Cold Climate Insulation - ORTAL 40 Series Installation And Operation Manual

•
Block as few ports as possible, and no more than 30% of total ports. Do NOT block ports that are next
to one another. This will cause delayed ignition.
•
When combining both logs and glass, it is recommended to place the logs (and coins if needed) first,
and then to spread the glass according to the instructions given above.
Seal all cracks around your fireplace with noncombustible material wherever cold air could enter the room. It is
especially important to insulate outside chase cavity between fastenings, and under the floor on which the fireplace
rests if the floor is above ground level. Gas line holes and other openings should be caulked or stuffed with un-faced
fiberglass insulation.
If the fireplace is being installed on a cement slab, a sheet of plywood or other raised platform can be placed
underneath to prevent cold transfer to the fireplace and into the room. It also helps to sheetrock inside surfaces and
tape and caulk fire stops for maximum air tightness.
