cifically approved for this fireplace.

• Minimum clearance between vent pipes

 

and combustible materials is 1" (25 mm),

 

except where stated otherwise.

wall or siding.

• 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) heat-resistant paint to co-

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 exces-

sive snow or ice build up may occur. Be sure

to clear vent termination area after snow falls

to prevent accidental blockage 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.
