FRESH AIR FOR COMBUSTION AND VENTILATION

Example 2: Locating Heater in Confined (Closed) Area

NOTICE

A confined area has an air volume of less than 50 cubic feet for each 1000 BTU/Hr input rating of all appliances in the area (cubic feet equals length x width x height of area). Include adjoining rooms only if there are no doors between the rooms.

If you install this heater in a confined area, you must provide additional fresh air.

Ventilating Confined Area

This fresh air would come from an adjoining open area or outdoors.

WARNING

The adjoining open area must have enough fresh, outside air ventilation to supply any appliance in that area plus the confined area. Follow instructions under Example 1: Locating Heater in Unconfined (Open) Area, page 15 to make sure fresh air ventilation is adequate.

When ventilating to an adjoining open area, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two areas. Follow the National Fuel Gas Code NFPA 54/ANSI Z223.1. It lists fresh-air requirements for fuel-burning appliances.

After providing ventilation between rooms, check for draft hood spillage (see Draft

Hood Spillage Test, page 15). If draft hood spillage still occurs, provide more ventilation between rooms or provide permanent ventilation from outdoors. See
