ANNUAL FIREPLACE MAINTENANCE

 

 

Your  fireplace  and  chimney  require  seasonal  and 

monthly tune-

ups”. Like any piece of well-built  equipment, the 

Mason-Lite 

Fireplace 

and 

chimney 

needs 

routine 

maintenance.

 

 

The manufacturer  recommends  that  inspection  of  the 

fi replace and chimney take place on a monthly basis  during the 
heating season.

 

 

Start at the top, looking for 

birds’ nests, leaves or any 

other obstructions. Also check the spark arrestor, for creosote 
or soot build-up. Twice a year, you will want to clean the firebox 
and chimney yourself or hire a professional chimney sweep to 
do the job for you. If you elect to do it yourself, use a plastic, 
wood or steel brush for the inside of the chimney.

 

 

For  the  spark  arrestor,  scrub  with  a  wire  brush.  To 

dismantle  the  chimney  cap  for  cleaning  of  the  flue,  unscrew 
the four screws that hold it in place. For cleaning access from 
below, open the damper in the firebox. It is best to use a flexible 
handle chimney cleaning brush made especially for the job.

 

 

If  your  fireplace  system  has  any  offset  chimney 

sections,  start  cleaning  with  the  flexible  brush  from  the  top  of 
the  section  downward  to  the  elbow.  Then  clean  from  the  firebox 
up  to  the  offset/return  section.

 

 

Be sure that you have covered the floor of the fireplace 

and out to the hearth with a damp sheet that has been taped 
securely  in  place.  When  all  the  soot  has  settled,  remove  the 
sheet and vacuum up 

– don’t sweep the excess soot.

 

 

Good  old-fashioned 

“elbow  grease”  is  enough  to 

remove  the  extraneous  matter  from  the  inside  of  the  firebox 
and chimney. Never use any chemical cleaners as their residue 
could introduce a fire hazard after the task is completed.

 

 

Outside  Inspection 

–  During  your  once  a  month 

inspection  of the  firebox and  chimney, make it  a point  to also 
check the outside of the chimney, the metal flashing and weather 
seals that surround it. If you find any cracks or openings around 
screws or nails, seal them to avoid any roof or chimney chase 
leaks.

 

SURFACE CRACKS

 

The  MASON-LITE  FIREPLACES  are  manufactured 

using high quality materials. During the drying process, surface 
cracking  may  occur. These  small  cracks  (under 

1/16” will not 

effect the fireplace safety or performance). During the assembly 
process, fill surface cracks with thin-set mortar and brush when 
drying for a smooth surface finish.

 

 

Removal of Creosote and Soot Formation 

– Creosote 

vapors are known to form in the relatively cool chimney flues of 
slow burning fires, hence, creosote residue collects on the flue 
lining. Because of soot and creosote build-up, it is recommended 
that the fireplace and chimney cleaning be done twice a year. In 
colder climates, cleaning should be done more often.

 

 

Always  allow  the  fireplace  to  completely  cool  before 

you work on it, which means, of course, shutting off all gas and 
electrical connections, also.

 

 

Be certain that you use only solid fuel in your fi replace. 

You may use a natural or LP gas log lighter as a method to start 
your wood fire.

 

 

The  flue  damper  must  be  in  the  OPEN  position 

whenever  there  is  heat  in  the  fireplace.
