SECTION IV - OPERATING INSTRUCTIONS
WARNING
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.
A.ALWAYS INSPECT INSTALLATION BEFORE STARTING BURNER.
B.FILL HEATING SYSTEM WITH WATER. Boiler must be cleaned and fully free of oil and dirt.
a.Close isolation valve in boiler supply piping.
b.Isolate all circuits by closing zone valves or balancing valves.
c.Attach a hose to bib cock 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 bib cock.
f.Open fill valve
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 bib cock, continue filling the system until the pressure gauge registers normal system design operating pressure. Close fill valve.
(Note - If
j.Open isolation valve in boiler supply piping.
k.Remove hose from bib cock.
CAUTION
Failure to clean the system will result in erratic water lines and surging, and other improper system operations.
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 41½” from the floor or bottom of casting. 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:
DANGER
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.
C.SET CONTROLS with burner service switch turned “OFF”.
1.PRESS RESET BUTTON on primary control and release.
2.On STEAM BOILERS set
3.On STEAM BOILERS WITH TANKLESS DOMESTIC WATER HEATERS, set boiler water temperature dial on low limit operating control at 190°F (max.). Set differential at 10°.
