ADJUSTMENT
10.1 PRESSURE ADJUSTMENT
Check Pressure Readings:
Inlet pressure can be checked by turning screw (A) counter-clockwise 2 or 3
turns and then placing pressure gauge tubing over the test point. Gauge should
readas described on the chart below. Check with main burner operating on
"HI".
Outlet pressure can be checked the same as above using screw (B). Gauge
should read as described on the chart below. Check with main burner
operating on "HI".
AFTER TAKING PRESSURE READINGS, BE SURE TO TURN SCREWS CLOCKWISE FIRMLY TO RESEAL.
DO NOT OVERTORQUE.
Leak test with a soap and water solution.
Prior to pilot adjustment, ensure that the pilot
assembly has not been painted. If overspray or
painting of the pilot assembly has occurred
remove the paint from the pilot assembly, or replace. Fine emery cloth or sandpaper can be used to remove
the paint from the pilot hood, electrode and fl ame sensor.
10.2 VENTURI ADJUSTMENT
This appliance has an air shutter that has been factory set open according
to the chart below:
Regardless of venturi orientation, closing the air shutter will cause a more
yellow flame, but can lead to carboning. Opening the air shutter will cause a
more blue flame, but can cause flame lifting from the burner ports. The
flame may not appear yellow immediately; allow 15 to 30 minutes for the
final flame colour to be established.
AIR SHUTTER ADJUSTMENT MUST ONLY BE DONE BY A QUALIFIED
INSTALLER!
To access the air shutter, remove the control access panel, remove the glass door assembly and carefully remove
the log set. Remove the four screws attached to the burner pan. Slide the burner pan to the left roughly 1" (25mm)
then lift up.
Air shutters have been factory set open according to the Venturi
Adjustment Chart. These settings are for (maximum) horizontal
termination. Adjustment may be required depending on fuel type,
vent confi guration and altitude.
