HOW TO LOCATE CHIMNEY EXIT AND INSTALL
Residential and Mobile Home Installation
D. 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 22).
NOTE: For minimum clearances (See Page 13, Figure 8).
For Required Out Side Air in Mobile Homes (See Page 14).
1. Mark the plumb line on the wall directly behind the center of the heater.
(See Page 13, Figure 9).
NOTE: When using DVL Close Clearance Pipe , “maintain manufacturer’s minimum
clearances” between pipe and ceiling.
2. Place the vertical portion of the heater pipe and the elbow in position and project a
point onto the plumb line level with the center of the elbow.
3. Measure up so there will be at least 1/4" rise per foot of horizontal connector pipe, main-
taining clearances to the ceiling as noted in (Page 13, Figure 9). This will give you the
center of the hole for the chimney penetration.
4. After locating the center of the penetration, install the tee-box and chimney as per the
chimney manufacturer's specifications.
5. Connect the DVL close clearance pipe to the 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 13, Figure 9).
