C. Living Area Thermostat (Key No. 22)
The Honeywell T812A1002 thermostat is to be installed in any ground floor room on an inside
wall, preferably beside the thermostat governing the primary furnace which should be set
approximately 5° lower than the DAKA thermostat. When falling room temperatures call for
heat, the DAKA thermostat turns on the 50-cfm front draft blower on the DAKA furnace; the
additional combustion air increases the heat output until the DAKA room thermostat signals the
blower to cut off. Combustion air then reduces to a maintenance level with relatively low heat
output, ready for the next firing cycle. Should there be insufficient fuel to increase the room
temperature as called for, the primary furnace will fire when the temperature falls to the 5°
lower setting. The DAKA draft blower will continue to run; however, to turn it off, lower the
DAKA room thermostat setting below that of the primary furnace.
IMPORTANT: Normal operation will produce flue gas temperatures in the 300°-600°F range. If
higher or lower operating temperatures are normally obtained, increase or decrease the
barometric draft control setting and room thermostat setting to bring temperatures to within
range. Too cool a flue gas temperature can result in heavy creosote formation, while too hot a
temperature increases danger of chimney fire.
VIII. EMERGENCY OPERATION INSTRUCTIONS
A. Operation During Power Failure
1. Remove furnace filter(s) to prevent fire hazard.
2. Close damper plate on draft blower to no more than 1/3 open.
3. Continue firing the fire with smaller loads, more frequently tended. Do not fill above
bottom of door opening.
4. Use extreme care and vigilance during power failure to keep furnace from overheating,
which could cause severe warpage or breakage.
CAUTION! Do not expect the DAKA furnace to keep the house as warm during a power failure as when
power is on. Do not attempt to increase heat output by opening ash door or fire door.
B. In Case of a Chimney Fire:
1. Call the fire department immediately.
2. Close damper plate on DAKA draft blower to cut off oxygen to the chimney. Use
chimney fire extinguishing flares if you have them. (Available at fireplace and
woodstove shops.)
3. After chimney fire, do not attempt to use chimney again until a professional inspection is
made to determine safety.
IX. MAINTENANCE OF YOUR DAKA FURNACE
CAUTION! TURN OFF ALL POWER TO UNIT BEFORE CLEANING.
A. Flue pipe and chimney
These must be checked frequently during heating season and deposits of soot and creosote
over 1/8" thick removed using stiff-wire brushes designed for the job. Professional cleaning by
a chimney sweep at least once a season is highly recommended.
B. DAKA Furnace Blowers
The DAKA blower is self-lubricating and does not require oiling. Vacuum away dust and dirt
on motor air inlets, and also on blower impellers at least once each season.
C. Fire chamber and ash pan
Check ash pan every few days and safely dispose of ashes. Keep ashes from building up on
grate and interfering with combustion air flow from below.
At end of heating season, clean out all residual ashes and soot from furnace. The moisture they
contain could rust your furnace over the summer months, thereby shortening the life of the unit.
