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.

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.

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.
