HEATER CLEARANCES — General Requirements
INDOOR INSTALLATION (U.S.) OR OUTDOOR SHELTER (CANADA)
The following clearances must be maintained from combustible surfaces:
TOP .............................. 6 in. (15 cm)
ALL SIDES .................. 6 in. (15 cm)
VENT............................ 6 in. (15 cm)
Note: The heater is design certified by CSA International for installation
on combustible flooring. For installation on carpeting, the heater must be
mounted on a metal or wood panel that extends at least three inches
(10cm) beyond the base of the heater. If the heater is installed in a
closet or alcove, the entire floor shall be covered by the panel. On an
outdoor shelter installation, the exhaust discharges into a vent pipe.
Orient the heater so that the vent pipe does not interfere with adjustment
of the operating controls. The operating control panel, located on the top
of the jacket, can be rotated for convenient access to the control panel.
OUTSIDE VENT COVER REMOVAL
The heater is supplied from the factory with a built-in stackless outside
vent for outdoor installation. Remove the outside vent cover for outdoor
shelter installation.
