Flame Appearance / Air Shutter Adjustment

The GF 400 DV Sebago gas stove is shipped from the factory equipped to burn Natural gas with the air shutter set at the halfway position. Please be aware, however, that this initial setting may not provide the optimal flame picture in your particular installation. No single setting will be appropriate for all vent configurations, fuel types, or installation environments. The air shutter setting can also be adjusted to achieve the desired flame appearance. Flame appearance is a matter of individual preference, however, most people enjoy a warm yellowish flame.

Too much air - the appliance will generate a flame that is blue and transparent, or an “anemic” flame.

Too little air - the appliance may generate very long yellow flames resulting in soot. Sooting produces black deposits on the logs, on the inside walls of the appliance, and potentially, on the exterior termination cap. Sooting is caused by incomplete combustion and lack of combus- tion air entering the air shutter opening.

To adjust the air shutter: CAUTION! USE WORKGLOVES. SURFACES MAY BE HOT!

1.Reach under the right side of the stove and loosen the wingnut located closest to you. See fig. 29. Slide the wingnut stem forward to open the air shutter and increase air. Slide the shutter stem back to decrease the air supply.

2.Tighten the wingnut to secure the shutter at the desired setting.

3.Operate the burner for 30 minutes on the HIGH setting, observing the flame continuously. If the flame appears weak, slow, or sooty, adjust the air shutter to a more open position as described above until the flame is as desired. Make adjustments in small increments and allow the burner to settle in before making further adjustment

WARNING: AIR SHUTTER ADJUSTMENTS SHOULD ONLY BE PERFORMED BY A QUALIFIED PROFESSIONAL SERVICE TECHNICIAN.

Optional Wall Thermostat or Remote Control

Use only a 750 millivolt DC two-wire circuit thermostat with this appliance. The thermostat should be placed in the same room as the heater, typically 5 feet off the floor. Avoid drafty areas or any area that may affect the accuracy of the thermostat.

The thermostat should be connected to the GF 400 DV Sebago using a minimum of 16 gauge wire with a maximum length of 25 feet of wire.

Connect the two thermostat wire leads to the two lower terminals on the terminal block located directly above the ignitor button. Do not overtighten the connections. IT IS NOT NECESSARY TO DISCONNECT ANY OTHER WIRES. See Fig. 30.

For thermostatic operation, the On/Off/T-Stat switch on the back of the stove must be in the T-stat position, and the pilot light must be running, as it is the power source for the thermostat.

At the thermostat, the two wires should be con- nected to the two connection screws on the thermostat base plate per the manufacturer’s instructions.

Remote Control

When using a remote, the remote receiver should be wired to the terminal block the same way the thermo- stat would be. See the instructions above.

Follow the operating instructions included with the Remote Control unit.

CAUTION:

LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING THE CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER OR DANGEROUS OPERATION. ALWAYS VERIFY PROPER OPERA- TION AFTER SERVICING THE APPLIANCE.
