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  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. 

W

ARNING

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.
