HAND-HELD REMOTE INSTRUCTIONS SUPPLIED
WITH THE REMOTE.
1. Remove cover on control panel to show opening for remote
receiver.
2. Connect the remote connectors located in the unit.
3. Slide remote receiver in the opening of control panel. Use

CHECKING SYSTEM OPERATION
The milli-volt system and individual com-
ponents may be checked with a milli-volt
meter having a 0-1000 mV range. Conduct
each check shown in chart below by con-
nection meter test leads to terminals as
indicated.
A. COMPLETE MILLIVOLT SYSTEM CHECK
("A" Reading - Thermostat contacts CLOSED - Control Knob "ON" - Main burner should turn ON)
a. If the reading is more than 100 milli-volts and the automatic valve still does not come on, replace the control.
b. If the closed circuit reading ("A" reading) is less than 100 millivolts, determine cause for low reading, proceed to
Section B below.
B. Thermopile Output Reading Check
("B" Reading - Thermostat contacts OPEN - Main burner OFF)
1. Check gas pressure to the unit. If gas pressure is within minimum and maximum on data plate, then check pilot
voltage, 325 millivolts minimum. If the minimum milli-volt reading is not obtainable, replace pilot.
