Using gas:
 
is it necessary to clean chimneys where it is a gas burning appliance?
 
Natural gas is a clean burning fuel. The fumes produced contain high levels of water vapor leading to more condensation. The vapors also contain chlorides which results in the more corrosive conditions for the chimney flues. This means the chimney flue can either plug up completely or deteriorate quicker than normal.
 
If it is a terra cotta clay flue then all that is required is an inspection to make sure that it is clear of debris. Burning gas produces carbon monoxide and water. Water vapor causes masonry, especially terra cotta to flake causing pieces to fall into the flue, adding debris in the flue and compromising the chimney structure. Gas appliances should always be vented using class b venting or other applicable gas vents suitable for your appliance. Also your chimney may contain squirrel nests, bird nests etc. all chimneys should have suitable caps. If your masonry chimney is free of debris do not have it cleaned as this will only cause more chipping of the weakened flue tiles.
 
The acids that can be released by a gas furnace into a masonry flue cannot be cleaned out. They only pose a problem if the flue gas cools off enough to condense water onto the liner. Higher efficient furnaces with cooler stack temps, will need a class b type liner installed in the masonry flue for correct operation. The lower stack temp will not draw in a larger stack correctly and will cause flue gas condensation and chlorides, and expedited deterioration of the chimney.
