4 .  Thread replacement gas orifices into gas manifold . To prevent cross-threading, hand-tighten orifices into gas 

manifold until snug and then tighten one-half to one turn using wrench .

⚠ DANGER ⚠

DO NOT use an open flame to check for gas leaks.

5 .  Check all connections for gas leaks using commercial leak-detecting fluid or rich soap and water solution . Leaks 

are indicated by presence of bubbles . If leak is detected, tighten connection . If leak cannot be stopped by tightening 

connection, replace part(s) .

Conversion to LP (Propane)

⚠ DANGER ⚠

Conversion to LP (propane) gas must be performed by qualified service personnel using a factory-

supplied conversion kit. Failure to use the proper conversion kit can cause fire, explosion, property 

damage, carbon monoxide poisoning, personal injury, or death.

If LP (propane) conversion is required, convert the unit in accordance with form 

OPT-GC

 listed in 

Table 1

 . When 

conversion is complete, verify that the input rate is correct .

Dirty Filter Switch Adjustment

After the unit is started but before continuous operation, the dirty filter switch must be set as follows:
1 .  With clean filters in place, blower doors closed, and blower operating, decrease pressure setting by adjusting 

setscrew on switch (see 

Figure 46

) clockwise until indicator light is energized or setscrew is bottomed out .

2 .  At that point, adjust setscrew three full turns counterclockwise or until setscrew is top-ended .
3 .  At that setpoint, indicator light will be activated at approximately 50% filter blockage .
