11. Turn the knob on the pilot valve to on, Figure 18.
12. Turn the knob on the main gas valve to on, 300 and 400 models, 

Figure 18. On 600 through 2100 models open the manual shutoff 

valve located in the control compartment, Figure 19.

13. Turn on all electric power to the boiler.

14. Set the staging control or thermostat to the desired setting.
15. The pilot should automatically light. Do not try to light the pilot 

by hand!

16. The burners should light with proper boiler operation.
17. The pilot and manifold pressures should match those listed  

in Table 19. To adjust the manifold gas pressure see the “Gas 

Pressure Adjustment” instructions in the “CHECKING AND 

ADJUSTMENTS” section.

Required Gas Pressure

Provide gas supply pressure at inlet to boiler gas train as follows:

    LP 

 

Nat

 

Minimum (in WC)  

11  

 7

 

Maximum (in WC)  

14  

14

Measure pressure when the boiler is firing at full rate. Low gas pressure 

could indicate undersized gas line or insufficient gas supply.
"Static and operating gas pressure required at the gas valve inlet is 

between 7 in WC and 14 in WC for natural gas and 11 in WC  and 

14 in WC  for propane. If the gas pressure is above this limit, a lock-up 

style regulator suitable for dead end service such as an Equimeter  

or Fisher must be installed to prevent increase (creep) of gas pressure 

when the units are not operating. This pressure regulator (supplied 

by others) may be installed at the service entrance to each unit or  

a "master" regulator sized to handle multiple units may be utilized. 

Consult local gas utility or regulator manufacturer for recommenda-

tions to meet specific job site requirements."

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 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 valves.

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.
