HEATER CLEARANCES — General Requirements
INDOOR INSTALLATION (U.S.) OR OUTDOOR SHELTER (CANADA)
The following clearances must be maintained from combustible surfaces:
TOP .................................. 3 ft. (1 m)
EXHAUST SIDE .......... 6 in. (15 cm)
HEADER SIDE ............ 6 in. (15 cm)
DOOR PANELS† ........ 6 in. (15 cm)
Note (†) For service access it is advisable to allow for sufficient clearance
on at least one door panel. 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 control panel located on the top panel can be rotated
to any of the three sides of the heater for easy access. However, the
control panel must not be located on the side where the vent is located.
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.
