© 2007 by The Taunton Press, Inc. ISBN 10 1-56158-839-3 ISBN 13 978-1-56158-839-8 Code Check'" is a trademark of The Taunton Press, Inc., registered in the U.S. Patent & Trademark Office. Printed in China Code Check is a field inspection guide to important code requirements and common code violations in the construction of singlefamily and two-family dwellings. The primary reference document for this book is the 2006 edition of the International Residential Code'" for One- and Two-Family Dwellings, published by the International Code Council. Codes are adopted at different times in different places around the country. New editions come out every three years, and some states make extensive modifications to the model codes prior to adoption. Because the actual code that is used in a particular area could vary, we include references to the two most commonly used codes for every item in the book. Significant code changes have been noted and are included in a summary on the inside back cover. This feature enables the book to be used in areas still using the previous code edition. To determine the particular codes in effect in your area, contact your local building department before beginning your project. For more information on the building, electrical & mechanical codes, valuable resources, & why Benjamin Franklin is featured in the Code Check series, visit: www.codecheck.com

The code changes referenced on the inside back cover compare the codes in this table to the 2003 IRe, UPC, UMC & 2002 NEC

PROCEDURES FOR SIZING GAS PIPE

TABLE 23

[2413.4.1,2] & {1211.17.1.1 ,2}

CSST Manifold

1. Determine Btu/cu.ft. gas from local supplier (usually 1,100). 2. Divide appl Btu by Btu/cu.ft. to obtain appl demand.

1/4-turn ball valve

3a. Longest length method: Measure developed length to most remote outlet. 4a. Longest length method: Use column from T25 for most remote fixture for all outlets. 3b. Branch length method: Measure developed length to each outlet. 4b. Branch length method: Select column from T25 for load on piping to each outlet. 5. Select row for pipe size equal ing or exceeding demand each section.

CSST is regulated by American National Standards Institute ANSI / lAS LC 1-1997/ CSA 6.26-M97 Fuel Gas Piping Systems Using Corrugated Stainless Steel Tubing (CSST). The standard requires that a contractor be certified before installing CSST.

Temperature & Pressu re-Relief Valve

{NEC} When the water heater is in a basement or below grade, it may not be possible to arrange for a gravity drain of the T&P valve. A Watts 210 valve (F45) can be installed. The temperature-sensing bulb of the valve goes in the upper portion of the tank & the gas piping runs through the valve. The Watts 210 shuts off the gas if the temperature is excessive. In addition, a separate water-pressure-relief valve (F4S) must be installed in the piping & must drain by gravity to an approved location. Check with the local Administrative Authority to see if this method is accepted in your area.

Combination TPRV {req 'd} OR F43, 44 [2S03.1] {506.2,60S.3} Separate TRV (Watts 210 valve) and PRV F45, 46 _ [2S03.1] {505.4,5} Watts 210 also req 's pressure relief valve F46_ _ _ [2S03.1] {505.6} Locate TPRV [in top 6in of tank] {per manu} F42_ [2S03.4, 5] {505.6,60S.3}

Gas Appliance Vent Terminations

Vent Offsets

If vent is closer than Sft. to the wall, the vent must terminate at least 2ft. above the roof edge. Appl iance manufacturers su pply venti ng tables giving max Btu capacity for different sizes, lengths & offsets. When the offset includes more than 2 90° bends, subtract 5% from the table capacity for each elbow up to 45° & 10% for each elbow up to 90°.

Ceiling When not using the tables, 1 60° offset 0 K & flue offsets ~45° OK if total horiz. length of connector & vent ~ 75 % of height.

Subpanel Bonding In a downstream subpanel, the white neutral & the equipment grounds must not be bonded together. The neutral MUST be insulated from contacting the metal enclosure & any equipment grounds.

3 This section req's a 1.5 safety factor in design of unrestrained retaining walls. For basement walls to be considered laterally supported: The floor slab must now restrain basement walls, AN D The floor system must be connected to the sill with hardware per a new table, AND The sills must be bolted to the walls per a new table, AND The floors must be blocked full depth within two joist spaces of the wall, AN D Aspect ratios of bldgs with unbalanced loads must be within values of a new table.

9. Dampproofing membranes can be approved if made for CMU w/o parging. 10. Reinforcement must be secured in place, not merely thrown into wet concrete. 11. Reduction to 10% of req'd venting if vapor retarder present has been deleted. 12. Conditioned crawl spaces can now be approved for perimeter insulated crawl space. Page 4 13, Manufacturer's instructions OK for cutting, notching & boring . Page 5 14. Joints in top plates no longer req over studs. Page 6 15. HIB-91 replaced by BCSll-03. 16.

14 The req 'd distance past the framing edge is new in the 2006 U PC. The requ irement depends on the floor level of the fixt, not th e fixt floor. C leanouts must be the same size as the pipe served in the IRC.

15 The height above the roof is specified instead of a blank to be filled in by the AHJ. The specified case of a "vertical leg waste fixture drain" has been deleted. The 2003 U PC did not allow any horiz wet venting. This section clarifies where horiz wet vents are allowed.
