Furnace Gas?/CO alarm

[Capt Dave]

Hello Everyone. When I run my furnace my LP/CO alarm sounds. I am not getting a CO alarm from a separate battery operated CO detector i set in camper as backup. I know the backup CO detector I set in camper alarms at 35 ppm. How many ppm does the factory installed LP/CO detector alarm? Right now I'm thinking LP leak. ONLY alarms when I run the furnace. Can't say i smell alot of LP. I have a 2020 Flagstaff Micro Lite 21 fbrs purchased in July 2019. The furnace is a Suburban. I am plugged into shore power. Looking for some direction? Much thanks

Is it the 1st time using the heat? If it is it's probably the oils burning off from the new heater,It will get less the more you run it,Try operating it with the vents open and windows open.

The ceiling-mounted alarm sounded immediately on our new EPro when we started the furnace. We were startled, and turned off the furnace. A reviewer suggested that oils from the new furnace may need to be burned off and that we should run the furnace and open all our windows and vents until the alarm stops. Well, we'll certainly need to inform any nearby campers that we're not actually suffocating or on fire, and sorry for the noise! Sure hope this technique solves the problem. Otherwise, we will have no heat when it gets cold.

P.S. In future, is it safe to run the furnace with all vents and windows closed? That's what we do at home, but I don't know about what's safe in the trailer, given our experience.
