FIGURE 5 - FLOOR PROTECTION

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 constructed

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 instruc-

tions 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.

The 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 ﬁ gure 6). The chimney connector should extend

at least two inches into the ﬂ ue of a factory-built chimney. When mak-

ing 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 connector

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.
