I will be there and make sure I take pictures of all the reps and their products for our newsletter. Hope to see you at the next meeting. Gordy

Volume 24, No. 6 VICE PRESIDENT LEGISLATIVE One anonymous reader writes: Page 2 I have received one code related e-mail for the Legislative Open Forum Column. I actually received this e-mail back in October but have been quite busy with deadlines at work and unable to find the time to put a column together the past few months. I apologize for my lack of attention to my column. I m still pretty busy but figured even if I can t find time to research and comment on the question I better get it posted so perhaps others may comment on it if they wish. After all, the original concept of the column was to post the questions and comments and have others submit their two cents.so here we go. What is the sizing method required as prescribed by the 2009 plumbing Code, paragraph 1003.3.1 through 1003.3.5.? How do we arrive at the flow rate and retention time for sizing outdoor interceptor? New code language exception: 500 gallon and larger outdoor interceptor shall not be required to meet chapter 10 This new exception will likely default to size selection that only meets minimum Grand Rapids ordinance requiring a 1000 volume interceptor. I do feel that it is proper to default on the selection of a concrete outdoor G.I. that only meets minimum 1000 gallon Grand Rapids city ordinance. Various Food Service Establishments, i.e., Mom & Pop 25-Seat Restaurant, Fast Food Restaurants, Schools, 300 Bed Prison, 500 Bed Hospital, University Student Union Centers and Large Banquet Halls do not have the same flow rate, kitchen equipment, building drain line size, etc. The cleaning intervals necessary for a 1000 gallon G.I. to meet the effluent quality of 100mg/L, as required by the same ordinance, would be much more costly to maintain than a larger passive grease interceptor that is engineered, tested and certified. Signed, ASPE WMC Member Not a very exciting pen name but a topic for good discussion. Please feel free to comment. As stated previously, you may remain anonymous if you prefer.

RHEEM-RUUD COMMERCIAL WATER HEATERS Maximum delivery 460 gallons for one hour at 100 F rise 95% Thermal Efficiency Maximizes Energy Efficiency and Performance Dramatically reduces fuel costs Patented heat exchange system Eye level display for diagnostics and more! Commercial water heaters from Rheem-Ruud

SPIDERfire takes the bite out of fuel costs Rheem-Ruud INNOVATION SPIDERfire s unique multi-leg heat transfer system is where this new product gets its colorful name. The Rheem-Ruud line of condensing commercial water heaters offers a wide range of BTU inputs, all with ultra-high thermal efficiencies. The result is fuel savings and a higher recovery rate especially during periods of heavy use. The heart of the SPIDERfire is its patented heat-exchange system: a series of connected, elongated tubes immersed in the water tank and through which heat is transferred to the water. Generated by the burner at the top of the unit, combustion gases are blown down the large main flue in the center of the unit. The gases then traverse nearly the full length of the unit two more times, extracting as much heat energy as possible. By the end of the cycle, the temperature of the flue gases drops to between 110 F and 140 F and is cool enough for condensation to begin. Made in America Manufactured in Montgomery, Alabama, all SPIDERfire models come equipped with a 100- gallon storage tank and available in either natural gas or LP. Third-Party Tested The Rheem-Ruud SPIDERfire has been extensively tested by a third-party agency for water conditions and temperature, corrosive environments, dust and lint, increased cycling and venting configurations. Restaurants Hotels Laundromats Applications With its sleek modern design, the new SPIDERfire is engineered to deliver substantial amounts of hot water to meet the needs of larger commercial applications, such as restaurants, office buildings, schools, retail stores, and the like. SPIDERfire BENEFITS TO SPECIFYING ENGINEERS SPIDERfire offers ultra-high efficiency and energy savings. With up to a maximum delivery of 460 gallons, its performance will meet the needs of most businesses. Indoor air quality issues can be addressed by drawing combustion air from outside the building with a power direct vent installation. The SPIDERfire s small footprint reduces space requirements and long vent runs can be achieved through the use of low-cost PVC venting materials. TO CONTRACTORS SPIDERfire s narrow 26.25 inch diameter fits more easily down stairs and in tight places. Hot and cold water connections on both sides of the jacket provide flexibility during installation, especially during retro fits. The eye level status and diagnostic display is scrollable and reduces guess work, which helps speed up installation and service. Low-cost plastic venting materials can be used for power or power direct vent applications. TO FACILITIES MANAGERS Hot water is the second biggest energy user in most buildings, placing it right behind the HVAC system for energy costs. SPIDERfire s energy savings is an attractive solution to escalating costs. Because businesses often have heavy periods of hot water demand daily, SPIDERfire s ability to deliver up to 460 gallons for one hour helps keep you in business. In addition, the easy-to-read status and diagnostic display will help provide key information for fast installation and service. SPIDERfire s standard three year warranty can be increased to five years for additional piece of mind.

SPIDERfire s superb design is built to last Energy-efficient wet-base design SPIDERfire LCD diagnostic system provides scrollable diagnostics Rheem engineered a wet base for the lower portion of its flue system, suspending the first two legs of the flue network in water, rather than connecting them to the bottom of the tank. Hot spots are eliminated and the design also boosts efficiency heat is not lost through the bottom of the tank, as it is with a dry base design. Easier, less costly venting The cool temperatures of the flue gases permit venting through standard PVC or CPVC tubing. The low cost plastic venting means the contractor can install the product virtually anywhere, using almost any piping configuration. Depending on the model, an installer can use two-, three- or four-inch venting further lowering his costs and simplifying his installation. Power or power direct vent operation All models can be installed as a single-pipe, power-vented product; or as a two-pipe, power direct-vented product the latter for environments where negative air pressure or if indoor air quality is a concern. All inputs for SPIDERfire are available with ASME certification. Corrosion-protection SPIDERfire! Multi-leg heat exchanger system is porcelain coated inside and out Rheem coats the tubes inside and out with a specially formulated porcelain enamel designed to protect against the effects of condensation. Highly durable flue design The unique flue network of the SPIDERfire eliminates hot spots which can cause premature failure. It is built to last, even in heavy-commercial applications. OUR EXCLUSIVE FEATURES SPIDERfire LCD diagnostic system: This system is standard on all SPIDERfire units, enabling installers and service technicians to monitor key functions and components. LCD display is positioned at eye level offering easy-to-read status. The LCD s memory includes a scrollable, operational history to detail usage patterns and facilitate troubleshooting. Multiple water inlets and outlets: Two pairs of hot and cold water connections on either side of the water heater jacket provide installation flexibility, especially important in retrofit installations. Slim profile: Just 26.25 inches in diameter 1.5 to 2 inches smaller than competitive models the SPIDERfire fits more easily into tight commercial spaces. Full-port, full-flow brass drain valve factory installed: Allows for faster draining and servicing. Direct spark-to-flame ignition system Warranty: Standard three-year limited warranty can be upgraded to five years.
