Figure 7 - Clearances for Combustible Mantels
• Install horizontal venting with a 1/4" rise | |
| for every 12" of run toward the termination. |
• | You may paint the vent terminal with |
| 450ºF (232ºC) |
| ordinate with the exterior finish. |
• | There must not be any obstruction such |
as bushes, garden sheds, fences, decks, or utility buildings within 24" from the front of the termination cap.
•Do not locate termination cap where ex- cessive snow or ice build up may occur. Be sure to clear vent termination area af- ter snow falls to prevent accidental block- age of venting system. When using snow blowers, do not direct snow towards vent termination area.
Location of Vent Termination
When locating vent termination, it is impor- tant to observe the minimum clearances shown in Figure 8, page 6. You will avoid extra framing by positioning your fireplace against an already existing framing mem- ber. The sides of the fireplace may be posi- tioned directly against combustible walls.
*Check with local codes or with the current CAN/CGA B149[.1 or .2] Installation Codes for Canada or the USA Installations follow the current National Fuel Gas Code, ANS Z223.1, also known as NFPA 54.
