12 GAS CONNECTION P ART 3. GAS CONNECTION A. GAS CONNECTION The gas supply shall have a maximum inlet pressure of less than 14" water column (350 mm), ½ pound pressure (3.5 kP a), and a minimum of 3.5" water column. The entire piping system, gas meter and regulator must be sized properly to prevent pressure drop greater than 0.
13 W ARNING F ailure to follow all precautions could result in fire, explosion or death! GAS CONNECTION It is recommended that a soapy solution be used to detect leaks. Bubbles will appear on the pipe to indicate a leak is present. The gas piping must be sized for the proper flow and length of pipe, to avoid pressure drop.

34 ST ART -UP PROCEDURES P ART 6. ST ART -UP PROCEDURES A. SEQUENCE OF OPERA TION 1. When power is first applied to the control, the control display will read the outlet tempera- ture. The control will initially run through a self-diagnostic routine and then go into its oper- ating mode.
35 ST ART -UP PROCEDURES the room thermostat is connected and turn the room thermostat up above room temperature to start the combustion blower fan to run the Munchkin. The Munchkin will now run its pre- purge cycle, then begin running, which will be indicated by the Green light illuminating under “Flame On ” in your display .
36 12. If the appliance will not operate, follow the instructions “T o T urn Off Gas T o Appliance” Section E and call your service technician or gas supplier . E. ADJUSTING THE TEMPERA TURE ON THE MUNCHKIN DISPLA Y : 1. Before you can change the temperature from the factory setting of 180 degrees.
37 G . TEST MODE This function is intended to simplify the gas valve adjustment if needed. Listed below are the recommended limits on each Munchkin Heater and the Combustion Settings. Automatic modulation does not take place when the controller is in T est mode, only temperature limitation based on the Munchkin Central Heating set point.
38 C A UTION This appliance has wire function labels on all internal wiring. Observe the position of each wire before removing it. Wiring errors may cause improper and dangerous operation.
