Recommended Periodic Maintenance
As a state-of-the-art furnace, your heater requires periodic inspection and service by an authorized technician
to insure optimum, trouble free performance. This inspection should include: a combustion check; flue pipe
check; burner assembly check; cleaning all necessary parts and replacing gaskets as needed. Please ask
your authorized Toyostove dealer for details and scheduling. When using
Ultra Low Sulfur Diesel (ULSD)
or
Ultra Low Sulfur Heating Oil the heater should be serviced at least every two years because the distillation of
ULSHO
is heavier than 1-K Kerosene and No. 1 Fuel Oil. When using 1-K Kerosene or Low Sulfur No. 1 Fuel
Oil your heater can be serviced less frequently.
AUTOMATIC IGNITER CLEANING SYSTEM
When the heater is on and clock is set (see “set Clock” on page 9), it will automatically stop and clean the igniter
every day at 2:00 AM and will display “CL” on the digital indicator. After the cleaning mode is finished the heater will
automatically re-ignite and continue to burn again.
The igniter cleaning mode helps prolong the igniter life.
MANUAL IGNITER CLEANING SYSTEM
Heater will clean igniter for ten (10) minutes manually.
1. When ON/OFF switch is “OFF”, press the “SET” button and “CLEAR” button at the same time for more than
three (3) seconds.
2. Display will appear “CL:10” on Digital Indicator. Cleaning will begin and end without any additional input.
Note: Cleaning igniter is important to prolong igniter life. It is recommended that the igniter be cleaned once a
month if the time is not set.
