WARNINGS
• Improper installation, adjustment, alteration,
service or maintenance can cause injury or
property damage. For assistance or additional
information, consult a qualified installer, service
agency or your gas supplier.
• Operation of this appliance when not connected
to a properly installed and maintained venting
system can result in carbon monoxide (CO)
poisoning and possible death.
• Carbon monoxide poisoning – Early signs of
carbon monoxide poisoning resemble the flu
with headaches, dizziness, or nausea. If you
have these signs, get fresh air at once! Have
the heater inspected by a qualified service
technician. Some people are more affected by
carbon monoxide than others. These include
pregnant women, people with heart or lung
disease or anemia, those under the influence
of alcohol and those at high altitudes.

Flame Color and Behavior

Your Ravelle™ 42 gas fireplace is designed for maximum heating ef-
ficiency. Therefore, upon lighting of the main burner the flames will be
semi-transparent or "bluish." After 10-20 minutes of operation the logs
will heat up and the flames will become a yellow/orange color.
Adjusting the fireplace to cause the flames to turn orange sooner may
result in poor combustion, sooting and a hazardous situation. See Figure
45 showing proper flame appearance.
When testing for proper operation - If an optional thermostat is installed
adjust it to its highest temperature setting. Visually determine that main
burner gas is burning properly: i.e., no floating, lifting or flashback.
Adjust the primary air shutter(s) as required. Check for proper main
burner operation at both high and low flame.
