If draft hood spillage occurs, check for blocked flue connectors, vent pipes, and

 

Continued

 

 

 

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.
