I have the Santa Fe model and I am concerned that the constant cycling ON and OFF will dramatically shorten the life of the igniter. Is there a setting that will keep the fire in the burn pot at a minimum by adding a small amount of pellets to keep the fire going and then add more when the thermostat calls for more heat? I have been running it on LOW with the thermostat cranked over to very hot to avoid the cycling. Any thoughts on this or is the cycling just part of normal operation and can't be avoided? Thank you.
