Thermostats are not approved on vented decorative appliances.
Label all wires prior to disconnection when servicing controls. Wiring
errors can cause improper and dangerous operation. Verify proper
operation after servicing.
16", 18", 24" and 30" Gas Logs (Millivolt) thermopile is self powered
gas valve and does not require 120 volts. See Figure 25 to provide
optional wall switch, thermostat, or remote control. Maximum
length of 20 feet of 16 AWG to conductor wires is to be used with
all optional switches.
Use the two leads (black wires) from
oN/off
switch to attach
optional components. Output should be a minimum of 325 millivolts
across TH/TP and TP terminals with ON/OFF switch in the OFF
position.
check System operation
Millivolt system and all individual components may be checked with
a millivolt meter 0-1000 MV range.
Remote Receiver -VfSR-(16, 18, 24, 30)
Use the following steps to place the
remote receiver
adjacent to
the gas valve.
Attention:
1. The remote receiver can not be placed behind the gas valve
and burner assembly.
2. When facing the appliance, the remote receiver must be placed
to the
right
of the gas valve and burner assembly.
Notice
:
Do not let remote control receiver come in contact with
burner assembly.
On circulating vent-free firebox, install remote control receiver
behind bottom louver.
Refer to remote control installation and operating instructions for
more details on remote control.
750 Millivolt System
When you ignite the pilot, the thermocouple produces millivolts
(electrical current) which energizes the magnet in the gas valve.
After 30 seconds to 1 minute time period you can release the gas
control knob and the pilot will stay On. Allow your pilot flame to
operate an additional one (1) to two (2) minutes before you turn the
gas control knob from the PILOT position to the ON position. This
time period allows the millivolts (electrical current) to buildup to a
sufficient level allowing the gas control to operate properly.
Millivolt control
The valve regulator controls the burner pressure which should be
checked at the pressure test point. Turn captured screw counter
clockwise 2 or 3 turns and then place tubing to pressure gauge over
test point (Use test point “A” closest to control knob). After taking
pressure reading, be sure and turn captured screw clockwise firmly
to re-seal. Do not over torque. Check for gas leaks.
VfSR
Notice
: (Wiring harness located in envelope)
Connect the 2 - 1/4" terminals onto the TH and TH/TP terminals
on valve. Place decorative log to
right
of the gas valve and burner
assembly. When connecting to remote receiver, cut off 1/4" terminals
from wires attached to ON/OFF switch. Strip wires back about 1/4".
Connect stripped ends into remote receiver.
