INTRODUCTION
Models GL36ST/P and GL36STE/EP are decora-
tive gas appliances that use a millivolt gas control
and piezo pilot or an electronic gas control valve
with an electronic ignition system respectively.
These systems require a 6", B-type venting system
for operation.
The 6" B-type vent is not supplied by DESA.
For installation guidelines, check your B-vent
instructions.
WARNING: This gas appli-
ance must not be connected to
a chimney flue servicing a solid
fuel burning appliance.
Models GL36ST and GL36STE are smooth face
units for natural gas only. The GL36STP and
GL36STEP are smooth face units for propane/LP
gas only. To determine which type of gas your unit
is approved and tested for, check the rating plate on
the lift-out plate located inside the firebox under
the access panel.
