If propane is used, be aware that with a tank that is too small (i.e., under 100 lbs, if this
is the only gas appliance in the dwelling—see NPFA 58), there may be a loss of pressure.
This can result in insufficient fuel delivery that can cause sooting, delayed ignition, or other
malfunctions. Any damage resulting from an improper installation is not covered by the
limited warranty.
