966     data substantiating the adjustments.
967     Where the minimum roof live load in accordance with Section [1607.11] 1607.12 is greater
968     than the design roof snow load, such roof live load shall be used for design, however, it shall

2495     fireplace/fireplace stove and equipped with, in accordance with the listing, a termination device
2496     and spark arrester, shall be required. The chimney shall extend at least three feet above the part
2497     of the roof through which it passes and at least two feet above the highest elevation of any part
2498     of the manufactured home that is within 10 feet of the chimney.]
2499          [(ii) Air-intake assembly and combustion-air inlet. An air-intake assembly shall be

2500     installed in accordance with the terms of listings and the manufacturer's instruction. A
2501     combustion-air inlet shall conduct the air directly into the fire chamber and shall be designed to
2502     prevent material from the hearth from dropping on the area beneath the manufactured home.]
2503          [(iii) Hearth. The hearth extension shall be of noncombustible material that is a
2504     minimum of 3/8-inch thick and shall extend a minimum of 16 inches in front and eight inches
2505     beyond each side of the fireplace/fireplace stove opening. The hearth shall also extend over the
2506     entire surface beneath a fireplace stove and beneath an elevated and overhanging fireplace.]

2508          [(a) Testing. All electrical systems shall be tested for continuity in accordance with
2509     MHCSS 3280.810, to ensure that metallic parts are properly bonded; tested for operation, to
2510     demonstrate that all equipment is connected and in working order; and given a polarity check,
2511     to determine that connections are proper.]
2512          [(b) 5.2 Protection. The electrical system shall be properly protected for the required
2513     amperage load. If the unit wiring employs aluminum conductors, all receptacles and switches
2514     rated at 20 amperes or less that are directly connected to the aluminum conductors shall be
2515     marked CO/ALA. Exterior receptacles, other than heat tape receptacles, shall be of the
2516     ground-fault circuit interrupter (GFI) type. Conductors of dissimilar metals (copper/aluminum
2517     or copper-clad aluminum) must be connected in accordance with NEC, Section 110-14.]
2518          [(6) Related to replacement furnaces and water heaters:]
2519          [(a) Listing. Replacement furnaces or water heaters shall be listed for use in a
2520     manufactured home. Vents, roof jacks, and chimneys necessary for the installation shall be
2521     listed for use with the furnace or water heater.]

2526     separation of the combustion system from the interior atmosphere of the manufactured home,
2527     as required by MHCSS.]
2528          [(i) Separation. The required separation may be achieved by the installation of a
2529     direct-vent system (sealed combustion system) furnace or water heater or the installation of a
2530     furnace and water heater venting and combustion systems from the interior atmosphere of the

2531     home. There shall be no doors, grills, removable access panels, or other openings into the
2532     enclosure from the inside of the manufactured home. All openings for ducts, piping, wiring,
2533     etc., shall be sealed.]
2534          [(ii) Water heater. The floor area in the area of the water heater shall be free from
2535     damage from moisture to ensure that the floor will support the weight of the water heater.]
