Maintenance and Service
Maintenance
Once installed and operating properly, the Mason-lite
®
gas fireplace requires very little maintenance. You should
inspect the fireplace, chimney, burner and control annually
for the following:
1. Excessive Sooting -
Some sooting of the logs is
normal and adds to the natural appearance of burned
wood. If soot accumulates, you may brush the soot off
with a stiff brush. Logs may also be cleaned by allowing
them to heat up, then spraying them with water where
soot has accumulated.
2. Debris around the control -
Inspect the control and
pilot to be sure it is free of any dirt or debris.
3. Insects and burner blockage -
Check the burner
ports and the air-mixer, if present, to make sure
they are free from debris. Blocked burner ports and
orifices may result in poor flame distribution or flame at
air-mixer (if equipped). Reference SOLUTION, to
symptoms 2-4, of

Service
It is recommended that a qualified professional service
technician be called to service the gas fireplace and its
venting system at least annually or should service be
required. More frequent cleaning may be required due to
excessive lint from carpeting, bedding material, etcetera.
It is imperative that control compartments, burners and
circulating air passageways of the appliance be kept clean.
The
Troubleshooting
section of these instructions serves
as a guide for ensuring optimum performance of the gas
fireplace.
Flame Appearance
The flames should be blue at the base and a combination of
blue/yellow at the body and tips.
