WARNING: ANY CHANGE TO THIS HEATER OR ITS
CONTROLS CAN BE DANGEROUS.
Improper installation or use of the heater can cause

Operation
This unvented fireplace requires no outside venting. This unvented
fireplace is designed for vent-free operation with flue damper
closed. State and local codes in some areas prohibit the use of
unvented fireplace.
VFHS-20R 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 clock-
wise firmly to re-seal. Do not over torque. Check for gas leaks.
Millivolt System, VFHS-20R Only
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
build-up to a sufficient level allowing the gas control to operate
properly.
