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 31 & 32).
In either case, the replace 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 ue liner
running the full height of the chimney. In
many jurisdictions this ue 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 oor is required to
effectively vent this replace.
SPILLAGE TEST:
A spillage test must be performed prior to leaving the installed replace 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 replace and set to maximum ame 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 conrm that there is adequate draft or ‘pull’ at the openings around the body of the Drafthood Adaptor,
as shown in Figure 33.
