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.
Replace with new batteries.
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 grill 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-clockwise direction.
Reassemble the heater and replace the batteries.
TEST IGNITION
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.
CORRECT FLAME
Proper combustion
IMPORTANT NOTE : NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING.
Always make sure to turn the heater off and inspect it to insure that it is completely
extinguished prior to going to bed.
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.
