Invoice Summary – 2016 Lennox Two-Stage Propane Furnace Call type: Heating performance concerns / diagnostic Brand: Lennox (Two-Stage, Propane) Work Performed: - Performed diagnostic and maintenance on the furnace. - Found inshot burners heavily rusted, with partial blockage causing intermittent misfires. - Condensation (in summer mostly)is dripping into the furnace where the air intake line enters, directly onto the burners and gas valve. - This ongoing moisture exposure is causing rust and deterioration. - Propane is more corrosive than natural gas, which can accelerate rusting in these conditions. Results: - Furnace runs but has intermittent ignition issues due to rusted/clogged burners. - Gas valve shows corrosion and may fail in the future. Recommendation: - Replace all inshot burners. - Replace the gas valve due to rust and its increased failure risk in propane systems. - Relocate the air intake entry point to the side of the furnace to reduce future condensation exposure. - R
