GSW Safety Systems

Flammable Vapour Ignition Resistant

(FVIR) technology you can trust.

GSW Water Heating has developed three unique Flammable Vapour
Ignition Resistant (FVIR) Safety Systems that reduce the risk of
accidental fires caused by the ignition of flammable vapours from
products such as gasoline, paint thinner and solvents: the Flame

®

Guard

and Flame SafeTMSafety Systems and the Superflue

Safety System.

Flame Guard®Safety System

The Flame Guard®Safety System is a recognized and proven
technology, exclusive to GSW and John Wood residential gas

water heaters. The award-winning Flame Guard
System protects the consumer by trapping burning vapours within the
water heater combustion chamber through the patented “Flame-Trap.”
As long as the vapours are present and within the flammability range,
they will continue to burn safely until they “burn themselves out.”

The Flammable Vapour Ignition Resistant (FVIR) Superflue®Safety
System is a cutting-edge design unique to GSW power vented
residential gas water heaters. The Superflue
flammable vapour sensor that protects the consumer by detecting the
presence of flammable vapours in the atmosphere around the water
heater and disabling the unit to minimize the risk of ignition. It also
features a robust air intake snorkel that inhibits flammable vapours
from entering the combustion chamber and igniting.
