INTRODUCTION Dear Woodchuck Owner, Congratulations on your purchase of a Woodchuck heating appliance. Undoubtedly you have given much consideration to your purchase and we’re proud that you have selected a Woodchuck. Pride in craftsmanship and engineering have made your Woodchuck the finest heating appliance available today. Solid fuels are abundant and inexpensive. Wood is our only renewable source of fuel and conservative estimates put our coal reserves at 800 years.

FURNACE SAFETY THERE ARE INHERENT HAZARDS ASSOCIATED WITH THE OPERATION OF WOOD/COAL FURNACES. FOR YOUR SAFETY READ, UNDERSTAND, AND HEED THE FOLLOWING: DANGER: RISK OF FIRE OR EXPLOSION. DO NOT BURN GARBAGE, GASOLINE, DRAIN OIL, OR OTHER FLAMMABLE LIQUIDS. FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH. DANGER: NEVER USE CHEMICALS OR FLUIDS SUCH AS GASOLINE, CHARCOAL LIGHTER FLUID, DRAIN OIL, FUEL OIL OR KEROSENE TO LIGHT A FIRE IN YOUR WOODCHUCK.

GENERAL INFORMATION more. Here is how: when combustion air enters a Woodchuck furnace it enters into a “draft Woodchuck furnaces represent the ultimate in solid fuel and dual fuel heating appliances. From the massive model 4000 to the economy model 526, each unit is designed to be attractive, durable and efficient while providing the safety and comfort you and your family deserve. channel." Here it comes into contact with the hot firebox front and is warmed before entering the firebox.
enough to operate properly in mild weather, it will not be large enough to keep the house warm in cold weather. This could cause the furnace to overheat and a loss of heat up the chimney. The result then is a compromise which is neither efficient or comfortable. Woodchuck furnaces, however, have a three speed circulation blower which can be adjusted via a three position rotary switch on the Comfort Control Center.
OPERATION ! IF YOU HAVE CHIMNEY FIRE ! COMMON SENSE Please read the following before firing your furnace. It is most important that you follow these suggestions and limitations in order to maintain your warranty and guarantee the long life of your furnace. Meyer Mfg. Corp. recommends the following actions: NOTE: Smoke detectors and fire extinguishers should always be a part of your equipment. 2. Alert everyone in the house. 1. Shut any doors and air inlet dampers and draft control.

