             403      The building official may round the roof snow load to the nearest 5 psf. The ground snow load,
             404      Pg, may be adjusted by the building official when a licensed engineer or architect submits data
             405      substantiating the adjustments. A record of such action together with the substantiating data
             406      shall be provided to the division for a permanent record.
             407      The building official may also directly adopt roof snow loads in accordance with Table

             897      Snow Loads. The ground snow load, Pg, to be used in the determination of design snow loads
             898      for buildings and other structures shall be determined by using the following formula: Pg = (Po2
             899      + S2(A-Ao)2)0.5 for A greater than Ao, and Pg = Po for A less than or equal to Ao.
             900      WHERE:

             905      Ao = Base ground snow elevation from Table R301.2(5a) (ft./1000).
             906      The building official may round the roof snow load to the nearest 5 psf. The ground snow load,
             907      Pg, may be adjusted by the building official when a licensed engineer or architect submits data
             908      substantiating the adjustments. A record of such action together with the substantiating data
             909      shall be provided to the division for a permanent record.
             910      The building official may also directly adopt roof snow loads in accordance with Table

             913      roof snow load, such roof live load shall be used for design, however, it shall not be reduced to
             914      a load lower than the design roof snow load. Drifting need not be considered for roof snow
             915      loads less than 20 psf."

             1766          (B) Air-intake assembly and combustion-air inlet. An air-intake assembly shall be
             1767      installed in accordance with the terms of listings and the manufacturer's instruction. A
             1768      combustion air inlet shall conduct the air directly into the fire chamber and shall be designed to
             1769      prevent material from the hearth from dropping on the area beneath the manufactured home.
             1770          (C) Hearth. The hearth extension shall be of noncombustible material that is a
             1771      minimum of 3/8-inch thick and shall extend a minimum of 16 inches in front and eight inches
             1772      beyond each side of the fireplace/fireplace stove opening. The hearth shall also extend over the


             1773      entire surface beneath a fireplace stove and beneath an elevated and overhanging fireplace.
             1774          (e) Related to electrical wiring systems:
             1775          (i) Testing. All electrical systems shall be tested for continuity in accordance with
             1776      MHCSS 3280.810, to ensure that metallic parts are properly bonded; tested for operation, to
             1777      demonstrate that all equipment is connected and in working order; and given a polarity check,
             1778      to determine that connections are proper.
             1779          (ii) 5.2 Protection. The electrical system shall be properly protected for the required
             1780      amperage load. If the unit wiring employs aluminum conductors, all receptacles and switches
             1781      rated at 20 amperes or less that are directly connected to the aluminum conductors shall be
             1782      marked CO/ALA. Exterior receptacles, other than heat tape receptacles, shall be of the
             1783      ground-fault circuit interrupter (GFI) type. Conductors of dissimilar metals (copper/aluminum
             1784      or copper-clad aluminum) must be connected in accordance with NEC, Section 110-14.
             1785          (f) Related to replacement furnaces and water heaters:
             1786          (i) Listing. Replacement furnaces or water heaters shall be listed for use in a

             1791      for replacement, or both as required by MHCSS 3280.709(a).
             1792          (iii) Installation. Furnaces and water heaters shall be installed to provide complete
             1793      separation of the combustion system from the interior atmosphere of the manufactured home,
             1794      as required by MHCSS.
             1795          (A) Separation. The required separation may be achieved by the installation of a
             1796      direct-vent system (sealed combustion system) furnace or water heater or the installation of a
             1797      furnace and water heater venting and combustion systems from the interior atmosphere of the
             1798      home. There shall be no doors, grills, removable access panels, or other openings into the
             1799      enclosure from the inside of the manufactured home. All openings for ducts, piping, wiring,
             1800      etc., shall be sealed.
             1801          (B) Water heater. The floor area in the area of the water heater shall be free from
             1802      damage from moisture to ensure that the floor will support the weight of the water heater.
