The temperature may be adjusted from 80°F/27°C to 180°F/82°C.
The thermostat was adjusted to 120°F/49°C before the heater
was shipped from the factory. It is recommended that lower water
temperatures be used to avoid the risk of scalding. It is further
recommended, in all cases, that the water temperature be set for the
lowest temperature which satises your hot water needs. This will
also provide the most energy efcient operation of the water heater
and minimize scale formation.
WATER TEMPERATURE SETPOINT ADJUSTMENT
PROCEDURE
CAUTION
THE TEMPERATURE OF THE WATER AT THE TANK OUTLET
MAY NOT CORRESPOND TO THE TEMPERATURE SETPOINT
PROGRAMMED IN THE CONTROLLER. THE USER CAN EASILY
CHANGE THE TEMPERATURE SETPOINT AT ANY TIME BY USING
THE FOLLOWING PROCEDURE. IN ALL CASES, INPUT POWER
MUST BE APPLIED TO THE CONTROLLER TO PERFORM ANY
PROGRAMMING OPERATIONS.
The Operating Set Point of this water heater determines the regulated
temperature for the water in the tank. This parameter is adjusted in the
Temperature menu. Items in this menu allow you to monitor different
temperature readings in the tank along with adjusting the Operating
Set Point and Differential. To change the current programmed
temperature setpoint value, see OPERATION section for details.
Figure 1 shows the approximate time-to-burn relationship for normal
adult skin. Short repeated heating cycles caused by small hot water
uses can cause temperatures at the point of use to exceed the
thermostat setting by up to 20°F (11C°). If you experience this type
of use, you should consider using lower temperature settings to
reduce scald hazards.
Valv es for reducing poi nt-of-us e temper ature by mi xing col d
and hot water are available (see Figure 2). Also avai lable
are inexpen siv e de vices that attach to faucets to limit hot
wate r temperatures. Conta ct a licensed plumber or t he local
plum bing aut hority.
FIGURE 2.
HIGH LIMIT SWITCH (E.C.O.)
The top immersion well of the dual bulb controller also contains
the high limit (energy cutoff) sensor. The high limit switch interrupts
the main burner gas ow should the water temperature reach
approximately 202°F/94°C. Should the high limit switch activate,
the water temperature must drop below 140°F/60°C before the
controller can be reset. The following is a possible reason for high
limit switch operation.
Temperature Time to Produce 2nd & 3rd
Setting Degree Burns on Adult Skin
180°F / 82°C Nearly instantaneous
170°F / 77°C Nearly instantaneous
160°F / 71°C About 1/2 second
150°F / 66°C About 1-1/2 seconds
140°F / 60°C Less than 5 seconds
130°F / 54°C About 30 seconds
120°F / 49°C More than 5 minutes
FIGURE 1.
• A malfunction in the thermostatic controls would allow the gas
valve to remain open causing water temperature to exceed the
thermostat setting. The water temperature would continue to
rise until high limit switch operation.
Contact your dealer or servicer if continued high limit switch
operation occurs.
DISHWASHING MACHINE REQUIREMENT
All dishwas hin g ma chines meeti ng the Nation al Sanitation
Foundation requirements are designed to operate with water
flow pressures between 15 and 25 pounds per square inch
(103 Kpa and 173 Kpa). Flow pressures above 25 pounds per
square inch (173 Kpa), or below 15 pounds per square inch
(103 Kpa), will result in improperly sanitized dishes. Where
pressures are high, a water pressure reducing or flow regulating
control valve should be used in the 180°F (82°C) line to the
dishwashing machine, and should be adjusted to deliver water
between these limits.
The Na t i on al Sani t a tion Fo u n da tion al s o re c o mmen d s
circ ulation of 180°F (82°C) water. Where this is done, the
circ ulation should be very gentle s o that it d oes not cause
an y unnece ssar y tur bulence insi de the wat er he ater . The
circ ulation should be just enough to provide 180°F (82° C)
wate r at the point of take-of f to the dishwashi ng mac hine.
Adju st fl ow by means of the plug cock in t he ci rculatin g lin e.
(See install ation di agrams.)

CIRCULATING PUMP
A circulating pump is used when a system requires a circulating
loop or there is a storage tank used in conjunction with the heater.
