GENERAL INFORMATION
Approved Vent Components
These fireplaces are designed, tested, and listed
for operation and installation with the following
vent components (8" inner and 11" outer) only:

These appliances are designed to operate on
natural or propane gas only. The use of other
fuels or combination of fuels will degrade the per
-
formance of this system and may be dangerous.
These models come standard with a remotely
modulated gas valve. The included transmitter
remotely controls flame appearance and heat
output (manual gas valve adjustment is not
possible).

INTRODUCTION
These See-Through appliances are direct-vent,
sealed combustion gas fireplaces designed
for either
indoor/indoor
or
indoor/outdoor
residential applications (including screened
porches and lanais). See “
Minimum Clearances
to Combustibles
” on
Page 11.
NOTE: INDOOR/OUTDOOR INSTALLATIONS
REQUIRE AN OUTDOOR INSTALLATION KIT
(SOLD SEPARATELY).
These appliances are designed to operate on
natural or propane gas. The system is switch-
able between standing and intermittent pilot
modes.
External electrical power is required to operate
these units. In the event of a power outage,
four “AA” batteries (in receiver) can be used
as a backup.

ments for these appliances are listed in

Test gauge connections are provided on the front
of the electronic gas control valve (identified
IN
for the inlet and
OUT
for the manifold side).
The control valves have a 3/8" (10 mm) NPT
thread inlet and outlet side of the valve. Refer
to
Figure 1
.
Propane tanks are at pressures that will cause
damage to valve components. Verify that the
tanks have step-down regulators to reduce the
pressure to safe levels.
