Starting a Fire and Basic Operation

  Before starting a fire in your fireplace, open the damper to 

its’ fully open position. Crumple some paper and place it on the 

log grate. Use some soft, dry wood as kindling and put it on top 

of the paper. Place some small logs or split logs atop the paper 

and kindling.

  Finish off the fuel load with a couple of hardwood logs or 

split logs – oak or hickory. Check to see that you’re stacking the 

logs so that they will fall inside the grate as they burn.

  To get the most out of your wood, it is recommended that 

you let it set and completely dry out for nine months to a year.

  When you are satisfied with the arrangement of your wood 

load, light the paper which in turn will ignite the kindling, then 

the softer wood and finally, the harder wood logs. As the fire 

burns, you can carefully lay additional logs on the flame, but 

make sure you place them gently without forcing them into the 

opening.

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 

fireplace 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.

 

Never use any chemical cleaners to clean the insude 

of your flue 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 fireplace. 

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.