Refer to the piping diagrams at rear of manual for electrical hookup
information and install in accordance with the current edition of the
National Electrical Code, NFPA 70 or the Canadian Electrical Code,
CSA C22.1.
All bronze circulators are recommended for used with commercial
water heaters.
Although circulators are oiled and operated by the manufacturer
some circulators must be oiled again before operated. Please refer
to manufacturer's instructions.
INSTALLATION INSTRUCTIONS
REQUIRED ABILITY
IN S TALLAT ION OR SE RVIC E OF THI S WATER HEATE R
REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED
TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR
SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL WORK
ARE REQUIRED.
INSULATION BLANKETS
Insulation blankets available to the general public for external use
on gas water heaters are not approved for use on your water heater.
The purpose of an insulation blanket is to reduce the standby heat
loss encountered with storage tank water heaters. Your water
heater meets or exceeds the ASHRAE/IES 90.1-1999 standards
with respect to insulation and standby loss requirements, making
an insulation blanket unnecessary.
WARNING
Should you choose to apply an insulation blanket to this heater, you
should follow these instructions. Failure to follow these instructions
can result in re, asphyxiation, serious personal injury or death.
• Do not apply insulation to the top, or the upper 15" (38 cm) of the
water heater, as this will interfere with safe operation.
• Do not cover the temperature & pressure relief valve.
• Do not cover the instruction manual. Keep it on the side of the
water heater or nearby for future reference.
THE HEATER SHALL BE LOCATED OR PROTECTED SO IT IS NOT
SUBJECT TO PHYSICAL DAMAGE BY A MOVING VEHICLE.
DO NOT LOCATE THE HEATER WHERE NOISE FROM THE
EX HAUS T OR INTAK E WIL L BE OBJ ECTI ONAB LE. THIS
IN C LUDES LOCATI O NS CLO S E TO OR AC ROSS FR O M
WINDOWS AND DOORS. AVOID ANCHORING THE VENT AND
INTAKE PIPES DIRECTLY TO FRAMED WALLS, FLOORS OF
CEILINGS UNLESS RUBBER ISOLATION PIPE HANGERS
ARE USED. THIS PREVENTS ANY VIBRATIONS FROM BEING
TRANSMITTED INTO THE LIVING SPACES.
WARNING
FLAMMABLE ITEMS, PRESSURIZED CONTAINERS OR ANY
OTHER POTENTIAL FIRE HAZARD OUS A RTICLES MUST
NEVER BE PLACED ON OR ADJACENT TO THE HEATER. OPEN
CONTAINERS OF FLAMMABLE MATERIAL SHOULD NOT BE
STORED OR USED IN THE SAME ROOM WITH THE HEATER.
When installing the heater, consideration must be given to
proper location. Location selected should be as close to the
intake and exhaust termination poin ts as practicable, with
adequate air supply and as centralized with the piping system
as possible.
THE HEATER MUST NOT BE LOCATED IN AN AREA WHERE IT
WILL BE SUBJECT TO FREEZING.
LOCATE IT NEAR A FLOOR DRAIN. THE HEATER SHOULD
BE LOCATED IN AN AREA WHERE LEAKAGE FROM THE
HEATER OR CONNECTIONS WILL NOT RESULT IN DAMAGE
TO THE ADJACENT AREA OR TO LOWER FLOORS OF THE
STRUCTURE.
When such locations cannot be avoided, it is recommended that
a suitable drain pan, adequately drained, be installed under the
appliance.
WARNING
THIS WATER HEATER IS A CONDENSING UNIT AND REQUIRES
A DRAIN TO BE LOCATED IN CLOSE PROXIMITY TO ALLOW
THE CONDENSATE TO DRAIN SAFELY. THE CONDENSATE
DRAINS FROM THE UNIT AT THE EXHAUST ELBOW LOCATED
AT THE BOTTOM OF THE UNIT. NOTE: IT IS IMPORTANT THAT
THE CONDENSATE HOSE NOT BE ELEVATED ABOVE THE
EXHAUST ELBOW (SEE FIGURE 3). THE CONDENSATE BUILDUP WILL BLOCK THE EXHAUST OUTLET, WHICH WILL CAUSE

These heaters are approved for installation on combustible ooring
in an alcove when the minimum clearances from any combustion
construction are followed as indicated in Figure 4.
