Page 10: Furnace Location
Furnace location Before you start! It is very important you check with your dealer, local fire department, or building inspector. They will be able to in- form you of any state or local codes pertaining to the loca- tion and installation of your furnace. The ideal location for your furnace is centrally located in the basement. -
Page 11: Clearance To Combustibles
Your furnace is designed to be added on to existing duct work and operate either with or without another heat source such as a gas furnace. The following diagrams illustrate acceptable ways of ducting your furnace. Clearance to Combustible Materials Your Furnace has been tested to determine the SAFE clear- ances to combustible material. -
Page 12: Flue Recommendations
FLUE RECOMMENDATIONS The termination cap should be designed to inhibit downdrafting without restricting the exhaust discharge. The flue termination should be at least 3' above the roof line. Page 12 Chimney experts have determined that the flue termination should be at least 2' above the highest portion of the roof that is within a 10' radius. -
Page 13: Masonry Chimneys
CHIMNEY INSTALLATION With the chimney being the most important part to your installation, great care should be given to its design. MASONRY CHIMNEYS If your intention is to use an existing masonry chimney, check first with your local building official to see if this is acceptable. -
Page 14: Assembly
NOTE: Your furnace may come partially pre-assembled, but in the case that it is not, follow the instruc- tions below. Prior to assembling, place the unit in the general vicinity of the installation. This should help minimize handling damage to the unit after assembly. Note: If your basement can't handle a height of 7' 8" you must lay the furnace on two, 2 x 4's to slide shrouds onto weldment. - Page 15 Attaching furnace control center box. To separate outer cover, remove two (2) side screws and pull off black rheostat knob. Attach box to left side (facing feed door) with four (4) self-threading screws. One screw in each corner. (NOTE: Furnace control center is designed for left side attachment.
- Page 16 CAUTION: Any hot air plenum connection to a furnace must be constructed of metal. 9. Installing collar to top: To install hot air attaching collar, simply bend all tabs right angle under shroud. This may be possible with thumbs, if not, remove top and use small hammer.
- Page 17 13. Installing front and rear cast baffles, heat plates. NOTE: Grate frames and brick will slide forward and backward to allow baffle to fit. Install front cast baffle using two (2) 5/16 bolts, nuts & washers (7/16 wrench will be needed). Place the side of the baffle that has the two ribs against the front weld of the firebox.
- Page 18 17. Reposition door latches, feed and ash door. For shipping purposes, door latches are on backwards. Unfasten 7/16" nuts, reverse and snug fairly tight (latches must move freely). 18.

Ignite the paper and close the door. Do not attempt to open the door immediately after igniting the fire. There could be a flame flash out. It will take a few minutes for the fire to establish itself. Once you have some good red hot burning coals, add larger pieces of wood. -
Page 23: Burning Coal
Keeping your chimney and stove pipe clean is the best in- surance against chimney fires. Note: Smoke detectors and fire extinguishers should always be a part of your equip- ment. If you clean your own chimney and stove pipe, we recom- mended purchasing the equipment professionals use. - Page 24 gases given off by the new charge. A deep charge will give a more even heat and a longer fire, but it may take one to two hours before the whole bed is fully ignited. When the fire is well established and the room is becoming warm, partially close the dampers.
- Page 25 ASHES Ashes never should be allowed to accumulate in the ash pit so that they in any way impede the flow of combustion air to the fire. Excess ash accumulation can cause the fire to go out and also can cause severe damage to the grates because of the absence of a cooling flow of air beneath them.
