Therefore, when operating at less than full output, the heater does not have its full heating capacity to warm the flue pipes to create a natural draft. Most gas appliances have longer duty cycles than are typical of instantaneous heaters. For many gas appliances, it is con- sidered sufficient if the appliance can overcome a downdraft within the first five minutes of op- eration.
An "on demand" instantaneous heater like the AquaStar may have frequent operating cyles of less than a minute. If venting and air supply are inadequate to provide a positive draft as soon as the heater turns on, the heater may not remain on long enough to establish a positive draft. See venting guide on page 27.
