MAINTENANCE
1. Inspect the system annually to ensure proper operation by observing that the fan activates when a call for heat occurs
and deactivates when the call for heat is satisfied.
2. Disconnect power to the CAS unit and repeat Step 1. NOTE: The unit should not run and the appliance should not fire
in this condition.
3. Inspect the duct pipe for loose joints, damage, and security to the CAS unit and StarKap.
4. Clear any obstructions, if present, from the inlet of the StarKap and the outlet of the CAS unit.
5. Periodically, the fan blade chamber may need cleaning. First, disconnect the power supply to the CAS. Next,
disconnect the duct pipe from the unit. Then remove the top pan and clean the fan housing area as needed. Reattach
the top pan, reconnect the duct pipe and the power supply. CAUTION: A minimum clearance of 1” must be
maintained between the bottom of the fan blade and the top of the metal surface underneath. FAILURE TO
MAINTAIN THIS CLEARANCE MAY RESULT IN A FIRE HAZARD AND WILL VOID THE WARRANTY.
