Emerson White-Rodgers 36H Series User manual

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
The 36H series combination gas valve has redundant
and main solenoid valves that control gas ow to the
main burners, a pressure regulator to maintain a con-
stant outlet pressure, and a two position on/o switch
for electrical shuto. The valves are shipped from the
factory set for natural gas non-piloted applications.
See instructions in this document for modications
required if the valve is to be installed on an LP gas
and/or piloted gas application.

INSTALLATION
MAIN PIPING CONNECTIONS
NOTE
Refer to warnings and cautions on page 3 before
attempting installation. All piping must comply
with local codes, ordinances, and/or national fuel
gas codes.
1. Turn o electrical power to the system at the fuse
box or circuit breaker. Also turn o the main gas
supply.
2. If replacing an existing valve, disconnect all
plumbing and electrical connections from the
old control.
3. Thisvalvemaybeinstalledupright,+or–90˚from
upright, or vertical (refer to g. 1). The arrows on
the valve identication label and on the bottom
plate indicate direction of gas ow through the
valve.
4. You should use new pipe that is properly cham-
fered, reamed, and free of burrs and chips. If
you are using old pipe, be sure it is clean and
free of rust, scale, burrs, chips, and old pipe joint
compound.
5. Apply pipe joint compound (pipe dope) or teon
tape that is approved for all gases, only to the
male threads of the pipe joints. DO NOTapply
compound or teon tape to the rst two threads
(see g. 3 for typical piping connections).
6. Do not tighten piping excessively, as this may
damage the valve (50 ft lbs max).
7. See SYSTEM WIRING when making electrical
connections. After all gas and electrical connec-
tions are completed, turn gas on and check for
gas leaks with leak detection solution or soap
suds. Bubbles forming indicate a leak. SHUT
OFF GAS AND FIX ALL LEAKS IMMEDIATELY.
LP GAS CONVERSION
For LP gas conversion, use the LP conversion kit
supplied with this control. Refer to the instruc-
tions packed with LP conversion kit.
PILOT GAS CONNECTION
These gas valves are shipped with the pilot outlet
plugged. For installations requiring pilot gas
(Proven/Intermittent Pilot Systems), remove the
plug from the pilot gas outlet (see g. 2) and use
the tting packed separately with the valve.
Install the tting into the pilot gas outlet, turning
until nger tight. Insert clean, de-burred 1/4" O.D.
tubing all the way through the tting. While hold-
ing the tubing securely, slowly tighten the tting
until you feel a slight “give”. Tighten the tting 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 page 7 for pilot ame adjustment infor-
mation.
Allpipingmustcomplywithlocalcodes,ordinances,
and/or national fuel gas codes.

SYSTEM WIRING
REFERTOAND FOLLOWTHEAPPLIANCEMAN-
UFACTURER’S WIRING DIAGRAM. REFER TO
FIG. 4 AND 5 FOR TERMINAL IDENTIFICATION.
These valves are shipped with an external jumper
installed for non-piloted gas applications.
• For non-piloted gas applications HSI and DSI,
connect common wire to (C) terminal and hot
wire to external jumper (MP) terminal
(see g. 4and 5).
NOTE
All wiring should be installed in accordance with local and national electrical codes and ordinances.
Always check that the electrical power supply used agrees with the voltage and frequency shown on
the gas control.

OUTLET PRESSURE ADJUSTMENT
1. Turn o all electrical power to the system.
2. Remove plug and install hose barb tting and
manometer to pressure tap on outlet end of
valve. See g. 9.
3. Turn on system power. Set thermostat to call
for heat (low stage for two-stage systems).
Main burner should light. Proceed to step 6 for
single stage systems.
4. (2-stage only) Remove regulator cover screw
from the low outlet pressure regulator adjust
tower (g. 9) and turn screw clockwise ( )
to increase pressure, or counterclockwise
( ) to decrease pressure. Always adjust
regulator according to original equipment
manufacture’s specications listed on the ap-
pliance rating plate. Replace regulator cover
screw.
5. (2-stage only) Set thermostat to call for high
stage.
6. Remove regulator cover screw from the single
stage or high outlet pressure regulator adjust
tower (g. 9) and turn screw clockwise ( )
to increase pressure, or counterclockwise
( ) to decrease pressure. Always adjust
regulator according to original equipment
manufacturer’s specications listed on the
appliance rating plate. Replace regulator cover
screw.
7. Turn o all electrical power to the system.
8. Remove manometer hose and tting from
outlet pressure tap.
9. Replace outlet pressure tap plug and tighten
(clockwise 40-60 in-lb.)
10. Turn on system power and set thermostat to
call for heat.
11. Using a leak detection solution or soap suds,
check for leaks at pressure tap plug. Bubbles
forming indicate a leak. SHUT OFF GAS AND
FIX ALL LEAKS IMMEDIATELY.
PILOT FLAME ADJUSTMENT
If the pilot ame is low and does not engulf the
ame sensor, the system will not energize the
main valve. If pilot gas pressure is too high, gas
will sputter past the ignition electrode, and may
not ignite. High pilot gas pressure may also cause
the ame to lift o the burner, causing the ame
sensor to sense “low” heat.
To adjust the pilot gas pressure, remove the cover
screw (See g. 9). To REDUCE pilot pressure,
turn the pilot adjust screw (beneath the cover
screw) clockwise ( ) . To INCREASE pilot
pressure, turn the pilot adjust screw counterclock-
wise ( ). Replace and tighten cover screw.
ADJUSTMENT
PRESSURE REGULATOR
ADJUSTMENT
These controls are shipped from the factory with
the regulator set as specied on the control label.
Consult the appliance rating plate to ensure burner
manifold pressure is as specied. If another outlet
pressure is required, follow these steps.
NOTE
NaturalGas:Two-StageModels- Low outlet pres-
sure can be adjusted in the 1to 3.5” W.C. range and
high outlet pressure can be adjusted in the 2.5 to 5”
range. The valve cannot be adjusted outside this
range and the high outlet pressure setting must
always be set at least 1.5” above the low outlet
pressure setting.
Single Stage Models - Outlet pressure can be ad-
justed in the 2.5” to 5” range. The valve cannot be
adjusted outside this range.

A. HSI MODELS:This appliance does not have a
pilot. It is equipped with an ignition device which
automatically lights the burner. Do not try to
light the burner by hand.
PROVEN/INTERMITTENT PILOT MODELS:
This appliance is equipped with an intermittent
ignition device which automatically lights the
appliance. Do not try to light the pilot by hand.
B. BEFORE OPERATING smell all around the ap-
pliance area for gas. Be sure to smell next to the
oor because some gas is heavier than air and
will settle on the oor.
