RINNAI TANKLESS WATER HEATERS AWARDED ENERGY STAR DESIGNATION
(PEACHTREE CITY, Ga. – January 12, 2009) – Rinnai Corporation, the world’s largest gas appliance manufacturer and leading tankless water heater manufacturer, is proud to announce that six models from its line of tankless water heaters have earned the U.S. Department of Energy’s and Environmental Protection Agency's exclusive ENERGY STAR® rating for energy efficiency, including its flagship models, the R94LS and R75LS. Rinnai’s ENERGY STAR qualified products highlight the company’s ongoing commitment to the development and adoption of new energy-efficient technologies, which provide its customers with choices that are both economically and environmentally responsible.
“Water heating presently accounts for 15.5 percent of national residential energy consumption, making it the second-largest energy user in homes,” said Phil Weeks, general manager of Rinnai America Corporation. “With rising energy costs and a continued commitment to environmental stewardship, consumers are focused more than ever before on maximizing their homes’ energy efficiency. By developing ENERGY STAR qualified tankless water heaters, Rinnai is helping consumers save money while simultaneously decreasing their carbon footprint.”
Products seeking ENERGY STAR qualification must meet the program’s strict energy efficacy guidelines. In order to be deemed ENERGY STAR qualified, tankless water heaters must maintain a minimum Energy Factor (EF) of 0.82 and a minimum gallons-per-minute flow of 2.5 at a 77-degree Fahrenheit rise. A whole-home gas tankless water heater that meets these requirements is expected to reduce energy use by 30 percent, which can save a consumer approximately $108 in annual energy costs when compared to a typical gas storage water heater.
Rinnai pioneered the process to get the ENERGY STAR designation for tankless water heaters. “Until now, water heaters were the only major residential energy end use without an ENERGY STAR designation,” said Alliance to Save Energy President Kateri Callahan. “Rinnai recognized the benefits an ENERGY STAR designation would bring to residential water heating and played an integral part in the U.S. Department of Energy’s April 2008 decision to establish an ENERGY STAR program for the category.”
In addition to meeting the ENERGY STAR guidelines, Rinnai’s tankless technology possesses other features that both reinforce and enhance its energy efficacy. Unlike traditional tank-style water heaters, which heat and reheat water around the clock, tankless water heaters only produce hot water when needed, shutting off immediately afterwards to eliminate wasted energy. Additionally, Rinnai tankless water heaters last more than twice as long as traditional tank-style models and are constructed of 95 percent recyclable materials, drastically cutting the number of water heaters deposited in landfills each year. By investing in a tankless water heater, consumers can reduce their output of greenhouse gases and conserve otherwise wasted energy, thus decreasing their negative impact on the environment.

Algas-SDI Vaporizer Safety
In order to safely service and work on a vaporizer, it is important to properly purge the unit of any propane (liquid and vapor). Algas-SDI has created a step by step procedure to help ensure your safety. Click here for this procedure.
Algas-SDI Direct Fired Vaporizer Bulletin
In 2002, Algas-SDI implemented a design change on the Algas style direct fired vaporizers. As part of the engineering of this change, the burners now require a different operating pressure depending on the model. The following Engineering Bulletin provides the details on the pressure requirements and procedure for setting the proper burner pressure. Click here for this bulletin.

VENT FREE GAS PRODUCTS - PILOT TROUBLESHOOTING TIP
Provided by Rassmussen Fireplace Log Company
a) Unable or difficult to establish the pilot light; or
b) Burner(s) and/or pilot shuts down after a few minutes of operation.
The ODS Pilot has two small holes that draw in air to mix with the gas to create a stable pilot flame. Unfortunately, over time lint and dust in the air accumulate inside these holes, which disrupt the proper operation of the pilot flame.
Action to Take:
1) Gather tools needed: A vacuum cleaner with brush attachment. A can of compressed air with a tube (the type that is used to clean computer keyboards) or a drinking straw.
2) Vacuum up all lint, dust & debris from logs, grate, burner(s), burner air intake, and air shutter regions (underneath burner, where air gets drawn in), and pilot area.
3) Using the compressed air or a straw, blow out burner ports (where the main flame comes from), burner air intake and air shutter regions (end of burner(s) where gas and air mix), around the valve knob (the one you depress to light the pilot), and MOST IMPORTANTLY, the air intake holes of the ODS Assembly. These small air intake holes are between 1/16" and 1/8" in diameter and are located about 2" from the end of the pilot from where the pilot flame originates. Use the compressed air or straw to blow out these holes.

VAPORIZATION "RULE OF THUMB" FOR ASME TANKS
Source: Sherwood LPG Products Liquified Petroleum Gas Control Technician's Guide
The vaporization rate is a factor of (1) the temperature of the liquid and (2) the "wetted surface" area of the container. This applies to bulk installations equally as well as it does to cylinder systems.
In estimating the size tank required for any given load, it is necessary to decide on an average, or point at which the gas supplier will refill the tank. Of course, our minimum vaporation rate will occur when the liquid level is the lowest. On the assumption that the tank will be refilled when the liguid level drops to 1/3 the fuel capacity of the tank, the following table will give you a good "rule of thumb" guide for various temperatures.
NOTE: The physical dimensions of the tank actually affect its vaporization rate. A small diameter, long tank makes a better vaporizing tank than a large diameter, short tank of equal gallonage. This is due to more square inches of surface area in the tank of smaller diameter. A sphere would have the minimum number of square inches of surface area per gallon of fuel, and consequently, the poorest vaporization factor. Thus the above table represents a conservative figure, recognizing that there will be some variation in vaporizing rates due to the physical differences in tanks of same gallonage.
Here is an example of how to use this "rule of thumb" for your bulk tanks: Suppose we had a tank 40" in diameter and 105" long and our worst winter temperature was 0 degrees F. The tank rarely drops below the 1/3 full mark. Would this tank under these circumstances, supply a continuous load of 350,000 BTU's an hour?
The "rule of thumb" would tell us that it would supply this load requirement 40" (D) X 105" (U) X 90 (taken from the table above, opposite 0 degrees F) = 378,000 BTU's.
Don't blame regulators for improper operation if the systems are operated with insufficient fuel storage. Regardless of the size of a regulator, it can't make pressure.
