Notes: * NA – do not include vent terminal into total vent length calculations.
** These sections have plain male end and beaded female end. See Figure 19 for details.
*** These sections have beaded male end and beaded female end. See Figure 20 for details.
1. Vertical terminal can be used with either of the roof ashings listed beneath it.
2. Sloped roof ashing suitable for roof angles between 25° and 45°.
3. Used at base of vertical run inside unused masonry chimney.
Table 15: Concentric Vent Components
Follow manufacturer’s instructions to
attach terminal to vent system.
ii. Combustion Air Termination
• Install vertical combustion air terminal.
Vertical combustion air terminal consists
of an 180° bend (comprised of two (2) 90°
elbows) as shown in Figure 12.
• Install rodent screen (not supplied) in the
combustion air terminal. Use a screen
having 1/2” (2 x 2) or larger mesh.
E. Concentric Polypropylene Venting
1. Vent Length Restrictions
a. Vent length restrictions are based on equivalent
length of vent pipe i.e. total length of straight pipe
plus equivalent length of ttings. See Table 14
for specied vent length details. Do not exceed
maximum vent length. Table 15 lists available
concentric vent components and includes equivalent
vent length for ttings.
b. The vent termination location is restricted as per
‘General Guidelines’, Paragraph A, 5 (refer to
Figure 4).
2.
Field Installation of Boiler Concentric Vent
Collar
a. Locate and remove six mounting screws from the
Miscellaneous Parts Carton.
b. Position the Collar onto jacket combination rear/
bottom panel and insert collar inner stainless steel
vent pipe into the heat exchanger vent outlet.
c. Align collar plate clearance holes with rear/bottom
panel engagement holes; then secure the collar to
rear/bottom panel with six mounting screws. See
Figure 18.
