FLAMMABLES
Flammable Vapors
Water heater has a main
burner flame.
The main burner flame:
1. which can come on
at any time and
2. will ignite flammable
vapors.
Vapors:
1. cannot be seen,
2. are heavier than air,
3. go a long way on the
floor and
4. can be carried from
other rooms to the
main burner flame by
air currents.
Vapors from flammable
liquids will explode and
catch fire causing death or
severe burns.
Do not use or store flammable
products such as gasoline,
solvents or adhesives in the
same room or area near the
water heater.
Keep flammable products:
1. far away from heater,
2. in approved containers,
3. tightly closed and
4. out of children's reach.
Installation:
Do not install water heater
where flammable products will
be stored or used unless the
main burner flame is at least
18" above the floor. This will
reduce, but not eliminate, the
risk of vapors being ignited
by the main burner flame.
Read and follow water heater warnings and instructions. If
owners manual is missing, contact the retailer or manufacturer.

Water Heater Venting Safety
DANGER:
Failure to install and properly vent
the water heater to the outdoors as outlined in the “Venting”
section of the Installation Instructions in this manual will
result in death from fire, explosion, or asphyxiation from
carbon monoxide. NEVER operate this water heater unless it
is properly vented and has an adequate air supply for proper
operation.
Be sure to inspect the vent terminal, the air intake, and
the coaxial vent system on the water heater for proper
installation at initial start-up and at least annually thereafter.
Refer to the “Care and Cleaning” section of this manual for
more information regarding coaxial vent system inspection.
WARNINGS:
• Gasoline and other flammable liquids, materials, and
vapors (including paint thinners, solvents, and adhesives)
are extremely dangerous. DO NOT handle, use, or store
gasoline or other flammable or combustible materials
anywhere in the vicinity of a water heater or any other
appliance. Be sure to read and follow the labels on the
water heater, as well as the warnings printed in this
manual. Failure to do so can result in death, bodily injury,
or property damage.
• Combustible construction refers to adjacent walls and
ceilings and should not be confused with combustible or
flammable products and materials. Combustible materials,
such as clothing, cleaning materials, or flammable liquids,
should never be stored in the vicinity of this or any gas
appliance. Fire or explosion can occur causing death,
personal injury, and/or product damage. See page 29 for
clearances to combustible materials.
• Follow vent manufacturer’s instructions for venting
installation, including additional clearances from
combustibles, to avoid conditions that can lead to death,
personal injury, and/or property damage.
• Use tankless water heater manufacturer-approved Category
III Stainless Steel vent material only. No other vent material
is permitted.
• Moisture in the flue gas will condense as it leaves the vent
terminal. In cold weather this condensate can freeze on the
exterior wall, under the eaves, and on surrounding objects.
Some discoloration to the exterior of the building is to be
expected. However, improper location or installation can
result in severe damage to the structure or exterior finish
of the building.
• For multiple-unit installation, a minimum distance
between vent terminations must be maintained to prevent
recirculation of vent gases. Maintain a center-to-center
distance between vent terminations of 19 in. (48 cm) for
two-unit installation. Maintain a center-to-center distance
between vent terminations of 21 in. (53 cm) for installation
of three or more units.
CAUTIONS:
• Ensure that the appliance vent is securely attached to the
water heater collar.
• Condensate must drain away from the water heater and
should not be allowed to drain back into any part of the vent
system.
•
DO NOT
operate without the condensate trap connected to
the vent and routed to the proper drain.
• Follow the vent manufacturer’s installation instructions
because the design might vary from manufacturer to
manufacturer.
