Installation and maintenance must be performed only by qualified personnel who are trained and experienced with this type of equipment and familiar with local codes and regulations.

LOCKOUT/TAGOUT all power sources prior to servicing the equipment.

Hot surface hazard. May cause minor to moderate personal injury. Allow burner assembly and chimney flues to cool before servicing equipment.

Prevent snow levels from blocking airflow into the furnace vestibule and combustion air inlet. Ensure snow does not accumulate and interfere with the operation of electronics within the vestibule.

Routine maintenance should cover the following items:

Unit Storage (Location): The Rebel is an outdoor unit. However, the construction schedule may dictate storage either on the ground or in its final position at the site.

If the unit is stored on the ground, additional precautions should be taken as follows:

Preparation for Storage: Supply (and Return) Fans

Turn the supply and return fan manual motor protectors (MMP) to the OFF position

Check combustion inducer fan for dirt buildup and lint

Check combustion air intake louvers and flue box/vent for accumulation of dirt and debris

Inspect and clean flue tubes and combustion chamber

Dirt and debris can result in poor combustion and lower efficiency

Sign off on the rooftop system maintenance

Check cabinet air filters and replace if dirty

After heavy snowfall verify that combustion air intakes are not blocked by snow

Periodically check during periods of snow accumulation as drifting may also lead to combustion air intake blockage

Check vent terminal screens for blockages and accumulation

Heater and the Venting System: Shall be inspected once a year by a qualified service agency

Gas Train: Check all valves, piping and connections for leakage with a rich soap solution or UL 913 combustible gas leak detector. Any bubbling is considered a leak and must be eliminated.

Inspect and clean flame rod, ignition electrode, and burner manifold

Condensate Pan and Drain: Remove any debris that may have accumulated in the drain pain and drain

After heavy snowfall, verify that combustion air intakes are not blocked by snow

Periodically check during periods of snow accumulation as drifting may also lead to combustion air intake blockage
