SECTION IV - OPERATING INSTRUCTIONS
If you do not follow these instructions exactly, a fire
or explosion may result causing property damage
or personal injury.
If any unusual or improper operation or site
conditions are observed, turn the boiler off and
contact an experienced and skilled service agency.
Follow component manufacturer's instructions.
Component manufacturer's instructions were
provided with the boiler. Contact component
manufacturer for replacement if instructions
are missing. Do not install, start up, operate,
maintain or service this boiler without reading and
understanding all of the component instructions.
Do not allow the boiler to operate with altered,
disconnected or jumpered components. Only
use replacement components identical to those
originally supplied with the boiler and burner.
Si vous ne suivez pas ces instructions à la lettre,
un incendie ou une explosion peut en résulter
et entraîner des dommages matériels ou des
blessures corporelles.
Si un fonctionnement inhabituel ou inapproprié
ou des conditions du site sont observés, éteignez
la chaudière et contactez une agence d'entretien
expérimentée et qualifiée.
Suivez les instructions du fabricant des composants.
Les instructions du fabricant des composants
ont été fournies avec la chaudière. Contactez le
fabricant du composant pour le remplacement si
les instructions sont manquantes. Ne pas installer,
démarrer, faire fonctionner, entretenir ou entretenir
cette chaudière sans lire et comprendre toutes
les instructions des composants. Ne laissez pas
la chaudière fonctionner avec des composants
modifiés, déconnectés ou sautés. N'utilisez que des
composants de remplacement identiques à ceux
fournis à l'origine avec la chaudière et le brûleur.
A.
ALWAYS INSPECT INSTALLATION BEFORE
STARTING BURNER.
B.
FILL HEATING SYSTEM WITH WATER.
Failure to clean the system will result in erratic water
lines and surging, and other improper system operations.
Le fait de ne pas nettoyer le système entraînera des
conduites d'eau irrégulières, des surtensions et d'autres
opérations incorrectes du système.
CLEAN HEATING SYSTEM IF boiler water or
condensate return water is dirty or if erratic water lines
or surging exist after a few days of boiler operation.
Refer to Paragraph (F) for proper cleaning instructions
for steam and water boilers.

1. STEAM BOILERS - Fill boiler to normal water
line. As shown in Figure 1, the normal water
line is 45¾" from the floor. At the start of each
heating season and once or twice during the season
try SAFETY VALVE to be sure it is in working
condition. To do this, fasten wire or cord to lever of
valve and pull lever—standing safe distance away
from valve.
2. HOT WATER BOILERS - Fill entire Heating
System with water and vent air from system. Use
the following procedure on a Series Loop or Multi-
zoned System to remove air from system when
filling:
a. Close isolation valve in boiler supply piping.
b. Isolate all circuits by closing zone valves or
balancing valves.
c. Attach a hose to hose bib located just below
isolation valve in boiler supply piping.
(Note - Terminate hose in five gallon bucket at a
suitable floor drain or outdoor area).
d. Starting with one circuit, open zone valve.
e. Open hose bib.
f. Open fill valve (Make-up water line should be
located directly above isolation valve in boiler
supply piping).
g. Allow water to overflow from bucket until
discharge from hose is bubble free for 30
seconds.
h. Open zone valve to the second zone to be
purged, then close the first. Repeat this step until
all zones have been purged, but always have one
zone open. At completion, open all zone valves.
i. Close hose bib, continue filling the system until
the pressure gauge registers normal system
design operating pressure. Close fill valve.
(Note - If make-up water line is equipped
with pressure reducing valve, system will
automatically fill to normal system design
operating pressure. Leave globe valve open).
j. Open isolation valve in boiler supply piping.
k. Remove hose from hose bib.
Do not operate boiler with pressure above
maximum allowable working pressure listed on the
Boiler Rating Label.
DO NOT draw water from boiler while in use. When
adding water while boiler is in operation, do not
open supply valve fully but add water slowly.
