location.
! WARNING
DO NOT light or smoke cigarettes or other smoking materials while installing the EFV-TSO.
DO NOT use matches, candles or any open flame to leak test gas connections.
DO NOT use Teflon® tape or pipe sealant on any flare ends, as doing so will not provide a leak-free seal. Keep flare
end of fitting free of grease, oil and thread sealant.
DO NOT use pipe wrenches for this installation. Pipe wrenches may damage or crack gas fittings. Use only an open
ended wrench on the flat surfaces of the fittings.
NEVER loosen a connection after tightening – this may cause a leak. It is always better to tighten more if a leak is
detected. If fitting is installed improperly, remove fitting, reapply sealant and reinstall properly per instructions.
! WARNING
• STOP installation. Turn OFF the gas at the shut-off valve.
• CALL LICENSED PLUMBER to test for leaks and fix any problems.
• Do NOT use electrical equipment such as a fan to dissipate gas vapors. Electric motors will spark and can
ignite gas vapors, causing fire or explosion.
• LP gases are heavier than air and dissipate slower than natural or manufactured gases. LP gas, if released into
the home, may accumulate in low-lying areas such as basements or crawl spaces.
