Are Coleman ProCat heaters suitable for use in tents?

Coleman ProCat heaters are designed for indoor use, specifically areas with proper ventilation, according to the Coleman product page. Other guides, such as Amazon customer reviews, have confirmed that the product works well in tents, reporting multiple successes with the Coleman ProCat heaters while camping, as of February 2015.

Although many Amazon customers praise the heater for keeping their tents warm while camping, the importance of Coleman's insistence on using the heater with proper ventilation should be stressed. The heater emits carbon monoxide, which is not a concern so long as the gas has a way to escape through a well-ventilated area.
