Condensate Drain Pipe Freezing

[jsdtx]

My Rinnai tankless rur98i showed an error code 25 today and I shut it off and went outside and saw that there was an icicyle hanging from the drain pipe. The unit is in the garage.. In Austin we are going on 3 days of 20 degree weather. Any ideas on whether I can get it working before the freeze lifts? I put a sprinkler cover on it and turned the unit off. Thank you

Turn the unit back on. You need to heat the garage up, defrost the tankless condensate area.
