Hotshot Gas Fireplace Insert
XG0511 - 150203
Installation
Installing The Gas Line
The gas line must be installed before finishing the Hotshot DHS insert.
For ease of installation, this appliance is equipped with an approved
flexible gas connector. The connector is factory-installed and can be
connected to the gas line as shown in figure 3.
Natural Gas requires a minimum inlet gas supply pressure of 5.5"
W.C. & a manifold pressure of 3.5" W.C. Propane Gas requires a
minimum inlet gas supply pressure of 11" W.C. & a manifold pressure
of 10" W.C. The fireplace gas connection and the main operating gas
valve is located behind the removable brass trim at the bottom of the
unit and need only be attached to the gas line with an approved fit-
ting, as required by the applicable installation codes.
• Only use gas shut-off valves approved for use by the state, province,
region, or governing body, in which the appliance is being installed, or
as required by the applicable installation codes.
The appliance and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any pressure testing
of the gas supply piping system at test pressures equal to or less than
1/2 psig (3.5 kPa).

Note: After the gas line is connected, each appliance con-
nection, valve and valve train must be checked while
under normal operating pressure with either a liquid
solution, or leak detection device, to locate any source
of leak. Tighten any areas where bubbling appears or
leak is detected until bubbling stops completely or leak
is no longer detected. DO NOT use a flame of any
kind to test for leaks.
