IMPORTANT SAFETY INFORMATION
DANGER
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 the air supply piping properly 
installed and terminated to the outdoors. 
•   Be sure to inspect the vent terminal, the air intake, 
and the 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 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 property 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 
Schedule 40 PVC (foam core is not permitted at any 
time), Schedule 80 PVC, CPVC, ABS, UL 1738-listed 
Category III Stainless Steel, or InnoFlue® PP. No other 
vent material is permitted. For Canada, installations 
must follow ULC S636 for exhaust venting.
• 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 may 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. See page 39 for 
information on venting and clearances to multiple 
terminations. 
CAUTIONS:
•   Ensure that the appliance vent is securely glued and 
attached to the vent connection on the top of the water 
heater. DO NOT USE SCREWS.
•   DO NOT operate without the condensate drain connected 
and routed to a proper drain.
