FIREPLACE DRAFT TEST

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 MHS, Inc. 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 peri- odically clean and inspect the logs per the cleaning and servicing.

WARNING

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 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 professionally inspected to determine if your firebox/chimney is venting properly.
