1. Under certain conditions it is recommended that the Lincoln SCR be connected to an outside

source of combustion air to improve performance. Flexible metal hose, or rigid metal pipe,

(conduit), must be connected around (NOT INSIDE) the combustion air inlet tube. Be careful not

to pinch or bend the outside air pipe with too small a radius which may be terminated flush with

the outside wall but should be protected from wind and weather by a hood. Note: The outside air

pipe must terminate above the maximum snow line.

2. Outside air may be drawn from a semi-enclosed attic or crawl space or any semi-enclosed space.

Take care not to draw cold air past water pipes that may freeze.

3. Increase the outside air pipe diameter to 3" for runs over ten (10) feet and elevation over 4,000 feet.

Note: Long runs should be avoided.

4. Terminate the outside air pipe below the exhaust vent outlet.

5. An open mesh screen should be placed over the outside air pipe opening to prevent birds or rodents

from nesting in the opening. Use an elbow or shield to prevent prevailing winds from blowing

directly into the outside air intake pipe. NOTE: Mesh screen should be no smaller than one-fourth

inch (1/4") by one-fourth inch (1/4").

WARNING: OUTSIDE COMBUSTION AIR IS REQUIRED FOR ALL MOBILE HOME INSTALLATIONS!
