GSA Gas-Fired Steam Boilers – User's Information Manual
Please read this page first
Failure to adhere to the guidelines on this page can result in severe per-
sonal injury, death or substantial property damage.
Service and maintenance
1. To avoid electric shock, disconnect electrical supply before
performing maintenance.
2. To avoid severe burns, allow boiler to cool before performing
maintenance.
3. You must maintain the boiler as outlined in the manual and have
the boiler started up and serviced at least annually by a qualified
service technician to ensure boiler/system reliability.
Boiler operation
4. DO NOT block flow of combustion or ventilation air to boiler.
GSA boilers are equipped with controls which will automatically
shut down the boiler should the vent be blocked. Should the
boiler shut down due to blockage, these devices must be reset
or replaced only by a qualified installer/service technician.
5. Should overheating occur or gas supply fail to shut off, do not
turn off or disconnect electrical supply to pump. Instead, shut
off the gas supply at a location external to the appliance.
6. DO NOT use this boiler if any part has been under water.
Immediately call a qualified service technician to inspect the
boiler and to replace any part of the control system and any
gas control that has been under water.
7. Have the building monitored when it is vacant for an extended
period. Safety controls can shut down the boiler at any time.
The loss of heat can result in significant damage due to freezing.
Boiler water
8. DO NOT use petroleum-based cleaning or sealing compounds
in boiler system. Water seal deterioration will occur, causing
leakage between sections and damage to heating system
components. This can result in substantial property damage.
9. DO NOT use "homemade cures" or "boiler patent medicines".
Serious damage to boiler, personnel and/or property may result.
10. Continual fresh makeup water will reduce boiler life. Mineral
buildup in sections reduces heat transfer, overheats cast iron,
and causes section failure. Addition of oxygen and other gases
can cause internal corrosion. Leaks in boiler or piping must be
repaired at once to prevent makeup water.
11. DO NOT add cold water to hot boiler. Thermal shock can cause
sections to crack.

Air contamination
12. To prevent potential of severe personal injury or death, check
for products or areas listed in table below before installing boiler.
If any of these contaminants are found, do one of the following:
• Remove contaminants permanently.
• Isolate boiler and provide outside combustion air. See
applicable codes for further information.
