I-Series Indoor Gas Fireplace

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 an insulated porcelain panel set. This
item can 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 for NG / 11" WC for
LP. Adjustment may be required if installation is not 7" WC for NG
/ 11" WC for LP. 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 high 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.
