I just got a high efficiency condensing gas furnace installed. I feel like it was done poorly, but I'm not sure. Some questions I'm wondering about are:
- Do furnaces need to be level? It is visibly tilted, but at least it's tilted so the water drain is lower.
- Does the vent pipe need to be a certain distance from any windows? Mine is almost touching a window.
- Do I need a special thermostat to take advantage of a modulating gas valve? They gave me a thermostat that has 1 or 2 heating stages (1H or 2H). The gas valve has 60 settings (40-100%), but I didn't see any thermostats with more than 4 or 5 stages of heating.
Edit: Furnace model Trane XC95m, thermostat Honeywell T6 Pro wifi
