CAUTION: This heater creates warm air currents.
These currents move heat to wall surfaces next to
heater. Installing heater next to vinyl or cloth wall
coverings or operating heater where impurities (such
as but not limited to, tobacco smoke, aromatic candles,
cleaning fluids, oil or kerosene lamps, etc.) in the air
exist, may discolor walls or cause odors.
IMPORTANT:
Vent-free heaters add moisture to the air. Although
this is beneficial, installing heater in rooms without enough venti-
lation air may cause mildew to form from too much moisture. See
Air for Combustion and Ventilation, pages 4 through 6. If high
humidity is experienced, a dehumidifier may be used to help lower
the water vapor content in the air.
CAUTION: If you install the heater in a home garage
• heater pilot and burner must be at least 18 inches
(46 cm) above floor
• locate heater where moving vehicle will not hit it
For convenience and efficiency, install heater
• where there is easy access for operation, inspection, and service
• in coldest part of room
For 20,000 Btu/hr (5.9 kW) models, an optional fan kit is available
from your dealer. See Accessories, page 29. If planning to use fan,
locate heater near a grounded electrical outlet. Outlet must be
grounded in accordance with local codes, with the current Canadian
Electrical Code Part 1 CSA C22.1.
