24 “ Vented Gas Log
Model: GLDF24M-V
Dual Fuel
Adjustable temperature settings determine the length of time that
the heater will operate at maximum BTU to achieve desired temperature,
not the actual flame height.
During first seasonal use, gas smell is expected to be more noticeable than in
standard operation.
Operation Notes:
To stop the heater, shut off the safety valve on the gas inlet line. Then,
turn the heater’s Gas Valve Button to the OFF position.
Shutdown Process:
5. The heater will now operate normally. Room temperature will vary
based on individual room size and installation.
4. Once the pilot flame is stable, slightly push the Control Knob down
while turning from the Pilot setting to the Burner position . This
should be done slowly in one motion, without stopping between
positions.
3. Release both buttons. Should the pilot go out, repeat steps 2 and 3.
2. While continuing to keep the Control Knob pushed in, also push
down on the Igniter Button thoroughly until ignition can be heard.
Continue to hold down both buttons for at least 15 seconds, until the
pilot is touching the thermocouple and is noticeably heated.
1. During the first seasonal operation, set the Control Knob to Pilot, then
hold down on the Control Knob for 3-5 minutes. This allows the air in
the manifests to clear completely. During normal operation, you will
only need to hold the Control Knob down on Pilot for about 5 seconds.
Ignition Process:
Follow these steps to ensure that your heater
is running the right way, every time.