In all installations the minimum combustible clearances from any
vent piping shall be 0". Vent piping passing through a combustible
wall or ceiling must be a continuous run (no joints).
A service clearance of 24" (61 cm) should be maintained from
serviceable parts such as relief valves, thermostats, cleanout
openings, drain valves and venting connections.
Always disconnect electrical power before servicing the unit.
*ILLUSTRATION OF MINIMUM COMBUSTIBLE CLEARANCES
IN AN ALCOVE.
Where an exhaust fan is installed in the same room with a heater,
sufcient openings for air must be provided in the walls. UNDERSIZED
OPENINGS WILL CAUSE AIR TO BE DRAWN INTO THE ROOM
THROUGH THE HEATER’S VENTING SYSTEM, CAUSING POOR
COMBUSTION. SOOTING MAY RESULT IN SERIOUS DAMAGE
TO THE HEATER AND RISK OF FIRE OR EXPLOSION. IT CAN
ALSO CREATE A RISK OF ASPHYXIATION.
UNCONFINED SPACE
In buildings of conventional frame, brick or stone construction,
unconned spaces may provide adequate air for combustion and
ventilation.
If the unconned space is within a building of tight construction
(buildings using the following construction: weather stripping,
heavy insulation, caulking, vapor barrier, etc.), air for combustion
and ventilation must be obtained from outdoors. The installation
instructions for conned spaces in tightly constructed buildings must
be followed to ensure adequate air supply.
CONFINED SPACE
When drawing comb ustion air from ins ide a conventionally
constructed building to a conned space, such a space shall be
provided with two permanent openings, ONE IN OR WITHIN
12 INCHES (31 cm) OF THE ENCLOSURE TOP AND ONE IN OR
WITHIN 12 INCHES (31 cm) OF THE ENCLOSURE BOTTOM. Each
opening shall have a free area of at least one square inch per 1000
Btuh (2,203mm2/kW) appliances in the enclosure, but not less than
100 square inches (645 cm²).
FIGURE 4.

WARNING
NEVER OPERATE THE HEATER UNLESS IT IS VENTED TO THE
OUTDOORS AND HAS ADEQUATE AIR SUPPLY TO AVOID RISKS OF
IMPROPER OPERATION, FIRE, EXPLOSION OR ASPHYXIATION.
VENT PIPE TERMINATION
NOTE: Before installing venting, determine place of vent pipe
termination. See Figure 5 and 6 before proceeding.
CAUTION
DO NOT TERMINATE THE VENTING WHERE NOISE FROM THE
EXHAUST OR INTAKE WILL BE OBJECTIONABLE. THIS INCLUDES
LOCATIONS CLOSE TO OR ACROSS FROM WINDOWS AND DOORS.
AVOID ANCHORING THE VENT AND INTAKE PIPES DIRECTLY TO
FRAMED WALLS, FLOORS OR CEILINGS UNLESS RUBBER ISOLATION
PIPE HANGERS ARE USED. THIS PREVENTS ANY VIBRATIONS FROM
BEING TRANSMITTED INTO THE LIVING SPACES.
IMPORTANT
The vent system must terminate so that proper clearances are
maintained as cited in local codes or the current editions of the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas
and Propane Installation Code, CAN/CSA-B149.1.
WARNING
WH EN THE U NIT IS TO BE SETUP AS A DI RECT VENT,
TH E INTAKE GUAR D AND THE BALA NCE PLATE MUST
BE REMOVED. TH E INLE T VE N T PI P E MAY THEN BE
GL UED TO THE AI R INTAK E (see Figure 8) PRO VIDED
ON TH E UN IT.
Do not terminate the exhaust vent terminal over public area where
condensate or vapor can cause nuisance or hazard.
Plan the vent system layout so that proper clearances are maintained
from plumbing and wiring.
Vent pipes serving power vented appliances are classied by building
codes as "vent connectors". Required clearances from combustible
materials must be provided in accordance with information in this
manual under LOCATION OF HEATER and CLEARANCES, and
with National Fuel Gas Code and local Codes.
IMPORTANT
Plan the layout of the vent system backwards from the vent
termination to the appliance.
