A. Positioning
Maintain clearance around and above unit to provide mini- mum distance from combustible materials, proper airflow, and service access. See Fig. 1A and 1B Notes.
Do not install unit in an indoor location. Do not locate unit air inlets near exhaust vents or other sources of contami- nated air.
Be sure that unit is installed so that snow will not block the combustion intake or flue outlet.
Unit may be installed directly on wood flooring or on Class A, B, or C
Although unit is weatherproof, guard against water from higher level runoff and overhangs.
Position unit on roof curb so that the following clearances are maintained:
Locate mechanical draft system flue assembly at least 48 in. from an adjacent building or combustible material. When unit is located adjacent to public walkways, flue assembly must be at least 7 ft above grade.
Flue vent discharge must have a minimum horizontal clear- ance of 48 in. from electric and gas meters, gas regulators, and gas relief equipment.
Flue gas can deteriorate building materials. Orient unit so that flue gas will not affect building materials.
