INSTALLATION INSTRUCTIONS 4. Attach a hose to the water heater drain valve and put the other end in a floor drain or outdoors. Open the water heater drain valve. Open a nearby hot water faucet which will relieve pressure in the water heater and speed draining. The water passing out of the drain valve may be extremely hot. To avoid being scalded, make sure all connections are tight and that the water flow is directed away from any person, see Figures 2 and 5. Removing the Old Water Heater FIGURE 5. 5.
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. FIGURE 8. Whether replacing an old water heater or putting the water heater in a new location, the following critical points must be observed: 1.
and 12” (30.5 cm) from the top. (Standard clearance.) If clearances stated on the heater differ from standard clearances, install water heater according to clearances stated on the heater. in many cases, will also react to form corrosive hydrochloric acid when exposed to the combustion products of the water heater. The results can be hazardous, and also cause product failure. Adequate clearance for servicing this appliance should be considered before installation, such as changing the anodes, etc.
3. When communicating with the outdoors through horizontal ducts, each opening shall have a minimum free area of 1 square inch per 2,000 Btu per hour (11 cm2/kW)) of total input rating of all equipment in the enclosure, see Figure 14. Chemical vapor corrosion of the flue, blower assembly and vent system may occur if air for combustion contains certain chemical vapors.
WATER PIPING Toxic chemicals, such as those used for boiler treatment shall not be introduced into this system. When the system requires water at temperatures higher than required for domestic water purposes, a tempering valve must be installed. Please refer to Figure 15 for suggested piping arrangement.
TEMPERATURE-PRESSURE RELIEF VALVE INSTALLATION COMPLETED USING INSTALLATION KIT This heater is provided with a properly certified combination temperature - pressure relief valve by the manufacturer. The valve is certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment of materials as meeting the requirements for Relief Valves for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4, and the code requirements of ASME.
If the main gas line Shut-off serving all gas appliances is used, also turn “off” the gas at each appliance. Leave all gas appliances shut “off” until the water heater installation is complete. The Discharge Pipe: • Shall not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other restrictions. • Shall not be plugged or blocked. • Shall be of material listed for hot water distribution.
The appliance and its gas connection must be leak tested before placing the appliance in operation. The appliance and its individual Shut-off valve shall be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 pound per square inch (3.5 kPa).
7. Do not plug in power cord until vent system is completely installed. This power vent heater operates on 110-120 Vac, therefore a grounded outlet must be within reach of the six (6) foot (1.8 m) flexible power cord supplied with the unit (see Figure 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: 4. Make sure that the plastic tubing is still attached from the air pressure switch to the port on the blower housing.
pipe is NOT ALLOWED. If 2” pipe is to be used, then a 2” to 3” bell reducer is recommended. Figure 21 shows the recommended location for the bell reducer. If the bell reducer is located at the rubber boot on the blower assembly, then a short section of 3” vent pipe needs to be installed in the rubber boot for proper connection of the 2” to 3” bell reducer. That length can be the minimum length required for the connection.
Vent pipes serving power vented appliances are classified by building codes as “vent connectors”. Required clearances from combustible materials must be provided in accordance with information in this manual under FACTS TO CONSIDER ABOUT THE LOCATION and VENT TERMINAL INSTALLATIONS, and with the National Fuel Gas Code and local codes. VENTING VENT TERMINAL INSTALLATION 1.
FIGURE 23. This unit can vent through 2”, 3” or 4” nonmetallic pipe and fittings. VERTICAL VENT TERMINATION RESTRICTIONS The vent pipe installation can be started from either the blower discharge or the termination wall. Keep in mind the total vent system (pipe and elbows) when installing the vent system, see VENTING AND INSTALLATION AND MAXIMUM VENT LENGTHS, page 17. 1. Minimum of twelve 12” (30.5 cm) above the roof or twelve 12” (30.5 cm) above the anticipated snow level.
solvated with tetrahydrofuran (THF). Small quantities of dimethyl formamide (DMF) may be included to act as a retarding agent to extend curing time. Select the proper cement; Schedule 40 cement should be used for Schedule 40 pipe. Never use all-purpose cements, commercial glues and adhesives or ABS cement to join PVC or CPVC pipe and fittings. VENT PIPE PREPARATION 1. INITIAL PREPARATION A. Make sure the solvent cement you are planning to use is designed for the specific application you are attempting.
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° should be added to the end to permit easier insertion of the pipe into the end of the fitting. Failure to chamfer the edge of the pipe may remove cement from the fitting socket, causing the joint to leak. STEP E F.
OPERATING INSTRUCTIONS FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. FLAMMABLE BEFORE OPERATING: ENTIRE SYSTEM MUST BE FILLED WITH WATER AND AIR PURGED FROM ALL LINES. If you cannot reach your gas supplier, call the A. This appliance does not have a pilot. It is equipped with an ignitiion device which automatically lights the fire department. burner.
1. “Wake Up” the temperature indicators by holding down both “COOLER” and “HOTTER” temperature adjustment buttons at the same time TEMPERATURE REGULATION Due to the nature of the typical gas water heater, the water temperature in certain situations may vary up to 30°F (16.7°C) higher or lower at the point of use such as, bathtubs, showers, sink, etc. for one second, see Figure 26. One or two of the temperature indicators will light up.

A water heater may appear to be leaking when in fact the water is condensate. This usually happens when: a.
STRANGE SOUNDS Possible noises due to expansion and contraction of some metal parts during periods of heat-up and cool-down do not necessarily represent harmful or dangerous conditions. “AIR” IN HOT WATER FAUCETS Condensation causes sizzling and popping within the burner area during heating and cooling periods and should be considered normal. See “Condensate” in this section.
At least once a year a visual inspection should be made of the main burner and the hot surface igniter assembly for proper flame characteristics and ignition sequences. This can be done by removing the Outer Door and viewing the main burner operation through the Viewport on the Inner Door, see Figure 1. The main burner should provide complete combustion of gas, ignite rapidly, give reasonably quiet operation, and cause no excessive flame lifting from the burner ports.
5. OPEN the water heater drain valve to allow for tank draining. NOTE: If the water heater is going to be shut down and drained for an extended period, the drain valve should be left open with hose connected allowing water to terminate to an adequate drain. 6. CLOSE the drain valve. 7. Follow instructions in the “Filling The Water Heater” section. 8. Follow the lighting instructions on the label or see page 22 under “Operating Instructions” to restart the water heater. FIGURE 30.
LEAKAGE CHECKPOINTS 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. Read this manual first. Then before checking the water heater make sure the gas supply has been turned “OFF”, and never turn the gas “ON” before the tank is completely full of water.
