DESA INTERNATIONAL

VENT-FREE NATURAL GAS STOVE HEATER

OPERATING

HEATER

Continued

In the AUTO mode, the thermostat in the hand-held remote unit con- trols the room temperature. To in- crease the room temperature, press the top arrow of the TEMP button. To lower the room temperature, press the bottom arrow of the TEMP button. At higher settings the heater will run longer.

IMPORTANT: This remote control has been specially engineered to take an air temperature sample ev- ery minute in the auto mode. It will not respond immediately to the temperature setting being turned up or down.

IMPORTANT: The hand-held re- mote control unit must be near the heater. Do not keep the hand-held remote control unit too close to the heater. The thermostat on the hand-held remote control unit will heat up too quickly and turn the heater off.

3.To turn the burner off, press the AUTO/ON/OFF button until OFF lights. The pilot will remain lit.

IMPORTANT: To turn the pilot off, manually turn the control knob on the heater to the OFF position.

LIGHTING

INSTRUCTIONS

SVYD18N and FSVYD18N Manual-Variable Control Models

NOTICE: During initial operation of new heater, burning logs will give off a paper-burning smell. Open damper or window to vent smell. This will only last a few hours.

1.STOP! Read the safety information page 14, column 1.

2.Make sure equipment shutoff valve is fully open.

3.Press in and turn control knob clock-

wise to the OFF position.

4.Wait five (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Fol- low “B” in the safety information on page 14, column 1 . If you don’t smell gas, go to the next step.

5.Slightly depress and turn control

knob counterclockwise C-clockwiseto the PILOT position. Keep control knob pressed in for five (5) seconds (see Figure 28).

Note: You may be running this heater for the first time after hook- ing up to gas supply. If so, the con- trol knob may need to be pressed in for 30 seconds or more. This will al- low air to bleed from the gas system.

6.With control knob pressed in, press and release ignitor button. This will light pilot. The pilot is attached to the burner (see Figure 18, page 11). If needed, keep pressing ignitor button until pilot lights.

Note: If pilot does not light, contact a qualified service person or gas sup- plier for repairs. Until repairs are made, light pilot with match. To light pilot with match, see Manual Light- ing Procedure, page 17.

7.Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob.

Note: If pilot goes out, repeat steps 3 through 7.

If control knob does not pop out when released, contact a qualified service person or gas supplier for repairs.

8.Slightly depress and turn control

knob counterclockwise C-clockwiseto the HIGH position. The burner should light. Set control knob to any heat level between HIGH and LO.

VARIABLE CONTROL

OPERATION

The variable control valve can be set to any heat setting and flame height desired, by simply turning the control knob until that setting is attained. Even the lowest setting provides realistic, dancing yellow flames. Selecting higher settings produces greater heat output. This results in in- creased heating comfort.

WARNING: Do not operate heater between PILOT and HIGH positions.

CAUTION: Do not try to adjust heating levels by using the equip- ment shutoff valve
