GAS CONNECTION
For minimum and maximum supply pressure
see the System Data table on page 7.
Note: Prior to any pressure testing of the
gas supply piping system that ex-
ceeds test pressures of 1/2 psig, this
appliance and its individual shut-off
valve must be disconnected from
the piping system. If test pressures
equal to or less than 1/2 psig are used
then this appliance must be isolated
from the piping system by closing
its individual manual shut-off valve
during the testing.
Valve Access: Loosen and remove the wing-
nuts on the both sides of the bottom louver and
then remove the louver.
GAS CONNECTION WARNING:
2) The gas connection is a 3/8" NPT male pipe
on the rear left side of the unit. The gas line
can be rigid pipe or to make installation
easier use a listed fl exible connector and
manual shut-off valve if allowed by local
building codes. A 1/2" gas supply pipe must
be brought near this inlet hole.
3) Locate the center point where the vent will
pass through the chimney above the appli-
ance. Move the appliance into the exact
location where it is to be installed. Ensure
that the Insert is level.
4) The gas control valve is provided with two
"IN" and "OUT" pressure taps, and are easily
accessible for a test gauge connection (see
diagram on page 9).
5) Once the gas has been connected ensure
that the pilot valve is in line with burner.
CAUTION: If the door is removed or opened
for servicing, it must be replaced and closed
prior to operating the appliance. The glass
must be fi xed in the door when operating.

There must be at least 3 feet of chimney above
the roof level.
Stack the pipe onto your fi nish support to a
minimum height of 3 feet above the roof pen-
etration, or 2 feet above any point within 10 feet

with the guides on the insert top and push
forward. While pushing the unit back into
place keep pulling the draft hood forward until

screw holes do not line up then draft hood
is not positioned correctly.) Secure the two
spill tubes with a screw.
Note: Final gas connection should be after
unit is in place to avoid damage to line
when pushing the unit
into position.
