WeatherMaster® Single-Packaged Rooftop Units 48P: General Maintenance
This procedure is for the general maintenance and cleaning of your Single Packaged Rooftop Units. It focuses on the cleaning, inspection of main burners flue gas passageways to name a few.
FLUE GAS PASSAGEWAYS (48P ONLY)
The flue collector box and heat exchanger cells may be in- spected by removing heat exchanger access panel, flue box cover, and main burner assembly (Fig. 46 and 47). If cleaning is required, remove heat exchanger baffles and clean tubes with a wire brush.
Use caution with ceramic heat exchanger baffles. When installing retaining clip, be sure the center leg of the clip extends inward toward baffle. See Fig. 48.
