Firebrick Liner Installation
It is required that the interior sides, rear and bottom be lined
with minimum 1-1/8” thick firebrick. Mason-Lite Pre-fabricated
fire brick liner walls can make the installation easier.
All required through-wall accesses (gas and electrical
line feeds and combustion air supply access holes) should be
drilled before the required fire brick lining is installed.
Modular Firebrick Lining
If using our Mason-Lite Firebrick Liners, simply use an extra
bucket of mortar. Install Hearth Liner first, rear next and sides
last. Consider if brackets for grates will be required, also if
pre-drilling is required for gas lines, electrical or if the outside
combustion air kit is to be installed.

Initial Fireplace Operation
Follow the gas appliance manufacturers’ requirements
for lighting and operating your vent free log. When first operating
the fireplace, open a window in the room to allow smells created
from the heater and fireplace curing.
We suggest operating the heater for several 30 minute
intervals allowing the fireplace to cool for an hour in between.
This will allow any moisture in the brick and fireplace to
escape.
Keep in mind that it may require several operations
to completely remove any smell from the operation of a vent-
free heater and fireplace. If this condition continues, contact
your gas appliance dealer to inspect the gas heater for proper
operation.
