LES SYSTÈMES À EAU CHAUDE NE DOIVENT PAS
ÊTRE SOUMIS À UNE PRESSION DÉPASSANT
30 LIVRES, À MOINS QUE LA CHAUDIÈRE SOIT
CONÇUE SPÉCIALEMENT POUR UNE PRESSION
DE FONCTIONNEMENT PLUS ÉLEVÉE. SI LA
PRESSION INTERNE DE LA CHAUDIÈRE DÉPASSE
LA PRESSION PARAMÉTRÉE DE LA SOUPAPE DE
SÛRETÉ, CETTE DERNIÈRE RELÂCHERA DE LA
PRESSION IMMÉDIATEMENT, MAIS LA CAUSE DE
CETTE DÉCOMPRESSION DOIT ÊTRE EXAMINÉE
ET CORRIGÉE. LA PRESSION EXCESSIVE EST
DANGEREUSE. DE PLUS, ELLE POURRAIT
ENDOMMAGER LE SYSTÈME DE CHAUFFAGE OU
CAUSER DES BLESSURES OU DES DOMMAGES
MATÉRIELS SÉRIEUX.
NE PAS soutirer de l’eau de la chaudière lorsque
celle-ci est en marche. Si la chaudière fonctionne, ne
pas y ajouter de l’eau en ouvrant complètement la vanne
d’alimentation; ajouter l’eau lentement.
3. BURNER
A.
Check wiring of all fuel valves. Verify that wiring
is correct according to the factory supplied wiring
diagram.
B.
Leave all manual fuel valves closed. This includes
manual shutoff valves supplied with the boiler and
facility installed valves at the boiler site.
C.
Perform all burner pre-startup checks according
to the burner manufacturer's specifications. Refer
to the burner manufacturer's installation manual
furnished with the boiler.
D.
Turn boiler on and verify that fuel valves are
closed during the burner pre-purge cycle. Turn
boiler off and disconnect power.
E.
Adjust burner according to the burner
manufacturer's specifications. Target CO
2
level
is 13% for optimum efficiency, but a range of
12.5-13.0% is acceptable.
4. TEST CONTROLS
Before installation of the boiler is considered complete
the operation of the boiler controls should be checked,
particularly the low water cutoff and the high limit
control.
Avant que l’installation de la chaudière soit considérée
comme terminée, vérifier le fonctionnement de ses
dispositifs de contrôle, en particulier les interrupteurs
à bas niveau d’eau et le contrôleur de température
maximale.
1.
ALWAYS INSPECT INSTALLATION BEFORE
STARTING BURNER.
2. FILL HEATING SYSTEM WITH WATER.
Any time that raw water is introduced to the boiler
it must be heated to at least 180ºF immediately to
dissipate the dissolved gases which can otherwise
cause internal corrosion to the boiler.
Chaque fois que de l’eau non traitée est introduite
dans la chaudière, il faut immédiatement la chauffer
jusqu’à 100°C (180°F) pour dissiper les gaz dissous qui,
autrement, pourraient provoquer de la corrosion interne.
A. Steam Boilers
Fill boiler to normal water line.
Water should be visible in the gauge glass.
After boiler is in operation, make up water should
be added slowly to maintain the water level.
B.
Hot Water Boilers
In a hot water heating
system, the boiler and the entire system
(other than the tank) must be full of water for
satisfactory operation. Water should be added
to the system until the boiler pressure gauge
registers normal system design operating
pressure. To ensure that the system is full, water
should come out of all air vents when opened.
ON A HOT WATER SYSTEM THE PRESSURE MUST
NOT EXCEED 30 POUNDS UNLESS THE BOILER IS
ESPECIALLY DESIGNED FOR A HIGHER MAXIMUM
WORKING PRESSURE. IF A BOILER PRESSURE EXCEEDS
PRESSURE SETTING OF SAFETY RELIEF VALVE, VALVE
WILL RELIEVE IMMEDIATELY, BUT CAUSE OF RELIEF
MUST BE INVESTIGATED AND CORRECTED. EXCESS
PRESSURE IS DANGEROUS, IN ADDITION, COULD CAUSE
DAMAGE TO HEATING SYSTEM, PERSONAL INJURY OR
SERIOUS PROPERTY DAMAGE.
DO NOT draw water from the boiler while in use. When
adding water while boiler is in operation, do not open
the supply valve fully, but add water slowly.
