SECTION A: SAFETY TIPS BE SURE TO FOLLOW THE FOLLOWING INSTRUCTIONS. The instructions which are contained in this manual are classified into the following two types, which are "WARNING" and "CAUTION". These instructions are intended to provide important information for safe operation. - Page 3 OTHER PRECAUTIONS This unit is only for indoor use. Avoid its exposure to rain or moisture. Do not use for drinking or cooking until the water supply has been approved by local authorities. Hot water (or cold water) left in heat exchanger or piping for long period of time must not used for cook- ing or drinking.

SAFETY FEATURES Ignition Safety Device (Flame Sensor) The unit will automatically stop all operations if ignition fails or if the flame fails during combustion. ''WARNING'' lamp will light. High Limit Thermistor In order to prevent burns, the high limit thermistor automatically stops all operations if the water in the heat exchanger reaches abnormally high temperatures due to temperature controller malfunction. -

SECTION C: FUEL GUIDE The OM-128HH is designed for use with ASTM D3699 1-K Kerosene, ASTM D396 Low Sulfur No.1 or No. 2 Fuel Oil, or ASTM D975 Ultra Low Sulfur Diesel (ULSD) only. Use of low-quality oil will cause burner perfor- mance to drop, leading to abnormal combustion and reduced the unit life. -
Page 9: Section D
SECTION D: OPERATION FUELING WARNING: Use ASTM D3699 1-K Kerosene, ASTM D396 Low Sulfur No.1 or No. 2 Fuel Oil, or ASTM D975 Ultra Low Sulfur Diesel (ULSD) only. Never use gasoline, thinner, benzene, light oil or waste oil, or any other high volatile liquids. CAUTION: Make sure that the fuel is clean and free from dirt and water. -
