5 General Safety Precautions To meet commercial hot water requirements, the tankstat is adjustable up to 190°F. However, water temperatures over 125°F. can cause severe burns instantly or death from scalds. This is the preferred starting point for setting the control for supplying gen- eral purpose hot water. Safety and energy conservation are fa[...]

3. INSTALLATION PROCEDURES CODE REQUIREMENTS Installation must be in accordance with local codes , or, in the absence of local codes, with the latest editions of the National Fuel Gas Code , ANSI Z223.1,/NFPA 54, and the National Electrical Code , ANSI/NFPA 70. In Canada installations must conform with the current CAN/CSA B149.1 and the Canadian El[...]

1 ) The heater must be provided with adequate supply of air for proper combustion and ventilation in accordance with the latest edition of the National Fuel Gas Code , ANSI Z223.1, or applicable provi sions of the local building codes. 2 ) When the heater is installed in a confined space where all air is supplied from inside the building, the heate[...]

VENTING CONNECTIONS (Indoor Models) The drafthood is shipped separately and must be installed on the heater. For Model 260/261: 1. Mount drafthood on top of heater and attach with the 4 sheet metal screws provided. Drafthood should be positioned with the vent sensor located on the front left side as shown. 2. Remove plastic plug from left side of h[...]

9 Gas vents supported only by the flashing and extend- ing above the roof more than five feet should be securely guyed or braced to withstand snow and wind loads. We recommend use of insulated vent pipe spacer through the roofs and walls. For protection against rain or blockage by snow, the vent pipe must terminate with a listed vent cap which comp[...]

10 WARNING: These heaters must not be connected into any portion of mechanical draft systems operating under positive pressure. To do so may cause the flue products to be discharged into the living space causing serious health injury. For connections to gas vents or chimneys, vent installations shall be in accordance with Part 7, Venting of Equipme[...]

CAUTION: The heater and its manual shut off valve must be disconnected from the gas supply during any pressure testing of that system at test pressures in excess of 1/2 PSIG(3.45 KPA). Dissipate test pressure in the gas supply line before reconnecting the heater and its manual shut off valve to gas supply line. FAILURE TO FOLLOW THIS PROCEDURE MAY [...]

When this water heater system is supplying general purpose hot water requirements for use by individuals, a thermostatically controlled mixing valve is recommended to reduce the risk of scald injury. Contact a licensed plumber or the local plumbing authority for further information. Thermometer(s) should be installed so that they indicate the water[...]

13 ELECTRICAL WIRING The electrical power supply requirement for these heaters is 115 volts, 60 Hz. Field wiring connections and electrical grounding must comply with the local codes, or in the absence of local codes, with the latest edition of the National Electrical Code, ANSI/NFPA 70. Provide a separate fused circuit from the main electrical pan[...]

4. SERVICING PROCEDURES SEQUENCE OF OPERATION INTERMITTENT IGNITION DEVICE (IID) Heaters equipped with the IID system will automatically light the pilot burner first and then the main burner, each time there is a call for heat from the tankstat. Whenever the tankstat calling for heat, the circulator supplied with the heater, will be energized and s[...]

A . This heater has a pilot which must be lighted by hand. When lighting the pilot, follow these instruc- tions exactly. B. BEFORE LIGHTING smell all around the heater area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor. WHAT TO DO IF YOU SMELL GAS • Do not try to light any appliance.[...]

6. Wait five (5) minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow "B" in the safety information above on this label. If you don't smell gas, go to the next step. 7. Locate pilot mounted on the right side of the burner drawer, right of first burner. 8. Turn knob on gas control [...]
