than seven grains).

 

Booster pumps may be obtained from Sun Tec Hydraulics, Rockford, Ill.

bottom of storage tank but stop slightly above suction lines. Use a minimum of fit-

4. When installing an oil water heater with an existing oil tank and lines, check exist-

 

 

 

 

 

 

 

ing line sizes and compare to instructions shipped with the pump to see if they are

 

 

 

 

 

 

 

adequate. Do not use existing lines if they are smaller than 1/2" O.D. tube on

 

 

 

 

 

 

 

Models 361E and 541E. Proceed as follows:

 

FIGURE 2

 

 

 

 

 

 

 

 

 

 

A. If existing oil heater has a one-pipe system, tee into the system to furnish oil to the

 

 

 

 

 

 

 

 

 

 

 

heater.

 

 

 

 

 

 

 

 

 

 

 

 

B. If the existing oil heater has a two-pipe system, check whether the return line extends

 

 

 

 

 

 

to the bottom of the tank. It may be preferable to change the existing oil heater to a one-

 

 

 

 

 

 

pipe system and change the return line to the suction line for the heater.

 

 

 

 

 

 

C. If (B) is not applicable, tee into the existing suction line and the existing return line to

 

 

 

 

 

 

supply oil to the heater. Both suction and return lines must extend to the bottom of the

 

 

 

 

 

 

tank, but if the tubing is too small and a two-stage pump is on the existing oil appliance,

 

 

 

 

 

 

the water heater pump may be starved for oil.

 

 

 

 

 

 

D. If return lines do not extend to the bottom of the tank, use check valves on each suc-

 

 

 

 

 

 

tion line as close to each burner as possible to prevent air from being drawn through the

 

 

 

 

 

 

return line.

 

 

 

 

E. Before teeing into an existing oil line, check the vacuum gauge in the 1/4" inlet port or the vent

 

 

 

 

opening. A single-stage pump should not exceed 12" hg vacuum and a two-stage pump should not

 

 

 

 

exceed 17" hg vacuum on two-pipe systems.

 

 

 

 

If the heater performs poorly, recheck the vacuum reading – a high reading will indicate too much

 

 

 

 

resistance. This could be caused by a clogged filter, a restricted shutoff valve, kinked tubing, an ob-

 

 

 

 

struction in the oil line, excessive lift or too long a run.

 

 

 

 

F. If none of the above installations are suitable, Bock recommends an oil booster pump located as

 

 

 

 

close to the oil supply as possible. Use the existing supply and return lines for the booster pump.

 

CONNECT TO

 

Change the existing unit to a one-pipe system and tee off the one pipe to supply oil to the water heater.

 

 

Using “L” or “A” type venting, connect the heater to the chimney. Do not reduce the smoke pipe diam-

 

CHIMNEY

 

eter; use the same size smoke pipe as the heater flue pipe. Run a separate connector from the heater

 

 

to the chimney where possible. If the heater must be joined to another oil appliance breaching before

 

 

 

 

going into the chimney, enlarge the existing breaching to accommodate the extra volume of gases from

 

ELECTRIC WIRING

 

the heater. The entrance into the breaching should be at a 45O angle.

 

 

Wiring must be done in accordance with the National Electrical Code and local ordinances. Burners are

 

 

supplied with an operating thermostat (Honeywell L4103A or Carlin EZ-Temp 90000B on 72E,

 

 

 

 

Honeywell L4006A or Carlin EZ-Temp 90000C or Carlin EZ-Temp 90300B on the 73E through 361E,

 

 

 

 

and Honeywell L8100C or Carlin EZ-Temp 90300B on 190E and 541E). Models 73E through 541E

 

 

 

 

equipped with Honeywell controls are also supplied with a separate L40801B high limit (see wiring dia-

 

 

 

 

grams). The operating thermostat should be set at 120OF for normal domestic hot water use; higher

 

 

 

 

temperatures increase the risk of scalding. Do not set higher than 180OF. The differential control wheel

 

 

 

 

on the L4006 control (73E-361E) should be set to 15OF. The high limit control (L4080B used on 73E-

 

PUTTING HEATER

 

541E) should be set 20OF or higher above the operating thermostat setting. The maximum setting is 200OF.

 

 

Fill the heater with water, opening a hot water faucet to allow trapped air to escape. Check handholes for

tightness. Check the fuel supply and all fuel lines for tightness. Rotate the blower wheel to loosen the

 

 

pump shaft seal. Bleed air from the oil line by opening the bleed valve on the fuel pump. Attach a small

 

 

 

 

plastic tube to the bleed valve fitting on pump and run to a gallon container. Turn on the electricity and set

the line until the oil is completely clear (not milky or opaque), transparent and free of air bubbles and froth.

 

 

 

 

Shut the bleed valve and the burner will ignite. Remove the plastic tube. To keep the burner control from
