DANGER: Failure to install the draft hood on indoor
installations and properly vent the heater to the

manual can result in unsafe operation of the heater.
To avoid the risk of fire, explosion, or asphyxiation
from carbon monoxide, never operate this heater

supply for proper operation. Be sure to inspect the
vent system for proper installation at initial start-up;
and at least annually thereafter. Refer to the
Maintenance section of this manual for more
information regarding vent system inspections.

will operate is the same type as that specified on the
heater rating plate.
DANGER: When servicing or replacing components
that are in direct contact with the water, be certain
that:
• There is no pressure in the heater. (Pull the release
on the relief valve. Do not depend on the pressure
gauge reading).
• The heater water is not hot.
• The electrical power is off.

WARNING: Both natural gas and propane have an
odorant added to aid in detecting a gas leak. Some
people may not physically be able to smell or
recognize this odorant. If you are unsure or
unfamiliar with the smell of natural gas or propane,
ask your local gas supplier. Other conditions, such
as "odorant fade," which causes the odorant to
diminish in intensity, can also hide, camouflage, or
otherwise make detecting a gas leak by smell more
difficult.
WARNING: UL recognized fuel gas detectors are
recommended in all enclosed propane and natural
gas applications wherein there is a potential for an
explosive mixture of fuel gas to accumulate and their
installation should be in accordance with the
detector manufacturer's recommendations and/or
local laws, rules, regulations, or customs.
