- Wire the unit to the electrical supply according to the wiring diagram in the full installation manual. This includes connections for the fan, combustion blower, and integrated circuit board.
Venting:
The unit is compatible with Category I double-wall B-vent pipe for vertical or horizontal venting. Ensure the vent pipe is properly sized, installed, and sealed to safely exhaust combustion byproducts.
Operating Instructions
Once installed and all connections are verified, follow these steps to operate your Reznor UDXC-150 unit heater:
- Power On: Ensure the main electrical supply to the unit is switched on.
- Gas Supply: Open the manual gas shut-off valve to allow LP gas to flow to the unit.
- Thermostat Setting: Set the thermostat to your desired temperature. The unit will automatically cycle on and off to maintain this temperature.
- Heat Output Selection: The UDXC-150 offers two heat output levels. Refer to the full manual for instructions on how to select between low fire (87,150 BTU) for milder conditions and high fire (124,500 BTU) for colder periods.
- Initial Startup: Upon initial startup or after a prolonged shutdown, it may take a few minutes for the gas lines to purge air, and the unit may attempt ignition multiple times before successfully lighting.
- Shutdown: To turn off the unit, lower the thermostat setting below the ambient temperature or switch off the main electrical supply. For extended shutdowns, close the manual gas shut-off valve.
