If your Smith boiler is not working properly, or is not vented properly, dangerous levels of CO may accumu- late. CO is lighter than air and thus may travel throughout the building. BRIEF EXPOSURE TO HIGH CONCENTRATIONS OF CO, OR PROLONGED EXPOSURE TO LESSER AMOUNTS OF CO MAY RE- SULT IN CARBON MONOXIDE POISONING.
