16 SCALDING This water heater can deliver scalding temperature water at any faucet in the system. Be careful whenever using hot water to avoid scalding injury. Certain appliances such as dishwashers and automatic clothes washers may require increased temperature water.
17 ALTERNATE SPACE HEATING WATER CONNECTIONS DANGER Toxic chemical, such as those used for boiler treatment, shall not be introduced into potable water used for space heating. This water heater shall not be connected to an existing heating system or component(s) previously used with a no n - potable water heating appliance.
18 Figu re 11 . Typical Plumbing Schematic for Zoned Heating SECTION VI: VENTING WARNING The vent system must be properly installed. Failure to properly install the vent system could result in property damage, pers onal injury, or death. DO NOT install damaged venting system components.
19 NOTICE Before beginning installation of any vent pipe, read the vent pipe manufacturer’s installation instructions. Water heater must be protected from freezing downdrafts during shutdown periods Provide protection of the building materials from degradation by flue gases from the exhaust vent terminal.
20 Vent terminals must terminate at least 3 feet (0.9 m) above any forced air inlet located within 10 feet (3.1 m). This provision does not apply to: 1. The combustion air intak e of a direct vent appliance or the circulating air inlet and flue gas discharge of listed outdoor appliances.
21 NOTICE This unit can be vented using only PVC (Class 160, ASTM D - 224 1 Schedule 40, ASTM D - 1785; or Cellular Core Schedule 40 DWV, ASTM F - 891), Schedule 40 CPVC (ASTM F - 411), or ABS (ASTM D - 2661) pipe. The fittings, other than the TERMINATIONS should be equivalent to PVC - DWV fittings meeting ASTM F - 2665.
22 Figure 13 . Typical Horizontal Direct Vent System Vertical Installation: Vertical venting system must be supported every 5 feet of vertical run and every 3 feet of horizontal run of vent pipe length. Stress levels in the pipe and fittings can be significantly increased by improper installation.
23 Figure 14 . Typical Vertical Direct Vent System Installation Through The Wall Venting With Low Ground Clearance: When venting cannot exit through the wall at a height greater than or equal to 12” (30.5 cm) (and above expected snow level) from the ground, then the installation must be modified as shown below (see Figure 15).

25 Horizontal Installation: In a horizontal application, it is important that condensate not be allowed to buildup in the exhaust vent pipe. To prevent this from happening, the pipe sh ould be installed with an slight upward slope.
26 Follow the following procedure to vent through the roof: 1. Cut the necessary holes through the roof and ceiling 2. Install the exhaust vent and air intake plastic pipes as shown in Figure 17. Make sure that the insta llation meets the local codes and/or The National Fuel Gas Code ANSI Z223.

28 shock can cause personal injury or death. DO NOT operate this water heater with the rain cap removed or recirculation of combustion products may occur.
29 5. Install concentric Y fitting and pipe assembly through the structure’s hole and field - supplied roof boot/flashing. Do not allow insulation or other materials to accumulate inside pipe assembly when installing through the hole.
30 b. Cement rain cap to smalle r diameter kit pipe. (See Figure 21). 5. Install concentric Y fitting and pipe assembly through the structure’s hole and field - supplied roof boot/flashing. Do not allow insulation or other materials to accumulate inside pipe assembly when installing through the hole.
31 SELECTION OF MATERIALS PRIMER – It is recommended that Tetrahydrofuran (THF) be used to prepare the surfaces of pipe and fittings for solvent welding. Do not use water, rags, gasoline or any other substitutes for cleaning PVC cellular core, ABS or CPVC surfaces.
32 Figure 24 . Drip Leg The gas supply lines must meet all requirements of the National Fuel Gas Code ANSI Z223.1 (Late st Edition), or in Canada CAN/CGA B149.1 Natural Gas Installation Code (Latest Edition) or CAN/CGA B149.2 Propane Installation Code (Latest Edition).
33 SECTION VIII: ELECTRICAL CONNECTIONS WARNING Turn off or disconnect the electrical power supply to the water heater before servicing. Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.
34 SECTION IX: OPERATING INSTRUCTIONS WARNING Water heaters are heat - producing appliances. To avoid damage or injury there must be no materials stored against the water heater or direct vent system, and proper care must be taken to avoid unnecessa ry contact (especially by children) with the water heater and direct vent system.
35 LIGHTING INSTRUCTIONS Figure 26 . Lighting Instruction Label TEMPERATURE ADJUSTMENT The temperature selector knob of the thermostat has been adjusted to 120°F when shipped from the factory.
36 During the winter season or any cold period, you may desire a higher temperature setting to adjust for the colder incoming water. This adjustment, however, may cause additional condensation to form on the colder tank surface. This does not mean the tank is leaking.
37 SECTION X: MAINTENANCE DANGER DO NOT ATTEMPT TO REPAIR GAS VALVE. DO NOT A TTEMPT TO REPAIR IGNITION MODULE. DO NOT ATTEMPT TO REPAIR VENTURI. DO NOT ATTEMPT TO REPAIR THERMOSTAT BOARD. DO NOT ATTEMPT TO REPAIR TRANSFORMER. DO NOT ATTEMPT TO REPAIR PRESSURE SWITCH.
38 FLUSHING WATER HEATER 1. Turn OFF the water heater electrical disconnect switch. 2. Open the drain valve and allow water to flow until it runs clea n. 3. Close the drain valve when finished flushing. 4. Turn ON the water heater electrical disconnect switch.
39 To remove sediment and lime scale: 1. Drain the heater. Refer to DRAINING THE WATER instructions in this section. 2. Remove outer cover plate from lower side of water heater jacket. 3. Remove cover and gasket from cleanout opening. 4. Remove lime, scale or sediment using care not to damage the glass - lining.
40 A t least twice a year, the temperature and pressure relief valve should be checked to ensure that it is in operating condition. To check the relief valve, lift the lever at the end of the valve several times. The valve should seat properly and operate fre ely.
41 S ECTION XI: TROUBLESHOOTING GUIDE Main power light is not lit. Make sure that water heater is plugged in. When the switch is on, is there 120VAC between L1 and N on the terminal block? If not, then check for loose wire connections on the “Power Switch W ire Harness.
42 Is there continuity across the “Hot Surface Ignitor?” If no, then replace hot surface ignitor. If yes, then replace the ignition module. Main valve does not turn on Put your hand on the gas valve.
