This appliance has been design certifi ed as complying with
American National Standard/CSA Standard for water heaters
and is considered suitable for:
Water (Potable) Heating and Space Heating: All models are
considered suitable for water (potable) heating and space heating.
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated
to a temperature which will satisfy space heating, clothes washing, dish washing, and other sanitizing needs can scald and
permanently injure you upon contact. Some people are more
likely to be permanently injured by hot water than others. These
include the elderly, children, the infi rm, or physically/mentally
handicapped. If anyone using hot water in your home fi ts into
one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you
must take special precautions. In addition to using the lowest
possible temperature setting that satisfi es your hot water needs,
a means such as a *Mixing Valve, should be used at the hot
water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores.
Consult a Qualifi ed Installer or Service Agency. Follow mixing
valve manufacturer’s instructions for installation of the valves.
Before changing the factory setting on the thermostat, read the
“Temperature Regulation” section in this manual.

LOCATING THE NEW WATER HEATER
FACTS TO CONSIDER ABOUT THE LOCATION
Carefully choose an indoor location for the new water heater,
because the placement is a very important consideration for the
safety of the occupants in the building and for the most economical use of the appliance. This water heater is not for use in
manufactured (mobile) homes or outdoor installation.
Whether replacing an old water heater or putting the water heater
in a new location, the following critical points must be observed:
1. Select a location indoors as close as practical to the vent
terminal or location to which the water heater vent piping is
going to be connected, and as centralized with the water piping system as possible.
2. Selected location must provide adequate clearances for servicing and proper operation of the water heater.
• Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain
pan.
• Water supply shut-off devices that activate based on the water pressure differential between the cold water and hot water
pipes connected to the water heater.
• Devices that will turn off the gas supply to a gas water heater
while at the same time shutting off its water supply.
Also, the water heater must be located and/or protected so it is
not subject to physical damage by a moving vehicle.
Installation of the water heater must be accomplished in such a
manner that if the tank or any connections should leak, the fl ow
will not cause damage to the structure. For this reason, it is not
advisable to install the water heater in an attic or upper fl oor.
When such locations cannot be avoided, a suitable drain pan
should be installed under the water heater. Drain pans are available at your local hardware store. Such a drain pan must have
a minimum length and width of at least 2 in. (51mm) greater that
the water heater dimensions and must be piped to an adequate
drain. The pan must not restrict combustion air fl ow.
Water heater life depends upon water quality, water pressure
and the environment in which the water heater is installed. Water
heaters are sometimes installed in locations where leakage may
result in property damage, even with the use of a drain pan piped
to a drain. However, unanticipated damage can be reduced or
prevented by a leak detector or water shut-off device used in
conjunction with a piped drain pan. These devices are available
from some plumbing supply wholesalers and retailers, and detect and react to leakage in various ways:
• Sensors mounted in the drain pan that trigger an alarm or
turn off the incoming water to the water heater when leakage
is detected.
This water heater must not be installed directly on carpeting.
Carpeting must be protected by metal or wood panel beneath
the appliance extending beyond the full width and depth of the
appliance by at least 3 in. (76mm) in any direction, or if the appliance is installed in an alcove or closet, the entire fl oor must be
covered by the panel. Failure to heed this warning may result
in a fi re hazard.
8
INSULATION BLANKETS
Insulation blankets available to the general public for external use
on gas water heaters are not necessary with this product. 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 National Appliance Energy Conservation Act standards with respect to insulation and standby loss
requirements, making an insulation blanket unnecessary.
Confi ned Space is a space whose volume is less than 50 cubic
feet per 1,000 Btu per hour (4.8 cm per kW) of the aggregate
input rating of all appliances installed in that space.
VENT TERMINATION
Before installing water heater determine placement of vent termination.
Make certain to observe vent location limitation, see Figures 3,
4 & 11.
Minimum clearances between the water heater
and combustible and noncombustible construction are: 0 in.
(0mm) from sides, 0 in. (0mm) from back, 4 in. (102mm) from
front of jacket to closet door and 20 in. (508mm) from top of
jacket to combustible and noncombustible material. Minimum
vent clearance: 1 in. (25mm)*. Provide 3 ft. (915mm) front clearance for servicing and adequate clearance between the jacket
top & ceiling for servicing the fl ue area, see Figure 4.
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions (See Figure 1 for identifi ca-
tion of components mentioned below). Failure to follow these
instructions can restrict the air fl ow required for proper combus-
tion, resulting in fi re, asphyxiation, serious personal injury or
death.
