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.

A. This appliance has a pilot which must be

try to repair it, call a qualified service tech
nician. Attempted forceful repair may re
sult in a fire or explosion.
