OPERATION - RDV33/40 TCC Models Only
Blower Speed Control
This appliance is equipped with a hot air circulating blower. The speed
of the blower is controlled by the Remote. The blower speed can be
adjusted through six (6) speeds.
To activate this function use the Mode Key to index to the blower control
icon (see Figures 23 and 24). Use the Up/Down Arrow keys to turn on,
off or adjust the blower speed. A single "beep" will confirm reception
of the command.
Note: The blower can be controlled only by the remote. Turning the
appliance off with the unit mounted three position slider switch (Figure
22) will NOT turn off the blower. To turn off the blower, use the remote
in lieu of or prior to shutting the appliance off at the three position slider
switch (Figure 22).
Blower speed will be indicated by either an Off, Level Bar, or HI shown
in the Set Point/Temp/Level/State indicator area.
Key Lock
This function will lock the keys to avoid unsupervised operation. To
activate this function, press the MODE and UP keys at the same time.
To de-activate this function, press MODE and UP Keys at the same time.
Manual Bypass Of The Remote System
If the batteries of the Receiver or Remote are low or depleted, the appli-
ance can be turned on manually by sliding the three position slider switch
to the ON position. This will bypass the remote control feature of the
system and the appliance main burner will come on.
OPERATION - ALL MODELS

Flame Color and Behavior

This appliance is designed for maximum heating efficiency. 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 appliance to cause the flames to turn orange sooner may
result in poor combustion, sooting and a hazardous situation. See Figure
27 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.

Paint Curing

This appliance has been painted with a high temperature metallic stove
paint. It leaves the factory dry to the touch, but finishes curing as the
appliance is used. Fire the appliance four successive times for ten minutes
each time with a five minute cool down between each firing. Ventilate the
house during these first firings as the paint gives off an unpleasant odor.
It is recommended that persons sensitive to an imbalance in the indoor
air quality avoid the appliance during the curing process.

Quiet Operation

As the appliance 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 rush-
ing air may be heard. The blower sounds may be reduced by adjusting
the speed of the blower assembly. Also, a slight clicking sound may be
heard as the gas valve or blower switch turn on and off.

Blower Operation

This appliance comes equipped with a 150 CFM blower with a variable
speed control and an automatic temperature activated On/Off snap switch.
Operation:
1. Plug the power cord into a grounded (three-prong) outlet. This appliance
is equipped with a three-prong (grounding) plug for your protection
against shock hazard and should be plugged directly into a properly
grounded three-prong receptacle. Do not cut or remove the grounding
prong from this plug.
2. After the appliance warms up, the blower will turn on if the speed control
(located in the control compartment or on the remote control) is left
in the "ON" position. The blower will not operate until the appliance
is warm.
3. Once the blower turns on, turn the knob (IPI) or adjust the remote
control (TCC) to the desired speed. No further adjustment is neces-
sary.
4. If you do not wish to have the blower on, turn the knob until it clicks
to the "OFF" position or turn the remote control to the "OFF" position.
