CONVERT GAS VALVE

NOTE: 

:Do not use this kit if the gas valve in 

Fig. 11

 has a green label

on top of the valve. The green label on the gas valve is a special low

capacity  gas  valve.  Refer  to  Specification  Sheet  for  the  correct

conversion kit.

Single Stage Gas Valve

1. Refer to 

Fig. 5

. Verify the gas valve has a white label with black

lettering on top of the operator.

2. Be sure gas and electrical supplies to furnace are off.
3. Remove  caps  that  conceal  adjustment  screws  for  the  gas-valve

regulators, see 

Fig. 11

 or 

Fig. 12

.

4. Remove the regulator adjustment screw.
5. Remove the propane gas regulator springs (white).
6. Install the natural gas regulator springs (silver).
7. Install the regulator adjustment screws.
8. Turn  the  adjusting  screw  clockwise  (in)  8.5  full  turns. This  will

increase the manifold pressure closer to the natural set point, see

Fig. 11

 or 

Fig. 12

.

9. Do not install regulator seal caps at this time.

NOTE: 

Remove  the  propane  gas  regulator  spring  (white)  Install  the

natural gas regulator spring (silver)

CAUTION

!

UNIT OPERATION HAZARD

Failure to follow this caution may result in unit damage or improper

operation.
DO NOT use this kit if the gas valve has a green label (26,000 BTUH

model) on it. The 26,000 BTUH model uses a different conversion kit

available from your distributor.

CAUTION

!

UNIT DAMAGE HAZARD

Failure to follow this caution may result in unit damage
The gas valve must be converted and pre-adjusted before operating on

propane gas. If not converted and pre-adjusted, sooting and corrosion

will occur leading to early heat exchanger failure.

WARNING

!

FIRE, EXPLOSION, ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury, death or

property damage.

Gas  supply  MUST  be  shut  off  before  disconnecting  electrical  power

and proceeding with conversion.

WARNING

!

ELECTRICAL SHOCK, FIRE OR EXPLOSION HAZARD

Failure to follow this warning could result in personal injury, death or

property damage.

Before  installing,  modifying,  or  servicing  system,  main  electrical

disconnect switch must be in the OFF position and install a lockout tag.

There  may  be  more  than  one  disconnect  switch.  Lock  out  and  tag

switch  with  a  suitable  warning  label.  Verify  proper  operation  after

servicing.
