Instructions De Mise En Marche
1. ARRÊTEZ! Lisez les instructions de sécurité sur la
portion supérieure de cette étiquette.
2. Réglez le thermostat à la température la plus basse.
3. Coupez l'alimentation électrique de l'appareil.
4. Cet appareil est muni d'un dispositif d'allumage qui
allume automatiquement la veilleuse. Ne tentez pas
d'allumer la veilleuse manuellement.
5. Fermer la vanne manuelle d'arrêt d'alimintation de gaz.
6. Attendre cinq (5) minutes pour laisser échapper tout
le gaz. Reniflez tout autour de l'appareil, y compris
près du plancher, pour déceler une odeur de gaz.
Si vous sentez une odeur de gaz, ARRÊTEZ!
Passez à l'étape B des instructions de sécurité sur
la portion supérieure de cette étiquette. S'il n'y a pas
d'odeur de gaz, passez à l'étape suivante.
7. Ouver la vanne manuelle d'arrêt d'alimintation de gaz.
8. Mettez l'appareil sous tension.
9. Réglez le thermostat à la température désirée.
10. Si l'appareil ne se met pas en marche, suivez les
instructions intitulées «Comment couper l'admission
de gaz de l'appareil» et appelez un technicien
qualifié ou le fournisseur de gaz.
To Turn Off Gas To Appliance
1. Set the operating control or thermostat to its lowest
setting.
2. Turn off all electric power to the appliance if service
is to be performed.
3. Close the manual main and pilot gas shut-off valves.
COMMENT COUPER L'ADMISSION DE GAZ DE
L'APAREIL
1. Réglez le thermostat à la température la plus basse.
2. Coupez l'alimentation électrique de l'appareil s'il faut
procéder à l'entretien.
3. Fermer la vanne manuelle d'arrêt d'alimintation de gaz.
CHECKING & ADJUSTMENT
Pilot Adjustment
The pilot burner flame should envelope 3/8" to 1/2" of
the flame sensing probe, Figure 8. To adjust the pilot
the following steps must be taken:
1. Remove the pilot gas pressure regulator cap.
2. Turn the pressure regulator adjustment screw clock-
wise to increase the flame and counterclockwise to
decrease it.
3. Replace the pressure regulator adjustment screw
cap.

Figure 8 - Pilot Flame Adjustment
Gas Pressure Adjustment
CAUTION: The maximum inlet gas pressure listed on
the rating plate must not be exceeded or damage
to the boiler/water heater may occur!
The minimum supply pressure listed on the rating plate
is for input adjustment.
NATURAL GAS: Optimum results are obtained when the
boiler/water heater is operated at its full input rating, with
3.8" WC to 4.2" WC of manifold pressure. The manifold
pressure should not vary outside this range. The gas
valve pressure regulator has been preset at the factory.
If adjustment is necessary the following steps must be
followed:
1. Attach a 20" manometer to the tap on the manifold.
2. Remove the regulator adjustment screw cap from
the gas regulator. On systems that do not use a
separate gas regulator, remove the adjustment
screw cap from the gas valve body on the valve
closest to the gas supply piping.
3. Rotate the regulator adjustment screw clockwise to
increase the manifold pressure, counterclockwise to
decrease it.
4. Replace the regulator adjustment screw cap and
manifold pressure tap plug.
CAUTION: Never force the regulator adjustment
screw beyond the stop limits or damage to the
regulator will occur!
PROPANE GAS: A manifold pressure of 11" WC must
be maintained for proper operation of the boiler. If the
manifold pressure is off by more than 5% adjust it
according to steps 1 through 4 above.
Input Rate, Natural Gas
Gas appliances are rated based on sea level operation
with no adjustment required at elevations up to 2000
feet. At elevations above 2000 feet, input ratings should
be reduced by 4% for each 1000 feet above sea level.
