National Fuel Gas Code, ANSI Z223.1-Latest Edition) and/or in Canada CAN/CGA B149 Installation Codes (Latest Editions). The warranty for this water heater is in effect only when the water heater is installed, adjusted, and operated in accordance with these Installation and Operating Instructions. -
Page 5: Installation
The National Fuel Gas Code (ANSI Z233.1-or latest edition) and CAN/CGA (B149.1-or latest edition), expressly prohibits the installation of a water heater in a garage, unless the unit is installed so that the burner and ignition devices are at least eighteen (18) inches (46 cm) above floor level and protected to avoid damage by a moving vehicle. -
Page 6: If You Smell Gas
Installation (Locating The Water Heater) continued- Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors. Examples of some typical compounds that are potentially corrosive are: spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes and process chemicals. - Page 7 When such locations cannot be avoided, a suitable drain pan adequately piped for proper drainage, must be installed under the water heater.
-
Page 8: Minimum Clearances
If the water heater is to be installed directly on carpeting, it must be installed on top of a metal or wood panel extending beyond the full width and depth of the appliance by at least three (3) inches (7.6 cm) in any direction or, if the appliance... - Page 9 Venting continued- (F) The vent system must be inspected at least once a year to ensure against leakage of exhaust products. Exceptions For Installations in Canada: (A) The vent terminals must be located at least 1 foot (.31 m) from any window or door, which can be opened in any building, any non-mechanical air supply inlet to any building, or the combustion air inlet to any other appliance.

Page 24: Water Connections
The COLD water inlet and HOT water outlet are identified on the top of the water heater. The fittings at the cold-water inlet and hot water outlet are dielectric waterway fittings with 3/4” (1.9 cm) NPT male thread. Make the proper plumbing connections between the water heater and the plumbing system to the house. - Page 25 NOT thread, plug or cap the discharge line. It is recommended that a minimum clearance of four (4) inches (10.2 cm) be provided on the side of the water heater for servicing and maintenance of the combination temperature and pressure relief valve.
- Page 26 ASSE approved mixing valve in the water system. This valve will reduce point of discharge temperature by mixing cold and hot water in branch supply lines. Such valves are available from the manufacturer of this water heater or a local plumbing supplier. Please consult with a plumbing professional.

14.0” water column (3.5 kPa) for natural gas and liquefied petroleum gases/propane gas. 1. Connect this water heater only to the type of gas (Natural or Propane gas) as shown on the rating plate. Use clean 1/2 inch (1.3 cm) black iron pipe. (Dirt and scale from the pipe can enter the combination control and cause it to malfunction). -
Page 28: Electrical Connections
If a flexible line cord and plug is permitted by local code, then provide a (3) three wire grounding type receptacle within 6 feet (1.9 m) of the water heater and use the flexible cord provided. Do not plug the line cord into a receptacle that can have the power supply interrupted by a switch that is used to turn on and off lights. - Page 29 Electrical Connections (Figure 9) continued- Figure 9...

A licensed plumbing professional or local plumbing authority should be consulted. Note: This water heater is equipped with an energy cut out device to prevent overheating. Should overheating occur, turn off the electrical supply to the water heater and contact a qualified service technician. -
Page 33: Burner Flame Check
Burner Flame Check Cast Iron Burner: At the time of installation and at periodic intervals (not more than 6 months), a visual check of the main burner and pilot flames should be made to determine if they are burning properly. For ideal operation, the gas and air must be properly proportioned. -
Page 34: Maintenance
See Burner Flame Check section on page 31. If sooting or other burner anomalies are evident, shut down the water heater by turning off the gas per the instructions listed in this manual or as listed on the water heater. - Page 35 NOTE: It is imperative for proper operation of the water heater that the inner door be replaced in the original location. When lifting lever of the combination temperature and pressure relief valve, hot water will be released under pressure.

Page 41: Vent Pipe Preparation And Joining
VENT PIPE PREPARATION AND JOINING Most failures in PVC, CPVC or ABS systems result from improper preparation and joining of pipe and fittings. The guidelines below must be followed when installing the venting system. If you have any question about the application or installation of the PVC, CPVC or ABS venting system, contact the manufacturer, supplier, or your plumbing professional. - Page 42 Vent Pipe Preparation and joining (continued)- d) Cementing must be done quickly to avoid over-drying before joining. Apply one coat to the outside end of the pipe at a width slightly greater than the depth of the socket. Apply a coat around the inside of the fitting socket. iii) Apply a second coat around the end of the pipe.
