1. INSTRUCTION MANUAL DISPOSAL OF ASHES Ashes should be placed in a metal container with a tight fitting lid The closed container of ashes should be placed on a non combustible floor or on the ground well awav from combustible materials pending final disposal If the ashes are disposed of by burial in soil or otherwise locally dispersed they should be retained in the closed container until all cinders have thoroughly cooled WARNING Ashes usually contain live dormant coals which may burn for many hours after a recognizable flame has disappeared Use extreme caution when handling and disposing ashes IMPORTANT No other waste shall be placed in this container 1 5 2 SERVICING The furnace air filter must be checked monthly and replaced each year Annually lubricate the blower motor if it is not permanently lubricated with 4 6 drops of SAE 30 oil in each bearing CAUTION Failure to keep air filter clean will result in poor furnace performance and possible damage to wood furnace heat exchanger 1 66 SAFETY If the furnace overheats due to improper operation the following precautions should be taken 1 DO NOT shut off power The blower must be kept running to disperse excessive heat 2 Manually close the damper door by unhooking the chain 3 Check controls for proper operation before starting a new fire WARNING The maximum opening of the combustion air damper is preset at the factory DO NOT adjust the stop o2.
