1 Module number 8 provides an on-line, self-paced training seminar on portions of Chapter 14-Fuel Gas, Chapter 25-Ohio Plumbing Code; Chapter 29-Fire Suppression Systems; and Chapter 34-National Electric Code. 1

2 This chapter sets forth the requirements for the installation of gas piping and gas appliance installation and gas appliance venting systems. 2

3 The definition of Point of Delivery is added in order to determine the location in a gas piping system where the Fuel Gas code becomes effective. The Fuel Gas code regulates all portions of the fuel gas system downstream of the Point of Delivery. 3

4 An approved pan is required under fuel gas appliances that create condensation that could cause building damage in the event of leakage or a blockage in the condensate drainage system. 4

5 Gas-fired appliances may be installed at floor level within enclosed spaces in a garage so long as that enclosed space has access only from outside of the garage and all combustion air is taken directly from the outdoors. 5

6 Gas piping shall be installed so as to not strain the piping or connections at appliances. The piping must be properly aligned and adequately supported. 6

7 All gas piping must be bonded to an effective ground-fault current path; however CSST gas piping must only be bonded to the building s electrical service grounding electrode system. 7

8 Regulator vent piping may be PVC only when installed outdoors. All regulator vent piping is to be installed per the regulator manufacturer s installation instructions. 8

9 Gas piping downstream of the Point of Delivery may not pass through any townhouse unit other then the unit served by such piping. The definition of townhouse is important in the application of this section. 9

10 Gas piping is no longer permitted to penetrate the foundation wall of a building below ground. 10

11 When both ends of a protective conduit installed in a slab terminate inside the building, the code prohibits the ends from being sealed. 11

12 The open ends of a conduit protecting gas piping that passes under the slab from one point in a building to another point within the building must extend above the floor at least two inches and may not be sealed. 12

13 This section of code recognizes the hazards in clearing fuel gas from existing lines and establishes criteria for the safe release. 13

14 When a manifold gas piping distribution method is installed, a new provision permits the appliance shutoff valve to be located at the manifold so long as it is not greater than 50 feet from the appliance. 14

15 The Maximum length of all connectors may not exceed 6 feet. 15

16 A minimum clearance of 24 inches is permitted when one of the following conditions exist as shown on next slide: 16

17 Clearance requirements for household cooking appliances have been added to the fuel gas codes requiring a minimum clearance of 30 inches from the cooking top to the underside of combustible material or metal cabinets. Specific exceptions are permitted to reduce the clearance to 24 inches minimum. 17

18 This chapter refers the user to the current Ohio Plumbing Code (OPC) for the installation, testing and operation of plumbing systems, with very few modifications. 18

19 Modifications to the plumbing code delete the requirement for a shower liner test and eliminate the need for a trap seal primer valve for garage floor drains. 19

20 While residential sprinklers are not required by code, this chapter provides the installation requirements for fire sprinklers should an owner or builder choose to install. 20

21 If sprinklers are to be installed in all or part of a dwelling, garage or accessory building, the sprinkler system shall be installed per any of the four methods indicated. 21

22 Chapter 34 contains the electrical provisions for the dwellings, garages and any accessory structures. 22

23 This chapter incorporates the 2011 Edition of the National Electrical Code (NEC) NFPA 70 to regulate the installation testing and operation of electrical systems. The RCO contains some specific modifications to the 2011 NEC. 23

24 This electrical code is modified to permit a single receptacle in a garage specifically for a garage door opener to not have to be ground-fault circuitinterrupter protected. 24

25 Similar to the previous item, the basement is now permitted to have a single receptacle for the sump pump that does not have to be ground-fault circuitinterrupter protected IF there is a GFCI-protected duplex receptacle within 6 feet of the sump pump. A receptacle that is not GFCI protected is also permitted for an alarm system. 25

26 GFCI protection has been extended to all receptacles that are within 6 feet of the outside edge of any sinks. 26

27 Arc-fault protection for branch circuits has been extended to all habitable spaces, except kitchens, but including hallways, closets and similar spaces. And that protection must be from a combination-type arc-fault current interrupter for the entire branch circuit. 27

28 While GFCI protection has been extended to the garages and unfinished grade-level areas of unfinished accessory buildings used for storage or work areas, please note that Arc-Fault Circuit Interrupter protection has been extended only to habitable spaces and omits kitchens, bathrooms and toilet rooms, laundry rooms and garages. 28

29 A receptacle outlet is now required for each balcony, deck, or porch. 29

30 Receptacles are now required for foyers greater than 60sf. 30

31 Ground rods must be listed or meet a minimum diameter of 5/8. 31

32 Ceiling mounted fans require a box listed to support a ceiling suspended fixture. 32

33 All light switches shall contain a separate ground. 33

34 Electrical non-locking type receptacles in new dwelling construction must be installed with tamper-resistant receptacles. 34

35 GFCI protections for electrically heated floors has been added for kitchens. 35
