405 data substantiating the adjustments. A record of such action together with the substantiating
406 data 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

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:
901 Pg = Ground snow load at a given elevation (psf);
902 Po = Base ground snow load (psf) from Table No. R301.2(5a);
903 S = Change in ground snow load with elevation (psf/100 ft.) From Table No. R301.2(5a);
904 A = Elevation above sea level at the site (ft./1,000);
905 Ao = Base ground snow elevation from Table R301.2(5a) (ft./1,000).
906 The building official may round the roof snow load to the nearest 5 psf. The ground snow

907 load, Pg, may be adjusted by the building official when a licensed engineer or architect submits
908 data substantiating the adjustments. A record of such action together with the substantiating
909 data 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
911 R301.2(5b), provided the site is no more than 100 ft. higher than the listed elevation.
912 Where the minimum roof live load in accordance with Table R301.6 is greater than the design
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."

1805 place to avoid displacement. Every furnace and water heater shall be accessible for servicing,
1806 for replacement, or both as required by MHCSS 3280.709(a).
1807 (iii) Installation. Furnaces and water heaters shall be installed to provide complete
1808 separation of the combustion system from the interior atmosphere of the manufactured home,
1809 as required by MHCSS.
1810 (A) Separation. The required separation may be achieved by the installation of a
1811 direct-vent system (sealed combustion system) furnace or water heater or the installation of a
1812 furnace and water heater venting and combustion systems from the interior atmosphere of the
1813 home. There shall be no doors, grills, removable access panels, or other openings into the
1814 enclosure from the inside of the manufactured home. All openings for ducts, piping, wiring,
1815 etc., shall be sealed.
