installed and operated for 2-3 hours,
small additional adjustments to the air shutter may be necessary for final flame appearance. These small shutter
adjustments can be made by the following procedure. NOTE: Very small changes in shutter settings make major
changes in flame appearance.
1. Air shutter controls are located at the bottom of the fireplace next to the valve assembly.
