Anleitung Zusammenfassung


Honeywell VR8205 Gas Valve with Control Knob Turn knob on gas valve clockwise 41_ to OFF. Do not force, See figure 28, White Rodgers 36G Gas Valve -Move gas valve switch to OFF. See figure 29, 7 -Wait five minutes to clear out any gas. If you then smell gas, STOP! Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions. If you do not smell gas go to next step.

See figure 28, White Rodgers 36G Gas Valve -Move gas valve switch to ON, See figure 29, 9 -Replace the upper access panel, 10-Turn on all electrical power to to the unit, 11-Set the thermostat to desired setting, NOTE -When unit is initially started, steps 1 through 11 may need to be repeated to purge air from gas line, 12-If the appliance will not operate, follow the instructions "Turning Off Gas to Unit" and call your service technician or gas supplier, Turning Off Gas to Unit 1 -Set the thermostat to the lowest setting, 2 -Turn off all electrical power to the unit if service is to be performed, 3 -Remove the upper access panel, 4-Honeywell VR8205 Gas Valve with ON/OFF Switch -Move gas valve switch to OFF, See figure 27. Honeywell VR8205 Gas Valve with Control Knob Turn knob on gas valve clockwise clio to OFF, Do not force, See figure 28, White Rodgers 36G Gas Valve -Move gas valve switch to OFF, See figure 29, 5 -Replace the upper access panel. Heating Sequence Of Operation 1 -When thermostat calls for heat, combustion air inducer starts, 2 -Combustion air pressure switch proves combustion air inducer operation. Switch is factory set and requires no adjustment, 3 -After a 15 second prepurge, the hot surface ignitor energizes, 4-After a 20 second ignitor warm-up period, the gas valve solenoid opens, 5 -Gas is ignited, flame sensor proves the flame, and the combustion process continues, 6 -If flame is not detected after first ignition trial, the ignition control will repeat steps 3 and 4 four more times before locking out the gas valve ("WATCHGUARD" flame failure mode), The ignition control will then automatically repeat steps 3, 4, 5, and 6 after 60 minutes, 7-To interrupt the 60-minute "WATCHGUARD" period, move thermostat from "Heat" to "OFF" then back to "Heat", Heating sequence then restarts at step 1. Gas Flow (Approximate) 1 -Operate unit at least 15 minutes before checking gas flow. Determine the time in seconds for one revolutions of gas through the meter, A portable LP gas me ter (17Y44) is available for LP applications, 2 -Compare the number of seconds and the gas meter size in table 10 to determine the gas flow rate. Multiply the gas flow rate by the heating value to determine the unit input rate, If manifold pressure is correct and the unit input rate is incorrect, check gas orifices for proper size and restriction, 3 -Remove temporary gas meter if installed, NOTE -To obtain accurate reading, shut off all other gas appliances connected to meter, TABLE 10 Gas Flow Rate (Ft.'_/Hr.)

A minimum of 4.5 in, w.c. for natural gas or 11,0 in, w,c, for LP/propane gas should be maintained, 2-After the line pressure has been checked and adjusted, check the manifold pressure.
