Y our furnace is capable of putting out many BTU's, so don't fully load your furnace until you have be- come familiar with the operation of the furnace. Keep in mind, a full load will not always give you the best results for your needs.
USSC Page 17 BURNING COAL Y our furnace is capable of bur ning both Bituminous and Anthracite coal. Anthracite is perhaps the best coal fuel because its long even burn time, high heat output, and cleanliness make it a good choice for the home.
Page 18 USSC If, however , there is no flame then the fire needs more air from the bottom (unless it is near the end of its burn cycle and needs to be recharged). Only when the coal is burned down to half its origi- nal depth is it time to add fresh coal.
USSC Page 19 Whenever the loading door is opened, it should be cracked slightly (for about ten (10) seconds) to allow oxygen to enter and burn any combustible gases that are present before fully opening. Failure to do this could result in sudden ignition of the unburned gases when the door is opened.
Page 20 USSC TROUBLE-SHOOTING, PROBLEM SOL VING FOR YOUR FURNACE 1. 2. 3. Problem: Smoke puffs from furnace. Solution: Check chimney draft. Check for blocked chim- ney or flue pipe. Use mirror to check chimney clearance. Check ash pit - if too full, empty.
