NOTES

1. Some applications, usually O.E.M. require the use of more than one extension. Determine the exact number in your ECONOMITE before ordering.

2. 5" and 15" Blower Housing and Blast Tube Assemblies are NOT available. A 5" assembly can be fabricated by hacksawing 4" off of a 9" assembly.
A 15" assembly can be made by assembling a 9" assembly with 2020500 (8" long Accessory Blast Tube Extension).

3. Maxitrol and General Controls Pilot Regulators have been used interchangeably. For exact replacement, determine the model used in your ECONOMITE
before ordering. If inlet pressure exceeds 1/2 PSI or if regulating PROPANE, select 8400-00 (Maxitrol RV12LT) as the RV12LT regulates to 1 PSI and
responds better to PROPANE regulation.

4. Burners have been assembled with valves and regulators built by various manufacturers (i.e. General Controls, Maxitrol, etc.). MIDCO will supply whatever
brand is currently in stock, depending on price and availability. Valve or regulator body length may vary and some replacement problems may occur. 3/4"
NPT and 1" NPT Main Regulators have been used interchangeably, as have 3/4" NPT and 1" NPT Main Automatic Valves. Determine the size used in your
ECONOMITE when ordering. BE CERTAIN OF VALVE SIZE. Many early burners were sized for mixed or manufactured gases, which require larger
piping. Effective June 1978, gas pipe trains were reduced one pipe size, except for one special burner.
Note: MIDCO stocks only complete valves. If magnetic operators or power heads are desired, or if exact replacement of any part is desired, they
should be obtained from local distributors.

5. When replacing Fluid Power Valves, obtain pipe size, exact valve number and brand from valve rating plate, as well as the bill of material number from the
ECONOMITE rating plate. Contact MIDCO for price and availability, if not listed. Construction required dual main automatic valves April 1, 1994 (Date Code

1394). Determine the valve size(s) before ordering.

6. Contact MIDCO for availability of early EC manuals.

7. WARNING: Explosion hazard. Can cause serious injury or death. This device can malfunction if it gets wet. Never try to use a device that has been wetÑ
replace it.

8. DECODING CENTURY MOTOR NUMBERS. Single digit prefix denotes manufacturer's location. Double digit suffix denotes manufacturer's mechanical
code.

9. Honeywell R4795A Flame Safeguards were phased out of production November, 1993. Replaced by Honeywell RM7895 Flame Safeguards. Determine
which version is required before ordering.

10. Honeywell Spark Generator was introduced in July, 1994. As standard construction.
