Initial Installation

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 46 & 47).

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 connected to an approved 4” (10 cm) diameter flue liner running the full height of the chimney. In many jurisdictions this flue liner may be mandatory.

If 4” (10 cm) single wall vent is used, a minimum of 6” (15 cm) must be maintained between the vent connector and any combustibles.

If 4” (10 cm) “B-vent” is used a minimum of 1” (25

mm) must be maintained between the vent connector and any combustibles.

CAUTION: A minimum vent height of 12’ (3.6 m) from the floor is required to effectively vent this fireplace.

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.

4.After a minimum of 10 minutes operation, test the chimney draft with a smoke match at the top row of the pattern to confirm that there is adequate draft or ‘pull’ at the openings around the body of the Drafthood Adaptor, as shown in Figure 48.

Check vent draft at the top row of opening.
