Emerson White-Rodgers 36H32 Serie Manual De Instrucciones

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE
INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL
INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
The 36H universal gas valves are designed for use on automatic
spark ignition systems. The valves are shipped from the factory
set for natural gas non-piloted applications. See the Installation
Instructions included with the valves for proper installation.
This document shows the modifications required if the valve is
to be installed on an LP gas and/or piloted gas application.
LP GAS CONVERSION
For LP gas conversion, use the LP conversion kit supplied
separately with this control. Refer to the instructions packed
separately with LP conversion kit.
PILOTED GAS APPLICATIONS
WIRING
These valves are shipped with an external wire jumper installed
for non-piloted gas applications. For applications requiring piloted
gas, such as intermittent pilot or spark-to-pilot systems, remove
the external wire jumper from the main (M) and pilot (P) valve
terminals (see figure 1).

PILOT GAS CONNECTION
These gas valves are shipped with the pilot outlet plugged. For
installations requiring pilot gas, remove the plug from the pilot
gas outlet (see figure 2) and use the fitting packed separately
with the valve.
Install the fitting into the pilot gas outlet, turning until finger tight.
Insert clean, de-burred ¼" O.D. tubing all the way through the
fitting. While holding the tubing securely, slowly tighten the fit-
ting until you feel a slight "give". Tighten the fitting an additional
1-1/2 turns.
(+)
The plug should not be removed for a Direct Burner Ignition
system such as Direct Spark or Hot Surface Ignition.
Refer to the 36H Series Installation Instructions for pilot flame
adjustment information.
