2 TNR-I&S-02 W ARNING DO NOT A TTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT CER T AIN OF THE FOLLOWING: • Liquefied petroleum gases/propane gas and natural gas have an odorant added by the gas supplier that aids in detection of the gas. • Most people recognize this odor as a “sulfur” or “rotten egg” smell.
3 TNR-I&S-02 AIR REQUIREMENTS 1 . Do not obstruct the flow of combustion and ventilating air . 2 . For safe operation, adequate air is needed for combustion and ventilation. Sooting may result in serious damage to the water heater and risk of fire or explosion.
4 TNR-I&S-02 CAUTION If sweat fittings are to be used, DO NOT apply heat to the nipples in front or side of the water heater . Sweat the tubing to the adapter before fitting the adapter to the water connections. It is imperative that heat is not applied to the nipples containing a plastic liner .
5 TNR-I&S-02 from thermal expansion such as pressure bulges and/or deformities.Y our water supplier or local plumbing inspector should be contacted on how to control this situation. 3 . After installation of the water lines, open the main water supply valve and fill the water heater .
6 TNR-I&S-02 VENTING CAUTION The vent shall terminate a minimum of 12 inches above expected snowfall level to prevent blockage of vent termination. The horizontal centerline of the exhaust vent terminal (if applicable) must not be located lower than the horizontal centerline of the air intake terminal if vented through the same wall.
7 TNR-I&S-02 Direct V ent T erminal Location Plan the vent system layout so that proper clearances are maintained from plumbing and wiring. Before the vent is installed, determine the vent pipe termination location as shown below in Figure 10. Vent terminals must terminate at least 3 feet (0.
8 TNR-I&S-02 3 . For horizontal, the venting system shall terminate 4 foot below, 4 foot horizontally from or 1 foot above any door , window , or gravity air inlet into building. 4 . The manufacturer also recommends the vent system terminations not be installed closer than 3 feet from an inside corner of an L shaped structure.
9 TNR-I&S-02 Through The Wall Venting with Lo w 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 13).
10 TNR-I&S-02 Horizontal Installation: In a horizontal application, it is important that condensate not be allowed to buildup in the exhaust vent pipe.
11 TNR-I&S-02 COAXIAL VENTING INST ALLA TION PROCEDURE Vertical Installation (Recommended) 1 . Become familiar with coaxial vent kit. 2 . Determine the best location for the termination kit.
12 TNR-I&S-02 4 . Partially assemble vent kit by performing the following: a. Cement concentric Y fitting to larger diameter pipe. (See Figure 18). b. Cement rain cap to smaller diameter pipe. (See Figure 19). 5 . Install concentric Y fitting and pipe assembly through the structure’ s hole and field-supplied roof boot/flashing.
13 TNR-I&S-02 W ARNING DO NOT attempt to start this water heater until vent pipe solvent fumes completely clear from the room and inside the vent piping. VENT PIPE PREP ARA TION INITIAL PREP ARA TION 1 . Make sure the solvent cement you are planning to use is designed for the specific application you are attempting.
14 TNR-I&S-02 CAUTION The water heater and individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of ½ psi (3.
15 TNR-I&S-02 CAUTION Do not energize the electric circuit before the water heater tank is filled with water . This controller is Polarity sensitive. If the Hot and Neutral Supply voltage is reversed, the controller will not sense flame and the water heater will not operate.
16 TNR-I&S-02 LIGHTING INSTRUCTIONS Figure 24 Lighting Instruction Label.
17 TNR-I&S-02 TEMPERA TURE ADJUSTMENT The temperature selector knob of the thermostat has been adjusted to 120° F when shipped from the factory . During the winter season or any cold period, you may desire a higher temperature setting to adjust for the colder incoming water .
18 TNR-I&S-02 FLUSHING W A TER HEA TER 1 . T urn OFF the water heater electrical disconnect switch. 2 . Open the drain valve and allow water to flow until it runs clean. 3 . Close the drain valve when finished flushing. 4 . T urn ON the water heater electrical disconnect switch.
19 TNR-I&S-02 ANODE INSPECTION AND REPLACEMENT This water heater is equipped with multiple sacrificial anodes. Anodes protect the glass-lined tank from corrosion by sacrificing themselves through electrolysis. When the anode material is consumed, there is no more protection and corrosion of the tank accelerates.
20 TNR-I&S-02 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 Wire Harness.” If connections are ok, then replace the switch.
