This heater has been designed to prevent excessive temperatures on the floor beneath the heater. It is important, however, that a
combustible floor 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 floor protector beneath the heater extending beyond the heater as shown by figure 5. The floor
2
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. If a Listed High Temperature
Type HT Factory-Built Residential and Building Heating Appliance
Chimney is used, follow the chimney manufacturer's installation in-
structions 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 ob-
tained 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
chimney 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 figure 6). The chimney connector should extend
at least two inches into the flue 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 flue liner, (see figures 7 and 8).
When connecting the heater to a masonry fireplace, the chimney con-
nector should extend into the chimney's liner as shown by the side sec-
tion view of figure 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 flue of at least 8" diameter or 8" square to prevent chimney draft restrictions, (see figure 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
floor or ceiling.
