GENERAL SAFETY T o meet commercial hot water use needs, the high limit safety control on this water heater will shut off the main gas valve before the outlet temperature reaches 210°F . However , water temperatures over 125°F can cause instant severe burns or death from scalds.
INST ALLA TION INST ALLA TION Installation Codes Installations must follow these codes: · Local, state, provincial, and national codes, laws, regulations and ordinances. · National Fuel Gas Code, ANSI Z223.1- latest edi- tion (NFGC). · National Electrical Code, ANSI/NFP A 70 - latest edition (NEC).

WARNING: Do not use one permanent opening method if the equipment room is under negative pressure conditions or the equipment is common vented with other gas-fired appliances. 1. V entilation of the space occupied by the heater shall be provided by an opening(s) for ventilation air at the highest practical point communicating with outdoors.
13 WARNING: Pressure relief valve discharge piping must be piped near the floor and close to a drain to eliminate the potential of severe burns. Do not pipe to any area where freezing could occur .
14 Low T emper a tur e System Heater requires minimum inlet temperature of 105°F . Consult the following sections for piping details. T emperature & Pr essure Gauge The temperature and pressure gauge is shipped loose for field installation.

(System head loss is based on the heater and tank placed no more than 5 feet apart and 50 feet equivalent length of tubing and fittings.
17 Gas Supply Connection CA UTION: The heater and its manual shutoff valve must be disconnected from the gas supply during any pressure testing of the gas supply system at test pressures in excess of 1/2 psi (3.
18 Fig. 13: Sediment T rap Orientation Gas Supply Pr essure A minimum of 4 in. WC and a maximum of 10.5 in. WC upstream gas pressure is required under load and no load conditions for natural gas. A minimum of 1 1 in. WC and a maximum of 13 in. WC is required for propane gas.
19 Install a separate disconnect means for each load. Use appropriate-sized wire as defined by NEC, CSA and/or local code. All primary wiring should be 125% of minimum rating. It is strongly recommended that all individually-pow- ere d contr ol mod ules an d the hea ter sh ould be supplied from the same power source.

40 F ollo w-Up • Safety checks must be recorded as performed. • T urn unit on. After main burner ignition: • Check Manometer(s) for proper reading(s). • Cycle unit several times and recheck readings. • Re-analyze with unit running record or print results.
41 3. Remove the (4) screws holding the panel in place. 4. Pull the air filter out for inspection. Replace if nec- essary . 5. When replacing, note the direction of the air flow defined on the side of the filter . The arrow should be pointing downward.
heater operating efficiency . Maintenance as outlined below may be performed by the owner . Y ear l y (Beginning of eac h heating season): 1. Annual service call by qualified service agency .
43 2. Visually check top of vent for soot. Call service person to clean. Some sediment at bottom of vent is normal. 3. Visually inspect venting system for proper func- tion, deterioration or leakage. 4. Check that heater area is free from combustible materials, gasoline, and other flammable vapors and liquids.
