HEATER CLEARANCES — General Requirements
INDOOR INSTALLATION AND OUTDOOR SHELTER
The following clearances must be maintained from the nearest walls: (See Figure 19, 20 & 21)
TOP ................................... 15 cm (6 in)
EXHAUST SIDE ............... 15 cm (6 in.)
Note (*) For service access it is advisable to allow for sufficient clearance on at least one door panel. The heater is
designed for installation on combustible flooring. For installation on carpeting, the heater must be mounted on a metal or
wood panel that extends at least 10 cm (4 in) beyond the base of the heater. Note: Wall sensitive to heat
(for example wood), must be protected by a suitable insulation. 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.
(*) For service access, it is advisable to allow for
sufficient clearance on at least one door panel.
