and condensate switch
Exis�ng low and high voltage:
- replace exis�ng tstats with Honeywell TH8321WF VisionPRO 8000 Smart Thermostats
- low voltage wiring to be replaced from RTU to T-stat if insufficient for opera�on
- if line voltage wiring is sufficient, use otherwise include replacement breakers and wiring as
needed
The Lennox Enlight is equipped with a non-fused disconnect, if possible, I do not want to have
an addi�onal fused disconnect atached to the RTU. If there is no way around not having the
fused disconnect on the RTU, the RTU needs to be ordered without the non-fused disconnect.
Gas:
- provide all materials needed to connect gas to replacement RTU to include replacing exis�ng
union and ball valve.
Roofing:
- include roof curb adapters
- include high wind hold down brackets
- penetra�ons needing sealed or repairs needing made from installa�on should be compa�ble
with Duro Last Inc. roofing systems.
- I have u�lized Cen�Mark Roofing in the past. Contact informa�on Zac Franke (402)-650-0633
