Draft Hood Spillage: This is a hazardous situation. Draft hood spillage re- leases poisonous carbon monoxide gas into your home.

DANGER

Carbon monoxide poisoning may lead to death!

If draft hood spillage occurs, check for blocked flue connectors, vent pipes, and chimneys. If you find blockage, remove. Test again for spillage. If spillage still occurs or there was no blockage, you need more fresh, outside air in the house. You must provide additional fresh-air ventilation. Follow the steps below at once.

A.Open a window near the appliance(s) at least two inches. Test again for spillage. If spillage does not stop, open window more and retest. If spillage stops, keep window open while running appliance(s). Supply fresh, outside air by a permanent method as soon as possible. If spillage still occurs, leave window open and go to next step.

B.If you have a fireplace, open a window or door near it at least two inches. Test again for spillage. If spillage does not stop, open window or door more and retest. If spillage stops, keep window or door open while using fire- place. Supply fresh, outside air by a permanent method as soon as possible. If spillage still occurs, leave window or door open and go to next step.

C.If you have kitchen and bathroom exhaust fans, turn them off. Test again for spillage. If spillage stops, do not use exhaust fans. Turn off circuit breakers for fans if possible. Permanently supply fresh, outside air as soon as possible.

Providing Permanent Fresh-Air Ventilation

If draft hood spillage occurs, you must permanently supply fresh, outside air to the inside of your house. Provide extra fresh air by using ventilation grills or ducts. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. If you install this heater in an area with other gas appliances, you must total the BTU/Hr input rating of all appliances. Follow the National Fuel Gas Code NFPA 54/ANSI Z223.1. It lists fresh-air requirements for fuel-burning appliances.

IMPORTANT

Do not provide openings for inlet or outlet air into attic if attic has a thermostat controlled power vent.
