Installation Instructions (cont'd)

4. Leak Test the Gas Connections and Test

the Gas Pressure

If the unit has a gas train that includes an

inlet manual shutoff valve, close the valve.

If the gas train does not include a manual

shutoff valve before the main control valve,

disconnect and cap the gas line.

WARNING: All components of a
gas supply system must be leak
tested prior to placing equipment
in service. NEVER TEST WITH
AN OPEN FLAME.

High pressure testing of supply lines
is acceptable, provided the supply line
has been disconnected from the unit
and the pipe end capped.

Connect a manometer to the outlet pressure

tap.
Turn on the gas supply and leak test the regu-

lator connections. Test using a leak-detect-

ing solution.
Check the gas pressure reading on the ma-

nometer. Outlet gas pressure must not be

greater than 1/2 psi (14" w.c.). Outlet gas

pressure may be adjusted between 4" w.c.

and 12" w.c. at the regulator.

3. Install Vent Line (See Figure 1)

Remove the plastic plug from the tapped vent in the top of the regulator. Start-

ing at the regulator (tapped vent) install the vent line by connecting the pieces

of pipe in the following sequence:

Black Iron Hex Bushing

Outdoor Installation

- Attach plastic bug screen.

Indoor Installation

- Extend vent line outdoors using 1/8" field-supplied pip-

ing; attach bug screen to outdoor end of the vent line.

Figure 1- Install vent

line on the gas

regulator in the

sequence and direction

illustrated (If indoor

installation, vent line

must be field extended

to the outdoors.)
