CHECKING THE BURNER FLAME

In normal operation at full rate after 15 minutes, the following ﬂame appearances should be observed:

Figure 32 - Correct Appearance of Rear Flames of Berkley Oak

Burner will have a random pattern of yellow flames as shown in Figure 32. There should be glowing embers on the front burner. Note: The front ﬂames and embers will be an opaque orange color during the burn off time.

OPERATING INSTRUCTIONS

Avoid any drafts that alter burner ﬂame patterns. Do not allow fans to blow directly into the fireplace. Do not place a blower inside the burn area of the firebox. Ceiling fans may create drafts that alter flame patterns. Sooting and improper burning will result.

During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, films or bonding agents. These chemicals are not harmful, but may produce annoying smoke and smells as they are burned off during the initial operation of the appliance, possibly causing headaches or eye or lung irritation. This is a normal and temporary occurrence.

The initial break-in operation should last four hours with the burner at the highest setting. Provide maximum ventilation by opening windows or doors to allow odors to dissipate. Any odors remaining after this initial break-in will be slight and will disappear with continued use.

This appliance must not be used with glass doors in the closed position. This can lead to pilot outages and severe sooting outside the fireplace. See Figure 3, page 10.
