REMOVE LOW GAS PRESSURE SWITCH

NOTE: 

Remove  the  Low  Gas  Pressure  Switch  before  installing  the

manifold on the burner assembly.

NOTE: 

There are two ways that the Low Gas Pressure Switch (LGPS)

could  have  been  installed  during  the  original  natural  to  Propane  gas

conversion.

All 14 3/16-in Casings or Vent Passed Between Inducer 

Assembly and Burner Assembly

If the vent pipe passes between the inducer and burner assembly, or the

furnace is a 14 3/16-in. wide casing. The switch is installed as shown in

Fig. 18

.

1. Remove low gas pressure switch, brass street 90_ elbow, brass hex

nipple, brass tee and black iron street 90_ elbow from the gas valve

inlet pressure tap, see 

Fig. 18

.

NOTE: 

Use pipe dope approved for use with Propane gas. DO NOT use

PTFE thread-seal tape.

2. Apply  pipe  dope  sparingly  to  the  1/8-in.  (3  mm)  NPT  pipe  plug

(provided in kit) and install in the 1/8-in tapped inlet-pressure tap

opening  in  the  gas  valve.  DO  NOT  over-tighten.  Check  for  gas

leaks after gas supply has been turned on.

inducer and burner assembly

Casings Wider Than 14 3/16-in/Vent Does Not Pass 

Between Inducer and Burner Assembly

If the vent pipe does not pass between the inducer and burner assembly,

or  the  furnace  is  wider than  a 14  3/16-in.  wide  casing. The  switch  is

installed as shown in 

Fig. 19

.

1. Remove Low Gas Pressure Switch (LGPS), brass street tee, brass

nipple and brass street 90° elbow from the gas valve inlet  pressure

tap, see 

Fig. 19

.

NOTE: 

Use pipe dope approved for use with Propane gas. DO NOT use

PTFE thread-seal tape.

2. Apply  pipe  dope  sparingly  to  the  1/8-in.  (3  mm)  NPT  pipe  plug

(provided  in  kit)  and  install  in  the  1/8-in  (3  mm)  tapped

inlet-pressure tap opening in the gas valve. DO NOT over-tighten.

Check for gas leaks after gas supply has been turned on.

Fig. 19 – LGPS for casing wider than 14-3/16 and vent does not pass 

between inducer and burner assembly

INSTALL MANIFOLD

1. Refer to 

Fig. 2

 and 

Fig. 3

.

2. Align the orifices in the manifold assembly with the support rings

on the end of the burner.

3. Insert  the  orifices  in  the  support  rings  of  the  burners.  Manifold

mounting tabs should fit flush against the burner box.

NOTE: 

If manifold does not fit flush against the burner box, the burners

are  not  fully  seated  forward.  Remove  the  manifold  and  check  burner

positioning in the burner box assembly.

4. Attach  the  green/yellow  wire  and  ground  terminal  to  one  of  the

manifold mounting screws, see 

Fig. 2

WARNING

!

FIRE OR EXPLOSION HAZARD

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

and/or property damage. 

Never  test  for  gas  leaks  with  an  open  flame.  Use  a  commercially

available soap solution made specifically for the detection of leaks to

check all connections. A fire or explosion may result causing property

damage, personal injury or loss of life.

AVERTISSEMENT

!

RISQUE D’EXPLOSION ET D’INCENDIE

Le non-respect des avertissements de sécurité pourrait d’entraîner des

blessures graves, la mort ou des dommages matériels.

Ne jamais utiliser une flamme nue por vérifier la présence des fuites de

gaz. Pour la vérification de tous les joints, utiliser plutôt une solution

savonneuse commerciale fabriquée spécifiquement pur la détection des

fuites  de  gaz.  Un  incendie  ou  une  explosion  peut  entraîner  des

dommages matériels, des blessures ou la mort.
