Fireplace Draft Test - Vermont Castings VWF18 Installation And Operating Instructions Manual

VWF Series Vented Gas Log Set
IMPoRTAnT: Fireplace Draft Test During Initial Installation
It is critical to verify that your chimney is drafting properly because the fireplace and gas logs
function as a system.
Although Vermont Castings Group goes to great lengths to design vented gas log sets
that minimize sooting, all vented log sets will soot over time. Sooting normally appears
as areas of black powder-like substance on the logs. It is important to periodically clean
and inspect the logs per the cleaning and servicing.
Fireplace systems that do not draft properly can increase the amount of
soot produced by normal operation of the log set and, in extreme cases,
can cause soot to be deposited within the room. This effect can be a sign of
a blocked chimney, a faulty vent system or the result of negative pressure
within the home. The dealer should be able to diagnose if a problem exists
and be able to provide a solution to improve the venting of the fireplace.
FIREPLACE DRAFT TEST METHOD
To determine if your fireplace is drafting properly, turn the log set on. After log set has been
burning for about 10 minutes, place a match or smoke stick along the top and sides of the fire-
place opening. If the flame or smoke is not pulled into the fireplace, then the fireplace is not
venting properly. At this point, the damper stop should be adjusted so that the damper open-
ing is increased. If the problem remains after the open area of the damper is increased, then
the fireplace system should be professionally inspected to determine if your firebox/chimney is
venting properly.
