Jotul GF300 DV manual Flame Appearance / Air Shutter Adjustment, Remote Control

Flame Appearance / Air Shutter Adjustment

The GF 300 DV gas stove is shipped from the factory equipped to burn Natural gas. If the stove has been converted for use with propane, the Air Shutter may require adjustment to achieve the desired flame appear- ance. Other installation related variables can also affect the flame picture. The Air Shutter may be opened or closed to provide the best flame picture for your specific installation.

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

Too small an air setting - the appliance will generate very long yellow flames resulting in soot. Sooting pro- duces 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 in the flames and lack of combustion air entering the air shutter opening.

To adjust the air shutter:

1.Reach under the right side of the stove and loosen the wingnut located closest to you. See fig. 30. Slide the wingnut stud forward to open the air shutter and back to provide less air. Make adjustments in small incre- ments.

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

3.Allow the stove to burn for 30 minutes on the HIGH setting, observing the flame continuously. If the flame appears weak, slow, or sooty, repeat the process described above until the flame is as desired.

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 300 DV using a minimum of 16 gauge wire with a maxi- mum 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. 31.

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.
