OPERATING GUIDELINES
Before operating this heater, please review the safety warnings pages at
the beginning of this manual and those precautions and warnings listed
below.
1. Know what type of ignition system this model has (standing pilot)
and follow the applicable SAFETY and LIGHTING instructions.
2. Check to ensure there are no gas leaks. If you are unsure, turn gas
off to the heater and call a service person or your gas utility.
CAUTION: Clothing or other flammable material should not be placed
on or near the appliance.
WARNING: Children and adults should be alerted to the hazard of high
surface temperature and should stay away to avoid burns or clothing
ignition. Young children should be carefully supervised when they
are in the same room as the appliance.
3. Tampering is DANGEROUS and voids all warranties. Any component
that is found to be faulty, must be replaced with an approved
component.
Initial Lighting (Figure 20)
Upon completing the gas line or turning the gas valve
"ON" after it has
been in the "OFF" position, a small amount of air will be in the lines.
When first lighting the appliance, it will take a few minutes for the lines to
purge themselves of this air. Once the purging is complete, the appliance
will light and operate satisfactorily.
Subsequent lightings of the appliance will not require such purging if the
gas valve is not turned to "OFF."
Standing Pilot Operation
1. Follow the SAFETY and LIGHTING INSTRUCTIONS for standing
pilot controls found in this manual and on labels found attached to
the appliance.
CAUTION: During the initial purging and subsequent lightings, never
allow the gas valve control knob to remain depressed in the "pilot" position
without pushing the piezo ignitor button at least once every second.
2. During the heating season, leave the control valve knob in the "ON"
position. This will allow the pilot flame to remain lit. Turn the burner
flame on or off with the appliance ON/OFF rocker switch, wall switch,
remote control kits or 750 millivolt wall thermostat.
NOTE: The VFCR-25 gas control valve allows you to increase or decrease
the height of the main burner flame. The control valve has a pressure
regulator with a knob as shown in Figure 20. Rotate the knob clockwise
to "HI" to increase the flame height and counterclockwise to "LO" to
decrease the flame height.
3. When the heating season is over, turn the on/off switch to "OFF" and
the control valve to "OFF". The system, including the pilot light, will
be shut down.

Maximum and Minimum Input
The gas valve on the appliance allows the input to adjust between a
maximum input of 25,000 Btuh for Natural gas and Propane gas to a
minimum input of 17,500 Btuh for VFCR-25 and VFCT-25 and 15,000 Btuh
for VFCM-25. The maximum input provides the greatest amount of yellow
flame and ember glow on the log set. The minimum input substantially
decreases the yellow flame and ember glow on the log set.
Warning: Turn off heater and let cool before cleaning.
After use, cleaning of the main burner may be required for the proper
flame. The main burner may be cleaned by applying air pressure to the
ports on the main burner.
Cleaning the Log Set and Firebox
During the annual inspection and maintenance appointment, the service
person should clean dust, lint, and any light accumulation from the logs
and the firebox area. An extra-soft brush should be used on the logs as
they are extremely fragile; a vacuum cleaner may be used on the firebox.
If at any time the logs cannot be removed or installed without forcing,
the cause must be found. The logs must never be forced.
CAUTION: The logs are durable when handled and installed properly.
However, they are delicate and may be damaged easily if not handled
with care. Handling damage to the logs is not covered by warranty.
DO NOT HANDLE LOGS WHILE THEY ARE HOT. ALLOW PLENTY
OF TIME FOR THE APPLIANCE TO COOL COM-PLETELY BEFORE
HANDLING.
Maintenance & Service Instructions
IMPORTANT: Turn off gas before servicing appliance. It is recommended
that a competent service technician perform these check-ups at the
