This heater has been designed to prevent excessive temperatures on the fl oor beneath the heater. It is important, however, that a
combustible fl oor be protected by a 3/8 inch minimum thick noncombustible inorganic millboard having a thermal conductivity of k=0.43
BTU/ft.
/in./hr./°F or a listed fl oor protector beneath the heater extending beyond the heater as shown by fi gure 5. The fl oor covering

is required to prevent damage or possible ignition from sparks or glowing embers that might escape the heater during refueling or
ash removal or drop from the joints of the chimney connector.
It is very important to assure safe and satisfactory performance
from your heater that it be properly connected to a correctly con-
structed and maintained chimney. A chimney complying with the
requirements for Type HT chimneys in the standard for Chimneys,
Factory-Built, Residential Type and Building Heating Appliance,
UL 103, or a code approved masonry chimney with a fl ue liner
must be used. If a Listed High Temperature Type HT Factory-Built
Residential and Building Heating Appliance Chimney is used, fol-
low the chimney manufacturer's installation instructions carefully.
If a masonry chimney is to be used, be sure it is constructed to
the National Fire Protection Association (N.F.P.A) and local code
standards. A copy of the N.F.P.A 211 Chimney, Fireplaces, Vents
and solid Fuel Burning Appliances may be obtained from N.F.P.A.,
Inc. Batterymarch Park, Quincy, MA 02269.
T
he Chimney connector (pipe from heater to chimney) must be 6 inches in
diameter and made from 24 gauge or heavier steel. The length of the chim-
ney connector and number of elbows* used should be kept to a minimum.
Moisture that might collect in the chimney should be directed to the heater
by providing a slope of 1/4 inch per foot in a horizontal run of the chimney
connector and installing all pipes with the crimped end toward the heater,
(See fi gure 6). The chimney connector should extend at least two inches
into the fl ue of a factory-built chimney. When making a horizontal connection to a masonry chimney, the connector should extend to
the inside face of the vertical fl ue liner, (see fi gures 7 and 8). When connecting the heater to a masonry fi replace, the chimney con-
nector should extend into the chimney's liner as shown by the side section view of fi gure 4. All chimney connector joints should be
sealed with furnace cement and secured with No. 8 sheet metal screws as described by the TO SAFELY AND PROPERLY INSTALL
THIS HEATER section of this manual. *Use Corrugated Elbows.
DO NO USE MORE THAN TWO 90 DEGREE ELBOWS IN THE Chimney CONNECTOR. Installations which require two degree
elbows must be vented into a fl ue of at least 8" diameter or 8" square to prevent chimney draft restrictions, (see fi gure 2).
DO NOT PASS A CHIMNEY CONNECTOR THROUGH A FLOOR OR CEILING OF ANY KIND. Only Listed Factory-Built Residential
Type and Building Heating Appliance Chimneys or masonry chimneys constructed to N.F.P.A. standards should pass through a fl oor
or ceiling.
