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.
