DAKA Furnace Model 622
2008 Edition
Rev 2B: 11-9-12
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.
C. Smoke Bypass Damper
Due to the extra long smoke baffle in this model, designed to create the longest
possible flame path for maximum heat extraction, a sliding smoke bypass damper
plate, controlled by the damper rod over the fire door has been provided. Before
opening fire door for reloading or checking fire, pull the damper rod out fully to allow
the smoke to exit at rear of chamber, rather than rolling forward and possibly spilling
into the room. After closing fire door, push damper rod fully in to seal rear vent.
VIII. EMERGENCY OPERATION INSTRUCTIONS
A. Operation During Power Failure
1. Remove furnace filter(s) to prevent fire hazard.
2. Continue firing the fire with smaller loads, more frequently tended.
3. Use extreme care and vigilance during power failure to keep furnace from
overheating, which could cause severe warpage or breakage.
4. The air jacket top and side may be removed to provide more radiant heat to
help cool the firebox.
CAUTION: DO NOT expect the DAKA furnace to keep the house as warm
during a power failure as when power is on. Do no 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. Reduce room thermostat to lowest point to shut off draft blower. Use chimney
fire extinguishing flares if you have them. (Available at your local home store
or fireplace and woodstove shops).
3. After chimney fire, do not attempt to use chimney again until a professional
inspection is made to determine safety.
