6.When oil is lit, replace the catalyst/ top burn ring and shut the door (a slightly cracked door is helpful for a short period of time to aid initial light-up of oil, but should not be required for more than 30 seconds). Until the flue pipe warms up and draft is initiated, your Oil Classic will burn with a high, yellow/orange flame. This is normal during start-up. It is simply burning off excess liquid oil that accumulates in the burner bottom before the catalyst turns red and begins to vaporize the fuel.
7.Within a few minutes, the stove burner should begin burning blue at flame base and yellow at flame tip.
8.Run the stove for at least 30 minutes on low or medium to allow the whole stove and chimney to come up to operation temperature.
9.You are now ready to adjust or “tune” your Oil Classic according to the following carburetor adjustment section.
CARBURETOR ADJUSTMENTS:
Your Oil Classic has a carburetor that has both low-fire (setting 1) and high-fire (setting
6)adjustment screws on the top. They are small slotted screws that are of red color and may need to be adjusted for correct flame size.
Both low- and high-fire settings have been pre-set at the factory, but depending on your choice of fuel (#1 or #2 grade), these will usually need to be adjusted for the viscosity of fuel you are using. Please note that after initial warm-up, it is important to adjust the high flame first, then the low flame as any adjustments made to the high can affect the low, but not vice- versa. Below is a description of what the flame should look like at both low– and high-fire:
Low-fire:
The flame should be totally blue with blue flame “spears” or jets dancing be- tween the inner wall of the burn pot and the catalyst. The catalyst will be dull red to bright red. There will be blue flame appearing around the fire ring at the burner top. You can decrease the setting to where there is only the blue spears in the burn pot and little activity of blue flame at the burner top. However, if there is any yellow flame in the burn pot on low setting, then the low-fire adjustment screw needs to be increased to a total blue flame condition. Please remem- ber that although the fuel consumption figures can be attained, there always needs to be enough BTU loss (fuel consumed that is energy loss up the pipe) in order to maintain an efficient draft. Thus a smaller, well insulated chimney is highly recommended.
High-fire:
The flame should be bright yellow with a 2/3 fire-box height to where the flame will begin to break up and terminate just a few inches under the firebrick baffle. The base of the flame at the burner ring should still be blue, and the catalyst will be a dull red. If the flame is too high and allowed to impinge on the firebrick baffle too much, the result will be a cooling of the flame tip, and incomplete combustion, thereby producing smoke and soot. Adjust the high-fire adjustment screw to achieve proper flame size.
*EACH ADJUSTMENT OF NO MORE THAN ONE-QUARTER TURN SHOULD BE ALLOWED TO STABILIZE FOR FIVE MINUTES BEFORE MAKING ANY FURTHER ADJUSTMENTS ON EITHER HIGH– OR LOW-FIRE.
*MAKE SURE THE FLUE AND STOVE IS WARMED UP BEFORE MAKING ANY CARBURETOR ADJUSTMENTS.
