2. Retrieve the two replacement flue gaskets (P/N 60702097 & 60702096) from the heat
exchanger maintenance kit.
3. Install the upper larger gasket (P/N 60702097), ensuring that seals inside and outside the
opening are correctly mated to the flue inlet flange. Orient with the “notch” in the gasket
facing toward you, and match the arrow on the gasket to the square mark on the flue inlet
flange (Figure 4-2).
4. Install the lower smaller gasket (P/N 60702096), ensuring that seals inside and outside the
opening are correctly mated to the flue inlet flange.
