AGAGC9PNS01B Gas Conversion Kit, Propane to Natural: Installation Instructions

Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

5. Install the remaining manifold mounting screws.
6. Connect the wires to the flame sensor and hot surface igniter.
7. Connect the connector harness to gas valve.

NOTE: 

Do not use PTFE thread-seal tape.

8. Insert the gas pipe through the grommet in the casing. Apply a thin

layer of pipe dope to the threads of the pipe and thread the pipe by

into the gas valve.

NOTE: 

Use  a  back-up  wrench  on  the  gas  valve  to  prevent  the  valve

from rotating on the manifold or damaging the mounting to the burner

box.

9. With  a  back-up  wrench on the inlet boss of  the  gas valve, finish

tightening the gas pipe to the gas valve.

10. Turn gas on at electric switch on gas valve.

CHECK INLET GAS PRESSURE

NOTE: 

This kit is to be used only when inlet gas pressure is between

4.5-in. w.c. and 13.6-in. w.c.

1. On  some  models,  remove  1/8-in.  (3  mm)  pipe  plug  from  inlet

pressure tap (see 

Fig. 18

 and 

Fig. 19

) and insert pressure tap. Or, on

some models, loosen set screw on inlet tower pressure tap no more

than  one  full  turn  with  the  3/32-in.  hex  wrench,  see 

Fig. 11

  or

Fig. 12

.

2. Verify manometer is connected to inlet pressure tap on gas valve,

see 

Fig. 11

 or 

Fig. 12

.

3. Turn on furnace power supply.
4. Turn gas supply manual shutoff valve to ON position.
5. Turn furnace gas valve switch to ON position.

Single Stage Gas Valve

A190022

Fig. 20 – Example of Single Stage Furnace Control

1. Jumper R-W thermostat connections on control.
2. When main  burners  ignite,  confirm inlet  gas  pressure is  between

4.5-in. w.c. and 13.6-in. w.c.

3. Remove  jumper  across  R-W  thermostat  connections  to  terminate

call for heat.

4. Turn furnace gas valve switch to OFF position.
5. Turn gas supply manual shutoff valve to OFF position.
6. Turn off furnace power supply.
7. Remove  manometer  and  on  some  models  remove  pressure  tap

fitting.

8. On some models, apply pipe dope sparingly to end of inlet gas pipe

plug and install into unused end of 1/8-in. (3 mm) tee. Use a small

back-up wrench on tee when tightening gas inlet pipe plug. Or, on

some models, tighten set screw on inlet tower pressure tap with a

3/32-in. hex wrench, see 

Fig. 11

 or 

Fig. 12

.

CAUTION

!

UNIT DAMAGE HAZARD

Failure to follow this caution may result in unit damage.
DO  NOT  operate  furnace  more  than  one  minute  to  check  inlet  gas

pressure, as conversion is not complete at this time.

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.
