Millivolt Safety Pilot Valve (Fig. 16-1)
The valve regulator controls the burner pressure which
should be checked at the pressure inlet point.Turn
the inlet screw counter-clockwise 2 or 3 turns and
then place the tubing of the pressure gauge over the
pressure inlet point. (The test inlet point is closest to
the gas supply inlet.) After taking the pressure reading,
be sure to turn the inlet screw clockwise fi rmly to
reseal. Do not over torque. Check for gas leaks.

WARNING
Do not connect this appliance directly to a high pressure natural gas line or an unregulated L.P. tank.
CHECKING GAS PRESSURE
The gas log set and its main gas valve must be disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of
1
/
2
psig. The gas log set must be isolated from
the gas supply piping system by closing its equipment shut-off valve during any pressure testing of the gas
supply piping system at test pressures equal to or less than
1
/
2
psig. This is accomplished by closing the gas
supply line valve.
