- Page 2 Zero Clearance Stove Safety inspection of a venting system should be performed before and after installing your new stove. Procedures to follow are those recommended by the National Fuel Gas Code, ANSI Z223.1 or refer to local codes or ordinances. Plan the vent system layout before installation to avoid the possibility of accidental contact with concealed wiring or plumbing inside walls.
- Page 3 Zero Clearance Stove Clearances to Combustible Walls On Either Side Locate thermostat in an area where heat from stove can be freely reached. Mount plastic wall plate of thermostat. Connect thermostat wires to screws on lower portion of wall plate. Run thermostat wires to Relay on stove and connect wires to terminals marked T.T.
- Page 4 Zero Clearance Stove USE RICE COAL ONLY. Starting Fire DO NOT USE AN ACCELERANT SUCH AS: gasoline, kerosene, litter fluid, or etc. When thermostat is set higher than room temperature the stoker unit should be running. Find coal feed adjuster (painted white) on stoker unit, and while it is withdrawing, (moving toward you) turn nut counter-clockwise as far as it will go.
- Page 5 Zero Clearance Stove Accumulation of dust on exhaust fan blade. Remove screws on motor mounting bracket, remove motor, and thoroughly clean fan blade. Windy conditions outside of home blowing against exhaust air. Safety switch defective. Replace control. Do not allow ashes to overflow out of ash pan, this can cause blockage in exhaust system.
- Page 6 Zero Clearance Stove VENT TEMINATOR LOCATION Vent terminator may not be located: 1. Less than 1 foot above grade. 2. Above or within 3 feet horizontally of oil tank or gas meter. 3. Closer than 3 feet to inside corner of home. 4.

Page 7: Controls And Their Functions
Zero Clearance Stove CONTROLS AND THEIR FUNCTIONS Thermostat: Top pointer is desired room temperature. Bottom pointer is thermometer. When room temperature drops below setting, combustion blower and gear motor will start. When room temperature rises, combustion blower and gear motor will stop. - Page 8 Zero Clearance Stove Gear Motor: function is to drive feed mechanism (pusher bar) to slide coal from hopper onto the grate, to move the fire forward and the ash into the receptacle. Combustion Motor: To force air through stoker unit to burn coal. Exhaust Motor: To force coal gas fumes from stove to outside.
- Page 9 Zero Clearance Stove Clean glass regularly with a non-abrasive cleaner. Turn thermostat down, open fire door. Place a shield over door opening, apply cleaner. Wipe off cleaner with paper towel. Moisten a clean paper towel with water, wipe glass and dry with paper towel. Maintenance 1.
- Page 10 Zero Clearance Stove DIAGRAM (1) Shows what fire should look like when thermostat calls for heat for extended period A. Unburned fresh coal supply from coal hopper B. Burning Coals C. Ash on lower end of grate (around 2”) The actual length of burning coals will vary as heat demand increases or decreases. If burning coals fall off grate, reduce coal feed by turning white adjustment nut in a counter clock-wise direction 1 or 2 full turns.
- Page 11 Zero Clearance Stove PUSHER BAR: Moves in a reciprocating motion. Activated by cam on gear motor to force coal from hopper onto grate. Also pushes ashes off bottom grate into ash pan. Length of stroke is adjustable by turning coal feed adjustment nut. WHITE COAL FEED ADJUSTMENT: Turn clockwise for more coal feed, Turn counterclockwise for less coal feed.
- Page 12 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.
- Page 13 Zero Clearance Stove The timer is factory set to run 1 ½ minutes every 10 minutes. The timer activates the gear motor, which will cause the pusher bar to move in a reciprocating motion, forcing coal onto grate.\ The timer has a large yellow wheel that makes 1 revolution every 30 minutes. Pins can be inserted or removed from yellow wheel.

Page 14: Fan Limit Switch
Zero Clearance Stove FAN LIMIT SWITCH 1. HIGH LIMIT POINTER-stops gear motor from pushing coal onto grate at 200 degrees (If stove gets too hot, this switch will turn off gear motor). 2. CENTER POINTER-turns convection blower on when internal air temperature reaches this setting (normally set around 160 degrees, but is adjustable). - Page 15 Zero Clearance Stove RELAY-receives signal from 24V thermostat to turn on or turn off gear motor. CONVECTION BLOWER-when running, it will take cool air from room, and force it through heated air chamber inside stove, and return heated air into room. Blower can only be activated by Fan Limit Switch.

When thermostat calls for heat, gear motor should run steady. If gear motor is running steady, but fire is small, increase coal feed. (See pages 11 & 12). If gear motor is not running steady, check for loose wire in Thermostat or in Relay.
