Thermal Ring
Auto Shut-Off
In the case of a gas line rupture or a disconnect from the appliance, the Eastman ARMOR BOOST™ thermal excess flow valve will
immediately shut-off the supply of gas. The flow of gas is controlled only at the appliance where the problem exists. The valve will
remain in the closed position until the gas line has been properly repaired.

BOOST YOUR PEACE OF MIND.
Eastman has designed a safety valve to help protect you and
your family from catastrophic ruptures or disconnects in your
gas line. The
ArmorBoost valve immediately restricts gas flow to help
protect you from build-up of flammable gas. The valve will
remain activated until the gas line is properly repaired. For
added protection, ArmorBoost is armed with a special fire safe
thermal ring that expands to stop gas flow when extreme
temperatures of 350˚+ are reached.
High Performance DuraCoat™ Epoxy Coating provides extra
protection from corrosion, chemical stains from common
household products, UV rays and is approved for indoor/out-
door use.