WARNING
USE ONLY THE VENT TERMINALS SUPPLIED WITH THIS UNIT.
TERMINATION OF A VENT SYSTEM WITH A DEVICE OTHER THAN
THE SUPPLIED VENT TERMINATIONS WILL AFFECT SYSTEM
PERFORMANCE AND RESULT IN A SAFETY HAZARD.
DIRECT VENTING
The air intake provided on the unit contains an intake guard, see

IMPORTANT
WHEN LOCATING THE TERMINALS ON A SIDEWALL, THE
FOLLOWING SPECIFICATIONS PERTAINING TO TERMINAL
LOCATION MUST BE FOLLOWED.
FIGURE 7.
1. The intake vent terminal and the exhaust vent terminal must
terminate on the same exterior wall and must be located at
a minimum of 24" (61cm) from the vertical centerline of the
exhaust vent terminal (see Figure 9). In colder climates
increasing the 24" (61cm) minimum to 48" (122cm) will
reduce possibility of frost over from side winds blowing
exhaust vapors to the air intake of the direct the vent and is
recommended for Canada.

2. The horizontal centerline of the intake vent terminal may not be
located lower than the horizontal centerline of the exhaust vent
terminal (see Figure 9).
FIGURE 9.
INSTALLATION SEQUENCE
For installations in the City of Los Angeles, California Category IV
PVC Pipe such as that manufactured by Brownline Pipe Company,
must be used as vent pipe material.
CAUTION
Vent terminals supplied with the heater must be used.
Slide the pipe through the wall and insert into coupling on the
other side of the wall, making sure that the vent terminal ends
up pointed in the correct position. See Figure 10.
EXHAUST VENT TERMINAL
NOTE: BEFORE BEGINNING INSTALLATION OF ANY VENT
PIPE READ THE VENT PIPE MANUFACTURER'S INSTALLATION
INSTRUCTIONS.
1. After the points of termination have been determined, use the
cover plates as templates to mark the holes for the vent pipes
to be inserted through the wall. BEWARE OF CONCEALED
WIRING AND PIPING INSIDE OF WALL.
2. If the vent terminals are being installed on the outside of a nished
wall, it may be easier to mark both the inside and outside wall.
Align the holes by drilling a hole through the center of the template
from the inside through to the outside. The template can now be
positioned on the outside wall using the drilled holes as a centering
point for the template.
3. A) MASONRY SIDE WALLS
Chisel an opening approximately 1/2" (1.3 cm) larger than the
marked circle.
B) WOODEN SIDE WALLS
Drill a pilot hole approximately one quarter inch outside of the
marked circle. This pilot hole is used as a starting point for a
saws-all or sabre saw blade. Cut around the marked circle staying
approximately one quarter inch outside of the line. (This will allow
the vent pipe to easily slide through the opening. The resulting
gap will be covered by the vent terminal cover plates.) Repeat
this step on the inside wall if necessary.
4. Cut a length of PVC pipe about 3.5" (8.9 cm) longer than the wall
thickness at the opening.
5. Glue the intake vent terminal to the section of the pipe.
6. Slide the wall plate over the pipe to stop against intake vent terminal.
7. Place a bead of caulking (not supplied) around the gap between
the pipe and the wall. Place some of the caulking on the back of
the plate to hold it against the wall after installation.
8. If the vent pipe is installed up to the wall, with a coupling on the
end against the wall opening, the pipe with the vent terminal
can be prepared for gluing before inserting through the wall.

VERTICAL VENT TERMINAL INSTALLATION
IMPORTANT
WHEN TERMINATING THROUGH A ROOF, THE FOLLOWING
SPECIFICATIONS PERTAINING TO TERMINAL LOCATION MUST
BE FOLLOWED.
1. Proper support must be provided for all pipe protruding through
the roof.
2. The vertical roof terminations should be sealed with a plumbing
roof boot or equivalent ashing.
3. The intake vent termination and the exhaust vent termination
must penetrate the same side of roof.
4. The center line of the intake vent termination and the center
line of the exhaust vent termination must be no closer than
24" (61cm).
5. The intake vent terminal and the exhaust vent terminal must be
oriented facing downward and the same direction.
The specications are displayed in Figure 11.
NOTE: Exhaust vent terminal is installed using the same procedure.
