GAS-FIRED BOILER Boiler Manual
PART 2: HOW BOILER OPERATES(CONT’D)
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.
11. 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.
12. The Vision 1 System
The Vision I System will allow the installing
contractor to take the highly efficient
modulating Munchkin 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. The Vision 1 kit consists of the
following, which is included with your
equipment
• Outdoor sensor – 7250P-319
• Indirect tank sensor – 7250P-325
PART 3: PREPARE BOILER LOCATIONA. BOILER LOCATION SHOULD BE LEVEL
CAUTION
When preparing the boiler location, make sure the area where you are placing the boiler is level. In order
for the condensate to flow to the location of the condensate hose, the boiler must be slightly pitched
back to assure proper flow direction. The Munchkin Boiler comes equipped with leveling feet. Should
you find the floor beneath the boiler is uneven, with a wrench, adjust the leveling feet so the boiler is
pitched back at 1/8” per foot
