LOCATING THE ROOM HEATER

AS A LOCATION IS SELECTED, KEEP THE FOLLOWING IN MIND:

1. Keep the chimney connection as short as possible.
The heater must have its own chimney flue. Do not
connect any other appliance to the same flue. If there
is no chimney where you wish to place the heater, you
can use a UL Listed Type 103 HT, Solid Fuel, Factory
Built Chimney. (Figure 7)

2. Place the heater on solid masonry or solid concrete.
When the heater is used on a combustible floor, use a
non-combustible floor protector having a thermal con
ductivity of K=0.45 BTU in./ft. 2 hr.deg. F. with 28
gauge sheet metal or a UL Listed Floor Protector.

MINIMUM CLEARANCE TO COMBUSTIBLE WALLS

Have the floor protector extended 14-1/2" in front of the
hearth extension, 1-3/4" to each side, 10-3/8" to the
rear underneath and 2" to each side of the chimney
connector. (See Figure 2)

3. Check Figures 2, 3, & 4. You should have at least the
clearances shown from the heater and the connector
pipe to combustible surfaces. If you have a solid brick
or stone wall behind your heater, you can place the
heater as close as you wish to the wall. If the wall is only
faced with brick or stone, treat it as a combustible wall.
