INSTALLATION
Gas Line Hook-Up (Cont.)
In conformance with local codes, route a 1/2" NPT gas line
towards the appliance coming in from any of the 3 directions
shown in Figure 16.
DESA recommends that a black iron gas line be routed from the gas
source, through a sediment trap (shown in Figure 17), and into the
appliance, Once connected through the appliance, a flexible gas line
may be used for ease of installation to gas control valve (see Figure 18).
Before connecting the black iron gas line to the inside of the appliance
a sediment trap must be included outside the appliance between the gas
line and the gas shutoff valve. It must extend down three (3) inches
beyond the center of the pipe. Prepare incoming black iron gas line with
teflon tape or pipe joint compound (Check with local building codes).
Figure 18 - Connecting Flexible Gas Line to Millivolt Valve
WARNING: All gas piping and connections must
be tested for leaks after the installation is completed.
After ensuring that the gas valve is on, apply a noncor-
rosive leak detection fluid to all connections and joints.
If bubbles appear, leaks can be detected and corrected.
Do not use an open flame for leak testing and do not
operate any appliance if a leak is detected.
Complete your gas installation by connecting incoming gas line
with flexible gas line. Secure tightly with wrench but DO NOT
OVERTIGHTEN.
CAUTION: Compounds used on threaded joints
of gas piping shall be resistant to the action of
Liquefied Petroleum (LP or propane), and should be
applied lightly to ensure excess sealant does not
enter the gas line.
