Testing CAP System Operation

With the CAP System installed and the cover securely
mounted, initiate a call for heat and allow the burner to
fire.

With the burner firing, move the
Test Lever to the TEST position .
The burner will shut down following
a 20 second delay.

NOTE: The 70200 will allow the

burner to recycle three times to
prevent nuisance shutdowns caused by temporary block-
ages or high wind conditions. If the blockage persists the
burner will shut down and lock out after the third recycle
attempt.
NOTE: If the burner does not have a prepurge cycle, the

burner will fire upon recycle, but will shut down following
20 seconds of operation. (See the 70200 instructions for
more details).

Annual Test

Using the instruction above, the CAP System operation should
be tested annually.

Troubleshooting

Burner Will Not Shut Down During Test

If the burner did not shut down with the test damper closed for
a sustained 20 seconds, check the following:

• Make sure that the burner cover

is properly sealed. If

a significant amount of air is leaking into the cover

backplate

, the burner will not shut down during the test.

Check for proper installation of all components in the Burner
Seal Kit (see Step 6).

• Make sure that the burner cover screw

is tight. This also

prevents basement air from entering the cover.

• Check that the correct air pressure switch

installed based on the firing rate of the burner (See table on
page 2 and instructions for changing the switch on this page)

• Make sure Vent Input on 70200 control is set to “Intake” (see

step 11).

Changing the Air Pressure Switch

The air pressure switch

must correspond with

the firing rate of the burner – see table on page 2. Carlin’s
Complete CAP System Kit (51300S) contains all three pressure
switches. Switches are also available separately. If you need
to change the switch to accommodate your application, follow
the instructions below:

Remove the switch cover which is secured by two mount-

ing screws

10c

(shown above).

Unplug the two female fast-ons from the switch.

Pull the switch outward to remove it from the assembly.

Replace it with the switch that corresponds to the burner’s
firing rate. Reattach the wires and secure the switch cover
