HOW TO LOCATE CHIMNEY EXIT AND INSTALL
Residential Installation
B. Vertical Wall Exit using (6" Single Wall minimum 24 ga. blued or black pipe with el-
bow and any Listed 2100° UL HT chimney and Listed 2100° UL HT. T-Box assembly)

NOTE: For minimum clearances (See Page 9, Figure 4).
1. Mark the plumb line on the wall directly behind the center of the heater.

“ maintain 18" 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,
maintaining clearances to the ceiling as noted in (Page 9,Figure 5). This will give you
the center of the hole for the chimney penetration.

chimney manufacturer's specifications.
5. Connect the chimney collar to the tee-box using 6" Single Wall minimum 24 ga. blued
or black pipe. (DO NOT USE GALVANIZED PIPE). Connect each section so the
crimped end faces downward and secure each section to each other using three (3)
sheet metal screws or rivets. Single wall pipe is to be connected with three (3) sheet
metal screws rivets to connector collar on heater.(See Page 9, Figure 5).
