7. Plug the gray fan power cord into the receptacle located on the left end of the box.
8. Place the temperature control switch (C) (magnet attached) onto the bottom of the firebox. This control switch activates the fan as the
fireplace heats and its location determines how quickly the fan will turn ‘on’ and ‘off’ and may be adjusted as desired. When placed in
a cooler area, it will take longer for the fan to turn ‘on’, but will turn ‘off’ sooner after the burner has been turned ‘off’.
9. Turn the speed control counter-clockwise until you hear a ‘click’. This is the ‘OFF” position.
10. Turn the speed control ‘ON’ by turning the knob clockwise past the ‘click’ - this is the highest setting.
NOTE: The fan will not operate unless the speed control has been turned ‘ON’. The fan will not turn ‘ON’ until sufficient heat is
appliedtothe thermostaticcontrolswitch. Thefan will turn‘ON’and‘OFF’ automaticallywhenthefireplaceheatsandcools. Adjust
fan to desired speed while it is running.
TEMPERATURE CONTROL SWITCH POSITION: Prior to adjusting the temperature control switch, unplug the 3-prong plug on the
fan cord from the receptacle. Adjust the position of the temperature control switch to a warmer location under the firebox to turn
the fan ‘ON’ sooner or move it to a cooler location under the firebox to turn the fan ‘ON’ later. The fan will turn on when the sensor
in the temperature control switch reaches 110oF and will turn ‘OFF’ when the sensors reach 90oF. After adjustment, plug the 3-
prong plug on the fan cord into the receptacle.

IMPORTANT:
ALL CONNECTIONS WHETHER FIELD OR FACTORY MADE MUST BE CHECKED
FOR LEAKS!
NOTE: The appliance and its individual shutoff valve must be disconnected from the gas supply piping
system during any pressure testing of that system at test pressures in excess of ½ psi.
NOTE: The appliance must be isolated from the gas supply piping system by closing its individual
manual shutoff valve during any pressure testing of the gas supply piping system at test pressures
equal to or less than ½ psi.
Pressure check taps for both the manifold (outgoing) & inlet (incoming) pressures are located in front
of the gas valve. The right pressure tap is the manifold pressure and the left pressure tap is the
incoming pressure. Follow instructions on page #28 for checking these pressures.
H) MILLIVOLT BOARD REMOVAL / INSTALLATION. See Figures 12A & 12B.
NOTE: The fireplace is equipped with the millivolt board already installed. Follow these procedures
should the millivolt board need replacing or is removed for servicing.
The control valve is reversible and may be installed so it is accessible from the opposite side from
which it is factory-installed. See page #14 for instructions.
MILLIVOLT BOARD REMOVAL.
1. Shut off the gas supply at the manual
shut-off valve.
2. Disconnect gas line flex tube from the
manual shut-off valve.
3. Disconnect any wall switch, remote
control or thermostat from the valve.
4. Remove the logs from the firebox.
5. Loosen and remove the (2) 1/4" nuts
securing the burner cover. Remove the
burner cover & heat shield. Figure 12A.
6. Loosen and remove the (8) 1/4" nuts and,
