UVC / UVS Vent-Free Heaters
20000135
Safety Devices
Adequate combustion and ventilation air must be pro-
vided. The flow of combustion and ventilation air MUST
NOT be obstructed.
Provide adequate clearances around the air opening
into the combustion chamber; and adequate accessibili-
ty clearance for servicing and proper operation. NEVER
obstruct the front opening of the heater or cover the top
and bottom louvres (grilles).
These heaters are equipped with a pilot system fea-
turing an Oxygen Depletion Sensor (O.D.S.) shut-off
device. All unvented heaters are required to have this
system. The O.D.S. pilot will shut down the heater
when there is not enough fresh air available.
Report any parts damaged in shipment to your dealer.

IMPORTANT:
Please Review the Following Carefully
It is normal for fireplaces fabricated of steel to give off some
expansion and/or contraction noises during the start up or cool
down cycle. Similar noises are found with your furnace heat
exchanger or car engine.
It is not unusual for your gas fireplace to give off some odor the
first time it is burned. This is due to the curing of the paint and
any undetected oil from the manufacturing process.
Please ensure that your room is well ventilated - open all
windows.
It is recommended that you burn your Vermont Castings Majestic
Products fireplace for a least six (6) hours the first time you use
it. If optional fan kit has been installed, place fan in the "OFF"
position during this time.
