PART 2: HOW THE MUNCHKIN CONTENDER OPERATES

(CONT’D)

Inc.) A condensate filter, if required by local

authorities can be made up of lime crystals,

marble or phosphate chips and will neutralize

the condensate. This can be done in the field

by the installer or you may purchase one from

Heat Transfer Products, Inc. (P/N N1100). It is

also very important that the condensate line is

not exposed to freezing temperatures or any

other type of blockage. Plastic tubing should

be the only material used for the condensate

line. Steel, brass, copper or others will be

subject to corrosion or deterioration. A second

vent may be necessary to prevent condensate

line vacuum lock if a long horizontal run is

used. Also, an increase in pipe size may be

necessary to drain properly. Support of the

condensation line may be necessary to avoid

blockage of the condensate flow.

13. Spark ignition

The burner flame is ignited by applying a high

voltage to the system spark electrode. This

causes a spark from electrode to ground.

14. The Vision 1 Optional System

The Vision I System will allow the installing

contractor to take the highly efficient

modulating Munchkin Contender and make it

even more efficient by controlling the

temperature delivered to the central heating

circuits based on the outside temperature. The

Vision I system is also a two temperature

system, one temperature for central heating

and the other temperature to the Super Stor

Ultra Indirect water heater. This allows the user

to increase the temperature supplied to the

Super Stor Ultra Indirect Water Heater to get a

fast recovery by prioritizing the flow at a higher

temperature than may be needed for the

central heating circuits (this will require two

separate circulators). You must follow the

piping, wiring and programming instructions

located in the Vision One section of this

manual. Optional kit consists of the following

• Outdoor sensor – 7250P-319

• Indirect tank sensor – 7250P-325
