FLOOR PROTECTION
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.
CHIMNEY CONNECTOR AND CHIMNEYS
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.
