HOW TO LOCATE CHIMNEY EXIT AND INSTALL
Residential and Mobile Home Installation
F. Vertical Wall Exit using (6" DVL Close Clearance Pipe and Elbow and any Listed
2100° UL HT chimney and Listed 2100° UL HT T-Box assembly).
With optional close clearance shield and pipe shield NOTE: For installation of optional
close clearance shields and pipe shield (See Page 35).
NOTE: For minimum clearances (See Page 28, Figure 25).
If pedestal kit is being used and out side air is required (See Pages 15-16).
1. Mark plumb line on wall directly behind center of heater.
(See Page 28, Figure 26).
NOTE: When using DVL Close Clearance Pipe, maintain manufacturer's minimum
clearances between pipe and ceiling.
2. Place vertical portion of heater pipe and elbow in position and project a point onto plumb
line level with center of elbow.
3. Measure up so there will be at least 1/4" rise per foot of horizontal connector pipe,
maintaining clearances to ceiling as noted in (Page 28, Figure 26). This will give you
center of hole for chimney penetration.
4. After locating center of the penetration, install the tee-box and chimney, per chimney
manufacturer's specifications.
5. Connect the DVL close clearance pipe to tee-box, per manufacturer's instructions.
DVL close clearance pipe is to be connected with (3) sheet metal screws or rivets to
connector collar on heater.(See Page 28, Figure 26).
6. NOTE: If your local code requires outside air for residential installation, refer to pages
15-16 for outside air installation.
