The furnace may be vented vertically through the roof. The outlet/inlet of the vent and air intake terminations shall be a minimum of 12 inches above highest anticipated snow level. The vent outlet must be installed a minimum of 12 in. above the air intake inlet. The combustion air intake shall be installed upwind of the vent outlet when exposed to prevailing winds.The exhaust vent and combustion air intake can be a minimum of 3 in. and a max. of 24 in. apart see Figures 11 & 12.