• Do not cover the outer door, thermostat or temperature &
pressure relief valve.
• Do not cover the instruction manual. Keep it on the side of
the water heater or nearby for future reference.
• Do obtain new warning and instruction labels from the manufacturer for placement on the blanket directly over the existing labels.
* Where the wall is combustible and the wall thickness is over
14 in. (356mm), 1 in. (25mm) clearance to combustible materials
around the vent terminal is needed. The fi rst 14 in. (356mm) is
zero clearance.
Make certain the vent locations comply with the National Fuel
Gas Code ANSI Z223.1/NFPA 54 and/or local codes. There is
some important information shown in Figure 11.
For a second or more direct vent unit, the distance between vent
terminals must be a minimum of 12 in. (305mm).

INSTALLING THE NEW WATER HEATER
REQUIRED ABILITY
INSTALLATION OR SERVICE OF THIS WATER HEATER
REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED
TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR
SUPPLY, VENTING AND GAS SUPPLY ARE REQUIRED.
INSPECT SHIPMENT
There may be hidden damage caused in transit. Check to
be certain all parts of the venting system, as listed below,
are present. CAUTION!!! IF THERE ARE ANY DAMAGED
PARTS, DO NOT INSTALL THIS WATER HEATER. REPORT
ANY SHORTAGE TO YOUR DISTRIBUTOR OR DAMAGE TO
YOUR CARRIER.
GENERAL
The installation must conform to these instructions and the local code authority having jurisdiction. In the absence of local
codes, the installation must comply with the current editions of
the National Fuel Gas Code ANSI Z223.1/NFPA 54. The code is
available from the Canadian Standards Association, 8501 East
Pleasant Valley Road, Cleveland, OH 44131.
WATER PIPING
This water heater shall not be connected to any heating systems
or component(s) used with a non-potable water heating appliance.
All piping components connected to this unit for space heating
applications shall be suitable for use with potable water.
Toxic chemicals, such as those used for boiler treatment shall
not be introduced into this system.
When the system requires water for space heating at temperatures higher than required for domestic water purposes, a
tempering valve must be installed. Please refer to Figure 2 for
suggested piping arrangement.
Water supply systems may, because of such events as high line
pressure, frequent cut-offs, the effects of water hammer among
others, have installed devices such as pressure reducing valves,
check valves, back fl ow preventers, etc. to control these types of
problems. When these devices are not equipped with an internal
by-pass, and no other measures are taken, the devices cause
the water system to be closed. As water is heated, it expands
(thermal expansion) and closed systems do not allow for the
expansion of heated water.
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated
to a temperature which will satisfy space heating, clothes washing, dish washing, cleaning and other sanitizing needs can scald
and permanently injure you upon contact. Some people are
more likely to be permanently injured by hot water than others.
These include the elderly, children, the infi rm, or physically/men-
tally handicapped. If anyone using hot water in your home fi ts
into one of these groups or if there is a local code or state law
requiring a certain temperature water at the hot water tap, then
you must take special precautions. In addition to using the lowest possible temperature setting that satisfi es your hot water
needs, a means such as a *mixing valve, should be used at the
hot water taps used by these people or at the water heater, see
Figure 2. Valves for reducing point of use temperature by mixing
cold and hot water are also available:
Consult a Qualifi ed Installer or Service Agency. Follow man-
ufacturer’s instructions for installation of the valves. Before
changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual.
The water within the water heater tank expands as it is heated
and increases the pressure of the water system. If the relieving
point of the water heater’s temperature-pressure relief valve
is reached, the valve will relieve the excess pressure. The
temperature-pressure relief valve is not intended for the
constant relief of thermal expansion. This is an unacceptable
condition and must be corrected.
It is recommended that any devices installed which could create
a closed system have a by-pass and/or the system have an expansion tank to relieve the pressure built by thermal expansion
in the water system. Expansion tanks are available for ordering
through a local plumbing contractor. Contact the local water
supplier and/or a service agency for assistance in controlling
these situations.
NOTE: To protect against untimely corrosion of hot and cold
water fi ttings, it is strongly recommended that di-electric
unions or couplings be installed on this water heater when
connected to copper pipe.
All gas piping must comply with local codes and ordinances or
with the National Fuel Gas Code ANSI Z223.1/NFPA 54 whichever applies. Copper and brass tubing and fi ttings (except tin
lined copper tubing) shall not be used.
