Turn the fuel valve of the fireplace, usually located beneath the steel plate adjacent to the unit, in the counter-clockwise direction until it stops turning. If the gas supply is there, the flame should ignite when the igniter is pushed. If not, it indicates that the igniter is dysfunctional. In such a case, get the igniter replaced by a licensed professional. If there is no fuel supply, replace fuel in the tank.

To check if the pilot has blown out, open the fireplace's vent, and check for a burning flame. If there is no flame, light the pilot light again using a lighter or a matchstick. The fireplace cannot ignite if the pilot light is dysfunctional. In such a case, have the pilot light replaced by a licensed professional.

If the main burner does not or is slow to turn on, tighten any loose connections, and clean the burner. To check for inadequate voltage, check the amount of energy the generator is providing. Adjust the voltage to ensure proper functioning of the main burner. In addition, tighten the thermocouple in the fireplace's gas valve.

To check if the fireplace's remote is functioning properly, replace its batteries with new ones. If the device's sensor records a temperature of above 140 degrees Fahrenheit, position the sensor at a safe distance from the unit. Check the output cables using a multi-meter, and replace any damaged cables.
