The temperature-pressure relief valve must be manually operated at least once a year , see Figure 28. Caution should be taken to ensure that (1) no one is in front of or around the outlet of the temperature-pressure relief valve discharge line, and (2) the water manually discharged will not cause any bodily injury or property damage because the water may be extremely hot.

If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions, and replace the temperature-pressure relief valve with a new one.

Gas Piping

Make sure gas supplied is same type listed on model rating plate. The inlet gas pressure must not exceed 14 inch water column (3.5 kPa) for natural and propane gas (L.P.). The minimum inlet gas pressure shown on rating plate is that which will permit firing at rated input.

All gas piping must comply with local codes and ordinances or with the National Fuel Gas Code (ANSI Z223.1/ NFPA-54) or the Natural Gas and Propane Installation Code (CAN/CSA B149.1) whichever applies. Copper or brass tubing and fittings (except tin lined copper tubing) shall not be used.

If the gas control valve is subjected to pressures exceeding 1/2 psi (3.5 kPa), the damage to the gas control valve could result in a fire or explosion from leaking gas.

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.

A gas line of sufficient size must be run to the water heater.

Consult the current edition of National Fuel Gas Code

(ANSI Z223.1/NFPA 54) or the Natural Gas and Propane Installation Code (CAN/CSA B149.1) and your gas supplier concerning pipe size.

There must be:

•A readily accessible manual shut off valve in the gas supply line serving the water heater, and

•A drip leg (sediment trap) ahead of the gas control valve to help prevent dirt and foreign materials from entering the gas control valve.

•A flexible gas connector or a ground joint union between the shut off valve and control valve to permit servicing of the unit.

Be sure to check all the gas piping for leaks before lighting the water heater. Use a soapy water solution, not a match or open flame. Rinse off soapy solution and wipe dry.

HIGH ALTITUDE INSTALLATIONS

Rated inputs are suitable up to 10,100 feet (3,079m) elevation. Consult the factory for installation at altitudes over 10,100 feet (3,079m).

WARNING: THIS HIGH EFFICIENCY WATER HEATER IS CERTIFIED FOR USE WITHOUT MODIFICATION FOR AN ALTITUDE OF 10,100 FEET (3,079 METERS). INSTALLATIONS ABOVE THESE ALTITUDES MAY REQUIRE REPLACEMENT OF BURNER ORIFICE. CALL THE TECHNICAL CENTER AT (800) 527-1953 FOR REQUIREMENTS.

Some gas utility companies derate their gas for altitude, making it unnecessary to install high altitude orifices. Call the local gas or utility company to verify BTU content.

Due to the input ration reduction at high altitudes, the output rating of the appliance is also reduced and should be compensated for in the sizing of the equipment for applications.

Use pipe joint compound or teflon tape marked as being resistant to the action of petroleum [Propane (L.P.)] gases.

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). It shall be isolated from the gas supply piping system by closing its individual manual Shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 pound per square inch (3.5 kPa).

Important: Make sure the gas line is piped in with hard pipe. Avoid flex line construction for gas due to possible gas flow problems.

Power Vent/Power Direct Vent Gas Models specifications

State Industries offers a range of power vent and power direct vent gas models that cater to various residential and commercial heating needs. These models are designed for efficiency, safety, and convenience, making them a popular choice among consumers seeking reliable water heating solutions.

One of the standout features of State Industries' power vent models is their ability to vent directly through walls or roofs, enabling installation in locations where traditional venting methods may pose challenges. This flexibility makes them ideal for homes without suitable chimney access. The power vent system employs a fan to push exhaust gases out, ensuring efficient operation even in cases where vertical venting is not feasible.

The power direct vent models take this a step further by utilizing sealed combustion technology. This means they draw air for combustion from outside the home, which significantly reduces the risk of backdrafts and improves indoor air quality. The dual-venting system of these models also enhances their efficiency, as it allows for better control of air flow and exhaust.

State Industries incorporates advanced technologies in their gas models, including electronic ignition systems that eliminate the need for a standing pilot light. This feature not only enhances energy efficiency but also adds convenience for users. Moreover, these models come equipped with LED indicators that provide real-time status updates, enabling users to monitor their units easily.

Durability and reliability are hallmarks of State Industries products. The tanks are constructed with high-quality materials and feature protective coatings that inhibit corrosion, ensuring a long lifespan. In addition to this, many models are backed by extended warranties, providing peace of mind for consumers.

Energy efficiency is a critical characteristic of these gas models, with many units meeting or exceeding energy efficiency standards set by the Environmental Protection Agency (EPA). This results in lower utility bills and a reduced environmental impact. With adjustable temperature settings, users can optimize their water heating experience while conserving energy.

In conclusion, State Industries' power vent and power direct vent gas models stand out for their flexibility in installation, advanced technologies, and energy-efficient operation. Whether for residential or commercial use, these models offer high performance and reliability, ensuring that users enjoy a consistent and efficient hot water supply.
