Operation

Initial Operation

Your installation and setup is nearly complete. The first fire will
result in some smoke and smell being emitted from the appliance.
During the manufacturing of the product, paint, sealant and other
materials are used and when the unit is fired for the first time, the
temperature will cure these materials. When you fire this unit for
the first time, make certain that you've opened windows or use
any other ventilation to keep these fumes from building up. Once
at full operating temperature this will subside and then stop.
Your fireplace comes with decorative ceramic burner, log set and
panel set. These items off gas as part of their curing process. This
off gas can sometimes cause initial deposits on the glass. The
glass may need to be cleaned after the first few hours of operation.
See door removal and glass cleaning section.
Pilot Flame Adjustment
Pilot height is factory set when inlet is 7" WC. Adjustment may
be required if installation is not 7" WC. Refer to pilot flame height
drawing, figure 22b. The pilot flame runs directly at line pressure.
Variances in supply pressure can affect the size of the pilot flame.
Excessive pilot size can overheat the flame proving components.
Under-sized pilot flames will result in problems initializing or
maintaining the pilot flame or main burner flame, or not carrying
over to the main burner as intended. The pilot flame adjustment
is on the front of the valve. You need to turn on the fireplace
and then using remote control, turn down the flame height until
the main burner goes out, leaving only the pilot flame on. If you
reduce the pilot flame too much, the unit will go out and then try
to re-lite automatically.

Operation
Pilot adjustment is made with a flat screw driver turning it in
(clockwise) reduces the pilot flame size. Turning it out, (counter
clockwise) will increase the flame size. If the pilot is too height the
flame at the back right of burner can look too tall.
Figure 2 Sec.10
If the pilot flame is turned down too much, the flame will lift off the
sensor and shut the unit off. The flame should be adjusted until
it is not excessively large, but is large enough to operate the unit
in a reliable fashion.
