Customer Q&A with Product Specialists

Stephen D. from Albuquerque, NM. asked:
I have a Flagro THC-355CDF unit and a project located at 6,600 feet ground elevation. Do these units require reconfiguration for high altitude? If so, what is the reconfiguration time, if there is an added cost, and does the warranty be affected at these higher altitudes?
I have a Flagro THC-355CDF unit and a project located at 6,600 feet ground elevation. Do these units require reconfiguration for high altitude? If so, what is the reconfiguration time, if there is an added cost, and does the warranty be affected at these higher altitudes?
We were unable to confirm from Flagro's published specifications whether the THC-355CDF dual fuel tent heater requires any reconfiguration for installation at higher elevations, such as 6,600 feet above sea level. Because altitude adjustments on a gas-fired appliance affect combustion and are a safety consideration, this needs to be confirmed directly with Flagro before installation at that elevation. Therefore, we cannot provide information regarding reconfiguration time, added cost, or warranty status without manufacturer confirmation. I am currently checking on this and will follow up with a separate email once I have confirmed answers from the manufacturer.
