Flame Appearance - Monessen Hearth Lyric Series Installation & Owner's Manual

DO NOT sprinkle volcanic rocks around the
pilot or near the burners. This may cause
sooting. Place volcanic rocks only on the
floor of the fireplace.
During initial opearation of the new heater,
new burning appliances will give off a paper
burning smell and orange flames will be
present. Simply open the windows for a
few hours to vent the odor.
C. Flame Appearance
Flames from the pilot and burner should be visually
checked as soon as the heater is installed. In addition,
periodically check the flames visually during operation.
Check the Pilot Flame (refer to lighting instructions)
The pilot flame must always be present when the heater is
in operation. It should just touch the top of the thermocouple
tip for natural. Refer to Figure 5.2 for correct pilot flame.
If the pilot flame does not touch the thermocouple, then the
main burner cannot function reliably. Figure 5.3 for incorrect
shape of pilot flame.

Operating Insructions
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.
