LP TANKS FROM LOCAL LP SUPPLIER MUST NOT
BE USED TO STORE ANYTHING (SUCH AS FERTIL-
IZER) EXCEPT LP GAS. THIS INCLUDES ALL DELIV-
ERY VESSELS (LP TRUCKS). IF MATERIAL OTHER
THAN LP GAS IS USED IN THE SAME
VESSELS/TANK AS THE LP GAS, THE LP GAS CAN
BECOME CONTAMINATED AND DAMAGE THE FUR-
NACE. THIS WILL VOID THE MANUFACTURER’S
WARRANTY. CONTACT THE SUPPLIER TO MAKE
SURE FERTILIZER IS NOT USED IN THE SAME
TANKS USED TO STORE AND DELIVER LP GAS.
