temperature setting. Water temperatures above 125°F can cause severe burns or death from
scalding. The thermostat is adjusted to its lowest temperature position when shipped from the
factory. Be sure to read and follow the warnings outlined on the label pictured below.
The chart shown above may be used as a guide in
determining the proper water temperature for your

Relief Valve
• The pressure rating of the relief valve must not exceed
150 psi, the maximum working pressure of the water
heater as marked on the rating plate.
• The BTUH rating of the relief valve must equal or exceed
the BTUH input of the water heater as marked on its
rating plate.
• No valve of any type should be installed between the
relief valve and the water heater.
• Discharge from the relief valve should be piped to a
suitable drain to eliminate potential water damage. Piping
used should be of a type approved for the distribution of
hot water.
• Hot and cold water lines should be insulated up to the
water heater.
• The discharge line must be NO SMALLER than the outlet
of the valve and must pitch downward to allow complete
drainage (by gravity) of the relief valve and discharge line.
• The end of the discharge line should not be threaded or
concealed and should be protected from freezing. No
valve of any type, restriction or reducer coupling should
be installed in discharge line.
NOTICE: Local codes govern the installation of relief valves. If local codes require that a temperature
and pressure relief valve should be installed the manufacturer recommends a type 40XL Watts T&P
relief valve or an equivalent model be used.

operation of the relief valve. You should take precaution to avoid contact with the hot water coming
out of the relief valve and to prevent water damage.
NOTICE: If the relief valve on the system discharges periodically, this may be due to thermal expansion
in a closed water supply system. Contact the water supplier or local plumbing inspector on how to
correct this situation. Do not plug the relief valve.

Flue Terminal Location
The location of the vent terminal depends on the following minimum clearances and considerations
(see illustration):
• Twelve (12) inches above grade level and above normal snow levels.
• Four (4) feet below, or four (4) feet horizontally from any door,
ZLQGRZVR඼WXQGHUHDYHYHQWRUJUDYLW\DLULQOHWWRWKHEXLOGLQJ
or other appliances, or from gas or electric meters. Do not locate
vent above walkways, doors, windows, air inlets, gas or electric
meters or other equipment.
• Ten (10) feet from any forced air inlet to the building. Any fresh or
make-up air inlet such as for a dryer or furnace area
is considered to be a forced air inlet.
• Eighteen (18) inches from an inside corner formed by two exterior walls.
• DO NOT install vent terminal under any patio/deck or too close

nuisance or hazard and may cause property damage. Condensate
vapor could cause damage and be detrimental to the operation of
regulators, relief valves, or other equipment.
• To help prevent moisture from freezing on walls and under eaves,
do not locate vent terminal on the side of a building
with prevailing winter winds. The water heater must be located as
close as practicable to a chimney or gas vent.
• Caulk all cracks, seams and joints within six (6) feet of vent terminal.
• All painted surfaces should be primed to lessen the chance of
physical damage. Painted surfaces will require maintenance.
• Use of cellular core PVC (ASTM F891), cellular core CPVC, or
Radel (polyphenylsulfone) in non-metallic venting systems is

Insulation blankets, available to the
general public, for external use on
gas water heaters are not
necessary. The purpose of an
insulation blanket is to reduce the
standby heat loss encountered with
storage tank heaters. This water
heater does not store water making
an insulation blanket unnecessary.
The manufacturer’s warranty does
not cover any damage or defect
caused by installation, attachment
or use of any type of energy saving
or other unapproved devices
(other than those authorized by
the manufacturer) into, onto or in
conjunction with the water heater.
The use of unauthorized energy
saving devices may shorten the
life of the water heater and may
endanger life and property.
The manufacturer disclaims any
