Why?

• The CPSC (Consumer Product Safety Commission)
  looked for ways to reduce injuries and deaths
  from gas fired water heaters
• June of 1994 CPSC advised the water heater
  industry it wanted a solution to the problem
• Water Heater Joint Research and Development
  Consortium was formed

Ignition of Flammable Vapors and Gas Water
Heaters-Standard Change

• ANSI Z21.10.1 will be amended to include testing
  for flammable vapor ignition resistance and the
  accumulation for Lint, Dust and Oil.

• Design Criteria
• Gasoline Spill Test
• Lint, Dust and Oil

Flame Arrestor
6
As air enters through the ScreenLokTM Flame
Arrestor, the up to 18,000 geometrically
oriented, micro-dimensioned louvers increase the
velocity of incoming air into the combustion
chamber.
Arrestor
The combination of high velocity air entering the
chamber and the vector effect caused by
combustion will prevent any flames present in the
chamber from traveling backwards through the
arrestor plate and outside of the water heater.
7
Scrubbing the Air
During normal operation, combustion air is drawn
into the water heater through openings in the
jacket.
8
Scrubbing the Air
The combustion air enters through holes in the
very bottom of the chamber.

Keys to Safe Operation

• Seal Integrity
• There are several screws on the inner combustion
  chamber door. When working on the heater, it is
  important the gasket be intact when reinstalling
  the door and all screws are re-installed.
• If the gasket is damaged, you must replace it
  with a new one.
