IMPORTANT NOTES:

•Minimize the use of elbows (30°, 45° or 90°) - Offsets in the venting system are very restrictive and will inhibit the draft (i.e. You will lose approximately 5 feet of effective draft for every 90 degrees of direction change). This appliance re- quires 12 to 15 feet of effective draft for optimum perform- ance (see Draft Requirements on page 11).

•First section of pipe must be vertical - Use as much straight vertical pipe directly above the appliance as possible be- fore using an elbow (a 2’ to 3’ initial vertical rise is sug- gested).
