Manual-Reset Safety Limit Switch

This appliance is equipped with a manual reset

blocked ﬂ ue safety limit switch. Refer to Figure

5 on Page 8 for its location. If, during appliance

operation, the ﬂ ame goes out (independently of

the burner on/off wall switch), it may be due to

the operation of this safety limit switch. First

allow the appliance to cool. Remove top louver

panel. Then reset the safety limit switch by

pushing the red reset button, located between

the wire terminals, on the back of the switch.

See Detail A of Figure 5 for location.

The appliance should then relight and remain

lit. Reinstall top louver panel. If the appliance

does not relight, turn off the appliance and call

for a qualiﬁ ed service technician.

TO REPLACE THE BLOCKED FLUE SAFETY

LIMIT SWITCH

NOTE - This procedure should only be performed

by a qualiﬁ ed service technician.

Important - Turn electrical power off before

beginning this procedure.

For steps 1-10 below, refer to Figure 5 on

Page 8 (Details B and C):

1 - Lower the bottom control compartment

access panel. Remove the glass enclosure

panel: open the latch (located in the center

of the unit front opening, under the ﬁ rebox

ﬂ oor) securing the glass enclosure panel.

Remove the panel by tilting it outward at

the bottom and lifting it up. Set the door

aside protecting it from inadvertent dam-

age. See Figure 6 on Page 8.

2 - Remove the lintel securing screws (3) and

then remove the lintel. One of the lintel

cabinet top holes is shown in Figure 5

(Detail B).

3 - Remove the scoop securing screws (3)

and then remove the scoop. See Figure

5 (Detail B).

4 - Remove the safety switch bracket securing

screws (2), and pull the switch/bracket

assembly, with low voltage wires attached,

through the side panel slot into the ﬁ rebox.

See Figure 5 (Detail C).

5 - Replace the switch.

6 - Reinstall the switch/bracket assembly.

7 - Reinstall the scoop and lintel.

8 - Reinstall the glass enclosure panel.

9 - Raise the bottom control compartment

access panel.

10 - The appliance should then relight and

remain lit. If this does not occur, check

unit for a blocked ﬂ ue condition.

WARNING

Do not operate the shutoff lever

unless a complete outside combus-

tion air system has been installed

with your appliance.

To open the outside air shutter, open the bottom

control access panel, reach into control com-

partment and pull the combustion air control

lever all the way out. The outside air shutter

should be fully open when the ﬁ replace is in

use and completely closed when the ﬁ replace

is not being used. Closing it when not in use

will prevent outside cold air from entering the

dwelling.

Step 13. Spillage Test and Safety Limit

Switch Operation

Spillage Test

After appliance installation, perform this spill-

age test to verify that proper venting conditions

exist:

1 - Place unit in its normally-operated condi-

tion, that is, with the glass enclosure panel

in place.

2 - Close all doors and windows in the room.

Turn on all exhaust fans in the house.

3 - Light the appliance.

4 - Wait 15 minutes.

5 - To check for venting action, start by holding

a smoke producing device within an inch

of one edge (side edge, not top or bottom

edge) of the glass enclosure panel. The

smoke should be drawn toward the edge

of the glass enclosure panel. Continue the

test by moving the smoke producing device

along the entire length of both side-edges

of the glass door.
