General Venting Information, A. Installations

Initial Installation

GENERAL VENTING INFORMATION:

Canadian Installations

The venting system must be installed in accordance with the current CSA B149 installation code and/or local codes having jurisdiction.

U.S.A. Installations

The venting system must be installed in accordance with the current National Fuel Gas Code, ANSI Z223.1, and/or local codes having jurisdiction.

The minimum clearance to combustibles is 6” (150 mm) when using single wall venting and 1” (25 mm) when using “B-vent” venting.

We strongly recommend installing an approved chimney liner in an existing brick chimney. This will maximize the potential draft of the chimney and lessen the effects of slow chimney start-up.

VENTING OF A FIREPLACE FITTED WITH THE DRAFTHOOD ADAPTOR:

Note: Please refer to the chimney manufacturer’s installation instructions prior to commencing the installation.

This unit may be vented to an existing masonry chimney, or where no masonry chimney is available, an approved “B-vent” chimney, or any other approved constructed chimney/vent system (see Figure 40 & 41).

		In either case, the fireplace may be connected to
		the chimney/vent using a 4” (10 cm) single wall vent
		connector.
		When an existing masonry chimney
	��	is utilized for the venting, we
	��	recommend the vent connector be

	SPILLAGE TEST:
	A spillage test must be performed prior to leaving the installed fireplace
	with the customer. Perform this test in the following manner:
	1. Close all windows and doors in the room.
	2. Start all exhaust fans in the house and the furnace blower.
	3. Light the fireplace and set to maximum flame adjustment.
