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 24 & 25).

venting style.

In either case, the fireplace may be connected to

the chimney/vent using a 4” (10 cm) single wall vent

connector.

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.

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.
