HOW THE FURNACE FUNCTIONS Your HOTBLAST Furnace is designed to be a supplemental or central heating source for your home.
DIMENSIONS OF FURNACE Figure 1 Model 1300 Figure 2 Models 1400/1500/1537G 6
Locating the Furnace 1. The furnace should be located in the same room as the central system and as close as possible, but not closer than 9". There should be no wall between the furnace and the warm air outlet duct that is connected directly to the warm air outlet plenum of the central furnace. (See Fig. 4) 18" 21" 12" 9" 2. Place the furnace on a noncombustible floor. 3. Check figures 3 through 5.
Chimney Connection MASONRY CHIMNEY Before using an existing masonry chimney, clean the chimney and inspect the flue liner to be sure it is safe to use. Make repairs before attaching the furnace. The connector pipe and fittings you will need to connect directly to a masonry chimney are shown. THIMBLE 6" ELBOW 6" BAROMETRIC DRAFT REGULATOR The chimney connection should be as short as possible.
Rules for Connector Pipe Installation 1. The crimped end of the chimney connector fits inside the furnace flue collar. Install additional chimney connectors and elbow with the CRIMPED END TOWARD THE FURNACE. This will allow any condensation in the flue to run back into the furnace. Use 6" dia. steel pipe and elbows for connection to chimney. Never use less than 24 gauge and although blued steel is satisfactory, high temp painted black is much more desirable. (See Figure 8) 2.
CONNECTION OF CHIMNEY CONNECTOR TO A MASONRY CHIMNEY THROUGH A COMBUSTIBLE WALL Figure 8 shows how to connect the chimney connector of a heater to a masonry chimney through a combustible wall. There are five allowable ways that a chimney connector can be connected to a masonry chimney by passing through a combustible wall. NFPA Standard 211 allows the following wall pass-through systems.

Assembly of Furnace 2 Your furnace requires the following items to be assembled or installed by the service person: Feed Door Pull Handle Feed Door Locking Handle Blowers and Blower Controls Electrical Connections 1 B B A A 1. Remove all parts from inside the furnace and inspect for damage, including the firebrick as some breakage could occur during shipment. 2. Assemble the feed door pull handle as shown in Figure 13.
WIRING DIAGRAM Figure 16 NOTE: For model 1300, disregard the wiring (wires M1 & M2) of one blower motor. Wire leads from the distribution blower are usually BOTH BLACK. Makes no difference which leads from the motor(s) connects to the corresponding leads coming out of the conduit.
Installation Please see all methods of Installation at the rear of this booklet. This is a furnace, not a free standing stove. You must direct heated air from 8" outlets away from the furnace, or it will not function properly. 1. This installation must be done by a qualified heating equipment installer. 2. The installation is to be done in compliance with National Fire Protection Association installation standards: No.
Operating Instructions FUEL Models 1300, 1500, 1537G (1400 is WOOD ONLY) Egg size (1-3/16" or larger) bituminous coal for residential furnaces, or any of the specially packed fireplace coals can be used. Coal with a low ash content (2% to 6%) is recommended. Hardwood, 18" to 26" should be split and air dried (seasoned) for 6 months. LIGHTING 1. Set the thermostat on "HIGH" for maximum draft. 2. Open the feed door and place paper and kindling on the grate for starting the fire. 3.
4. If the chimney is operating too cool, water will condense in the chimney and run back into the furnace. Creosote formation will be rapid and may block the chimney. Operate the furnace at a high enough fire to keep the chimney warm, preventing this condensation. Service Hints Do not expect a furnace to draw. It is the chimney that creates the draft. Smoke spillage into the house or excessive build-up of water or creosote in the chimney are warnings that the chimney is not functioning properly.
Trouble Shooting Tips for Warm Air Furnace 1. Problem: Smoke puffs from furnace Solution: A. Check chimney draft. Check for blocked chimney or flue pipe. Use mirror to check chimney clearance. B. Check ash pit — if it is too full, empty. C. Make sure furnace room is not too airtight. D. Make sure all of chimney mortar connections are airtight. E. Check ash drawer. Make sure it’s airtight. F. Check chimney for possible down-draft caused by taller surrounding trees or objects.

Bulletin rc454 a guide to Burning coal in your furnace Furnaces that are capable of burning coal usually will burn both Bituminous and Anthracite coal. Anthracite is perhaps the best coal fuel because of its long even burn time, high heat output, and cleanliness which make it a good choice for the home. However, keep in mind it is a much more difficult fuel to use, requires more care and patience, is not so widely available, and is usually much more expensive than Bituminous.
Bulletin rc454 a guide to Burning coal in your furnace Before adding further fuel, be sure to leave a red spot of glowing coals in the center of the firebox to insure that the fire has not been smothered and to help ignite the 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. BANKING THE FIRE: For extended operation, such as overnight, the fire will need to be banked.
