F. 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 (Part 3: Gas Connections). Automatic modulation does not take place when the controller is in Test mode, only temperature limitation based on the Munchkin Central Heating set point. The user will be allowed to increase or decrease the fan speed by pressing in either the S1/- or S2/+ keys.
To activate the Test mode simply press the S2/+ and S3/Program key together for 1 second. Once activated, you will see in the display Ser and the actual fan speed. The measurement of the combustion levels should always be taken at the highest and lowest fan speed. After 10 minutes, the Test mode stops automatically. To exit Test Mode press S1/- and S2/+ key together for 1 second.
G. TO TURN OFF GAS TO APPLIANCE
1.Set the thermostat to lowest setting.
2.Turn off all electric power to the appliance if service is to be performed.
3.Remove the front cover.
4.Turn gas shutoff valve clockwise to "off". Handle will be vertical. Do not force.
5.Install front cover.
