When selecting a location for the heater, be sure attention is given to the following considerations:
1. If the heater is to be vented into a Listed High Temperature Type HT Factory-Built Residential Type And
Building Heating Appliance Chimney, review the installation instructions for the chimney to comply with
requirements for proper chimney location, height, space requirements, etc.
2. If the heater is to be vented into a masonry chimney, the heater should be located as near the chimney as pos-
sible without failing to comply with the requirements for minimum spacing between the chimney connector,
heater and combustibles. (Be sure chimney is constructed according to NFPA standards.)
3. The location of the heater must provide at least the minimum clearances between the heater, chimney connector
and combustible materials as specified by figures 1, 2, 3, 4.
4. If the heater is to be located on a combustible floor, there must be suitable floor space to install a floor protector
beneath and extending beyond the heater as shown by figure 5 and as described by the Floor Protection
section of this manual.
5. The heater should be located centrally within the area where heat is desired but out of traffic areas to minimize
the likelihood of persons accidentally contacting the hot surface of the heater.
6. The heater should be located away from doorways and central heat outlets and inlets to reduce the chance of
drafts blowing smoke, ashes or sparks out of the heater during refueling or ash removal.
7. The heater should be located where a small supply of wood may be kept conveniently close but not within 36
inches of the heater.
8. Locate the heater so that drapes, curtains, furniture and other combustible materials will not be closer than the
clearances shown by figures 1, 2, 3, and 4 OR install a clearance reduction system. See MINIMUM CLEAR
ANCES TO COMBUSTIBLE WALLS AND CEILINGS section of this manual for details.
SELECTING A LOCATION FOR THE HEATER
BUILDING CODES AND SAFETY STANDARDS
These instructions comply with the applicable
National Fire Protection Association and Underwriters’ Laboratories, Inc.
Standards for the installation and operation of this type heater. Before beginning the installation, you should check with
local building officials to assure compliance with local regulations and codes.
This heater is safety listed by Warnock Hersey International, Inc. as specified by the listing label attached to the heater.
HOW THIS HEATER OPERATES
The chimney draft draws in combustion air through an adjustable air inlet thermostat located inside the cabinet. Air
flows through and across the bed of fuel, causing the fire to progress through the fuel bed. Heat is transferred to the air
that flows between the cabinet and the firebox. Any attempt to alter this air by connecting this heater to a duct system
or air movement fans other than the optional KB902 listed blower, available from your heater dealer, can lead to im-
proper and possibly hazardous operation of this heater.
