Model SBF-300 Circulator
INSTALLATION AND OPERATING INSTRUCTIONS
NOTE: The SBF-300 Circulators are approved for use with all of the following
gas log sets: HM2 SERIES
11-1903 1/2019
Page 2
INSTALLATION:
1. Gas supply must be turned “OFF” before installing the SBF-Series Circulator.
2. If the gas log set has been installed before the circulator is installed, the logs must be removed from the grate.
3. The SBF-Series Circulator is adjusted by removing three screws and sliding down to the other holes and reinserting the three screws. This should only be done if the fireplace is shorter than the Circulator. Install the
circulator in the fireplace with the discharge duct facing the room. If the burner unit is already
installed, tilt the circulator forward so that the legs are perpendicular to the floor. After the circulator legs are
behind the burner unit, rotate the circulator to its normal position (See Figure 1).
Note: When properly installed, the circulator should be 1/8” from the rear of the grate and in the center of the
burner unit. If the leg assembly will not slide underneath the grate assembly due to the regulator, slide the
circulator slightly to one side and complete the installation.
4. This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazard and
must be grounded in accordance with the National Electrical Code, ANSI/NFPA No. 70-1991.
5. Route the electric cord on the bottom of the fireplace. Do not route the cord under the circulator.
6. Position logs on the burner unit as described in the gas log instruction manual that was packaged with your log
set.

NOTE: If any of the original wire that was supplied with the appliance, needs to be replaced, it must be
replaced with type SPT2 or its equivalent.
OPERATION:
NOTE: There may be some initial smoke and/or odor from the blower during the first hours of operation.
1. Plug the circulator cord into a 110 volt outlet.
2. The circulator is equipped with a built-in thermostat that will cause the fan to operate with the burner
unit operating. The burner unit may need to operate approximately (5) minutes before the fan thermostat
allows the fan to turn on. After the burner shuts off, the fan may continue to run for approximately (5)
minutes before the fan thermostat allows it to shut off. The fan is designed to automatically operate with
the burner unit as long as the electrical cord is plugged in.
3. If glass doors are installed on the fireplace, the doors must be opened completely while the unit is operating.
WARNING: Do not operate gas logs while the circulator is off. This can cause damage to
the circulator.
