OUTLET PRESSURE ADJUSTMENT
1.  Turn off all electrical power to the system.
2.  Remove plug and install hose barb fitting and manometer 

to pressure tap on outlet end of valve. See fig. 5.

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 (fig. 5) and turn 
screw clockwise (

) to increase pressure, or coun-

terclockwise (

) to decrease pressure. Always adjust 

regulator according to original equipment manufacture’s 
specifications listed on the appliance 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 (fig. 5) and turn 
screw clockwise (

) to increase pressure, or coun-

terclockwise (

) to decrease pressure. Always adjust 

regulator according to original equipment manufacturer’s 
specifications listed on the appliance rating plate. Replace 
regulator cover screw.

7.  Turn off all electrical power to the system.
8.  Remove manometer hose and fitting 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 soapsuds, check for 

leaks at pressure tap plug. Bubbles forming indicate a leak. 
SHUT OFF GAS AND FIx ALL LEAkS IMMEDIATELY. 

(Models 36H3x and 36H6x only)

If the pilot frame is low and does not engulf the bulb of the 
mercury flame 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 flame to lift off the burner, causing the 
flame sensor bulb to sense “low” heat.
To adjust the pilot gas pressure, remove the cover screw (See 
fig. 5). 

To REDUCE pilot pressure, turn the pilot adjust screw 

(beneath the cover screw) clockwise (

) . 

pilot pressure, turn the pilot adjust screw counterclockwise (

). Replace and tighten cover screw.

For gas to gas conversion, consult your dealer for appropriate 
conversion kit.
