TYPICAL INSTALLATION
MIXING VALVE USAGE
This appliance has been design certified as complying with Am erican N ational Standard/CS A Standard for water heat ers and is considered suitable for:
Water (Potable) Heating: All models are “considered suitable for water (potable) heating.”
Water (Potable) Heating and Space Heating: Certain models are “considered suitable for water (potable) heating and space heating.” Refer to the model and rating plate of the water heater.
FIGURE 2.
HOT 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 infirm or physically/ mentally handicapped. If anyone using hot water in your home fits 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 satisfies your hot water needs, a means such as a *Mixing Valve shall 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 Qualified 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, see Figures 109 and 110.

LOCATING THE NEW WATER HEATER
FACTS TO CONSIDER ABOUT THE LOCA TION
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. The location selected should be indoors, as close as practical to the outside wall through which the water heater vent is going to be installed, and as centralized with the water piping system as possible. The water heater, as all water heaters, will eventually leak. Do not install without adequate drainage provisions where water flow will cause damage.
2. Selected location must provide adequate clearances for servicing and proper operation of the water heater.
Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow will not cause damage to the structure. For this reason, it is not advisable to install the water heater in an attic or upper floor. 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 inches (5.1 cm) greater that the water heater dimensions and must be piped to an adequate drain. Drain pan depth must allow for access to the outer doors for servicing the pilot and burner.
INSTALLA TIONS IN AREAS WHERE FLAMMABLE LIQUIDS (VAPORS) ARE LIKELY TO BE PRESENT OR STORED (GARAGES, STORAGE AND UTILITY AREAS, ETC.): Flammable liquids (such as gasoline, solvent s, propane [LP or butane, etc.] and other substances such as adhesives, etc.) emit flammable vapors which can be ignited by a gas water heater’s pilot light or main burner. The resulting flashback and fire can cause death or serious burns to anyone in the area, as well as property damage. If installation in such areas is your only option, then the installation must be accomplished in a way that the pilot flame and main burner flame are elevated from the floor at least 18 inches (45.7 cm). While this may reduce the chances of flammable vapors, from a floor spill being ignited, gasoline and other flammable substances should never be stored or used in the same room or area containing a gas water heater or other open flame or spark producing appliance. NOTE: Flammable vapors may be drawn by air currents from other areas of the structure to the appliance.
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.
• 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 .
7
Also, the water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle.
This water heater must not be installed directly on carpeting. Carpeting mu st be protected by metal or wood panel beneath the appliance extending beyond the full width and depth of the appliance by at least 3 inches (7.62 cm) in any direction, or if the appliance is installed in an alcove or closet, the entire floor must be co ve r ed by the panel. Failure to heed this warning may result in a fire hazard.
Minimum clearances between the water heater and combustible and noncombustible construction are 0 inch at the sides, 0 inches from back, 4”(10.2 cm) from front of jacket to closet door and 3”(7 .6 cm ) from top of jacket to combustible and noncombustible material. Minimum vent clearance: 0 inches.
No vent damper , whether it is operated thermally or otherwise, is to be installed on this direct vent water heater. Alteration of any p art of the factory-furnished vent assembly could result in improper operation due to restriction of flue gases and may cause carbon monoxide poisoning.
Venting Clearances
When determining the installation location for a direct vent water heater , snow accumulation and drifting should be considered in areas where applicable. See Figures 4 through 8 and items below.
• 18” minimum in all directions from any obstruction that may interfere.
• 18” minimum from the ground and 12 “ from ceiling overhangs.
• The direct vent terminal shall terminate at least 3 feet above any forced air inlet located within 10 feet. See Figure 5.
• 9” minimum horizontally from or above any door, window or gravity air inlet into the building (50,000 BtuH input or less.)
FIGURE 3.
NOTE: Provide 24 inches (61 cm) front clearance for servicing and
a adequate clearance between the jacket top and ceiling for servicing the flue area.
Combustion Air and Ventilation
• 12” minimum horizontally from or above any door, window or gravity air inlet into the building (over 50,000 BtuH input).
• 12” minimum below any door, window or gravity air inlet into the building (50,000 BtuH input or less).
• 18” minimum below any door, window or gravity air inlet into the building (over 50,000 BtuH input).
• 18” minimum from other gravity or natural appliance outlet vents when directly above or 135° to either side of center line. See Figure 6.
• 36” minimum from any outlet vents when directly below or 45° to either side of center line. See Figure 7.
• 36” minimum in all directions from any other forced air appliance outlet vent. See Figure 7.
• The location selection must provide clearances for servicing and proper operation of the water heater. See Figure 8.
• Vent termination must not be within 4 feet of any items such as gas meters, gas valves or other gas regulating equipment.
Unless specified at time of ordering, a standard extension
kit (No. 9000687) is individually packaged and shipped with the water heater.
FIGURE 4.

