VWFST 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 sub-
stance on the logs. It is important to periodically clean
and inspect the logs per the cleaning and servicing.
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 fireplace 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 opening is increased. If
the problem remains after the open area of the damper
is increased, then the fireplace system should be profes-
sionally inspected to determine if your firebox/chimney is
venting properly.

FIREPLACE DRAFT TEST
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.
