CO Shield Questions
Q1: Can I operate my generator inside a shed away from my home?
Q2: Can I operate my generator inside my garage with the exhaust pointing outside?
Q3: Can I operate my generator on my covered porch with the windows and doors closed?
Q4: When the generator shuts off from CO, what should I do next?
Q5: If I approach the generator that has been shut off, and there are no blinking lights, how do I determine what caused the shutoff?
Q6: Why do I still have a CO shutoff if I properly placed my generator outdoors with the exhaust pointing away?
Q7: When the generator shuts off from CO, when can I try to restart it?
Q8: Does CO Shield monitor indoor CO levels?
Q9: Will CO Shield work when my generator is running on propane or natural gas?
Q10: I use my Storm Shield tent to protect my generator from the rain. Will it cause shutoff due to elevated CO under the tent?
Q11: Can I change the sensitivity or disconnect the CO Shield device if it keeps shutting off the generator?
Q12: What can I do to test the CO shutoff feature and make sure it's working?
Q13: How do I run my generator in the rain if I'm instructed to operate my generator outdoors, far away from occupied buildings with the exhaust pointed away from people and buildings?
Q14: Why does my generator’s wireless remote-start feature not work after a CO shutoff event?
