rate is recommended. For each 1,000 feet above sea level, increase the fresh
air opening by at least four (4) per cent. The room should be isolated from any area served by exhaust fans. Do
not install an exhaust fan in this room.
CHIMNEY
Follow the recommendations of the heating unit manufacturer. It must be properly designed, of adequate
size, and should be above the surrounding objects, tilelined, with no obstructions, and be in good state of
repair. The smoke pipe should set flush with the inside of tile and be cemented in place. All cleanout doors
should be sealed.
DRAFT REGULATORS
The use of a draft regulator is recommended and should preferably be mounted in the smoke pipe. Use a
draft gauge to adjust to proper opening. When the burner air supply and draft is properly adjusted, the com-
bustion chamber draft will be approximately .0I " to .02 "WC and the stack draft will be .02' to .04'WC. The
Iarger the installation, the greater the draft will be required at the stack to obtain the .0i " to .02'WC at the
combustion chamber.
NOZZLES
Use the proper size, type and spray pattern nozzle that heater manufacturers recommend. In some cases
of upgrading or conversion installations, the use of 80o Hollow or Solid nozzle are the best to start with.
STARTING PROCEDURE
STARTING BURNER
Be sure main switch is in "off" position, and be sure the thermostat is substantially above room
temperature, the oil tank is filled, all valves are open, and controls set for operation. Adjust air supply on
burner by loosening lockscrew on outer band, and open partially. Open the inspection door and turn on
switch. Prime pump according to the pump manufacturer's recommendations and check pressure. If safety
lockout occurs, reset after I or 2 minutes. Do not run fuel unit dry for more than 5 minutes. When fire is
established make a temporary air adjustment for clean combustion flame, reduce air supply until flame tips
appear slightly smoky, then readjust so flame tips are clean iooking. Leave inspection door open until
chamber is dry. When normal temperatures are reached, close inspection door and adjust draft regulator.
(See column under "Draft Regulators").
rrNAL ADIUSTMENTS
At this point a final adjustment should be used by the use of a COMBUSTION TEST KIT. After operating l0
minutes to warm up unit, a smoke tester should be used to take a smoke reading. We are wanting no greater
than #l (Shell Bacarach scale), less than a #l smoke is desired. Some times a new heating unit requires more
time than this to burn clean due to the oil film on the new heater unit surfaces. Recheck draft and take a CO,
reading over the fire and in the stack. If a large differential between CO, readiners is noted, air leakage is the
most common cause (see column under "Heating Plant"). CO, readings must ali be taken ahead of draft con-
trol. The CO, measured in the stack should be at least 90/of.or oil rates 1.00 GPH or below, and be at least l0%
for all rates over 1.00 GPH. Unit should be started and stopped several times to assure good operation. Open
inspection door, turn off oil valve, and check out safety timing of combustion control. Check operation of limit
controls and thermostat. Check for oil leaks. Note: All installations should be reinspected after I or 2 weeks
of normal operation.
rINAL CHECKS
Be sure air shutter and draft control adjustments are locked, and the controls on heating unit are adjusted
in accordance with the heater and Control Manufacturer's Instruction Sheets.
MAINTENANCE
OILING MOTOR - By proper oiling twice a year, the motor life will be increased; only a few drops of non-
detergent type oil at both motor holes are needed.
FILTER - The oil filter cartridge should be replaced once a year so the fuel oil will not become contami-
nated and plug up fuel pump and nozzle of oil burner.
NOZZLE -
The nozzle should be changed at least once each year before the start-up of the heating
season. Replace with proper nozzle.
COMPONENTS - If for any reason any of the burner parts have to be replaced, always use parts recom-
mended by the manufacturer. Specify part numbers and description when ordering. (lN ALL COM-
MUNICATIONS STATE BURNER MODEL AND SERIAL NUMBERS).
ELECTRODE SETTINGS - This is very important for reliable ignition of the oil; check these once a year in
accordance with the instructions provided in this manual.
FAN & BLO\IIER HOUSING - This must be kept clean, free of dirt and lint; open transformer to check fan
blades from above, Be sure the electric power is off on burner when the transformer is opened up for this
inspection,
