that are used for installing the gas control. After the adapter 

is installed,  the gas control is attached to the adapter as 

outlined above. Note that using an adapter increases the 

overall length of the gas control. 

CHOOSE GAS CONTROL LOCATION 

Do not locate the gas control where it may be affected 

by steam cleaning, high humidity, dripping water, corrosive 

chemicals,  dust  or  grease  accumulation,  or  excessive 

heat. To ensure proper operation, follow these guidelines. 

• Locate gas control in a well ventilated area.

• Mount gas control high enough above the cabinet

bottom to avoid  exposure to flooding or splashing

water. 

• Ensure the ambient temperature does not exceed

the ambient temperature ratings for each compo­

nent.

• Cover gas control if appliance is cleaned with water,

steam,  or chemicals  or  to  avoid dust  and  grease

accumulation.

• Avoid locating gas control where exposure to cor­

rosive chemical fumes or dripping water are likely.

Locate the gas control in the appliance vestibule on the 

gas manifold. In replacement applications, locate the gas 

control in the same location as the old gas control. 

Install Piping to Gas Control 

All piping must comply with local codes and ordinances 

or with the National Fuel Gas Code (ANSI Z223.1 NFPA 

No. 54), whichever applies. Tubing installation must comply 

with approved standards and practices. 

1. Use new,  properly  reamed pipe free from chips.  If

tubing is used, ensure the ends are square, deburred and 

clean.  All  tubing  bends  must  be  smooth  and  without 

deformation. 

2. Run pipe or tubing to the gas control. If tubing is used,

obtain a tube-to-pipe coupling to connect the tubing to the 

gas control. 

3. Install  sediment  trap  in  the  supply  line  to  the  gas

control. See Fig. 3. 

Install Gas Control 

1. 

Mount the gas control 

0-90 

degrees, in any direction,

from the upright position of the gas control knob, including 

vertically. 

2. Mount the gas control so gas flow is in the direction

of the arrow on the bottom of the gas control. 

3. Thread pipe the amount shown in Table 4 for inser­

tion into the gas control  or adapter.  DO NOT  THREAD 

PIPE TOO FAR. Valve distortion or malfunction may result 

if the pipe is inserted too deeply into the gas control.
