Subject: FVIR Warning Label ECO # 6849
Please be advised that Engineering has recently released to Manufacturing a
change to the Warning Label on our FVIR approved models. The new label states
"Water heaters in Residential garages must be installed and located, or
protected, to avoid physical damage". The new label no longer references the
need for an 18 -inch water heater stand in a Garage Installation in
accordance with section 8.1.10.1 of the latest edition of the National Fuel Gas
Code (ANSI Z223.1 -1).
The new FVIR Warning label is currently being installed on all FVIR approved
water heaters shipping from the factory. Attached is a copy of the new warning
label along with the page from the National Fuel Gas Code referencing this
change. I also attached the page from our current Residential Gas (FVIR models)
installation and operation manual referencing Residential Garage Installations.
Please let me know if you have any questions

100 Chapter 8 • Equipment Installation
Areas of buildings in which flammable liquids are openly used, handled, or dispensed include
any area•where non -water -based paints and varnish are used. Automotive painting facilities
probably would be best served by the use of direct -vent equipment or an indirect steam or
hot water coil in a makeup air unit with a remote boiler to ensure that the boiler is not in
the proximity of the flammable vapors that are generated by the painting process.
0 Liquids that readily generate flammable vapors include gasoline, mineral spirits, acetone,
denatured alcohol, oil -based paint and lacquer thinners, and camp stove fuel. For information
on safe, recommended storage enclosures for these materials, see NFPA 30, Flammable and
Combustible Liquids Code,
Installers must verify that the room in which an appliance is being installed is not an
area where flammable vapors will be present routinely. Although the future uses (or misuses)
of a room cannot be predicted, gasoline, paint thinners, and other household solvents '
be verified as not being stored and used in the room. A small spill of gasoline or other
flammable liquid will create an invisible vapor cloud near the floor, because the vapors
generated usually are heavier than air. This cloud can be drawn into an appliance through
its combustion air intake, ignite, and flash back to the liquid pool. Many water heaters come
0 with warning labels that describe this hazard to the installer and consumer.
Residential gas water heaters designed to resist the ignition of flammable vapors are
D likely to become available in the near future (see commentary following paragraph 8.1.10).
These new water heaters, listed to ANSI Z21.10.1, Gas Water Heaters — Volume I— Storage,
Water Heaters with Input Ratings of 75,000 Btu per Hour or Less, will be required to meet
a flammable vapor ignition test as part of their listing. Their installation requirement under
C 11• subsection 8.1.9 is different from the installation requirement for. residential garages under
subsection 8.1.10. Whereas paragraph 8.1.10.1 mandates that all gas utilization equipment
1 installed in residential garages be installed so that their burners and burner ignition devices
are at least 18 in. (460 mm) above the floor, subsection 8.1.9 requires that gas appliances
not be installed in areas where flammable vapors are likely to be present (except for residential
garages) "unless the design, operation, and installation are such to eliminate the probable
ignition of flammable vapors." Residential water heaters listed to the revised ANSI Z21.10.1
standard (which contains the flammable vapor ignition test) should not be installed in these '
c_ locations. The intent of the standard's flammable resist requirements is to provide protection
from accidental spills in residential locations. The current flammable resist water heater
design renders the water heater unusable after activation and would require that the entire
water heater be replaced. Commercial locations where routine handling of flammable liquids
`� occurs due to business activities are an entirely different hazard class not addressed by the
ANSI appliance standard. .
` 8.1.10 Installation in Residential Garages.
!: 8.1.10.1 Gas utilization equipment in residential garages and in adjacent spaces that open
to the garage and are not part of the living space of a dwelling unit shall be installed so that
all burners and burner ignition devices are located not less than 18 in. (460 mm) above the
floor unless listed as flammable vapor ignition resistant.
4 The possibility of flammable liquids being spilled in reside ntial garages where gas appliances
are installed is addressed in paragraph 8.1.10.1. Much concern has been voiced over the past
several years regarding the ignition of flammable vapors by gas appliances, specifically
residential water heaters. The standard for water heaters, ANSI Z21.10.1, Gas Water Heaters
— Volume I — Storage, Water Heaters with Input Ratings of 75,000 Btu per Hour or Less,
was revised by the ANSI Z21 committee in May 1999. Changes to the standard require that
all residential water heaters pass a flammable vapor ignition resistance test in order to be
listed. There has been a delay in listing of water heaters to the new requirements because
of questions on the testing procedure, which have been resolved. At the time of publication,
