Testing CAP System Operation
1
With the CAP System installed and the cover securely
mounted, initiate a call for heat and allow the burner to
fire.
2
With the burner firing, move the
Test Lever to the TEST position
for 20 seconds. The burner will
shut down following the 20 second
delay.
NOTE: The 70200 will allow the
burner to recycle three times to prevent nuisance
shutdowns caused by temporary blockages 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 signif-
icant amount of air is leaking into the cover or back plate, the
burner will not shut down during the test. Check for proper
installation of all components in the Burner Seal Kit.
• 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 is 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 in-
structions below:
1
Remove the switch cover which is secured by two mount-
ing screws (shown above).
2
Unplug the two female fast-ons from the switch.
3
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
