GENERAL VENTING INFORMATION

GENERAL VENTING INFORMATION

Your fireplace is approved to be vented either through the side wall, or vertically through the roof.

Only venting components specifically approved and labelled for this fireplace may be used.

Minimum clearances between vent pipes and com- bustible materials is one (1") inch (25 mm).

Venting terminals shall not be recessed into a wall or siding.

Horizontal venting must be installed on a level plane without any incline or decline.

There must not be any obstruction such as bushes, garden sheds, fences, decks or utility buildings within 24" from the front of the termination hood.

Do not locate termination hood where excessive snow or ice build up may occur. Be sure to check vent termination area after snow falls, and clear to prevent accidental blockage of venting system. When using snow blowers, make sure snow is not directed towards vent termination area.

Location of Vent Termination

It is imperative that the vent termination be located observing the minimum clearances as shown on this page.

*Check with local codes or in absence of same with CAN/CGA

B149 (.1 or .2) Installation Codes (1991) for Canada or for U.S.A. Installations follow the current National Fuel Gas Code, ANSI Z223.1.