FIGURE 5.
Some local codes may require a vent cap cover. Figure 9 shows the optional wire vent cap protector available from the water heater manufacturer.
A wire mesh chain link fence (see Figure 9) may be used instead of the factory cover. Care should be t aken to maintain adequate ventilation around the vent cap. If a chain link fence is installed, it must not be used as a storage area for items that may block proper ventilation.
FIGURE 9.
Flue Extensions
There are three optional extension kits available. Any combination of the three kits can be chosen; however, only one kit can be used vertically and/or horizontally, see Figures 10 & 11.
Unless otherwise specified at the time of ordering, a standard exten­sion kit (9000687) is individually packaged and shipped within the water heater carton.
FIGURE 10.
FIGURE 8.
Optional Wire Grill
When the water heater vent cap is low enough to be touched accidentally , or is accessible to small children, installation of a protective vent cover is recommended. See Figure 9.

Cutting The Opening Through The Outside Wall
After thoroughly reading the “Locating the New Water Heater” section of this manual and you have chosen a suitable water heater installation site, use Chart #1 to determine dimensions for the wall opening.
Cut a 6 1/4” (159 mm) diameter hole completely through the outside wall.
The opening through the wall should be cut at this time. If this has not been done, refer to “Cutting The Opening Through The Outside Wall ” section.
1. Lock the elbow to the straight 3” (76 mm) flue pipe. Set this assembly in place on the end of the water heater’s flue collar.
FIGURE 14.
Water Heater Attitude
There is a certain amount of variance with regard to the direction the water heater faces.
Standing in front of the water heater (gas control facing you), set the 3” (76 mm) diameter elbow (slotted end) on the flue. This will give you a better understanding of the relation of the vent assembly to the opening in the wall and more importantly any possibility of interference of venting and water piping.
The direction of the water heater can now be made. Also consider the gas control valve to insure installation, lighting and maintenance accessibility are retained.
NOTE: Supplementary installation instructions are applicable only if this direct vent water heater is provided with the alternate brown porcelain-enameled vent cap and the 6” (152 mm) vent wall assembly show below, See pages 22 thru 24.
FIGURE 15.
2. Mark the flue collar at the slots in the elbow . Using a #22 drill bit, drill holes into the flue collar at the two slots and secure the elbow to the flue collar using the screws provided.
NOTE: Make sure elbow is properly aligned to opening in the outside wall.

2. Set the vertical 3” (76 mm) diameter telescoping flue section in place on the flue collar. Using a # 22 drill bit, drill two holes (180° apart) and secure the vertical assembly to the flue collar.
FIGURE 33.
*Each part is stamped with a part number.
The opening through the wall should be cut at this time. If this has not been done, refer to “Cutting The Opening Through The Out side Wall,” on page 1 1.
1. First it must be determined how far the vertical 3” (76 mm) diameter telescoping flue sections are set and locked together using the two screws supplied.
FIGURE 31 .
Use chart #3, drawing and simple equation below, to find the length of expansion of the telescoping flue sections. Because of manufacturing tolerances, place the telescoping extension on the water heater and adjust the height (“X” Dimension) and mark the point. Once the length has been determined, lock the two sections together by drilling two holes (180° apart) in the pipe and securing with the screws supplied.
3. Slide the 6” (152 mm) vent telescoping section apart to reveal the beads. Using the caulking supplied, fill the beads.
FIGURE34.
4. Apply an ample amount of sealant around the oval flare of the jacket.
FIGURE 35.
5. Place the 6” (152 mm) vent section over the 3” (76 mm) flue section. Subtract 3/4” (19 mm) from the predetermined “X” dimension. This determines the length of the 6” (152 mm) vent extension. Slide the 6” (152 mm) vent extension apart to this dimension and secure with the two screws supplied.
