Check for gas leaks

Determine if water treatment is needed

ODORANTROR ANYNUNUSUALSODORO $O not proceed with start-up if there is any indication of a gas leak. Repair any leak at once.

0ROPANEABOILERSSONLY 9OUR PRO- pane supplier mixes an odorant with the propane to make its presence detectable. In some instances, the odorant can fade and the gas may no longer have an odor.

s0ROPANEP GASA CANA ACCUMULATE at floor level. Smell near the floor for the gas odorant or any unusual odor. If you suspect a leak, do not attempt to light the pilot.
