RESIDENTIAL GAS WATER HEATERS OWNER'S MANUAL Power Vented Gas Models Thank you for buying this energy efficient water heater from State Water Heaters. We appreciate your confidence in our products. PR6 40 XCVIT PR6 40 CCVIT You should thoroughly read this manual before installation and/or operation of this water heater. Please pay particular attention to the important safety and operating instructions as well as the WARNINGS and CAUTIONS.
GET TO KNOW YOUR WATER HEATER REPLACEMENT PARTS AND DELIMING PRODUCTS (A) (B) (C) (D) (E) (F) (G) Replacement parts and recommended delimer may be ordered through authorized servicers or distributors. Refer to the Yellow Pages for where to call or contact State Water Heaters, 500 Lindahl Parkway, Ashland City, TN 37015. When ordering parts, provide complete model and serial numbers (see rating plate), quantity and name of part desired (as listed in Figure 1).
then call your gas supplier or service agent. Keep area clear until a service call has been made. GENERAL SAFETY INFORMATION At times you may not be able to smell an LP gas leak. One cause is odor fade, which is a loss of the chemical odorant that gives LP gas its distinctive smell. Another cause can be your physical condition, such as having a cold or a diminishing sense of smell with age. For these reasons, the use of a propane gas detector is recommended.
AIR REQUIREMENTS INSTALLATION Dilution air temperature must be 100°F or less. In calculating the free area of a vent opening, the blocking effect of screens, louvers and grills should be considered. Screens shall not be of a mesh smaller than 1/4 inch square. If the free area is not known, the current edition of National Fuel Gas Code ANSI Z223.1/NFPA 54 recommends using figures of 20-25 percent free area for wood louvers or 60-75 percent for metal grills or louvers.
CAUTION In cold climates provide protection against freeze-up. THE HEATER SHOULD BE LOCATED IN AN AREA WHERE LEAKAGE OF THE TANK OR CONNECTIONS WILL NOT RESULT IN DAMAGE TO THE AREA ADJACENT TO THE HEATER OR TO LOWER FLOORS OF THE STRUCTURE. When such locations cannot be avoided, a suitable drain pan should be installed under the heater, see fig. 1. The pan should have a minimum length and width of at least 2 inches greater than the diameter of the heater and should be piped to an adequate drain.
To prevent damage, care must be taken not to apply too much torque when attaching gas supply pipe to gas valve inlet. The thermostat inlet has a pad for use with back up wrench. IMPORTANT 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/NFPA 54, 7.3.4e and 7.8a,b, as follows: Apply joint compounds (pipe dope) sparingly and only to the male threads of pipe joints.
WARNING VENT HOOD(S) MAY BE EXTREMELY HOT DURING OPERATION FIGURE 3 3. A) MASONRY SIDE WALLS Chisel an opening approximately one half inch 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.
d.) Splice field wiring into existing wiring using code authorized method (wire nuts, etc.). Do not plug in power cord until vent system is completely installed. The Power Vent operates on 110-120 Vac, therefore a grounded outlet must be within reach of the six (6) foot flexible power cord supplied with the unit (see fig. 1). The power cord supplied may be used only where local codes permit. If local codes do not permit the use of a flexible power supply cord: e.

C. Know the reputation of your manufacturer and their products. D. The total vent system should not exceed that which is specified in the table on page 9. Know your own qualifications or those of your contractor. The solvent welding technique of joining PVC and CPVC pipe is a specialized skill just as any other pipe fitting technique. E. All of the pipe should be secured as per the instructions in the “INSTALLATION OF VENT SYSTEM” on page 9.
RECOMMENDED BRUSH* SIZE FOR PRIMER AND CEMENT APPLICATIONS Nominal Pipe Size Brush Width (IPS) (INS.) 2 1-1/2 3 1-1/2 - 2-1/2 *USE ONLY NATURAL BRISTLE D. Inspection, cleaning, priming Visually inspect the inside of the pipe and fitting sockets and remove all dirt, grease or moisture with a clean dry rag. If wiping fails to clean the surfaces, a chemical cleaner must be used. Check for possible damage such as splits or cracks and replace if necessary.
G. Cleanup and joint movement Remove all excess cement from around the pipe and fitting with a dry cotton rag. This must be done while the cement is still soft. The joint should not be disturbed immediately after the cementing procedure, and sufficient time should be allowed for proper curing of the joint. Exact drying time is difficult to predict because it depends on variables such as temperature, humidity and cement integrity.
FOR YOUR SAFETY READ BEFORE OPERATING WARNING: If you do not follow these instructions exactly, a fire or 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. Do NOT try to light the burner by hand. B. BEFORE OPERATING smell all around the appliance area for gas.
TEMPERATURE REGULATION To avoid any unintentional changes in water temperature settings, the control has a tamper resistant feature for changing the temperature setting. To change the temperature setting follow these instructions: 1. “Wake Up” the temperature indicators by holding down both “COOLER” and “HOTTER” temperature adjustment buttons at the same time for one second (See Figure 9). One or two of the temperature indicators will light up.

VENTING SYSTEM HAVE VENTING SYSTEM CHECKED EVERY SIX MONTHS FOR OBSTRUCTIONS AND/OR DETERIORATION IN VENT PIPING. BLOWER ASSEMBLY MAINTENANCE • Turn off the gas and cold water inlet valve to the heater. • Open a nearby hot water faucet and the heater drain valve. • BE CAREFUL TO GRASP THE DRAIN VALVE HANDLE SO THAT THE HAND IS NOT EXPOSED TO HOT WATER. IF DESIRED, A HOSE MAY BE CONNECTED TO THE DRAIN VALVE TO CARRY THE WATER AWAY.
