Fireplace Draft Test - Monessen Hearth VWF18 Installation And Operating Instructions Manual

FIREPLACE DRAFT TEST

IMPORTANT: Fireplace Draft Test During Initial Installation
It is critical to verify that your chimney is drafting properly because the fi replace and gas logs function as a system.
Although Monessen Hearth systems 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
fi replace.
FIREPLACE DRAFT TEST METHOD
To determine if your fi replace 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 fi replace opening. If the fl ame or smoke is not pulled into the
fi replace, then the fi replace 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 fi replace system should
be professionally inspected to determine if your fi rebox/chimney is venting properly.
