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 Safe TM Safety 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
® Safety
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.”
Flame Safe TM Safety System Used
on John Wood ® DV Water Heaters
Flame Safe TM technology - designed to protect the consumer
against the ignition of flammable vapours.
Superflue ® Safety System Used
on John Wood ® PV Water Heaters
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
® Safety System features a
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.
