Connect fuel gas fitting on hose/regulator assembly to pro-
pane tank(s). Turn fuel gas fitting counterclockwise into threads
on tank. Tighten firmly using a wrench.

set the excess-flow check valve, close propane supply valve
and open it again slowly.
5.
Check all connections for leaks. Apply mixture of liquid soap
and water to gas joints. Bubbles forming show a leak that must
be corrected.

for leaks after installation or servicing. Never use an
open flame to check for a leak. Apply a mixture of
liquid soap and water to all joints. Bubbles forming