NOTE: On airtight units, the burning time is controlled mostly by the draft controls on the furnace, contrary to the old type of pot belly stoves where the smoke pipe damper controlled the burning time. cluded in the owner’s manual package for monitoring stack temperature. Install the flue temperature thermometer at the rear of the furnace on the smoke pipe where it connects to the collar on the back of the Woodchuck.
BURNING COAL IN YOUR WOODCHUCK A coal fire should not be poked or broken up as this tends to bring ash to the surface of the coal bed where it may fuse. If the ash fuses, clinkers will form. It may be necessary to remove all unburned material and ash from the firebox to remove clinkers. These should be removed with gloves or tongs, and as always, put into a metallic air-tight container. Never attempt to burn coal without a shaker grate.
Coal firing produces much more ash than wood. These ashes must be removed often (possibly daily) in order to avoid piling up too closely to the grates. Removal of the coal ash will prevent warpage and damage to grates, and allow passage of primary air to the coal bed. ASH REMOVAL Ash should always be put into an air-tight, metal container. CAUTION · · · · Unlike wood ash, coal ash cannot be used as fertilizer. All coal contains small amounts of dangerous elements.
TROUBLE SHOOTING PROBLEM 1. Main blower vibrating when in use. POSSIBLE CAUSE Loose Allen screw on squirrel cage. SOLUTION Tighten Allen screw, be sure squirrel cage did not move to one side or the other. Bad motor bearings. Return blower to your local dealer for a replacement. Weights on squirrel cage wheel moved in ship- Try to adjust it yourself or return ment. blower for replacement. 2. Main blower continues to Manual control turned on (fan/limit control). Check fan/limit control switch. Push run.
PROBLEM 9. Excessive amounts of smoke coming out loading door when loading. POSSIBLE CAUSE Improper draft. SOLUTION Measure with draft gauge-should have .04 to .06 water column. Chimney cap too close to top of chimney. Relocate. Too long of run of smoke pipe from Woodchuck Relocate Woodchuck closer to to chimney. chimney. 10. Puffing of smoke Improper draft. Check draft with gauge. Should be through draft control. .04 to .06 water column. Down draft on chimney.
INSTALLATION GENERAL REQUIREMENTS CAUTION: EQUIPMENT MUST BE INSTALLED BY A QUALIFIED HEATING PERSON. CAUTION: ONLY “CLASS A” ALL-FUEL OR SOLID FUEL CHIMNEYS INTENDED FOR USE WITH YOUR WOODCHUCK SHOULD BE USED. FIRST AND ABOVE ALL is safety for you and your family. MUST USE: Class A Masonry or ULC listed, manufactured Class A All Fuels Chimney. RECOMMENDED SIZE: Rectangular 8"x12" or Round 8". DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
THE CAP SHOULD BE SUCH THAT IT HELPS TO PREVENT DOWNDRAFT WHILE PROVIDING ADEQUATE EXHAUST DRAFT. MIN. 3’ FROM TOP OF CHIMNEY TO POINT AT WHICH IT PASSES THROUGH THE ROOF TOP OF CHIMNEY MUST BE AT LEAST 2’ HIGHER THAN PEAK OR HIGHEST PORTION OF ROOF WITHIN 10’ HORIZONTALLY. ALSO SEE FIGURE 9. A CHIMNEY WHICH RISES WITHIN HOUSE IS BETTER INSULATED THAN A CHIMNEY WHICH IS LOCATED OUTSIDE THE HOUSE AND IS EXPOSED TO WEATHER.
which can ignite and cause severe damage to any chimney. MAKE SURE YOUR WOODCHUCK IS INSTALLED INTO A PROPER CHIMNEY. Your unit should be place on a non-combustible floor or 3/8" thick fireproof millboard or equivalent which extends at least 8" from the sides and rear and extends 24" from the front. Leave a minimum clearance of 36" in front of your unit. This is for safe, easy loading and cleaning of your unit.
INSTALLATION OF A BAROMETRIC DRAFT When using approved factory built metal chimneys, you must have at least 2" of clearance when going through a wall or next to a wall. A typical factory chimney installation is shown on figure 9. Some codes and NFPA require draft regulators in the chimney connector of wood or coal furnaces and boilers, and manufacturers recommend their use with some stoves. There is some doubt among wood heat experts as to whether use of barometric draft regulators is wise.
MANUAL DAMPER MAY BE INSTALLED BETWEEN BAROMETRIC DAMPER AND CHIMNEY With no draft in chimney, regulator is closed, no air gets in. Moderate suction in chimney pulls regulator open enough to maintain desired draft for appliance. Excessive suction in chimney pulls regulator further open, allowing substantial air into chimney connector. FIGURE 10 A BAROMETRIC DRAFT REGULATOR AND ITS INTENDED EFFECT 600 ft/min to 1000 ft/min at the registers. NEVER supply less than 150 sq. in. of heated air outlet area.

Assemble the left front bar (different from right front bar, has shorter extension shaft at front) to a rear bar. Slide a gear onto the front shaft. OPTIONAL SHAKER GRATE INSTALLATION FOR MODEL 526 1. Remove standard grates from firebox. Assemble complete shaker grate kit outside of unit. Figure 16. 20 3.
4. Assemble the right front bar to a rear bar. Slide a gear onto the front shaft, aligning it to engage the gear on the left bar. Place the front bar onto the front frame and then setting the rear bar onto the rear frame. 5. Place rear retainer in place, then the center and the front retainers. Place all four bolts through retainers and frame. Secure with locknuts. To prevent binding, it is advisable to snug the locknuts but do not over tighten. 6. Try moving the shaker grate bars with the handle.

The pyrolysis of wood produces certain substances which will not burn unless the temperature in the firebox reaches 1000°F or higher. Under normal conditions these temperatures are not attained and these substances simply escape up the chimney as wasted energy and can form deposits in the chimney. By forcing these unburned substances to come into contact with a catalyst, we can cause them to burn at much lower temperatures that are easily attainable during normal operation.
