and draperies.
The surface of the Heater Is hot when it is in use.
Young children should be watched carefully when
they are in the same room when the Heater is in use,
and they should be taught to avoid the hot surface.
Keep any objects that can burn well away from the
Heater, and observe the recommended clearances
that follow.
Locating the Stove
In choosing a location for the stove, consider:
• The location of outside walls;
• Where additional heat is needed:
• Where family members gather most often;
• The vent system requirements.
NOTE: We do not recommend the use of wallpaper next
to this stove. Over time, radiant heat may cause the
wallpaper to shrink, or may adversely affect the binders
in the wallpaper adhesive.
Clearance Requirements
Minimum Clearances to Combustible Materials
Measure side clearances as shown in Figures 3 and 4
from the outer edge of the cast iron stove top. Measure
rear clearances from the outermost surface of the steel

WARNING:
• Always maintain required
clearances (air spaces) to nearby combustibles
to prevent fire hazard. Do not fill air spaces with
insulation. All venting components must
maintain a 1" (25mm) clearance to combustible
materials. Maintain a 6” (150mm) clearance
when using single wall pipe.
• The gas appliance and vent system must be
vented directly to the outside of the building and
never be attached to a chimney serving a
separate solid fuel or gas-burning appliance.
• Refer to the manufacturer's instructions
included with the venting system for complete
installation procedures.
