START-UP AND SHUTDOWN INSTRUCTIONS

Read the Instructions Below Before Trying to Start the

If you do not follow these instructions exactly, a fire or explo-
sion may result causing property damage, personal injury,

fuel oil. Be sure to smell next to the floor because fuel oil is heavier
than air and will settle on the base of the chamber. Look for any oil
leaks around the base of the furnace.

pump to the "on" position. Never use tools. If the valve will not
operate by hand, don't try to repair it, call a qualified service tech-
nician. Force or attempted repair may result in a fire or explosion.
