1-24 SAFETY MECHANISMS
Several safety mechanisms have been built into the
Laser Heating System. These devices protect the user
against personal injury, protect the heater against
damage, shut down the heater and display an error code
on the digital indicator if a malfunction occurs.
1-25 POWER FAILURE RECOVERY
SYSTEM
When an electric power failure occurs while the heater is
in operation, the heater will automatically re-start and
run in "NORMAL" mode after the power is restored.
1-26 CLOTH COVERED EXHAUST PIPE
Insulating cloth covers are to be placed over all metal
surfaces of the exhaust line during installation. Since
combustion by-products are vented at elevated
temperatures, the exhaust pipe will become hot during
operation. The insulating cloth covers protect the user from
accidental contact burn with these heated metal surfaces.
IMPORTANT:
Do not operate the heater without
the insulating covers. During
installation make sure that all
exhaust lines are tightly connected.
1-27 AIR CIRCULATION FAN COVER
This fan cover is an integral part of the fan assembly
and protects the user against physical injury which could
occur from accidental contact with the revolving metal
fan blade.
1-28 FUSE
In the event of a power surge or an internal wiring
hazard, the fuses will open and power to the heater will
be cut off. The fuses are rated at 125 V AC, 10-amps
and 125 V AC, 3-amps.
The electrical outlet into which the heater connected
should be protected by at least a 15-amp. fuse or circuit
breaker.

Overheat protector switch is rated at 195°F (90°C).
Should a heater overheat (internal temperature rises
beyond 195°F (90°C)), the overheat protector switch
(also called a high limit switch) will open to shut off the
heater. Error code "EE12" will be displayed on the digital
indicator at this time. The overheat protector switch will
automatically reset after the heater has cooled down.
Once the heater has cooled to 150°F (65°C), the system
can be restarted manually as follows:
1. Press ON/OFF switch to "OFF".
2. Allow heater to cool down.
3. Resolve the cause of the overheat.
4. Press ON/OFF switch to "ON" to start.
The heater will start with normal operation.
Automatic igniter cleaning system
The heater will automatically turn to the "OFF" cycle at
2:00 AM everyday and the igniter will be on for self-
cleaning for ten (10) minutes. "CL:10" will be shown on
the digital indicator at this time.
Manual igniter cleaning system
you can clean the igniter manually for ten (10) minutes
as follows:
1. Press both the "HOUR" button and "MINUTE" button
2. "CL:10" will be shown on the digital indicator.
3. Disconnect the heater from power source during the

at the same time for more than three (3) seconds
when ON/OFF switch is "OFF".
Cleaning will begin and end without any additional
input.
IMPORTANT:
Cleaning the igniter is important to
prolong igniter life. It is recom-
mended that the igniter be cleaned
at least once a week.
