Zero Clearance Stove
AIR INTAKE ADJUSTMENT SHUTTER: adjusts amount of air flow through
fire. Shown on next page
GEAR MOTOR: The drive shaft turns approximately 1RPM. The nylon cam on
drive shaft will, when moving inward, force coal from hopper onto grate. When
withdrawing, will allow coal to fall in front of pusher bar for preparation of next
inward stroke. The gear motor will only run when activated by a call for heat from
thermostat or when timer turns it on.
COMBUSTION MOTOR: Combustion motor will run all the time to force air
through holes in grate to burn coal hotter. The constant running of motor will
assure the maximum amount of heat is gained and will aid in a more complete
burning of coal. The motor has an adjustable air shutter for regulating air flow
through fire.
TIMER
Unless your stove had been a special order, it will be equipped with our patented
flat grate stoker unit and a timer. The timer is shown on the next page.
The purpose of a timer is to maintain a minimum fire when thermostat is not
calling for heat.
