NEVER LEAVE THE HEATER

UNATTENDED WHILE BURNING!

¢￿ CHECKING THE IGNITION SYSTEM

If the automatic ignition system fails to operate properly,

perform the following checks:

¡'BATTERIES -2 "C" cell batteries are located at the rear of the heater.

Igniter

Replace with new batteries.

 

Fig.15

¡'IGNITER PLUG - If the automatic ignition system still doesn't work

after replacing the batteries, check the igniter plug. If the glow coil

 

filament is broken, bent, or doesn't glow when engaged via the ignition lever, it must be replaced.

CAUTION: Be sure igniter plug is Type "B", 2.5V DC, 1A only.

To replace the igniter plug (Fig. 15);

¡'Remove the batteries.

¡'Remove the 2 cabinet screws and lift off the cabinet and grille assembly. ¡'Pull the ignition lever to raise the igniter plug.

¡'Push the igniter plug in and turn in a clockwise direction to remove.

¡'Install a new igniter plug (Type "B", 2.5V DC, 1A only) by pushing it in and turning it in a counter-clockwisedirection.

¡'Reassemble the heater and replace the batteries.

¡'TEST IGNITION ¡'Using the wick adjuster knob, raise the wick to its maximum height.

Pull the ignition lever.

The igniter plug should be within 1~2mm of the wick when the ignition lever is fully engaged.

¢￿ ADJUSTING THE WICK

After lighting the heater, it is important to check the heater flame within the first 5-7 minutes of operation. During the first 5 minutes after ignition, the burner chamber warms up and flames will become visible at the top of burner. These flames will gradually build up. After 5-7 minutes of operation, you should use the wick adjuster knob to obtain the proper flame height. The proper flame height is a flame of no more than 1/2" at the top of the burner, with an even distribution of flame around the flame spreader disk which is positioned in the center of the top portion of the burner. See pictures below for reference.

As you continue to operate the heater, the temperature of the heater and the temperature of the room will continue to change. As the heater warms up, the kerosene in the tank will vaporize faster, and this could require adjusting the wick adjuster down in order to maintain the desired 1/2" flame height. Therefore, it is necessary to continue to monitor the flame height, and to make adjustments using the wick adjuster knob to keep the proper flame height. It is recommended that the heater be checked every 30 minutes in order to keep the proper adjustment because periodic adjustment is required.
