Page 8: Typical Installation
This appliance has been design certified 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. TYPICAL INSTALLATION MIXING VALVE USAGE FIGURE 2. -
Page 9: Locating The New Water Heater
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. -
Page 10: Insulation Blankets
in an alcove or closet, the entire floor must be covered by the panel. Failure to heed this warning may result in a fire hazard. Minimum clearances between the water heater and combustible construction are 0 inch at the sides and rear, 5.5" (14.0 cm) from the front and 12"... - Page 11 area of one square inch per 1000 Btu/hr (22 cm all appliances in the enclosure, but not less than 100 square inches (645 If the confined space is within a building of tight construction, air for combustion and ventilation must be obtained from outdoors. When directly communicating with the outdoors or communicating through vertical ducts, two permanent openings, located in the above manner, shall be provided.

Page 12: Installing The Water Heater
INSTALLING THE NEW WATER HEATER CHEMICAL VAPOR CORROSION CORROSION OF THE FLUEWAYS AND VENT SYSTEM MAY OCCUR IF AIR FOR COMBUSTION CONTAINS CERTAIN CHEMICAL VAPORS. SUCH CORROSION MAY RESULT IN FAILURE AND RISK OF ASPHYXIATION. Spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride (water softener salt), waxes, and process chemicals are typical compounds which are potentially corrosive. -
Page 13: Temperature-Pressure Relief Valve
Figure 10 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 3/4 inch NPT water connections. NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the water heater connections. Do not solder the water lines directly to the water heater connections. -
Page 14: Gas Piping
GAS PIPING Make sure the gas supplied is the same type listed on the model rating plate. The inlet gas pressure must not exceed 14 inch water column (3.5 kPa) for natural and propane gas (L.P.). The minimum inlet gas pressure shown on the rating plate is that which will permit firing at rated input. -
Page 15: Sediment Traps
SEDIMENT TRAPS A sediment trap shall be installed as close to the inlet of the water heater as practical at the time of water heater installation. The sediment trap shall be either a tee fitting with a capped nipple in the bottom outlet or other device recognized as an effective sediment trap. -
Page 16: Vent Pipe Termination
WARNING VENT HOOD(S) MAY BE EXTREMELY HOT DURING OPERATION. VENT PIPE TERMINATION The first step is to determine where the vent pipe will terminate. See Figures 15, 20 and 21. The vent may terminate through a sidewall as shown in Figure 20 or through the roof as shown in Figure 21. The vent system must terminate so that proper clearances are maintained as cited in local codes or the current edition of the National Fuel Gas Code, (ANSI Z223.1, 12.9.1 through 12.9.4) or the Natural... -
Page 17: Planning The Vent System
PLANNING THE VENT SYSTEM Plan the route of the vent system from the discharge of the blower to the planned location of the vent terminal. 1. Layout total vent system to use a minimum of vent pipe and elbows. 2. This water heater is capable of venting flue gases equivalent to 25' (7.6 m) of 2"... -
Page 18: Condensate
The condensate trap may be primed by filling the CONDENSATE U- ASSEMBLY with tap water using the supplied hose while the water heater is not operating. The system is fully primed when the hose is lowered below the hose clamp on the side of the water heater and water begins to flow out of the hose. - Page 19 2. If the Vent Terminal is being installed on the outside of a finished 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.

INSTALLATION OF VENT SYSTEM, SIDEWALL With the route of the venting system and selection of materials completed, as discussed in the section of this manual titled PLANNING THE VENT SYSTEM, the through the wall vent terminal in place and the first section of piping, up to first elbow, installed at the blower it is time to complete the installation of the venting system for the sidewall installation. -
Page 21: Vent Attenuation Assembly Installation Instructions
VENT ATTENUATION ASSEMBLY INSTALLATION INSTRUCTIONS The Vent Attenuation Assembly (VAA) is designed to provide a reduction in fan noise created in the blower wheel. This installation of this VAA is optional. Review directions thoroughly prior to installing the new VAA. Please contact the manufacturer of the water heater as shown in the instruction manual with any questions or for additional product support. - Page 22 8. Take the end of the tube at the bottom of the floor and route it to a suitable drain. This will provide an area where the condensate can drain without affecting the area around the appliance. 9. Once installed along with the rest of the vent configuration, make sure to operate the unit through at least one heat up cycle to ensure there is no leakage around the hose barb or any joints of the VAA or vent pipe system.

Page 23: Vent Pipe Preparation
VENT PIPE PREPARATION 1. INITIAL PREPARATION Make sure the solvent cement you are planning to use is designed for the specific application you are attempting. Know the physical and chemical characteristics and limitations of the PVC and CPVC piping materials that you are about to use. Know the reputation of your manufacturer and their products. - Page 24 B. Deburring Use a knife, plastic pipe deburring tool, or file to remove burrs from the end of small diameter pipe. Be sure to remove all burrs from around the inside as well as the outside of the pipe. A slight chamfer (bevel) of about 10°-15°...

FOR YOUR SAFETY READ BEFORE OPERATING WARNING: explosion may result causing property damage, personal injury or loss of life. BEFORE OPERATING: ENTIRE SYSTEM MUST BE FILLED WITH WATER AND AIR PURGED FROM ALL LINES. A. This appliance does not have a pilot. It is equipped with an ignition device which automatically lights the burner. -
Page 26: Temperature Regulation
TEMPERATURE REGULATION 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 satisfies your hot water needs. This will also provide the most energy efficient operation of the water heater. -
Page 27: For Your Information
START UP CONDITIONS SMOKE/ODOR It is not uncommon to experience a small amount of smoke and odor during the initial start-up. This is due to burning off of oil from metal parts, and will disappear in a short while. THERMAL EXPANSION 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,... -
Page 28: Periodic Maintenance
PERIODIC MAINTENANCE VENTING SYSTEM INSPECTION At least once a year a visual inspection should be made of the venting system. You should look for: 1. Obstructions which could cause improper venting. The combustion and ventilation air flow must not be obstructed. 2. -
Page 29: Anode Rod Inspection
INSTALLED IN SUITABLE AREA: To insure sufficient ventilation and combustion air supply, proper clearances from the water heater must be maintained. See “Locating the New Water Heater” section. Combustible materials such as clothing, cleaning materials, or flammable liquids, etc. must not be placed against or adjacent to the water heater which can cause a fire. -
Page 30: Service
SERVICE If a condition persists or you are uncertain about the operation of the water heater contact a service agency. Use this guide to check a “Leaking” water heater. Many suspected “Leakers” are not leaking tanks. Often the source of the water can be found and corrected. -
