Air Shutter Adjustment
The Ravelle™ 42 gas fireplace has an air shutter control lever located
at the upper left corner beneath the firebox (see Figure 46). The lever
is linked to the primary air shutter on the main burner. The air shutter
regulates the amount of primary air the burner receives and therefore
how clean the fireplace burns. The air shutter should only be adjusted by
a qualified gas technician. The fireplace should burn for about 15 minutes
with the logs installed before adjusting the air shutter. Moving the lever
to the left will open the shutter and turn the flames more transparent
and blue. Moving the lever to the right will close the shutter and turn the
flames more orange.
CAUTION: The air shutter should never be set so as to make the tips of
the flames sooty or create sooting on the viewing glass, logs, or heat
exchanger. If soot begins to form after burning, the air shutter should
be opened gradually until the sooting condition stops. Gas quality and
gas pressure may vary which can affect the burning characteristics of
the fireplace.
Figure 46Quiet Operation
As the Ravelle 42 gas fireplace is burning a number of normal operational
sounds may be heard. The flow of gas through the gas valve and orifice
may make a rushing or whistling noise. If this noise is objectionable,
it can be reduced by turning down the flame. Turning down the flame
can reduce total heat output by more than 30%. When the blower turns
on, the sound of rushing air may be heard. The blower sounds may be
reduced by adjusting the speed control located behind the lower door.
Also, a slight clicking sound may be heard as the gas valve or blower
switch turn on and off.
Blower Operation
Your Ravelle 42 gas fireplace comes equipped with a 200 CFM blower
with a variable speed control and an automatic temperature activated
on/off snap switch.
Operation:
1. After the fireplace warms up, a heat activated switch will turn on the
fan. A fan speed control is located behind the lower door. The speed
control has an off position and the knob can be rotated to set the fan
at the desired speed. The fan will not operate until the fireplace is
warm.
2. Once the fan turns on, set the speed control knob to the desired
speed. No further adjustment is necessar y, the fan will turn on and
off automatically whenever the fireplace is warm.
3. If you do not wish to have the fan on, turn the speed control knob
until it clicks to the “OFF” position.
Optional Wall Thermostat
If an optional wall thermostat is to be installed, install the thermostat per
the manufacturers instructions (provided with the thermostat). Failure
to follow manufacturers instructions could result in a malfunction. Pay
special attention to the thermostat location requirements. If the loca-
tion requirements are not adhered to the appliance, erratic operation or
failure may occur.
Do not mount the thermostat where it may be affected by:
• Radiant heat from this appliance, fireplaces, sun or other heat
sources.
• Drafts or dead spots behind doors or in corners.
• Hot or cold air from ducts.
Paint Curing
This fireplace has been painted with a high temperature metallic paint. It
leaves the factory dry to the touch, but completes the curing process as
the fireplace is used. To cure the paint, burn the appliance four successive
times for 10 minutes each time with a five minute cool down between
each firing. Also some parts of the appliance may be lightly coated with
machining oil. Ventilate the house during these first firings as the paint
and oil give off unpleasant odors. It is recommended that persons sensi-
tive to an imbalance in the indoor air quality avoid the fireplace during
the curing process.
