Note:

 Never use plastic pipe. Check to confirm whether your local 

codes allow copper tubing or galvanized.

Note: 

Since some municipalities have additional local codes, it is 

always best to consult your local authority and installation code.
Check all local codes for requirements, especially for the size and 

type of gas supply line required.  On Natural gas lines less than 15' 

(4.57m) long, use 1/2" pipe; on longer runs,  use 3/4" iron pipe or 

equal.  On  LP gas lines please consult LP gas supplier.

Installing a New Main Gas Cock

Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of the unit. 

Where none exists, or where its size or location is not adequate, 

contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant 

to the action of liquefied petroleum gases. The gas lines must be 

checked for leaks by the installer. This should be done with a soap 

solution watching for bubbles on all exposed connections, and if 

unexposed, a pressure test should be made. 

Never use an exposed flame to check for leaks. Appliance must 

be disconnected from piping at inlet of control valve  and pipe 

capped or plugged for pressure test. Never pressure test with 

appliance connected; control valve will sustain damage!

A gas valve and ground joint union should be installed in the gas 

line upstream of the gas control to aid in servicing. It is required by 

the National Fuel Gas Code that a drip line be installed near the gas 

inlet. This should consist of a vertical length of pipe tee connected 

into the gas line that is capped on the bottom in which condensation 

and foreign particles may collect. 

Figure 1

The use of the following gas connectors is recommended:

—  ANS Z21.24 Appliance Connectors of Corrugated Metal Tubing 

and Fittings

—  ANS Z21.45 Assembled Flexible Appliance Connectors of Other 

Than All-Metal Construction

The above connectors may be used if acceptable by the authority 

having jurisdiction. The state of Massachusetts requires that a 

flexible appliance connector cannot exceed three feet in length.

Pressure Testing of the Gas Supply System

1.  To check the inlet pressure to the gas valve, a 1/8" (3.175mm) 

N.P.T. plugged tapping, accessible for test gauge connection,  

must be placed immediately upstream of the gas supply 

connection to the appliance.

2.   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).

3.   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).

Attention! 

 If one of the procedures results in pressures in excess 

of 1/2 psig (14" w.c.) (3.5 kPa) on the appliance gas valve, it will 

result in a hazardous condition.

Checking Manifold Pressure

Both Propane and Natural gas valves have a built-in pressure 

regulator in the gas valve.  Natural gas models will have a manifold 

pressure of approximately 3.5" w.c. (.871kPa) at the valve outlet 

with the inlet pressure to the valve from a minimum of 4.5" w.c. 

(1.120kPa) for the purpose of input adjustment to a maximum of 

10.5" w.c. (2.614kPa)   Propane gas models will have a manifold 

pressure approximately 10.0"  w.c. (2.49kPa) at the valve outlet 

with the inlet pressure to the valve from a minimum of 11.0" w.c. 

(2.739kPa) for the purpose of input adjustment to a maximum of 

13.0" w.c. (3.237kPa).  
A 1/8" (3.175mm) N.P.T. plugged tapping, accessible for test gauge 

connection, is located on the outlet side of the gas control.
